Introduction

The following progress report presents a summary of the work conducted through January of 1973 as specified in our proposal, "The Development of Methods for Studying Physical and Biological Processes in the Nearshore Zone onthe Pacific Coast of the United States," supported by the Eugene Water and Electric Board, Portland General Electric Company and the Pacific Power and Light Company. Although we started this program in the early summer of 1978 without adequate lead time to order equipment and hire personnel we have been able to make a meaningfulstart at achieving the goal of developing study methods for the nearshore zone. However, the progress is spotty. In the areas of sampling fish and benthic organisms a limitation on boats available, equipment on hand, and number of personnel hired resulted in little effort being expended in this area. The studiesof surface currents and of phytoplanktonand zooplankton distribution have been initiated and significantprogress has been made. In these cases the studies have been adequate to enableus to do a more effective job of planningfor futureneeds in thesestudyareas. We anticipate having significant programs in all areas during the 1973 working season. The logistic problem was difficult during the first year's operation. We plan to reduce this problem greatly during 1973 by shiftingour opera- tions to Newport andbasing most of our personnel there for the summer. This will increase our efficiency by allowingus to utilize both the existing weather and the time of our personnel more effectively. We feel that in general the only way to develop adequate methods is to take a particular method, use it to gather data under field conditions, and evaluatethe adequacy of the method by a careful examination of the data collected. This approach is reflected in the following discussion of the individual subprojects. 2

Working Vessels

The experience that we had during the 1972 workingseason indicates that the Pacific City-style dory isa satisfactory vessel for working in this zone. It allows us to come through the surf and to the shore during many of the working days during the summer. It does not, however, allow us this ability on days when the swell is running high. It also is capable of handling the various types of sampling rigs thatwe need for this program. Although the dory itself is capable of doing the type of work that we desire, we find that the dory as equipped last summer did not give us as full and versatile a range of operation as we desire.In particular, we find two areas.in the dory operation that were less than completely satisfactory.The use of a conventional outboard engine, ina well, neces- sitates the use of an extra man for handling the doryas we are coming through the surf to the beach.This extra man is necessary to lift the motor to keep it from hitting on the sandas we are coming to the beach. This type of motor also leavesus without power when we are inside the surf zone and this requires extra manpower to hold the dory in place. The second area of deficiency was the lack of navigational equipment.This proved to be a safety problem on days whenwe were caught in a fog. We also find that we were unable to locate and replicatea station with any degree of accuracy without the help ofa triangulation from shore. To remedy this situation and to reduce theman power requirement imposed by such triangulationwe feel that a radar and fathometer system will aid us greatly in making the bestuse of the dory.We will also propose the use of a jet powered dory to increase the efficiency ofour operation. Although we did not haveany largeeffort directedtoward large animal sampling last summer, we did do enoughwork with the doryin the surf to determine that it would bepossible toset a beach seine with the dory and then move the doryout of theway and pull the beach seine from the shore. We will use thedory for this typeof operation during the coming summer. We will also usethe dory topull conventionalottertrawls and bottom sampling devices throughthe surfzone underfavorableconditions. 3

Phytoplankton

The data presented in AppendixI are representative of the phytoplankton data that were collected during the 1972 period. The procedure for the collection of these datais as follows: An NIO water sampling bottleis used for collection of one liter water samples. The use of this bottle allows sampling to occur at any depth from thesurface to the bottom within the nearshore zone. The bottle is an adaptionof the Nansen type reversing water sampler, which reverses and locks in place ata particular depth to take the desiredsample. The water sample so obtained is then processed in the followingway. The water from the NIObottle is placed ina one liter plastic bottle and the one liter plastic bottle is submerged in a water bathon the boat to maintain it at its correct temperature. The water bath is also designed to reproduce the approximate light intensity that the phytoplanktonwould be encountering at their depth of collection. This light intensity is reduced for lower samples by the successive additionof screens to the top of the water sampling container. The phytoplankton samplesare then trans- ferred to a shore-based station for filtering. Only six to eight samples are collected at one time before the trip to the shore-based facility. The samples typically spend about one hour between the timeof collection and the time of filtration. On the shore the water samples are processed ina tent, where we are able to filter them througha specially developed one liter filtering apparatus using a 0.8 micron filter. This filter willremove essentially all of the larger diatoms, which appear to makeup the majority of the plankton in this area. The filtering device isa pressure filter and in the work last summernitrogen gas was used to developthe pressure to push the liter of material through the filter. The filter, thus attained, is then frozen using dry ice in the field and retained inthis frozen condition until time for analysis.

