MULTIDISCIPLINARY OCEANOGRAPHY The department has in the past reported itsresearch progress separated into the various scientificdisciplines.These often tend to be artificial boundaries as more andmore research activities involve sci- entists and techniques frommany areas of study. In an attempt to prevent repetition and redundency, this section called Multidisciplinary Oceanography will precede the othersections. Coastal Oceanography COOC

Coastal Oceanography COOC is an interdisciplinary researchpro- gram for investigators to learn more about the interactions ofocean con- ditions, the pelagic food chain and albacoretuna off the Oregon Coast. Upwelling and the Columbia River plume, phenomena that dominatethe ocean off Oregon during the summer, receive special attention.This study consists of several interdependent projects.See also: Local Winds- Pattullo, Detweiler, page 9.

PHYSICAL OCEANOGRAPHY

Atmospheric Effects on Incoming Solar Radiation Over Tropical Oceans - Quinn, Burt "Prediction of Abnormally Heavy Precipitation over the Equatorial Pacific Dry Zone, " was published in February in the Journal of Applied Meteorology. Solar radiation data are now being recorded at the tropical North Pacific sites:Johnston Island 16°45'N, 169°31'W, Majuro Atoll 7°05'N, 171° 23'E, and Kwajalein Atoll 8°501N, 167° 36'E.The official starting date was 1 February 1970, however, Majuro has been recording since 1 December 1969. A program has been developed through theNational Weather Records Center, Asheville, to obtain the necessary weather data in support of this project.ATS-I satellite pictures of the tropical Pacific, for the involved period, are being received through the courtesy of the National Environmental Satellite Center of ESSA.

Development of Forecast Techniques for Wave and Surf Conditions over the Bars in the Columbia River Mouth and at the Entrance to YaquinaBay- Quinn, Neshyba, Burdwell Columbia River bar closure intervals (closure to shiptransport) for the period January 1963 through the present were obtainedfrom the Columbia River Bar Pilots Associationby Mr.N.Kujala.The synoptic weather patterns and deep water waves and swell which lead up toand cause these bar closures will be studied indetail in order to develop a predictionscheme.Mr. Dave Enfield, a student oceanographerwith meteorological training, will be working on the solution to thisproblem in his thesis research, The OSU buoy, TOTEM I, has now been instrumented so asto record deep water wave characteristics, and it is expectedthat such data should soon be available.

Modification of Precipitation on the Oregon Coast -Elliott, Burt, Egami, Rossknecht, Ramsey (Statistics) During the winter, in addition to our regular rain gaugeoperation, we used a specially modified rain gauge.We were able to record approxi- 3 mately 0. 0002 inches of precipitation for a three-day storm in late Feb- ruary.Analyzing these data by complex demodulation is revealing the fine-structure of the rainfall patterns as well as such problems as 're- verse' aliasing of the data and the non-stationanity of the time series. A modified tipping-bucket rain gauge was installed on the TOTEM Buoy to be compared with rain gauges on the shoreline. We found con- siderably less rain at sea, as revealed in the Table below. We attempted to measure condensation nuclei at sea aboard R/V YAQUINA in January.Due to mechanical and weather difficulties only a few samples were taken but these indicated much less cloud-condensation nuclei than found on the Coast.

We havenot yet analyzed the filter data but we have found indicationsthat the Aitkennuclei counts at sea do show the influence of land out to several hundred miles.

Model Study of Double Kelvin Waves- Caldwell We have obtained sequences of streak photographs of oscillatory modes trapped on the edge of a circular sill ina rotating basin.The dis- persion curve agrees well with Longuet-Higgins' calculations except at long wavelengths where the curvature of the sill is probably important. Two modes have been found, and possiblya third.The higher modes also follow the calculated dispersioncurve.

EdgeWaves ina RotatingModel - Caldwell, Cutchin In order to investigate the modes of wave motion present on a shelf with an exponential depth profile,we have constructed a circular shelf with such a profile on the rotating table.Preliminary results show that the calculations of Buchwald and Adams, extended by Longuet-Higgins to non-zero divergence, predict the dispersion relation for the first and second modes quite well.

Potential Temperature of Seawater- Caldwell, Culberson Recently it was discovered that convection is started in seawater initially at rest by finite-amplitude disturbances rather than infinitesimal perturbations (seePapers in Press, page 82 ).The temperature gradient in a layer of seawater can be dependentupon the history of the system, and can be a decreasing function of heat flow in certain regimes.Experi- ments are now under way to investigate this effect in pure water in order to understand its origin.

Structure of Oceanic Currents- Sakou, Neshyba, Still, Gilbert An array of moored buoy stations has been established and is in operation for sensing oceanic currents over the continental slope off Ore- NOV 1968DEC 11969 JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV CURRENTMETERFIXED 12040m8Om m CURRENT METER "1 120 m40m80 m II CURRENTMETER 80m 2 120 m 40m Lost during retrieval I`?1560000

Mesoscale air-sea interaction- Sakou The continuation of the earlier effort to make analogue and num- erical simulation of the localized Ekman model with the temporary vary- ing wind stresses is combined with the study of inertial motion as ob- served at buoy-current meter stations.The inertial period motion as extracted by complex demodulation procedure from the observed ocean current time series is well correlated with the local wind stress varia- tion.For the case studied the simple linear model could reproduce more than 90% of the inertial period energy from the input record of wind stress over the preceding 30 hour period.The numerical simulation of Belyaev's theoretical-spectral model confirmed the result of the analogue calcula- tion that demonstrates that the ocean responds to variable wind stress as if there were a window of momentum transfer at around the inertial period.The study will continue to combine theoretical, numerical and experimental effort to uncover the mechanism of transfer of momentum and the partition of energy among the different frequency bands.

Air-Sea Interaction (Mesoscale) - Hasse A study on the relationship between geostrophic and surface wind at sea has been completed.The following is an abstract: 7

The ratio decreases withincreasing geostrophic wind and increasing stability.While stability is an important parameter for light to mod- erate winds, variation of the ratio with geostrophic wind speed can not be neglected taking the full range of geostrophic wind speeds into consideration. From the Navier-Stokes equations such a variation is to be expected.For light winds, the (local) surface wind may exceed the (mesoscale) geostrophic wind.Both effects together can be des- cribed approximately by a linear relation between the surface wind and geostrophic wind, with a slope of .56 and a constant term b>0 varying with stability.The residual error was 2 m/sec.Variation with latitude is inferred from the Navier-Stokes equations. The deviation of the temperature of the sea surface layer (thick- nessof order 0. 1 mm) from the water temperature at a depth of one meter has been studied.Extreme deviations of from -I to - 1. 5 C have been recorded, which could affect transports of sensible and latent heat through the interface.These temperature differences make it difficult to construct meaningful synoptic sea surface temperature maps from different kinds of observations such as radiation temperatures and in- take or bucket temperatures.The study is being carried out by analysis of published observations and numerical calculation with variation of ex- ternal parameters.

Air-Sea Interaction - Pond, Phelps, Paquin, Frye, Dorman Much of the time during this period was spent in developing a more versatile and economical data processing system. Some preliminary analysis of the data from the pre-Bomex cruise on FLIP in February 1969 was done.Like the November 1968 data (paper in the Journal of Atmospheric Science, March 1970) these data show a strong correlation between temperature and humidity fluctuations.The flux spectra have similar shapes so that one flux can be predicted from the other.The data obtained during Bomex are different.The temperature and humidity fluctuations are not so well correlated particularly at low frequencies. The humidity spectrum has more power at low frequencies relative to high frequencies than the temperature spectrum. Some preliminary analysis of the pre-Bomex data in terms of structure functions was done.By measuring third order structure func- tions and normalizing them with second order structure functions it is 9 possible to obtain values for the Kolmogeroff constants for velocity, tem- perature, and humidity.This methodis the only practical one for meas- uring the humidity constant.Knowing the value of these constants it is possible to make estimates of the fluxes from the second order structure functions (or the spectra). We plan to make these measurements and compare them with flux values obtained by the eddy correlation technique. If this way of estimating the fluxes is reliable, it will make underway shipboard measurements feasible since structure function can be meas- ured more easily than the eddy correlations.Only a small amount of data (one five minute record) has been examined so far, so no strong conclusions should be drawn.The value obtained for Kl, the velocity constant, was 0. 75.The accepted value is 0. 5 so the result is some- what anomalous although Carl Gibson has reported similar values by direct measurements during Bomex.In our case it may just be the par- ticular record chosen.The jalues for the temperature and humidity con- stants depend on Kl.With K = 0. 75, the measured value, K9=0. 7, KT = 0. 8; with Kl = 0. 5, the accepted value, K9 = 0. 9, KT = 1. 0.The values for KT are in the range obtained at the University of British Col- umbia which is encouraging.One may at least hypothesize that KT and K9 have about the same value. The development of our sonic anemometer was continued during this period in preparation for a cruise in May. During March, Pond took part in the Chilean Inlets leg of the Hud- son 70 cruise. A fairly complete survey of the whole of the Chilean in- lets system was done including physical, chemical and some biological measurements.

Optical Oceanography- Beardsley, Pak, Zaneveld, Plank The data collected during the long cruise YALOC 69 to the eastern equatorial Pacific continueto supply interesting results, and three new papers have been prepared and submitted to the IUGG for presentation in Tokyo in September.The abstracts of these papers follow: Near Bottom Nepheloid Layers in the Eastern Equatorial Pacific Ocean Near bottom waters at 23 hydrographic stations surrounding and east of the Galapagos Islands in the Eastern Equatorial Pacific Ocean were sampled in an effort to locate and measure near bottom nepheloid layers.Light scattering of the suspended particles was 10 determined using a Brice-Phoenix Light Scattering Photometer and the concentration of suspended particles was also measured directly using a Coulter Counter.Bottom nepheloid layers were observed in the light scattering data at stations located over topographic ridges and conti- nental slopes but were not observed at stations located in a flat abyssal plain.The values of light scattering observed in the nepheloid layers ranged from R (45) = 1. 5 x 10-3 to 6. 0 x 10-3 (meter- steradian) -1 which is an increase of about a factor of 2 from the water above.The neph- eloid layers were approximately 200 to 500 meters thick, and in about half of the cases the bottom of the nepheloid layers were adjacent to the bottom of the ocean, while a thin layer, less than 100 meters thick, of clean water free from nepheloid material was sandwiched between the nepheloid layers and the bottom of the ocean in the other half of the cases.It was also found that the specific light scattering increases with depth in the nepheloid layer and the values of this specific light scattering are all in range between the characteristic region of clay and kaoline.The concentration of particles larger than 1. 75 microns did not show a significant change corresponding to the nepheloid layer. This fact could be explained by assuming that the increase in light scattering is caused by an increase of smaller particles or by assuming that the particle's relative index of refraction in the nepheloid layer is larger than in the layer above.In either case it appears that the source of the nepheloid material is not located in the superadjacent water. The Cromwell Current Near the Galapagos Islands During February 1969 the Cromwell Current was traversed by two North-South series of hydrographic stations along 920001W and 91° 40'W longitude.The western edge of the Galapagos platform, formed by the islands Isla Isabella and Isla Fernandina, lies at approximately 30 and 10 nautical miles west of the platform.The section taken along 92°00'W shows typical Cromwell Current features in oxygen, temper- ature, and salinity, while the section closest to the Galapagos Islands seems to indicate a splitting of the current into a northern and southern branch. As indicated by the 2. 75 ml/l oxygen concentration profile, the core of the current extends to 280 meters at 920001W and reaches from 00501S latitude to 0° 15'N latitude.At 910401W the core extends to 260 meters and reaches from 1°20'S to 0°50'N,The current is typically indicated by a weakening of the thermocline.The temperature data show the widening of the current near the islands. A salinity max- imum greater than 35. 2% is found in the core of the current. A para- chute drogue released at 100 m depth 15 miles west of Isla Isabella on the equator, moved in a northeasterly direction with a speed of about 1 knot.Comparison of oxygen profiles shows presence of Cromwell 11 Current water, as indicated by an oxygen concentration maximum be- tween 150 m and 250 m depth, as far north as 3°30'N and as far east as 88°W indicating a possible northeast deflection of the current by the Galapagos platform. At all stations light scattering, beam extinction, and particle size and concentration were measured, and compared with typical pro- files of these properties in other regions of the eastern equatorial Pacific.The Cromwell Current appears to have an optical and particle signature consisting of a slight but definite maximum within the core. The usual near-surface nepheloid layer weakens above the borders of the current.The apparent splitting of the current was also observed in the optical data. Light Scattering Vectors, Particle Size Distributions, and Oxygen Profiles in the Eastern Equatorial Pacific Particle size analyses were made on YALOC 69 for the waters between Oregon and Peru.The particle size distributions (for particles larger than 1. 13 microns) were essentially exponential in shape, but it was estimated that between 60% and 90% of the particles were smaller than 1. 13 microns.The typically exponential shape suggested that a decay or decomposition mechanism is dominant in determining the par- ticle size distribution,in the open ocean.This relative homogeneity of distributional shapes allowed the total measured particulate surface area and the total measured particulate volume to be expressed as lin- ear functions of the total measured number of particles of each sample. Significant increases in particle number were found in the nearshore and equatorial upwelling regions, while the relatively stable subtrop- ical waters contained fewest particles.Here also were found the pre- dominant number of near-surface turbidity maxima at the depths of the respective discontinuity layers.The particle number generally de- creased monotonically with depth except for those stations with a tur- bidity maximum at the pycnocline.Particle size generally increased to a maximum at the pycnocline and then decreased with depth.No correlation was found between particle concentration and water type, nor between particle size distribution and water type. The volume scattering function at 45° and the particle size distribution as measured at several stations can be combined to create an optical vector consisting of the specific light scattering of the average particle and the cross section of the mean particle.Plots of the op- tical vector show a characteristic form, with a decrease in mean area 12 accompanying an increase in specific scattering in the water above the oxygen minimum, and little change below the minimum except in those areas with deep nepheloid layers.Above the oxygen minimum the con- centration of nepheloid material was proportional to the amount of dis- solved oxygen.The change in the optical vector with depth appears to be directly related to the oxidation of the decomposable parts of the nepheloid material, suggesting a mechanism for sustaining the oxygen minimum in spite of the oxygen-rich waters above and below it. William S. Plank participated in a cruise to the Panama Basin a- board the ESSA research vessel, OCEANOGRAPHER, during April and May, 1970.Volume scattering functions and particle size distributions were determined for water samples collected at 33 stations in the basin. Analyses were performed with a Brice- Phoenix Light Scattering Photo- meter and a Coulter Counter. In addition to preparing the papers listed above, we have completed development of a shallow water in situ beam transmissometer with reg- ulated power supplies for both the lamp and the high voltage for the photo- multiplier.Power for the unit is obtained from self-contained batteries and the device has a depth capability of 300 meters. A deep nephelometer is also under construction.It has been designed to measure light scatter- ing at 450 at depths of up to 7, 000 meters.This device utilized a DC to FM converter so that a variable frequency is sent up the conducting cable. In this way we are able to avoid problems with slip ring noise and cable losses.This unit will eventually be used with a small pump and a remote Niskin sampler to measure the concentration of particles in the deep neph- eloid layer.

Hydrological Optics - Beardsley, Hodgson, Zaneveld A review of all presently available theories on the prediction of the modulation transfer function of seawater has been made.This review will be presented at the AGARD-NATO "Electromagnetics of the Sea" con- ference in Paris, June 22-26, 1970.The abstract follows: Image Degradation over Seawater Paths -- A Review When an underwater object is viewed by a submerged image forming an optical system, the quality of the image is always degraded in comparison with the same geometry in air.This degradation is a complicated function of the scattering of the water, the particles in the water, the absorption of light along the path, and the geometry of the 13

R. V. Zaneveld and G. F. Beardsley, Jr.,JOSA. 59(4); W. H. Wells, JOSA 59(6); and F. Chilton, D. D. Jones; and W. K. Talley, JOSA 59(8). These three papers utilize analytic numerical, and Monte Carlo tech- niques.The methods, limitations, and results of each paper are com- pared and the applicability of each approach to typical submarine view- ing situations is discussed. A new solution to the axially symmetric submarine lightfield has been found.This solution enables the prediction of the near-asymptotic submarine lightfield as a function of the inherent optical properties and the asymptotic decay coefficient. Under consideration also is a theoretical solution to the modulation transfer function of seawater, which eliminates the restrictions imposed by previous models. For the past six months, we have been preparing apparatus which will be used to measure the modulation transfer function (MTF) of sea- water.Preliminary MTF measurements were taken of solutions contain- ing a variety of suspended particles.The data was analyzed in light of existing theory and the exponential behavior of the MTF appears verified. A complete systems analysis of our apparatus was conducted and the re- sults used to increase the resolution of the measurement procedure.Our current measurement technique records optical irradiance distributions in real time rather than going through the intermediate process of record- ing the information on film and subsequently reading the film with a micro- densitometer. A typical set of line spread functions is shown in the fig- ure. A in Figure 3 is the line spread function for a distilled waterpath and B is for a solution of gelatin with a 10 times increase in sensitivity.

Arctic Oceanography - Neal, Neshyba, Amstutz, Hansen Brief Report of T-3 Cruise, November 11-23, 1969

Purpose of Cruise: 1)To measure density changes in the fine-layered structure in the depth zone 200 to 500 meters.2)To make initial con- tinuous profiles of oxygen in the same depth zone.3) To measure vel- ocity shear associated with fine structure.4) To make initial measure- ments of internal wave activity associated with the fine structure.

(1) and (3) were accomplished;(2) and (4) were not.

Data:Figure 5 is a typical profile of temperature, conductivity, com- puted salinity and sigma-t from this cruise.The step structure is re- markably well-ordered and persistent. We extracted over 160 separate step measurements from the data, and plotted histograms of AS, A T, and AU-t,the differences of salinity, temperature and density across these steps, as shown in Figure 6.The histograms on the right side result from smoothing the raw data on the left through a filter of width 4 units. It is clear that for this depth zone, the salinity and sigma-t dis- tributions are markedly peaked.Shown superposed are normal distri- butions of like mean and variance as the raw data.The fit of the normal to smoothed OG"t is quite good.But it is difficult to accept the fit of the normal to smoothed S. Figure 7 is an attempt to fit a smoothed normal of mean 11 ppm and variance 2 ppm, to the smooth S. The fit is now good over the central portion of the histogram, but leaves residuals on either side of the main lobe.The residual at smaller valves of AS can be satisfactorily explained as due to disruption of interface zones by Kelvin- Helmholtz instability.Several "half-steps, " which would be pro- duced by Kelvin- Helmholtz breaking waves, can be seen in Figure 5.The residual at higher values of AS is not as easily explained. We are still working on this aspect. 040 U4)U)a) ...... r4 U] ... 4oCd Zi O 014 0 04 V ,on vD U)0 CdOacd o.o Cd U Q)U)O ,>1 --i41 Cd0 0 cd0 .-C.t' rO U] 4-4 01-4 U 0U)(d a cd 00. 18

Local Winds- Pattullo, Detweiler

Since March 1969 we have been observing the local wind above the beach west of the Marine Science Laboratory at Newport.The instrument was provided and installed by the Weather Bureau and the records are tended and serviced by Mr. Burdwell.The purpose of the work is to eval- uate the suitability of using geostrophic winds computed from weather maps for comparison with (and eventually for prediction of) ocean currents, particularly mesoscale phenonema such as upwelling.The records also provide to other projects in the department a ready source of information on winds.

As a portion of the work for the M. S. degree Detweiler has devised a method for estimating hourly mean winds from the records, has devel- oped a formula to represent the variability during each hourly interval and has summarized the recorders for the first eight months of data (up- welling season 1969) (see COOC, page 1).It is proposed in the near future to:(a) continue reduction and summarization of the remaining records (at present the months through April 1970 have been recorded),(b) to automate the recorder to save personnel time and to expedite processing of data, and (c) complete a comparison now under way between the geo- strophic and observed winds. 20 Hydrography of Oregon Waters- Pattullo, Wyatt, Barstow,Gilbert, Washburn, Jones Monthly hydrographic cruises were continued off Oregon with par- ticular emphasis on the Newport Line.Cruises were jointly made with Biological and Chemical Oceanography sections to obtain greater station coverage.Cruises were also made to Puget Sound in January and the Gulf of California from February to April in conjunction with optical studies.

Coastal Oceanography (COOC) (see page 1):A multidisciplinary coordinating group has been functioning informally throughout the year to plan joint local cruises and prepare for mutual study and interchange of data and results.This group has consisted primarily of Smith, Gordon (also representing Park), Curl, Small, Pearcy, and Wyatt with their students, but virtually all the staff have participated at one time or another in the planning, operations at sea, or seminars on Coastal Oceanography. At present Mr. Wyatt is coordinating development of a set of maps and sections to be generally used in this work to make inter-comparison of different observations and summaries more feasible and to encourage full and efficient use of the data.

Wind-wave Properties - Beardsley, Earle Three three-component spherical drag probes which use variable inductance devices as displacement transducers have been built, calibrated, and used in the field.The associated electronics provides voltage outputs which are proportional to the three components of force acting on the 21 spherical sensor of each probe. A numerical predictor-corrector com- puter program has been written to obtain the three velocity components from the three voltage outputs of a single probe.The probe design, op- erating theory, and calibration procedure is described in "A three com- ponent drag probe for the measurement of turbulent water velocity fluctua- tions"Rev. Sci. Instr. June, 1970. A description of the probes was presented in a paper at the fall AGU meeting, December 1969, in San Francisco. Several hours of wave height, two mutually perpendicular wave slopes, subsurface wave pressure, and subsurface velocity data have been obtained in Yaquina Bay, Oregon.Subsurface wave pressure and subsur- face velocity have been measured for several hours from the stable TOTEM buoy which is moored in deep water 30 miles off the Oregon coast. Analysis of this data is now in progress.The analysis computer programs include a predictor-corrector numerical iteration to obtain the three components of water velocity from the drag probe voltage outputs, a fast Fourier transform program to obtain energy spectrumsand cross spectrums of digitized time series, a filter program to compute the wave orbital velocity components (as predicted by first and second orderwave theory) from records of surface wave height and wave slopes,a direction- al energy spectrum program to determine the first five Fourier coefficients of the directional energy spectrum from measurements ofwave height and wave slopes and also frommeasurementsof the three subsurface velocity components, a turbulent velocity program to remove the theoretical wave orbital velocities from the measured velocities, anda momentgenerating program to yield the moments and the amplitude probability density func- tion for a digitizedtime series.