The processing of the frozen filtersin the laboratory is started by grinding them in a mixer ina solution of 90% double distilled acetone. The solution is then placed ina refrigerated centrifuge and spun down for 20 minutes. During this processing,care is taken to keep the samples constantly refrigerated and in the dark. This is necessary since both 4

light and heat will tend to alter the pigments. The supernatant liquid is then read in a spectrophotoneter at six different wave lengths. This raw data is then analyzed by a computer program to determine the pigment values as presented in Appendix I. The program calculates chlorophyll values based on two different methods that have been used by other investi- gators. The values given in Appendix I after the analysis are values for the chlorophyll content of the particular sample. Although, the chlorophyll content is not a direct measure of primary production in a marine ecosystem, it is in fact, a measure of the potential production fora system and is widely used in this way. The advantage to using this type of measurement lies in the fact that one is able to get a great number of measurements in a relatively short period of time. If a person is measuring the actual production by the various light bottle-dark bottle techniques it will be much more difficult to obtain a survey of a broad areaover a short period of time, since each sample requires a considerable incubation time andre- quires a longer time for analysis than the samples measured in theway we are measuring.

Therefore, we propose to test the validity of this method asa survey method for primary production in a given region and to validate this method against measurements of primary productivity bya carbon-14 method during future years. The data that we have at this time illustratesome difficulties encountered with this type of measurement. The greatest difficulty at this stage is our inability to obtain replicate samples thatare showing a consistent value. At this time we blame this on the fact that we have not had enough development time to standardizeour methods to allow us to operate more accurately in this area. Therefore, a first effort in the future year's work will be to use this method and to develop greaterpre- cision in its use so that we can get the variations between replicate samples taken at the same time and the same place down toa much lower level.

Since we did not make measurements of productivity,we will plan to develop the techniques for making such measurements during thecoming work period. We will also develop counting abilities to determine population sizes for various major species during thisseason as well. 5

Zooplankton Sampling

The data collected during the past working yearon zooplankton are pre- sentedin Appendix II. All of these data were collected by the following method. A Clark-Bumpus zooplankton sampling device witha five inch diameter mouth and a number6 mesh net was used to collect allsamples. This sampler has a rotor on the front that allows water to turn the blades of a meter. This meter has been calibrated in a known environment (such as a swimmingpool) and with this calibration it allows calculation of the numberof cubic meters of water that flowed through your sampling device. Therefore, it is possible to count theanimals andknowing the number of cubic meters that have passed through the device, itis then possible to determinethe number of organisms in each cubic meter of water. A sample thus collected is diluted down to permit taking 3-4 aliquots which,whencombined, comprise a subsample containing 400-500 individuals. This definedsample is thencarefully counted and identified by species, sex, and stagein the life cycle. The raw data so collected are then processed bymeans of acomputer program to give the results as demonstrated in AppendixII. The use of this computer program saves a great deal of time in the calculationof densities of organisms in this nearshore zone. Our studiesfor the last summer have allowed us to develop thenecessary techniquesfor collecting and processing this type of data. We havelearned that the dory is in fact an excellent platform for the collection of zooplankton data. The dory used lastsummer waslimited in that it hadno power winchfor the precise and rapidlowering andrecovery of the zooplankton net. Future work in this area will be greatly facili- tated by the use of a dory that has thepower winch available for these studies.

Although this area of the coastal ecosystem has not beenpreviously studied orsampled, we have confirmed the species distribution with respect to time anddistanceto shore could have been predicted from previous studies bothwithin the Yaquina Bay and from farther offshore. The data indicatethe occurrence of sampling errors on the replicatesamples that are largerthan we arewilling to accept at this time. Therefore, it will 6

be necessary for us to devotea great deal of attention to methods of reducing error between replicate samoles and secondlyto providing reliable estimates of the amount oferror that is inherent in this sampling method. Only by having information that indicatesthe size of the expected error will we be able to set confidence limitson future samples that are associ- ated with a particular location.