Temperature Variability over the Borderland- Mesecar, Neshyba, Sakou, Pawley, Plutchak

Three sets of thermistor array were fabricated and the field test was made. The positioning of the array was coordinated with that of cur- rent meter array in order that a broad range of correlationamong the variables defining the environment might be studied.The recovery of the data in a satisfactory manner has not been made. A new set of experi- ments for 1970 is being planned and an extensive work is in progress to uncover the weakness in the data acquisition system and to improve it. The initial phase of the study is confined to measuring the entire spectral range of temperature variation in the upper 300 meters where the varia- tion may be correlated with the propagation of internalwaves, transient 22 features of upwelling, turbulence, etc.This study is expected to contri- bute to the delineation of the temporal structure of kinetic and potential energy distribution which is also being studied by an array of current meters.

Physical Oceanography of Shelf and Slope Waters- Pattullo, Pillsbury, Smith, Cutchin, Enfield, Huyer

A data report covering observations taken during1967and 1968 has been completed but not yet distributed.These data will form the maj- or source for the Ph.D. thesis now being written by Dale Pillsbury.All data collected during 1969 (observations of temperature and wind) have been processed and elementary statistics have been computed.These data were coordinated with the joint COOC group in the department (see page 1) and multidiscipline analysis and interpretation will be under- taken.Miss Jane Huyer, ' a student from Canada, has joined the group and will study the implications of the 1969 data as a part of her research work for the M. S. degree.

SurfaceSeawater CharacteristicsDuring the Uj2welling Season (Heat Budget) - Pattullo, Evans During 1969 many near-surface temperature and salinity observa- tions were made above the shelf offshore, partly as a part of COOC (see page1), and continuing hydro measurements and partly special-pur- pose such as for Albacore Central use (see Pearcy, page 58 ) and for current studies (see Pattullo et al., page 20 ).An analysis of implications from these data, including the heat storage, is under study by Mr. Evans on a part of his thesis work for the M. S. degree.

Sea Level Studies - Pattullo, Pittock Mr. Pittock, a prospective Ph.D. student, has begun to examine the digitized records from the Newport Tide gauge.The first step is to error-check all the data and second is to examine the principal features of the deviations from predicted tides. 23

GEOLOGICAL OCEANOGRAPHY

Structure of the Oregon Continental Margin - Kulm, Fowler,Bales, Buehrig, Ness Approximately 7, 000 kilometers of continuous seismic reflection profiles are being studied to determine the basic structural framework of the Oregon continental margin.The structural framework is being integrated with the stratigraphic studies to develop an integrated picture of the origin and development of the margin during Late Tertiary time.

Marine Geology of the Southern Oregon Margin - Kulm, Spigai A three-dimensional geological-geophysical study of the southern Oregon margin is nearing completion. A model for Holocene and Late Pleistocene sedimentation has been developed for the region.Sediment sources have been determined for the Late Cenozoic Quaternary sediments through studies of the light and heavy mineral assemblages of the coarse grained constituents and the clay mineral assemblages of fine grained con- stituents of the unconsolidated and consolidated deposits.

Cascadia Basin Studies - Kulm, Phipps, Ness Continuous seismic reflection records of the deposits of Cascadia Basin are being analyzed for the acoustic nature of the sedimentary de- posits, their thickness and distribution over the entire basin.Sediment distribution and structure of the basin are being related to plate tectonics of the region. The structure of all deep-sea channels in the basin is being studied to determine the nature of their origin and development.

Sediments of the Gorda and Juan de Fuca Ridges - Kulm, Phipps, Scheidegger Cores collected on these two spreading ridges are being studied for their clay and silt mineralogical composition to determine the source of the hemipelagic and pelagic depostis.Preliminary analyses show that the sediments of the two ridges are derived from at least two different 24 continental sources. Ash layers in these deposits are being analyzed by means of neutron activation analysis and a variety of optical, methods.

Geophysicaland Geological Studiesin the South Atlantic - van Andel, Heath, Moore

The geophysical portion of the work on CIRCE cruise between Luanda, Angola, and Fortzleza, Brazil, has been completed.The mat- erial obtained on this cruise consists of bathymetric, magnetic, and seis- mic reflection data along a traverse across the Mid-Atlantic Ridge at 60- 8* S latitude, and detailed geophysical surveys in five small areas on the crest and east flank of the ridge, and across the Ascension Fracture Zone. Except for the last area, all material has been interpreted;the results are contained in two papers (van Andel and Moore, 1970; van Andel and Heath, in press).Based on the geomagnetic profile as a time base, the rate of seafloor spreading in this part of the South Atlantic appears to have accelerated twice, approximately 40 and 4, 5 million years ago, and decelerated at least twice, 38 and 10 million years ago.Accelerations were accompanied by uplift and normal faulting of the central part of the ridge, while decelerations produced subsidence with modest contraction. The effects of the uplifts are clearly present in the reflection data.Spread- ing without creation of significant relief occurred on the ridge until approx- imately 5 million years ago.This process produced a low relief with small rifts, strongly reminiscent of the present crestal topography of the East Pacific Rise. A very linear secondary relief parallel to the ridge axis developed later by faulting on the flanks.Portions of the crust that were near the crest during periods of uplift are more intensely faulted than those that were remote at all times.The importance of the last phase of uplift and associated faulting is reflected by a decrease in the fault density away from the ridge crest. The present crestal zone is different from the flanks and the older crests;the relief is nearly ten times greater, transverse disturbances are common, and there is conflicting evidence regarding its age.This striking change indicates either a recent change in the spreading process or a recent period of strong deformation.

The data for the Ascension Fracture Zone will be supplemented by additional information to be collected on a cruiseof R/V CHAIN of Woods Hole Oceanographic Institutionin May/June.Preparation of a paper awaits arrival of this material. 25 Changes in spreading rate affect the thickness of sediments on the ridge, since most of the sedimentation takes place on the central, highest part of the ridge above the carbonate compensation depth.Thick sediments will accumulate during slow spreading, while rapidly formed crustal sec- tions will have thinner deposits.The sedimentation thickness is also a function of the water depth relative to the position of the lysocline and com- pensation depth, and hence a function of uplift and subsidence of the ridge as well as temporal depth fluctuations of compensation depth and lysocline. Consequently, the ridge flanks do not show a uniform increase in thickness away from the crest. We are attempting to study the depositional history of the ridge from this point of view by means of a computer modeling pro- gram that takes the principal variables into account. Geophysical data are also available for the previous leg of CIRCE cruise from Mozambique to Luanda.In addition to much underway mater- ial, this includes a detailed survey of the crest of the Walvis Ridge, a de- tailed survey over the Walvis Shelf off Walvis Bay, and reflection data for a large field of diapirs on the continental slope off Angola. We have com- piled most of the material on the latter and are preparing the paper, while the first two subjects are being compiled now.

Sedimentation in the Panama Basin- van Andel, Heath, Moore, Drake, Malfait This program is designed to study in detail the processes of deep- sea sedimentation, erosion, and. postdepositional modification of pelagic sediments in the eastern Equatorial Pacific.In cooperation with Dr. Hein- richs we have compiled much of the available regional geophysical data, including material from Scripps and Lamont, and have prepared a new bathymetric chart.Studies of the distribution of sediment thickness over the basin, of the magnetic anomaly pattern, and of fault patterns deter- mined from seismic reflection data are in progress.There are three categories of structures; block faulted ridges with mainly normal fault- ing, containing very close spaced faults affecting the entire sediment col- umn and clear evidence of post-upper Miocene uplift (Cocos, Carnegie, and Malpelo-Coiba ridges), a low central zone with considerable relief and little or no sediment, containing a young spreading zone, and a com- plex region of trenches and deep basins which occupies the eastern part of the Panama Basin between the Peru-Chile trench and the join of the Coiba Ridge and the Mid-American trench.The regional tectonics of the basin is still largely unresolved; at least five and possibly six crustal plates, the Cocos, Nasca, South America, North America, Caribbean and possibly Panama-Colombia plates may be involved. 26 The tectonic-geophysical study serves as a background for a reg- ional study of sediment patterns. We have collected samples near the surface from all cores taken in the area by Lamont and Scripps and in addition possess approximately twenty long piston cores from YALOC 69 cruise. We are at present in the process of determining carbonate con tent, biogenous silica content, grain size distribution, microfaunal com- position and mineralogical composition on all surface samples.This pro- gram began when our new laboratory facilities became available early in 1970. The sediments in the eastern part of the region are dominantly hemipelagic with a large component of continental debris.Westward, the carbonate content increases, and volcanic ashes are a conspicuous com- ponent in the sediments.Variations in the Peru and Equatorial Current systems result in vertical variations of the biogenous opal and calcium carbonate contents.

Separation of Pure Mineral Phases from Deep-Sea Sediments - Heath, Nelsen The installation of a digital X-ray diffraction system allows us to obtain high-precision mineralogical data on large numbers of deep-sea sediment samples.Such analyses will permit us to map subtle, as well as known major distributional features.However, to obtain an accurate picture of deep-sea sedimentation, and particularly to develop a quanti- tative model of sedimentation which will allow us to predict paths and rates of deposition, as well as properties of sediments, within major oceanic provinces, the data must be accurate as well as precise.To date, the X-ray diffraction characteristics of sedimentary minerals cannot be pre- dicted on theoretical grounds, but must be derived from pure samples of the mineral in question (external standards).Because of the variability of each mineral, the only satisfactory standards are those derived from the deep-sea sediments themselves. This program, which will be the subject of a master's dissertation, involves the use of heavy liquid gradients to separate deep-sea sediments into their component minerals.The equipment needed to prepare the gradients has been built, and experiments to determine the optimum treat- ments required to break down mineral aggregates and produce stable dis- perions are in progress.

Stratigraphy and Sedimentation in the Panama Basin-Moore, Dinkelman During the past several decades the Panama Basin and the adjacent waters of the eastern tropical Pacific have been of particular oceanographic 27 interest, for it is in this region that the fertile waters of Peru current merge into the equatorial current system.It might be expected that the northward flowing waters of this cool current exert a strong influence on the faunal assemblages of the Panama Basin.However, this influence might well have varied corresponding to the changing atmospheric and oceanographic conditions of late Pliocene and Quaternary.The initial descriptions of cores from the Panama Basin indicate several alternating layers of siliceous and carbonate rich sediments.It is the purpose of this part of the Panama Basin study to determine the nature and time sequence of changes in oceanographic conditions suggested by these changes in lith- ology.This will be accomplished by relating the present day distribution of radiolarian and foraminiferal faunas to a detailed stratigraphic study of the cores.The assemblages of planktonic Foraminifera may provide additional information on variations in the corrosiveness of bottom or interstitial waters.All such information gives us insight into the paleo- oceanographic history of this region expressed in terms of productivity changes in the surface waters, changes in the directions and magnitudes of currents, and finally, climatic changes of the late Cenozoic.It will be of particular interest to relate the indicated climatic changes in this region, which is strongly influenced by a major current of the southern hemisphere, to the more thoroughly documented oceanographic changes of the northern oceans.

Nature and Concentration of Suspended Matter in Near-Bottom Water Masses - Heath, Dauphin, Beer This program is being carried out jointly with the optical Oceano- graphy group.So far, a study of the scattering characteristics of sus- pended mineral grains as a function of particle size has been completed and submitted for publication. A prototype pump system designed to sample suspended matter in deep water will be tested later this year.This system will use a constant pressure pump and low-ash filters to collect the suspended matter from large volumes of water.In situ filtering has been chosen over large vol- ume samplers and shipboard filtering to overcome severe contamination problems which have plagued earlier investigations of this type.The filter system will accompany a package of optical sensors on deep casts, so that the characteristics of the recovered suspended matter can later be related to in situ optical properties of the water. 28 Economic Potential of Placer Sands on Oregon Continental Margin - van Andel, Kulm, Bowman The Oceanography Department, in cooperation with the USGS and the U. S. Bureau of Mines, has conducted studies which evaluate the poten- tial of heavy mineral placers lying off southern Oregon.Sufficient data now exists on the topographic and structural configuration of the continental shelf, the distribution of heavy minerals, and magnetic anomalies that we may make reasonable inferences regarding the spatial distribution of these plac e rs. The identification of the opaque minerals and determination of the ore tenor are the remaining unknowns in any estimate of the in situ min- eral values.By magnetic separation and X-ray diffraction analysis, we have identified the opaque minerals in a heavy mineral concentrate from an onshore, raised Pleistocene terrace. A quantitative estimate of the abundance of these minerals is presently being carried out.Further work on this sample will include analysis for nickel, zinc, and platinum metals by atomic absorption and neutron activation techniques. Chromium and titanium are major components of minerals present in the sample and will be included in an economic analysis.Analysis of the spatial distri- bution of the heavy mineral accumulation on several known raised Plei- stocene terraces and of the offshore placers will allow us to make estimates of ore reserves. A complete economic analysis will include costs of min- ing systems in the offshore environment, comparison of these costs with on-land exploitation of similar deposits and an examination of the demand for the metals involved.

Trace Elements in Mid-Ocean Ridge Basalts - van Andel, Corliss The elemental composition of 120 mid-ocean ridge basalts has been studied using high-precision instrumental activation analysis.This analysis included 16 elements and, combined with petrographic observa- tions, has revealed two significant features of these rocks:1) The slowly cooled interiors of submarine lava flows, which have undergone deuteric alteration during slow cooling, are depleted in several elements which are enriched in pelagic sediments and manganese nodules (Mn, Fe, Co, the rare earths, etc.).Many of these elements are excluded from the solid phases which crystallize from the melt during solidification and are thus concentrated in residual liquids.Some additional elements are mobil- ized during the deuteric alteration of early formed olivine.These com- ponents of the melt presumably occupy accessible sites (e. g. inter-gran- ular boundaries) in the hot, solid rock mass, and are mobilized by dis- 29 solution in seawater introduced along contraction cracks forming in the late stages of cooling.These solutions may be the metal-bearing "hydro- thermal exhalations" or "volcanic emanations" accompanying submarine volcanism that are often cited as a source of metals into the pelagic en- vironment.

2)Factor analysis and covariance plots of quenched pillow basalt data from several geographic areas along the Mid-Atlantic Ridge (from 45° N to 7° S) reveal striking inhomogeneities in the composition of the erupted liquids.The rocks from each area form a cluster of compositions which are unique, and distinct from the clusters of other geographic areas with almost no overlap. Consideration of experimental petrology data for the basalt-perid- otite system, and relevant partition coefficient data, indicates that. there are no reasonable fractional crystallization pathways between these com- positional clusters.Thus, at least part of the regional inhomogeneity is due to inhomogeneity in the initial liquids.Differences in composition of these liquids might result from differences in the composition of the upper mantle source or in the conditions of partial melting.

Deep-Sea Drilling Project, Leg 7- Heath Leg 7 of the Deep-Sea Drilling Project covered the western Pacific between Guam and Hawaii.Dr. Heath served as one of the geologists re- sponsible for the lithological descriptions of the cores.The seven sites drilled covered four geological provinces: 1)The Marianas Basin, east of the Marianas Trench. A site in this Basin encountered basalt base- ment of late Cretaceous age- surprisingly young in the light of modern theories of plate tectonics; 2)The equatorial belt of biogenous sediments. Holes at three sites all penetrated calcareous oozes.This rapidly accu- mulating material should consititute ideal standard sections for biostrati- graphers.The striking acoustic layering seen in seismic reflection pro- files from this area is due to subtle variations in lithification of the car- bonate;3) The deep Central Basin between the Gilbert and Line Islands. Both sites in this area encountered remarkably uniform radiolarian ooze (acoustically "transparent" layer) over thinly bedded cherts.The lack of carbonate ooze suggests that this area has been near its present depth for at least 80 million years;4) The Hawaiian Arch, north of Oahu. This site, the least successful of the seven, encountered very hard vol- canic sandstone and mudstone. 30 The results of the preliminary studies of the core material have been written up, and will be published in the Initial Reports of the Deep- Sea Drilling Project.

Deep-Sea Drilling Project, Leg 8- Moore Leg 8 of the Deep-Sea Drilling Project was completed in November of 1969.Dr. Moore served as a specialist in the biostratigraphy of Radio- laria during this cruise.This year the nine scientists participating in this leg will publish an initial report on the accomplishments of their individual and joint studies. On board the GLOMAR CHALLENGER, Leg 8 sailed from Hawaii 4, 616 miles south along 140° W toTahiti.The primary objective assigned to this leg was to drill a series of holes across the equatorial belt of high productivity in the eastern Pacific Ocean in order to decipher the history of the equatorial current system.During Leg 8,eight holes (Sites 68 through 75) were drilled and 4, 019 feet of sediment recovered.Most of the sediment cored was calcareous nannoplankton ooze together with small- er amounts of calcareous siliceous ooze, radiolarian ooze, zeolitic red clay and basalt.Holes 70 through 75 completed the equatorial and south- ern parts (latitude 60N to 12. 50S) of a longitudinal profile of the eastern Pacific.Three major lithologic units can be recognized throughout this traverse.The lowest unit consists of radiolarian ooze, siliceous chalk and limestone, and chert of Eocene age.This is overlain by a middle unit of Oligocene-lower Miocene age consisting of calcareous nannofossil ooze with abundant radiolarians.This unit extends at least from site 42 of Leg 5 at 14°N to site 75 at 120301S.The upper unit, Miocene to Quat- ernary in age was found at sites 70 through 74.It consists of several facies including radiolarian ooze on the north and south, and thicker silic- eous and calcareous oozes occupying the equatorial region.Basalt was recovered beneath thin Eocene sediments at site 74 and beneath basal Oligocene sediments at site 75. A nearly complete Eocene to Quaternary biostratigraphic sequence was recovered with generally abundant radio- larians and calcareous nanno-fossils and rarer foraminifera, silico-flag- ellates and diatoms. Results indicate that the accumulation of sediments below the deep- er parts of the equatorial Pacific is significantly influenced by the rateof solution.Because of the effects of this solution, rates of productivity and former positions of the currents are difficult to determine.The pos- ition of the thickest early-mid Tertiary sediments is several degrees 31 north of the thick Quaternary and Late Tertiary sediments.This may in- dicate either a shift in the high productivity belt or movement of the sea floor.In addition, preliminary studies suggest that the calcium carbonate compensation depth was at least 1000 m deeper during the early to mid- Tertiary than it has been since.This resulted in a belt of mid-Tertiary sediments thicker and wider than that of the later Tertiary and Quaternary.

Deep-Sea Biostratigraphy, Planktonic Foraminifera - Fowler, Sumich Our studies of the stratigraphic distribution of planktonic foramini- fera in the area off Oregon and Washington are being concentrated on several deep-sea piston cores taken from the western flank of Juan de Fuca Ridge in the vicinity of Cobb Seamount. Additional data are being obtained from Cascadia Basin and surroundings and from late Tertiary rock samples that crop out on the Oregon continental margin. One particular core, 6709-20 (46° 04. 01N, 13100. 0' W), is providing most of the detailed strati- graphic information. Among other pursuits is a thorough assessment of the morphologic variation of Globigerina pachyderms (Ehrenberg) s. 1. Early observations of trends in color, weight percent CaCO3, radio- larian-planktonic forminiferan ratios and coiling direction of G. pachy- ., derma s. 1.led us to conclude that several alternating warm and cool per- iods were recorded in 6709-20.Using various combinations of sedimen- tation rates, based upon radio-carbon dates obtained from the top two meters of the core, a data of approximately 300, 000 years before present (B. P. ) was calculated for the bottom of the core.Recent determinations by Bruce Malfait and Dr. D. Heinrichs of magnetic polarity recorded with- in the core indicate that this estimate is small by a factor of probably more than two.If the bottom of the core is as old as it appears to be, then either average sedimentation rates were considerably lower than those estimated earlier or part of the section has been removed by erosion. There is reason to suspect the latter based upon various kinds of physical evidence in the core. A sample of light colored ash of probably contin- ental derivation from the very bottom of 6709-20 has been sent out for a possible fission track age determination. Another important point is that, if the age based upon magnetic polarity is correct, then a substantial portion, if not all, of the glacial Pleistocene record is present in the core.And, if this is true, G. pack - derma s. 1. demonstrate little or no coiling direction change in response to Pleistocene climatic changes. 32

Foraminiferal Biostratigraphy and Paleoecology, Continental Terrace- Fowler, Muehlberg Foraminiferal assemblages from more than 150 rock samples from the Oregon continental shelf and slope are being intensively studied to determine age and paleoenvironment.These data are being combined with the seismic reflection studies of the same area being conducted by Drs. L. D. Kulm and G. A. Fowler in order to establish the geologic history of the Oregon Continental Margin.Of particular interest is how the oceanic plate off Oregon interacts with the North American continental plate to form the continental margin. A stratigraphic column ranging in age from Middle Miocene to Pleistoce;.ze is being complied for the Oregon Margin.This column is in- complete in places due to the nature of the sampling and to limited expos- ures.In addition, at least two extensive unconformities interrupt the col- umn.Excellent correlations in terms of faunal similarities can be made with the Wildcat Section of northern California, the Elk River and Port Orford Formations of southern Oregon, and the Astoria, Montesano and Quinault Formations of the Grays Harbor Basin, western Washington. The traditional benthic foraminiferal zones of the Late Miocene to Plei- stocene sections of southern California can generally be recognized but correlations are being based primarily upon planktonic foraminiferal trends, particularly the coiling direction changes of Globerina pachyderms s. 1. Paleoenvironments ranged from inner sublittoral to abyssal with mostly bathyal faunas represented.Estimates of minimum relative up- lift of the Oregon Continental Margin since the Middle Miocene range up to approximately 900 meters.There are several indications that the rate of uplift has not been constant.In a few cases relative downwarping is required to explain the difference between paleo-depth and present depth at sample sites.