One component of the observed variability isundoubtedly the result of patchiness in distribution of the organisms. Future efforts must include a sizable effort to determine the nature of such patchiness. Sampling methods must then be developed which willtake this patchiness into account and which will reduce the replicate sample variationdue to patchiness. This effort will have a high priority for the1973 working year. A summary of the data showed thatwe noted a total of 50 different species in the plankton samples during this study'speriod. The number of species and the species of maximum abundance variedboth with distance from shore and with the time of sampling. Dominant in this analysis were Acartia clausi, Acatia lo ngiremis, various speciesof Pseudocalanus, Podon leuckarti, and various barnacle life stages. Acartia clausi was most abundantnear shore and increased in numbers from July to mid-August and then decreasedto mid-September in our sampling. Acartia longiremis was most abundantfarther offshore with a rather sizable fluctuation in abundance during the time of thestudy. Pseudocalanus species were consistently ofa higher abundance near shore and relatively stable at all near shore stations witha slight decrease in August. Podon and the barnacle stages became abundant at erratic intervalsand especially abundant in September. They are found in all stations from Auguston and were in the largest numbers on the days of the roughestseas. Studies of zooplankton abundance with depth,indicated that we were finding a maximum in abundance and diversityof species about 15 meters in depth. Therefore, this depth was usedas a standard depth for towing our sampling device for the remainder of the sampling period. There is some variation with the abundance of individual specieswith depth. This variation which has been noted requires further evaluation. This type of 7

information will, of course, become extremely important in the planning for any possible cooling water intake in the marine environment. The specific design of such an intake should take into account the death distribution of all of the various nearshore marine species to trv to select an intake depth thatminimizesthe pumping of such organisms through the industrial operation of interest. The distribution of species and abundance of species in the direction parallelto the shore was noted. Since the meaning of this variation is as yetundetermined, it obviously must be studied in greater detail. This variationcould againbecome important in determining our location of cooling water intake designs. We will make additional studies to try to tie down the differences that have been noted. For example, the differences could be related to towing direction in terms of towing the sampling net or they might be due to varying sea conditions and the influence of the headlands on the organismin particular areas. Therefore, we will replicate our efforts and try to determine the importance of towing pattern and headlandsunder varying wind conditions with the relative abundance of samples attainedat different locations parallel to the beach. Additional efforts will be devoted to checking the inherent capabil- ities of the sampling instruments in producing accurate replicate samples as opposed to short term variations in the population which give the appearance of nonuniform sampling techniques. Several devices will be built and tested during thecoming summerto try to reduce the variationwe seein this type of program. A good deal of further effort is required along these lines to enable us toplan intelligently future sampling programs in this area. Certain other physical problems happened that reduced our sampling efficiency; for example, on four sampling dates we found a great deal of difficulty in obtaining reliable samples of zooplankton due to a clogging of the net with either phytoplankton or with jelly fish. As a result of these difficulties we plan to use a sampling screen which will run in front of the zooplankton sampler and allow us to screen out the jelly fish that were cloggingthe Clark-Bumpus net. The problem with phytoplankton is of coursenot so easily solved and it appears to be a problem we are forced to live with. 8

In conjunction with the zooplankton sampling program we took data on various physical parameters at each sampling date. We determined the salinity at the surface and at the bottom in all of our samples. We conducted the salinity sampling with the NIO water sampling bottle taking a small aliquot from the bottle in a salinity sampling jar and reading the value in the laboratory on an inductive salinometer. These salinity data are presented in Appendix II. We also measured the transparency of the water with a secchi disk reading, measuring the visibility by determining when the disk was no longer visible from the surface. This turbidity or visibility measurement is also tabulated in Appendix II. We also obtained data on the color of the water by the use of the Forel scale. This scale is used to compare the color of a sample of water with a series of color comparitors that are provided as a part of the reading device. In general a yellow green to yellowish color in the water is indicative of a high level of plankton and hence probably a high level of productivity, while a blueish color in the water is an indication of the absence of particulate matter in the water and probably ,a low productivity in that region. Again we have provided the Forel scale readings in Appendix

II. The final physical parameter that was measured was the temperature of the water at the surface and the bottom. The surface temperature was obtained from a bucket thermometer hung overboard at approximately one foot depth. The bottom temperature was read from a reversing thermometer attached to the NIO water sampling bottle. Again these temperature measurements are provided in Appendix II. At this time we have not had enough time and experience with the measurement of the physical parameters to ascertain fully their value in this type of program. Therefore, we proposed to continue making this series of measurements which are not expensive or time consuming and developing means for determining the meaning of these physical parameters in terms of the samples of zooplankton that we obtain in a given region. It will be especially easy to obtain these samples if we are able to equip a dory with a hydraulic system that includes two winches. One winch would 9

be used to handle the zooplanktonsampling itselfand the second winch would be used to obtain waterfor the measurement for thevarious physical parameters.

Behavioral Studies

During the summer of1972 we attempted to dive several times to determine the feasibility of makingbehavioral observationsof various marine organisms in thisarea. Our attempt was touse scubagear and to record visually some of the behaviorparametersof importance. We foundthat this does,not appear to bea practical working modeat this time. Our difficulties weretwofold. In many of thenearshore areas we foundthat it was impossible to work safely duringthe time that the oceanwas at all rough. The surge produced by the swellcould throw a diver into a rock orotherwise injure him while working in thiszone. However, a much moredifficultproblem wasvisibility. It is our estimate that you would be able toseeadequately to conductbehavioral studies something less than10% of the time during thebetter summermonths. At all other times thevisibility appearsto be less than 20feetand makes it very difficultto conductany direct behavioralstudies inthisenviron- ment. Since we cannot plan aprogram based only on observations that can be made10%of thetime,we feelthat we must exploreother modesof operation or set up special laboratory studiesto conductthe needed behavioral studiesthat are relevant in the nearshorezone. We are continuing to search for a protected areathatprovidesthe specialconditionsnecessary for the conduct of such fieldstudies. However, the prospectsdo not appear to be particularly encouragingat this time.

Large Animal Sampling

Due to the lateness of startingour work in the summer of 1972 and due to the difficulty in obtaining equipment for suchsampling we did not get started with this work during thatyear.We have used the time since then to obtain equipment and to design additional equipmentfor these specific studies.We also hope to have a dory that will be equipped witha winch large enough to handle this equipmentfor our studies. 10

We did have one day of experience in handlinga beach seine and in using a dory to set the seine outside of the surf zone. The method appears to be workable. That is, the dory is very successful in coming ashore, leaving a line on shore, going out and setting a seine parallel to the beach, and returning to shore with the other line. Our method of operation would be to then have the dory leave the area to minimize disturbance of the fish in the area and then at a time after the dory has leftwe would pull the seine from the shore. However, we also learned that pullinga beach seine from the shore is in fact a massive undertaking. It will be impossible to pull such a seine by hand. It will be necessary to have some type of a shore based winch that will allow us to properly fish a seine in this area. We now have also obtained the necessary permits from the Oregon Fish Commission that will enable us to sample in this area with any type of sampling device, including a gill net, if we desire. We feel that the gill net will be necessary to obtain samples of some of the faster moving species in thisarea. Our otter trawls and mid water trawls will be too slow to capture these animals and we feel it is doubtful if we will be able to capture such species as salmon in a beach seine. We will also consider the feasibility of sampling organisms such as salmon by a typical sport fishing rig. At least we will study the statistics necessary to determine how often we would have to fish ina region to obtain the data about the catch per hour effort. If the feasibility studies prove good we will plan to incorporate suchan experimental fishing program into our 1974 program. We will plan to obtain physical data at thesame time we are making our large animal samples. We will be particularly interested in temperature and salinity measurements, the stage of the tide, and the time of the day,as well as the turbidity. It will be important to correlate our catches of fish with these factors. A major emphasis will be placed upon the large animal sampling program during the summer of 1973 and at that timewe will be able to assess our position in this field. 11

Benthic Sampling

We will begin a program to study both the infauna and the epifauna in this nearshore region. We will use crab pots to study the epifauna and will modify the crab pot to a finer mesh size than that which is used by the commercial fishermen. We will also use various bottom dredges to study and obtain samples of the infauna. We realize the difficulties in these studies but we also realize that they must be done. We will attempt to pull a dredge through the surf zone to obtain samples in thatarea and we will also usethe dredge farther offshore to examine the benthic popu- lations in that region. We again can make little comment about our success in that area, since our efforts will not start until thesummer of 1973.