Foraminiferal Ecology, Oregon Sublittoral- Fowler, Gunther,Chang Since the last ProgressReport,Sea Grant Stations have been sam- pled on three cruises(C6911A, C7002, C7005)and samples of opportunity have been taken on two cruises for other purposes(C6910A, Y6910C).To date, a total of 323 foraminiferal samples have beencollected,plus a total of 122 sediment samples.All sedimentsamples,except for 7 from cruise C7005,have been processed for texturalparameters.Faunal counts have been completed for about 100 of the foraminiferalsamples;the rest have beenpreserved, washed,stained and are in storage awaiting faunal counts. 33

Preliminary statistical studies have been made on the partial fora- miniferal faunaldata.Multiple regression analysis of the relationship of the month of collection and water depth to individual specimen size in mic- rons indicates that water depth is more important for Eggerella advena and Bolivinapacifica,but for Uvigerina juncea the month of collection is moreimportant.However,other variables which could not be tested be- cause of incomplete data may be more important to test size than either of the twotested.Analysis of variance on total benthic foraminiferal standing crop after transformationby X = \X + 1indicates that standing crop depends more on sediment type than on season of collection.One station (SG-2, 200 mdepth,60% < % sand < 75% ) has a significant incr- ease in standing crop from winter to the next fall;this may be due to the incorporation of small- sized specimens into the zooplankton, either as part of the lifecycle,or as a result of storm-caused turbulence. 34

GEOPHYSICS

Marine Gravity - Banks, Couch, Gemperle, Heinrichs, Lu Free-air and Bouquer gravity maps of the Strait of Juan de Fuca have been completed.Interpretation of the gravity and other geophysical measurements of the region about the Strait of Juan de Fuca in terms the crustal and subcrustal structures is continuing. Free-air and Bouquer gravity maps based on measurements along 1750 km of trackline off southeast Alaska have been completed.Off Cross Sound a free-air gravity high greater than +60 mgl occurs over the outer edge of the continental shelf.This high separates, the gravity low, with valves between -40 and -80 mgl which occurs near the bare of the con- tinental slope and the low with values greater than-60 mgl which occurs near the coastline.Along Baranof and Chichagof Islands the axis of a moderate gravity high trends NNW-SSE just off the coastline.The shelf in this area shows no gravity low. A narrow gravity low extends along Lynn Canal and Chatham Strait.In Glacier Bay gravity anomaly contours are unclosed, negative and become less negative toward the southwest. Both the free-air and Bouquer anomalies show a marked change in charac- ter along the continental shelf in the vicinity of Cross Sound. A crustal and subcrustal cross-section, based on the gravity data and extrapolated refraction data, suggests the Moho depth between the coastline and Coast Mountains is approximately 25 km and under the Coast Mountains approxi- mately 35 km. Free-air gravity anomaly values from Panama Basin indicate that the region as a whole, including the Carnegie and Cocos ridges, is in iso- static equilibrium.However, several local, large, positive anomalies exist between the Coiba-Malpelo Ridge complex and the continent.The extent and trend of these anomalies are poorly defined by the existing track- line coverage.Gravity sections of the Carnegie Ridge, Cocos Ridge and Panama Basin, and northern extension of the Peru-Chile Trench are be- ing constructed.

Refraction Seismology - Couch, Johnson Calculations, based on seismic refraction measurements, show that crustal thickness in the North Cascade Mountains increases toward the south and decreases toward the west.Computed crustal thicknesses 35 combined with available gravity measurements indicate that either the crust or upper mantle is composed of rocks of relatively low density.The results of this investigation have been submitted for publication. A donation of a 12 channel amplifier and filter, cables and geophones greatly improves the department's seismic refraction capability.This equipment will be used in the future for crustal studies in the Pacific North- west.

Earthquake Seismology- Couch, Johnson, MacFarlane, Whitsett The World Wide Standard Seismograph Station at Corvallis was operated continuously during this report period.The seismograph records of the Klamath Falls and Portland (OMSI) stations have been read and cata- logued. The design of a portable microearthquake array has been completed and the subassemblies have been ordered. The maximum sensitivity of the microearthquake array depends on the background noise level or the microseismic noise level of the earth. In the Coast Range, an area under investigation, the noise level is high. Studies have been conducted to determine optimum filter settings which will provide a spectral window and effectively decrease the recorded noise level.Gains of a million were obtained with a band-pass filter set at 3. 5 and 20 Hz.The major microseismic energy appears to be contained in the frequencies near 0. 5 Hz.Several microearthquake events were re- corded in the Willamette Valley during a week of trial recording at high gain.

Heat Flow - Couch, Gemperle A regional heat flow map for the Northeast Pacific Ocean was com- piled from data collected at Oregon State University and other existing data.Higher than normal heat flow is found over the Gorda Ridge, the Blanco Fracture Zone, Juan de Fuca Ridge, and Explorer Ridge with the highest values on the east sides of the topographic features.Higher than normal heat flow measurements are also found along the continental mar- gin off Icy Straits and Dixon Entrance and in the Straits of Juan de Fuca. Average to below average values occur in the Scott Island Fracture Zone, west of the ridges and south of the MendocinoEscarpment. 36

Geophysical Data R eduction Computer Programs-- Gemperle, Keeling, Lu The documentation and user's manual was completed for the pro- gram package used to reduce and plot maps and profiles of bathymetry, gravity, magnetics, and earthquake epicenters. Modification and documentation of the program used to compute profiles of the vertical component of the gravitational attratction caused by a two-dimensional body was completed. A program to generate and plot magnetic anomalies for models based on the Vine-Matthews hypothesis was converted and modified. An additional program to compute and plot magnetic anomalies for arbitrary two-dimensional models was converted for use on the CDC-3300 computer.

Marine Magnetics- Banks, Couch, Gemperle, Heinrichs, Lu The pattern of recent spreading from the Galapagos Rift zone, and associated offsets within the PanamaBasin,has beenestablished.Basic- ally the present cycle of spreading started approximately 4 million years ago from two short active sections joined by an unnamed rift zone.Both centers are spreading at about3 cm/yrwith some assymetrical motion and local offset.The areas of active spreading are within the basin and are not directly related to the formation of either the Carnegie or Cocos ridges.Inaddition,the area can be divided into three regions of markedly different magneticcharacter;an area of large amplitude magnetic anom- alies roughly defined by the spreadingcenters,Cocos Ridge and the Gala- pagos Islandsplatform;an area including Carnegie Ridge, eastern half of the PanamaBasin,and northwest of Cocos Ridge which has usual mag- nticamplitudes;and a quiet zone over the northern extension of the Peru- Chile Trench. Magnetic data from eight crossings of the Middle Americas Trench between 10°N and 19°N and three traverses of the East Pacific Rise be- tween 13°N and 19°N are being used, together with gravity and bathymetric data, to determine the regional crustal and subcrustal structures.Pre- liminary results indicate an assymetry of spreading rates across the East Pacific Rise and detailed magnetization parameters are currently being calculated. 37

Seismic Profiling- Banks, Couch, Gemperle, Heinrichs,Johnson, MacFarlane Continuous seismic profiling along approximately 1500 km of track- line off southeast Alaska shows a synclinal structure between the coast- line and shelf edge north of Cross Sound.The upper synclinal deposits, of Plio-Pleistocene age, appear to be ponded behing a tectonic dam-like basement strucutre.South of Cross Sound the sedimentary structures near shore dip steeply towards the ocean.Near the outer edge of the shelf the rock layers are deformed by both faulting and folding.These deposits extend from the late Mesozoic into the early Tertiary.The change in character of the continental shelf off Cross Sound is probably related to the passage of the Fairweather Fault from the continent to the sea in this region.

Reflection profiles in Chatham Strait show scarp-like walls, a relatively small amount of sediment which shows extensive faulting to the surface and extensively faulted basement rock.It is suggested that either this strait has not experienced severe glaciation or that extensive tectonism has occurred since withdrawal of the ice. Reflection profiling over Paul Revere Ridge off northern Vancouver Island shows the ridge to be a large fault block approximately 2 km high and 115 km long.The ridge is thought to have been formerly a part of the continental shelf or slope off Vancouver Island which is now separated from the island by the Scott Islands Fracture Zone.Two prominent uncon- formities are apparent in the structure.The uppermost unconformity is postulated to be of Pliocene age and contemporary with the formation of Explorer Ridge.The next deeper unconformity may be of Miocene age and contemporary with changes in motion of Juan de Fuca Ridge.

Direct Interpretation of Potential Field Data- Bodvarrson, Adotevi-Akue

Methods that have been developed during previous years are now being applied to gravity problems in Oregon. New methods based on the Snow-Bateman technique for integral equations is being developed and will be applied to the inversion of gravity data from Oregon.

CHEMICAL OCEANOGRAPHY

Seasonal Distribution of Nutrients off the Coast of Oregon, 1968 -Ball, Park Mr. Ball completed his Masters Thesis March 16, 1970.The abstract follows: Phosphate, silicate and nitrate concentrations in the sea off the coast of Oregon were determined to study their seasonal distribution patterns.The water samples were collected monthly along the east west hydrographic line off Newport, Oregon, from the shore to165 miles (310 km) offshore.The samples were analyzed by both a Tech- niconAutoanalyzeiand by manual methods. Phosphate in January was greater than 0. 5µM at the surface, increasing to a 3. 3 µM maximum at 1000 m'throughout the year.With the onset of photosynthetic activity, there was a general decrease in surface concentrations.Concentrations decrease to less than 0. 1 µM in October with surface concentrations increasing in November and December, reaching a maximum in January. Silicate concentration was approximately 170 µM at 2600 m during the entire year.In January, surface silicate increased from less than 5 µM offshore to 13 µM nearshore; a weak silicate minimum was observed at a depth of 60 m offshore and at 5 m nearthe coast.In March nearshore surface concentrations were greater than 15 µM due to increased coastal river runoff;the silicate concentrations of Ore- gon coastal rivers were 150-250 µM.In July, a pronounced minimum occurred at 40-50 m depth, where the concentration was less than 2µM. Summer surface concentrations were less than 2 µM offshore, increas- ing to 40 µM nearshore as a result of coastal upwelling.Surface con- centrations in October were generally less than 5 µM along the New- port hydrographic line with increased nearshore concentrations due to river runoff. The nitrate maximum of 40-50 µM existed at 1000- 1200 m.In January surface concentrations ranged from 3 µM offshore to6 µM nearshore. March values were lower, ranging from 1 µM offshore to 5 µM nearshore at NH-3 (6 km).In July patches of nitrate-free water were observed at 40-50 m depth offshore, disappearing at25 miles (46 km) off the coast, at station NH-25, as a result of the influence 40 of upwelled and nitrate containing water.Late in October, nitrate con- centrations were higher, 5-6 µM, near the coast, and dropped to less than 0. 1 µM offshore.Patches of nitrate-free water were found from May to November. The existence of nitrate-free water near the surface indicated that the feature was formed by the photosynthetic activities of phyto- plankton.The formation of the silicate minimum and oxygen maximum below or near the bottom of the Columbia River Plume during summer months indicated intense photosynthetic activity. Neither preformed phosphate nor preformed nitrate changed with depth below the layers of active photosynthetic processes.Pre- formed phosphate was generally 1. 0-1. 2 µM below 200 m with varia- tion occurring in surface waters.For surface values,1. 2 µM, the highest of the year, was observed in July in upwelled water; 0. 4 µM, the lowest, also occurred in July within the influence of the Columbia River Plume. The vertical distribution of preformed nitrate seemed to be ran- dom and may have reflected analytical techniques.The range was be- tween 5 and 10 µM with a maximum at 12 µM.The 5 µM values were found at approximately 200 m with a maximum observed at 1000 m deep. The highest surface values of preformed nitrate, 2. 0 - 5. 0 µM, were observed in Januaryand t'Aelowest, 1.0 - 1. 5 µM, in July.March and Octobervalues werebetween the aboveextremes(1. 1- 2.0 µM).

Chemical Features of the Subarctic Boundary - Alvarez, Park, Gordon, Hager Mr. Alvarez expects to complete his Masters Thesis on May 4, 1970.The title of his thesis is "Chemico-Oceanographical Parameters of the Central North Pacific Ocean" and the abstract follows:

Data from theSURVEYOR1968 Spring cruise were used to study the vertical distribution ofsalinity, temperature,dissolved oxygen, appar- ent oxygenutilization,pH,alkalinity,specific alkalinity and percent saturation of calcite in twosections,one along162° Wfrom 350N to 450N and the other along1800Wfrom350N to 500N.Datafrom this cruise and additional data fromthe SURVEYOR 1968Fall cruise, YALOC66 cruise(summer)(Barstow et al.,1968)and BOREAS cruise (winter, 1966)(SIOreports, 1966)were used to study the distribution 41 of salinity, temperature, apparent oxygen utilization, preformed phos- phate and depth on the sigma-t surfaces of 26. 8 and 27. 3 in an area between 35°N and 52°N and 162°W and 155°E. In both sections the vertical distribution of the physico-chemical parameters is such that in general there is a tendency for the isograms to slope upward from south to north following the same trend of the sigma-t surfaces.This indicates that mixing and advection along the sigma-t surfaces play an important role on the distribution of these parameters.