Introduction to Current Studies

The problem of nearshore circulation is complicated by the number of forces that can cause water movement in this region.Wind, tides, wave transport and offshore current systems can all produce local currents and obviously do not all need to be moving in the same direction andcan change quickly with time. The bulk of the current study effort to date has been concerned with developing techniques to measure the surface water movement and to determine the causes of these movements. Working as close to shore as we do means that large vessels cannot be used and also that there are times when the sea is too rough for the small

boats to operate safely. Therefore, techniques for observing from shoreor light aircraft are most desirable and we have spentsome time considering these possibilities.

The standard method of measuring currents employs current metersof various types. We did not spend time in our observation period with them partly because the technology of current meters iswell known and we wished to experiment with other- less expensive - methods. This is not to say we feel they would not be useful or even necessary in a final survey, but one should have a fair idea of where they should be placed before deploying a network. That idea can be gained most inexpensively by employing free floating objects whose path can be followed. Thus we experimented with a variety of devices designed to give an overall view of the surface current patterns. 12

Drift Bottles and Bags

A drift bottle is simply a transparent bottle, in our case beverage

bottles of 10-12 oz capacity, with a card inside which is numberedso the position and time of release can be recorded. The bottle is weighted with sand so it will float properly witha minimumarea exposed to the wind and capped in the conventional manner. The bottles were released from our vessel at various distance from shore but all were released from within two miles of the beach. The card inside instructs the finder to return part of the card to the School after noting the time and place of recoveryon the card. Obviously we cannot tell the trajectory of the bottle, only the starting and end points but the generalmovementof the water can be determined and we can gain some idea of the speed of movement if we can recover the bottles promptly.

To get a good idea of the time elapsed between drop and recoveryon shore we searched the beaches ourselves for the bottlesso we did not have to rely on returns from the public. We dividedMoolackand BeverlyBeaches into1/8 mile zones sothe recovery positions could be easily recorded. If the bottles come ashore at other beachesalongthe coast we had to rely on the public. Besides giving us an estimateof the time it takes surface water to appear on the shore immediately landward of the drop we can also determine whether the surface flow is predominantlyonshore, alongshore or offshore and whether there is a separation of these flows by distance offshore.

We also experimented with small plastic sandwich bags partly filled with water to give some weight and with only an identifyingnumberin them. This precludes returns from the public but isa less expensive way of operating. However, we found, from simultaneous drops of bottles and bags, that the bags came ashore slightly sooner than the bottles. This fact, coupled with observations of this behavior from the boat makesus feel that they are more affected by the wind directly and, therefore, a less satisfactory tracer of the surface water movement. Also the lack of public returns prevents us from learning aboutmovementsaway fromour immediate area. Therefore, we did not use these much after the middle of August. 13

TableI summarizesthe returns from all our dropsexcept those made in January1973. The returns from which are not yetcomplete.

Date (1972) NumberDropped % returned 10 June 240 7 26 June 108 84 6 July 120 76 19 July 110 63 9 August 120 70 17 August 24 50 18 August 24 58 7 October 48 41

Exclusive of the drop of 10 June this gives an overall recovery rate of 69%, a very high return rate. The 10 June drops were made further offshore than usual and with an east (offshore) wind. Some preliminary inter- pretations of these results will be given in the Result section. This data is found in Appendix III.

Drogues Followed From Shore

To gain a better idea of the actual water trajectorieswe designed some surface drogues (devices designed to follow thecurrents and whose position can be determined at any time by one of several methods). These consisted of circular plywood disks, paintedorange, with crossed vanes beneath them to be pushed by the water. We experimented with severalsizes and vane depths and found 3-foot diameter surfacesgave adequate visibilityand 6-inch deep vanes were fine. We launched a number with differingvane depths from the same location on one day to determine ifwe could detect any difference in movement due to current changes with depth. Although the drogues did not maintain their original orientationwe concluded this was due to diffusion and did not indicate any noticeable effectof variable currents. We determined positions of these droguesby observing them with surveyors instruments from the shore. We found the standard meteorological theodolite (an instrument likea transit that gives elevationangles as well as azimuth) insufficiently accurate since itcan be read to only 0.1° of arc. We used a surveyors theodolite, loaned by the Civil Engineering Dept.,which could be read easily to 20" ofarc and this proved sufficient. We were able to 14

obtain readings as fast as every one minute if the speed of the drogue required it and could follow then for several hoursat this rate although the observer began to be fatigued about then.

We generally tried to recover the drogues from thesea before they became entrapped in the surf andcame ashore. On several occasions we let them come ashore and tried to follow them but they tumble in the surf and their motion there is no longer representative of the water motionso little is gained by this.

In the Results section we will discusssome of the implications of these measurements together with the drift bottle data. As a technique for

determining the nearshore currents in detail the methodseems admirable. It is inexpensive and gives quite good detail. We have developed a computer program which gives the velocities each minute and can smooth out some of the irregularities. The program can be expanded to give statistical details of the motion if this should appear worthwhile later. Furthermore, the technique can be adapted to determine other details of the flow using mul- tiple drogues whose positionsare not recorded so often. This data is found in Appendix IV.

Die Markers Dropped From Aircraft

Because weather conditions sometimes prohibit small boat operation, particularly in winter, we experimented with dropping die markers into the ocean from a small aircraft and following them from the airplane. We did this in a particularly severe weather condition- 40 knot winds from the south and rain. Nevertheless we were able to drop two markers which could be followed for over an hour from the plane. Deriving quantitative data from this operation is more difficult because aerial photography, while possible, could give only the relative position of the markers since it was not possible to keep a known point always in the picture. However if some object that could be jettesoned from the plane that also could be tracked from shore could be developed we could be muchmore independent of the weather. We did try following die markers from the shore but this was not successful: they cannot be seen at the angles even from the bluffs. 15

Drogue Study From Ship

From 2-5 Jan. 1973 we were able to use R/V YAQUINA to studythe nearshore circulation by using regular ship launcheddrogues (The ship was available for this purpose because another study conductedby WPE for NSF could be combined with drogue studies: therefore there was no cost to this particular project.) This method consists of launchinga drogue consisting of a float carrying a mast witha radar reflector with a parachutesuspended underneath. The parachutehas somuch more drag in the water than the mast in the air that the whole thing follows thewater. The parachute can be deployed at any designed depth. For the most part we opened ours just beneath the surface so we followed the integratedcurrent in about the first 5 meters of water. The ship's radar is then used to determine the position of the drogues every fifteen minutes with referenceto some fixed location - either an anchored buoy ora point of land if close enough. In this case we laid out a line starting from 1 mile off Yaquina Head with 6 drogues spaced at 1/2 mile intervals. We followed the drogues for about 40 hours or until they disapppeared from radar range (one came ashore and two drifted out of range but we were able to geta final point when we recovered it). This is much longer than is usual for thistype of operationand we were fortunate to collect some of the best data taken thisclose to shore. Computer programs are available to reduce, plotand perform some preliminary analysis of these data. At this writing we have not completed the analysis but some preliminary conclusionscan be made and will be discussed under Results. This data is found in Appendix V.

Electromagnetic Current Meter

On 19 October we tested an electromagneticcurrent meter owned by the School to see if it could giveus some useful data. The probe is mounted on a 15' pole on the side of a small boat and the probecan be read while the ship is underway. This of course includes the ship's motion but timechanges in the current can be noted and the absolutecurrent calculated if the boat's velocity is known. While data can be easily recorded the analysis is not simple and must be doneon acomputer. To date only preliminary printouts have been obtained andso no more can be saidof the data. The instrument 16 might well be useful in conjunction with other measurements but theanalysis time will have to be considered against other factors, particularly since it gives too much information forour particular purposes.