AOU data from YALOC66 cruise(summer)compared to that from SURVEYOR1968 Spring cruise suggest that aeration by mixing, eddy diffusivityand conductivity takes place to more than 500 meters depth atabout 50°N.It also suggests that the changes of organic pri- mary production at the euphotic zone during different seasons of the year mayaffect to a great extentthe AOUdistribution on the 26. 8 sigma-t surface and to a very small extent onthe 27.3 sigma-t sur- face.

The direction of the flow suggested by the AOU distribution on the 26. 8 and 27.3 sigma-t surfaces was compared to that indicated by the acceleration potential contours on the St = 125cl/ton and 5t =80 cl/ ton surfaces drawn by Reid (1965).The disagreements were explained in terms of mixing and possible gradients of primary production at the sea surface.On the 26. 8 sigma-t surface a southward flow connecting the westward flow south of the Aleutian chain and the eastward flow farther south, between 175° E and 180° W is suggested by AOU distri- bution but not by the acceleration potential contours.If the circulation pattern at this density surface is similar to that at the sea surface, this linkage is very likely to be real.

The following paper, co-authored by Timothy R. Parsons of Fish- eries Research Board of Canada, Nanaimo, B. C.,Canada, has been accepted for presentation at the 15th General Assembly of the International Association for the Physical Sciences of the Ocean in Tokyo in September 1970. The title of the paper is "Seawater Carbon-Dioxide Partial Pressure and Hydrogen-Ion Concentration:Surface Distribution".The abstract follows: . Continuous, surface measurement of pH in the Pacific Ocean, from Esquimalt, Canada to Tokyo, Japan shows a complex distribution in the pH range of 8. 1 to 8. 3.There is an inverse correlation between pH and the partial pressure of CO?,and a positive correlation between 42 pH and temperature of seawater.In general, high pH associates with the photosynthetic activities of phytoplankton, and the low pH is observ- ed where deep water that has low pH mixes with the surface water. Some preliminary results of Mr. Gordon's thesis based upon data taken from US C & GSS SURVEYOR in the fall of 1968 have been accepted for presentation at the 1970 Annual Meeting of the American Geophysical Union.The paper is co-authored by John J. Kelley and Donald W. Hood of the University of Alaska, and P. Kilho Park.The title and abstract of the paper follow: Carbon Dioxide in the Surface Waters of the Bering Sea and Northwest Pacific Oceans, Late Summer

Surface contours are shown for carbon dioxide pressures, CO2, observed in waters of the Bering Sea and northwest Pacific Ocean.The data (given in ppm-atm.) were obtained from late August to mid-Oct- ober, 1968, aboard the ESSA-USC & GS Ships OCEANOGRAPHER and SURVEYOR. In the Bering Sea low values ofCO2,less than 200, were observed along a line from St. Lawrence Island to Adak and Nome and St. Lawrence Island.Along a line from Nome to Dutch Harbor the PCO2 ranged from around 300 in the north to more than 350 in the south. Very high PCO2 values up to 480 were observed in the vicinity of the Aleutians.The atmospheric partial pressure of CO2 was 311-312 ppm-atm. at this time.In the northwest Pacific a low PCO2 band of 260 lay in a generally east-west direction in the 155° E to 180° region studied.It was centered at latitude 40-42°N.The 275 contour lay a- long or somewhat to the north of the Polar Front.The low surface PCO2 values were the result of rapid carbon dioxide fixation by phyto- plankton during the summer compared to the lower rates of resupply from deep waters and from the atmosphere. The higher levels of PCO2 in the southeast Bering Sea may reflect vertical mixing or upwelling effects along and between the Aleutian Islands.

Coastal Oceanography - Gordon, Park, Alvarez-Borrego, Ball, Barstow, Gates, Roelofs, Tomlinson All of the 1969 Coastal Oceanography cruises were completed and have provided a great deal of chemical data.These data are now being analyzed and processed for publication in continued collaboration with the biologically and physically oriented members of COOC (Coastal Oceano- graphy group).See page 1. 43 Air-Sea Exchange of Gases in Coastal Waters - Gordon, Park PCOZ and dissolved oxygen data have now been obtained on cruises in June, August, October and January at depths from the surface to 55 meters.One interesting finding is a preliminary indication as to the time scale of oxidation of organic matter in and near the bottom sediments.It appears that a very large fraction of the organic matter fixed during spring and summer which settles to the bottom has been oxidized by late October. This is somewhat more rapid than we expected.This preliminary result is being investigated more fully in the data which remains to be analyzed and the whole body of data is being prepared for publication. Additional cruises are being planned for early May and late June to round out an annual cycle of observations.

K-Ar Dating of Deep-Sea Rocks - Dymond Completion of a rare-gas mass spectrometer has been accomplish- ed and the system has been fully operative for the past six months. A systematic appraisal of the quantity of excess argon in deep-sea rocks was one of the first studies undertaken.Results indicate that the glassy margins of all pillow basalts studied contain excess radiogenic argon. Profiles of Ar: K ratio as a function of depth in the basalt show that excess argon decreases rapidly with depth in the pillow and at distances 6 - 10 cm from the margin no excess argon is present.These results suggest that K-Ar dating of deep- sea basalts can be accurate if samples are chos- en from the holocrystalline interiors of basalt pillows. A submarine basalt boulder from the mid-Atlantic Ridge was re- covered during a cruise by van Andel, Heath, and Moore.This specimen was unique because it contained a baked calcareous ooze embedded in the glassy margin.Foraminifera from this ooze suggest an age very near the Pliocene- Pleistocene boundary.The importance of this faunal bound- ary prompted a K-Ar age measurement. The preliminary results of this analysis place the age of the basalt at 1. 8 million years.

Submarine Weathering of Volcanic Materials - Dymond K-Ar ages and Oxygen isotopic measurements (by G. D. Gerlick, Humboldt State) were made on glass shards recovered from deep-sea cores.The 6 018 content of the shards was found to increase with age 44 of the glass and indicated that the oxygen in shards of 50 million years age was approximately 50% exchanged.Oxygen isotopic exchanged was also observed with the weathering of submarine basalts.The amount of dO18 shift is correlated with the water content of the rock. A study of the chemical charges which take place with weathering of submarine basalts has been initiated.Using water content as an index of the degree of weathering, marked changes in both water and some ele- ments can be observed on the insides and margins of submarine rocks. Potassium is one of the elements most dramatically changed by weather- ing.It has been observed that a change in water content from 0. 5% to 1. 0% results in a factor of 3 increase in potassium.

Rare Gases in Submarine Basalts- Dymond The existance of excess radiogenic argon in submarine basalts is probably the result of trapping of mantle argon due to the rapid cooling under pressure.This implies that the composition of other rare gases in these rocks will also reflect to some extent the gas composition of the upper mantle.Analysis of the rare gases He, Ne, Kr, and Xe have been made on some of the same rocks which contain excess argon.Excess helium as well as Xe anomalies are present in these samples. 45

RADIOECOLOGY

Radioanalysis Procedures - Larsen Radioactivity of samples collected from the marine environment is measured by gamma-ray spectrometry.Three 12. 7 x 12. 7 cm NaI(Tl) well-type crystals each coupled to 512-channel analyzers are used in deter- mining the presence of gamma ray emitting radionuclides and their res- pective amounts.Data are reduced either by comparison of sample photo- peaks to known standards or by a non-linear least squares computer pro- gram for more complicated spectra.Environmental samples are generally counted for either 100 or 400 minutes. Background count rates are sub- tracted and the net counting information is stored on a Tally Paper Punch Tape system, an IBM typewriter digital output, and an X-Y plot.

Determination of65Znspecific activity in various tissues of the mussel, Mytilus californianus- Larsen Zinc-65 specific activity of various tissures in the mussel Mytilus californianus has been determined. Zinc-65 was measured by gamma-ray spectrometry and stable zinc was measured by neutron activation analysis. Specific activities of different tissues did not vary beyond the analytical error terms at each location.Marked decreases with distance from the Columbia River mouth were noted.

Columbia River Estuary Fishes- Renfro, Farrow Collection of environmental parameters such as temperature, sal- inity, nutrient concentration, dissolved oxygen and radioactivity at several stations has continued. As the result of reductions in the numbers of plu- tonium production reactors at Hanford, Washington, the levels of radio- nuclides in the Columbia River Estuary have diminished.Nevertheless, the radioactivity of 65Zn and other radioactive isotopes can be measured in water, sediment, plants, and animals of the ecosystem.This unique tracer-labelled system provides the opportunity to better understand the cycling of trace metals.

Radionuclide Transfer through Food Webs- Renfro, Farrow Radioecological studies of several neutron-induced radionuclides in 46 a small estuarine ecosystem have been in progress since 1966.Measure- ments of the concentrations of stable, as well as radioactive isotopes, per- mits the computation of specific activity, i. e.,activity of the radionuclide per gram of total element.This measurement provides an insight into the turnover rates of elements for organisms in different trophic levels. In a previous inventory of radionuclides associated with various com- ponents of the study area, there appeared to be higher levels of 51Cr by reducing hexavalent 51Cr to the trivalent state.The following experiment was performed:(a) Fresh intertidal plants were chopped into small pieces and placed in bags of nylon mesh. (b)The plant-filled bags were anchored to the bottom and allowed to decay.(c) Material from the bags was radio- analyzed montly for 65Zn and 51Cr.During seven months from Septem- ber 1969 to March 1970 the activity of 65Zn in the detritus remained near- ly constant.Because the levels of 51Cr in the detritus did not increase during this time, the hypothesis is rejected.

Non-biological Uptake of Zinc-65 From a Marine Algal Nutrient Medium- Renfro, Forster, Tomlinson In both natural and artificial aqueous environments, trace elements such as zinc may be taken up by marine algae in excess of their metabolic needs. Some authors have attributed such high zinc concentration factors to algal cell surface adsorption.Zinc adsorption in laboratory cultures is not restricted to tissue surfaces alone.Precipitates may develop in nutrient media from which chelating agents have been eliminated.These precipitates and the laboratory glassware may effectively adsorb zinc. Such non-biological uptake may cause serious errors in uptake studies, de- pending on the methods used.For this reason, non-biological adsorption of zinc in a laboratory system for algal zinc uptake studies was determined using carrier-free 65Zn tracer. The results of these studies were as follows: 1. A nutrient medium precipitate formed at a pH of 7. 5 + 0. 1,contain- ing P04 - P as the prevalent chemical species.Calcium and magnes- ium were also found to be major constituents. 2. Zinc adsorption by the precipitate in the pH range, 6. 3 + 0. 1 to 6. 7 + 0. 1, amounted to less than 10 percent of the total 65Zn added.This value increased to 25 percent at a pH value of 7. 1 + 0. 1, and to 70 per- cent at pH = 7. 5 + 0. 1. 3. Zinc uptake by Pyrex was measured at a pH of 8. 0 + 0. 1.Uptake equilibrium was found to be complete after one hour of exposure to the radioactive medium. 47

4.Zinc adsorption by Pyrex was found to negligible below a pH value of 6.5. Above this pH, the adsorption increased ten to one hundred times within two pH units. 5. Pretreatment of glass surfaces with a commercially produced chemical which causes hyrophobic effects reduced zinc adsorption by about 80 percent. 6. For the conditions used (12.4 ppb total zinc, pH _ 8.0 + 0. 1), zinc ad- sorption by pipettes of the size range, 2 ml to 20 ml, amounted to 7- 11 percent of the zinc in the contained sample. 7. The relationship, percent sample adsorption vs. glass surface area/ sample volume was found to be linear through the origin.One impli- cation of this finding was that adsorption of zinc at seawater concentra- tions could be higher than 11 percent of the contained sample for pi- pettes smaller than 1 ml. For pieces of laboratory glassware having relatively low surface area to volume ratios, zinc adsorption at these concentrations may be considered negligible.

Radioanalysis of Hake, Merluccius productus-Pearcy, Cutshall, Naidu

Samples ofhake,caught off the western coast of the U. S. during the summer of 1969,wereradioanalyzed.A total of 81fish,ranging from 300-550 mm in length and collected at latitudes from 37°N to 46°N,' have been analyzed. Radioactive zinc content was essentially zero in samples between lat- itude 37°N and 39°N but increased steadily northward from 40°N (6 pCi/ g ash) to 46°N (30 pCi/g ash).This is in keeping with the concept that the Columbia River is the source of 65Zn.Cesium-137, in contrast, did not vary much with latitude (0. 5 to 1. 0 pCi/ g ash), a result to be expected from its fallout origin.Additional samples, collected off Oregon and from Puget Sound are now being processed.In addition, stable zinc measure- ments on each of the above samples is underway.

Specifically Sorbed Radionuclides - Cutshall, Evans, Johnson Efforts to further characterize sorption processes on Columbia River sediment are being continued.Availability of 65Zn,6oCo and 54Mn to various leaching solutions, particularly solutions of divalent transition metals, is being measured.Relative effectiveness as displacing ions dew creases in the order:Cu++, Zn++, Co++, Ni++ Mn++. Ease of displace- ment of radionuclides increases in the order:45Zn, 60Co, 54Mn. 48 Specific activity of radionuclides displaced in these experiments is also being measured.Hypothetically, the same reservoir of adsorbed radionuclide is capable of reaction with various transition metal solutions. Thus the specific activity available to each solution should be constant for a given sample.Preliminary results appear to confirm this suggestion. In addition repetitive equilibrations of sedimentswiththe leaching solutions are under way in order to estimate the total reactive reservoirs of adsorbed radionuclides.

Zinc-65 in Continental Shelf Sediments-- Cutshall, Renfro,Johnson The reservoir of Pacific Ocean 65Zn is about 3-6 kilocuries. Since 75-80% of this 65Zn enters the Pacific in a form bound to particles and apparently little desorption by seawater occurs, sediments on the con- tinental shelf off Oregon and Washington should contain several kilocuries. We have examined shelf sediment from the upper 1 cm between Newport and the Strait of Juan de Fuca for 65Zn.Only about 100 curies can be accounted for at present. We are also examining cores to see if signifi- cant quantities of 65Zn are buried deeper than 1 cm.It appears likely that much of the 65Zn has been dispersed beyond the shelf.

Seawater-Riverwater Mixing Experiments- Cutshall, Evans,Johnson There is evidence that trace elements adsorbed on riverborne sus- pended matter is made partly soluble upon contact with seawater.On the other hand there is also evidence that soluble trace elements in river water are rapidly precipitated upon entering the sea.In order to directly evaluate the net effect of these opposing reactions we are mixing river and seawater and observing changes in filterable and "soluble" radionu - clides.Similar observations are made concurrently in Columbia River estuary samples over a wide salinity range.The data will be part of Mr. Evans' thesis.

Ultraviolet Irradiation of Sediments - Renfro, Cutshall, Lenears Columbia River sediment suspensions are being subjected to ir- radiation with ultraviolet light in an effort to destroy organic matter.Pre- 49 liminary experiments are designed to determine:(1) effectiveness of UV light in oxidizing sediment sorbed organics and(2) release of sorbed radio- nuclides by irradiation.Hopefully these experiments will be helpful in estimating the role of organic matter in retention of radionuclides by Col- umbia River sediment.This work will be a part of Mr. Lenear's thesis research.

Mercury - 203 Study - Cutshall, Renfro Based on nuclear properties we suspect that 47-day203Hgis among the suite of neutron-induced radionuclides in the Columbia River.If present in sufficient quantity this nuclide may be useful in studies of the environmental cycling of mercury.Interference from other nuclides pre- vents detection of 203Hg directly.Positive identification of203Hg inone sample has been confirmed by chemical behavior, gamma-ray energy and half-life.Levels are too low for use in extensive tracing studies.

Particulate-ionic Ratios of Manganeseand Copperin theVicinityof Kraft MillEffluentsin the Columbia River at Camas,Washington - Forster, Cutshall, Hennebry, Schmidt(Radiation Center) Of particular interest to the ecologist is the acquisition of knowledge of existing reservoirs of a variety of biologically active trace metals in aquatic environments. How these metals interact with waste chemicals from industrial and domestic sources, how their physical-chemical forms are altered and in what forms they are subsequently incorporated into or- ganisms is becoming increasingly important in evaluating the ecological hazards of inputs of such metals into man-associated environments.The objective of this study was to examine the dynamics of adjustments in par- ticulate-ionic ratios of several biologically active metals placed into the Columbia River with spent sulfite liquors and associated kraft mill wastes. Assuming a dynamic equilibrium initially exists between particulate and ionic states of naturally dissolved metallic elements in river water, such as manganese and copper, adjustments in particulate-ionic ratios of these same elements entering the Columbia River with kraft mill wastes from the Crown Zellerbach facility at Camas, Washington were observed at selected cites downstream from two outfalls during high and low water conditions.Neutron Activation Analysis was the principal tool used in determining abundances of the elemental fractions.The results are pend- ing completion of data analysis. 50

Uptake,Retention and Concentration of Phosphorus-32 in Juvenile Starry Flounder- Forster, Renfro, Bolen, Lyford The objectives of this study are to determine:(1) the seasonal con- centrations and fluctuations of phosphorus-32 in starry flounder and their immediate environment (water, prey organisms, etc) in Alder Slough, a small water body connected to the Columbia River Estuary;(2) the ani- mal's turnover rate of phosphorus-32; and (3) the importance of food, water and sediment in contributing to the young flounder's body burden of this radionuclide.

Juvenile starryflounder,amphipods and water from Alder Slough have been monitored since the summerof 1969.Maximum specific activ- ities of26,38, and60 nCi32P/m P were observed inAugust,1969.Min- imum values of 0.4 and 20nCi2P/gmP occurred in starry flounder and amphipods inJanuary, 1970.The water specific activity was 175 nCi32P/ gm P during this period. Retention experiments during the summer of 1969 in which starry flounder from the Columbia River Estuary were transferred to a cage in the Yaquina River were unsuccessful because of large variations in phos- phorus-32 concentration among individual animals. An uptake experiment in late fall, 1969 in which non-radioactive animals were transferred to a cage in Alder Slough showed less individual variation.However, radio- phosphorus uptake during this period was slow, indicating little turnover. Additional experiments of this nature are presently in progress.

A small aquarium system has been constructed at Hammond, Ore- gon to determine the routes of phosphorus-32 uptake by the starry flounder. Fish will be exposed to different combinations of radioactive and non-radio- active water, food and sediment in order to determine the relative impor- tance of each media in contributing to the flounder's body burden.

Trace Element Analysis of Estuarine Water - Forster, Cutshall, Wagner

Monthly analysisof trace elements in Columbia River Estuary samples is beingcontinued.Trace elements are concentrated prior to measurementby two chelation-extraction methods.Chelatingagents used are ammoniumpyrrolidine dithiocarbonate and sodium diethyldithiocarbon- ate and the solvent is methyl isobutyl ketone.Zinc and manganese are the principal elements of interest. In addition, monthly analysis of sodium, potassium, magnesium and calcium at our Harrington Point station was begun in January, 1970. Each of these elements is measured directly using atomic absorption spec trophotometry. 51

BIOLOGICAL OCEANOGRAPHY

Assimilation of Organic Matter by Marine Second Trophic Level Grazers - Small, O'Connors, Pequegnat, Menzies Work was begun on determination of "feeding niches" for neritic microcrustaceans to test the hypothesis that competitive advantage can accrue to the species optimizing its "feeding niche".Phytoplankton to be used as food in this study were isolated in culture, and culturing techniques peculiar to these organisms were determined.Crustacean collections were begun, and preliminary work was started on measuring the food assimilation fraction.Assimilation efficiency of total organic matter, organic carbon, organic nitrogen, 14C, protein, and lipid will be investi- gated for organisms grazing on different types, sizes, and concentrations of food, and the hypothesis of competitive advantage will be tested by ap- propriate statistical means.

Phytoplankton-ZooplanktonRelationships in Different Hydrographic Regimes- Small, Pequegnat,Ramberg, Vogel

A cruise of theR/ V YAQUINAoff Oregon during June and July of 1968 provided data for a first study of the relationships of hydrographic and chemical parameters to estimates of biologicalactivity.The emphasis was on carbon and nitrogenreservoirs.Phytoplanktonpigments,nitro- gen and carbon-nitrogen(C/N) ratiowere used along with apparent oxygen utilization(AOU) andthe nitrate content of the water to estimate the distri- bution of phytoplanktonproduction.Sigma-t. AOU,and nitrate were used to definethe hydrographicand chemicalconditions.The work culminated in an MS Thesisby Mr.Ramberg and subsequent reporting of results at an international meeting in December, 1969. Upwelling was the major source of nitrate for the surface waters, and consequently, phytoplankton production was most intense where up- welling was active.The Columbia River plume appeared to support a sizeable amount of phytoplankton production just south of the river mouth. Particulate nitrogen increased and particulate nitrogen increased and par- ticulate C/N ratio decreased as the water became more biologically prod- uctive.Chlorophyll, particulate nitrogen, and C/N ratio showed the effects of upwelling and the Columbia River plume on biological production. A subsurface negative AOU core was clearly defined in areal extent and in- tensity.Its occurrence was explained by inshore phytoplankton production, 52 oxygen exchange with the atmosphere, and possible in situ phytoplankton production.Further samples taken in thesame regionsin 1969 have not been fully analyzed. In addition to the phytoplankton and particle properties, the organic content of grazing zooplankton is being examined for possible relationships to hydrographic regimes. Trace elements in phytoplankton and particles are being investigated in relation to different hydrographic regimes.With respect to field col- lections, data were collected on two one-week cruises, one in January and one in March, and on several one-day trips to the Columbia River Estuary and the nearshore waters off Newport.In the laboratory, neces- sary testing of methods and materials is nearly completed (only one test remains to be done).Also, one complete run on the atomic absorption spectrometer of samples collected last summer and fall was made, and the results are being analyzed.The preliminary findings tend to lend strength to the hypothesis that hydrographic regimes affect phytoplankton trace metal composition; however, these are preliminary findings only.

Photoperiodism in Phytoplankton Carbon Assimilation - Small, Donaghay The chemostat developed for determination of photoperiodic effects on phytoplankton carbon assimilation has been stabilized to maintain Skeletonema costatum in log growth at constant total carbon levels for seven days.The results of a five day experiment under a light-dark re- gime of 8: 16 hours with measurements at two hour intervals for carbon, nitrogen, chlorophyll "a", and 14C uptake, are under analysis.Other light-dark photoperiods will be investigated.

Marine Microbiology -Morita,Steenbergen, Wright, Ishida, Aston, Buck, Burnison, Gillespie, Griffith, Jones, Hanus, Paul, Staley, Yusha. Continued research is in progress on salinity effects on changes in metabolic pathway, salinity-temperature effects on the induction of glutamic dehydrogenase formation, characterization of malic dehyrogenase, and aldolase.Research has begun on the effects of temperature, salinity, and pressure on the formation of various RNAs as well as on the activity of the amino acyl tRNA synthetases.Kinetic studies on the uptake of var- ious substrates by Vibrio marinus and other psychrophiles under vary- ing salinities, pressure and temperature has also been initiated.Research on the question as to "why" microorganisms originally isolated from near surface waters expire when pressure is elevated is also being initiated. 53 Eutrophication studies on Upper Klarnath Lake indicate that the vitamin B12 is not limiting for the growth of algae, or other microorgan- isms. Many of the bacteria isolated from thelake produce B12 as well as most of the bacteria that are associated with the Aphanizomenon flos- aquae. Degradation of B12 also occurs.Soluble phosphate was shown to occur during cryptic growth of bacteria and approximately 20% of the bacterial isolates from Klamath Lake had the ability to solubilize CaHPO4. The amino acid flux of the lake as well as uptake and respiration studies of various organic substrates are also being investigated.

Remote Sensing Oceanography - Pearcy, Keene, Mueller, Smith High-altitude color photography (60, 000 ft) of the Oregon coastal region taken onJuly 1969during a period of intenseupwelling,revealed several very unusualfeatures.Extensive wave-like patterns along the coast were especially prominent near the southern border of the Columbia Riverplume.Their cause isunknown.Numerous color fronts were evi- dent,primarily along the coast and river outflows but one front extended westward for 30miles.Densitometry measurements indicated that up- welling,the Columbia River plume, and the offshore oceanic waters all influenced water color.High-altitude color photography of this type has potential for studying large-scale phenomena and providing a nearly synop- tic picture of the sea surface.

We are also continuinganalysis of the data obtained by the multi- spectral scanner on the University of Michigan's aircraft.Film strip imagery has been obtained for areas where thermal or color fronts were noted.Sharp thermal and/or color changes are sometimes obvious in re- gions of upwelling and the Columbia River plume. See also page 1.

Early Life History of Boreal Fishes and Shellfishes- Pearcy, McNeil, Satterlee, Zimmerman,Spring

A total of 159 tows using Bongo and Clarke-Bumpus nets have been made between 1 October 1969 and 1 April 1970 in Yaqiuna Bay and coastal waters off Newport.To date over 600 samples have been sorted.Fish eggs or larvae were present in over one-half of these samples.Sixteen families and 14 species of fishes have been identified to date. 54 Feeding Habits of Lanternfishes - Pearcy, Tyler Euphausiids, mainly E. pacifica, comprised the bulk of identifiable food in three common lanternfishes collected off Oregon, Stenobrachius leucopsarus, Diaphus theta, and Tarletonbeania crenularis.Copepods (Calanus spp. and Metridia lucens) were numerically most abundant. No large differences were associated with size of individuals with- in the three species of fishes.Changes in stomach fullness and state of digestion suggested that these lanternfishes fed mainly at night.

Zinc Radioecology of Benthic Fish - Pearcy, Vanderploeg This study examines the zinc-65 radioecology of benthic fishes caught off Oregon.Our purpose is to elucidate differences in specific activity among the species caught at a single depth as they relate to sea- son, distance south of the Columbia River and the ecology of species. For each sample, the amount of65Znand total Zn are determined by gamma-ray and atomic absorbtion spectrometry. From these values specific activity is calculated. A model that expresses the relationship between specific activity of a fish and its prey was derived.This model suggests that size may significantly effect specific activity. A preliminary analysis of the data supports this hypothesis.In addition, this model will allow calculation of zinc uptake rates for different species.Therefore, special effort is being extended to obtain the prey of fishes for radioanalysis.

Scattering Layers and Vertical Distribution of Oceanic Animals - Pearcy, Mesecar, Kalk Our conducting cable with a six-foot Isaacs-Kidd midwater trawl and an eight bar Multiple Plankton Sampler was used successfully on a cruise in November to sample discrete depths.Depth, temperature, flow- meter revolutions, and net actuation were monitored with this system. A variable complex of organisms, includingmesopelagic fishes, euphausiids and sergestidswerecommon in12 and 38.5 KHzscattering 55 layers.Variability was large among nets fished horizontally within one depth or vertically among depths.

Swimbladder Morphology and the Buoyancy of Myctophids - Pearcy, Butler Because of their gas-filled swimbladders, fishes are suspected as a cause of sound scattering layers in the ocean. Two species of mycto- phids off Oregon have been reported as having fat-invested swimbladders. The presence of gas-filled swimbladders in common species off Oregon is being studied.Lipid extractions show that high lipid content is an alter- nate buoyancy mechanism for those fish without a gas-filled swimbladder. Dissections of fresh specimens at sea have shown the presence of gas-fill- ed swimbladders in some juvenile myctophids.Histological sections are being made to enable comparisons of swimbladders,

Yaquina Bay Plankton Studies- Frolander, Flynn, Zimmerman,Theurer Zooplankton samples have been collected weekly at five stations in the bay with Clarke-Bumpus and Bongo Samplers (see Pearcy et al.,"Early Life of Boreal Fishes, " for concurrent studies utilizing the data).At each station surface and bottom water samples were collected for deter- mining temperature, salinity, and dissolved oxygen content.

Netarts Bay Plankton Studies - Frolander, Zimmerman Weekly zooplankton samples have been collected in Netarts Bay since October, 1969.Data on water temperature and salinity are taken simultaneously with the tows and daily records of atmospheric temperature and precipitation are maintained in order to investigate two probelms. First, analysis of plankton samples should allow determination of numbers and seasonal succession within the plankton community.These data will he used to determine availability of food for young salmon being released from the Whiskey Creek hatchery.Second, comparison with zooplankton samples collected during the same interval from Yaquina Bay should lead to conclusions concerning diversity and timing of succession in the two dissimilar marine environments.

Marine Ecological Studies at Palmer Station and Vicinity - Stout, Shabica During the 1970 summer season a study transect was laid out near 56 Palmer Station, comprising 28 stations from high tide level to 16 meters. At 13 stations experimental plots of 1 m2 were cleared of plant and animal life, and the replacement and growth of organisms is being studied on these plots throughout the year.Three distinct subtidal regions can be recog- nized: (1) a gently sloping rocky substrate with increasing amounts of sediment with depth, characterized by the limpet Patinigera polaris, Hildenbrandia and other algae, and the sea urchin Sterechinus neumayeri; (2) a relatively flat mud bottom characterized by the bivalve Laternula elliptica, algae and occasional clumps of the nemertean Lineus corrugatus; and (3) a near vertical rock face, characterized by brachiopods and a sponge-tubicolous polychaete complex in the lower reaches and limpets in the upper reaches. Patinigera polaris occurs in concentrations of up to 123 per square meter from 1 to 3 meters below the low tide level, and less abundantly to 16 meters; the limit of diving observations. Approximately q00 specimens from various depths and habitats were collected, marked by attaching fish tags with polyester resin to the shells, and returned to obtain monthly in- formation regarding seasonal migration and the development of the algal belt, temperature tolerance, growth and metabolism, nature of food, fe- cundity and the effects of ice on their position in the intertidal. The large infaunal bivalve Laternula elliptica occurs in concentra- tions of up to 75 per square meter from 9 to 14 meters below the low tide level in semi-consolidated mud. The greatest densities were found in those areas having the least amount of surface cover.The sediment at the site contained foraminiferans, cumaceans, polychaetes, small bivalves, gastropods, ostracods, isopods, and amphipods. No commensals were found associated with the clam. The food. preferences of intertidal and subtidal pycnogonids were studied in laboratory aquaria.The animals were collected by bottom trawls from R/V HERO and by scuba diving.Austrodecus sp. and Pen- tanymphon antarcticum were found associated with sponge, Bryozoa and hydroids.Both species preferred hydroids to Bryozoa and sponge.Col- ossendeis robusta, C. australis and Ammonthea carolinensis, the three largest subtidal pycnogonids collected, were found associated with brachio- pods, tubicolous polychaetes and encrusting red algae.Colossendeis ro- busta was observed to feed in soft sediments and C. australis preferred tubicolous polychaetes.Hedgpeth (personal communication) had suggested that some large Colossendeids might be feeders upon meiobenthos in soft sediments.The food preference of Ammothea carolinensis was not deter- mined.The one specimen, an ovigerous male, was very sluggish and re- mained stationary with the proboscis resting in the mud.Colossendeis megalonyx. megalonyx, Decolopoda australis, Pallenopsis cf. patagonica 57 and Nymphon sp. were collected by trawling in the Port Lockroy area. Decolopoda and Pallenopsis were observed to feed in the soft sediments. C. megalonyx preferred tubicolous polychaetes and Nymphon sp. prefer- red hydroids.Several specimens of Achelia sp. were collected in the in- tertidal at Port Lockroy.All specimens were associated with hydroids and appeared to feed upon them. Approximately 4000 specimens of the small viviparous clam Lasaea consanguinea were collected in February and March from the intertidal region at Port Lockroy and transferred to the laboratory at Palmer Station where they are being maintained in aquaria for montly observations on various aspects of their reproductive biology. A study of the intertidal association was made.In the intertidal zone, L. consanguinea is confin- ed sharply to the mid-tide level within a very narrow vertical range.The clams were collected on rocks covered by hydroids and algae.Close ex- amination revealed that the byssal threads of the clams were not attached directly to the rocks but rather to the hydroids and algae.The entangled mass of byssal threads, hydroids and algae provides a habitat for numer- ous organisms, e. g. turbellarians, gastropods, polychaetes, amphipods, copepods, ostracods, nematodes and pycnogonids.Turbellarians and amphipods were the most conspicuous members of this association.Many of the clams had epizoic foiliculinids on them. From a total population of 895 clams collected in February, a sample of 76 was examined. Out of 76 clams examined, 39 bore young.The largest young measured while still in the parent ranged from 0. 15 to 0. 40 mm. Generally, it was found that the larger individuals tended to produce more young than smaller ones. No young were found in clams 2.5 mm in length or smaller.In addition, in the larger specimens, there were clams having no young; however, these clams may have been dead, since the valves were reflexed.The mean number of young brooded per specimen ranged from zero in the 0. 5 mm size class to 75. 2 in the 4. 9 mm size class.The greatest number of young brooded by a single adult was 132, in an individual in the 4. 9 mm size class.The size of the smallest individuals brooding young is not known, but no specimens examined in the 0. 5 or 1. 6 mm size class con- tained any young.The stomach contents of many specimens were examin- ed and consisted of detritus.

Albacore Oceanography - Pearcy, Panshin Initial analysis of the 1969 commercial albacore tuna catch records has emphasized the relationship between fish catches and sea-surface temperature because of the commonly accepted importance of temperature as the key determinant to abundance and distribution of albacore. Much analysis remains to be done.Further processing and analysis will examine correlations of fish catches with water color, mixed layer depth, and hour of the day.Distributions of catch per unit effort will be examined in detail as a function of temperature and of the temperature field.For the days on which remote-sensing flights took place over the fleet, microscale changes in catch per unit effort can be established.Fi- nally, stepwise mutliple regression will be used to seek out significant re- lationships between albacore catches and the various oceanographic vari- ables measured by research vessels. The clear conclusion to date is that temperature is a crucial factor in determining abundance and distribution of albacore tuna off Oregon, but that other significant factors are also operative concurrently.The goal of subsequent research, with special emphasis on mixed layer depth, is to establish what these other factors are in a quantitative sense. Quite possibly the most useful result of the 1969 project will be the more specific direction of investigative efforts for 1970 and subseq- uent years.See also page 1. 59