CUE Data

Much of the data produced by the CUE program is of interest to us. We have the complete summary of the meteorological data which is in a large format book plus the hydrographic data.Some special drogue measurements were made during the period by groups from California and Connecticut which will be available to us as soon as they have been analyzed by the scientists who directed this part of the program.This should be in a matter of weeks from this writing. We list below some of the special observations which will be available and one of particular interest to our program.

We have notyet incorporated all the CUEdata into our analysis program but they willbe useful in interpreting our description of the nearshore circulation. Also the overall CUE program results on the reaction of the water to changesin wind velocitywill guide our subsequent analysis even though notdirectly observedin ourarea. It should be mentioned in passing that some of ourdrift bottledata have been quite useful to the CUE program as well.

Results ofCurrent Studies

The most obvious impressionwe get froman overall view of our data is that thenearshorecurrentsystem is quite variablefrom day-to-day. It is difficult to extractgeneralstatementsabout the circulation and consequently impliesthata given site cannot begin to be understood on the basis of a few 17

measurements. In general the wind seems to be the most importantsingle feature: all our data show good correlation with the winddirection. Both the drift bottles and the drogues go downwindwhen the wind ismore or less parallel to the shore. In one case (10 June)we dropped a number of bottles with east (offshore) winds and foundnone on our beach and onlya 7% return from the public overall. In view of our usual experiencewe have to conclude that these were blown well out to sea and probablydrifted South subsequently. Because we dropped these farther out than subsequentdrops (we were using R/V CAYUSE which couldnot approach nearer than 1 mile from shore) we don't know what happens quiteclose. In general the water movements closer than 1/4 milefrom shore almost invariably are toward shore even if the windsare parallel to it. Almost all bottles and drogue observations indicatea long-shore drift with a slight component inshore. There is some evidencethat seaward of 1/4- 1/2 mile the drift is slightly offshore since bottles droppedthere are generally recovered North or South of our beach. Once the droguesor bottles are caught in thesurf zone they come ashore quickly and as might beexpected their motion becomes less dependent on wind andmove dependent on the surf and the set of the tide. It is not always true, however,that the bottles come on shore only withan incoming tide. Furthermore, the tidal currents have considerable effectonthe speed and direction of flow and can be the main cause of motion if thewinds are light. We have yet to see motion against the wind but this doesnot seem impossible.

In general then there is someevidence that the nearshorezone may divide into two regions. In the closestone the probability that the surface water has a strong on-shore component and that material releasedat the surface there will be found on the shore within a few hoursand within a few miles of the release point. Seaward of this zone materialwould drift along shore for much greater distance and times. At times the boundarybetween the zones appears to be quite sharp- less than 1/4 mile thick. At present we cannot say whether this is a feature typical of all coastsor whether the presence of headlands to the north & south contributeto this apparent pattern. Thissame pattern was noted inour January data. All the drogues showed the influence of the tidal motions but thedrogues launched furthest 18

from the shore showed a net drift toward thesouthwest whereas the middle two drogues showed a net drift to thenorthwest and the inshore paira very slight drift toward the west.

Some mention should be made of thefate of those bottles which did not come ashore in the immediate vicinity of the drifts. For the most part they were recovered, whether northor south, within 15 miles of the release points but some travelled as far north as Cape Kiwanda and some as far southas Waldport or beyond.

One bottle, dropped 11/2 miles offshore, was recovered off themouth of San Francisco Bay 500 miles south. This has receivedsomenotoriety because heretofore itwas not expected that waters that close to shore would drift that fast (ti 1/3 knot average). We also received returns from as far south as Bandon, Oregon. There were indications thatsome clusters would drift south with the wind and thenturn north as the wind shifted and pass the beach and end up around Pacific City. These data have been of much

interest to the CUE study and will beof help to them in their analysisas well as indicating tous that considerable offshore drift can occur from distance fairly close to the beach.

One further observation should be discussedbecause of its implication for biological sampling as wellas for its suggestion about water movements. When we dropped a die marker from the airplane one of the markers spenta great deal of time following alonga foam line. Judging from the known size of the package the foam linewas only about 1foot wide and yet remained

intact with the marker floating in itfor some distance even though thesea was quite rough and the wind very strong. Foam lines havebeenthought to be areas of convergence where thesurface waters come together and sink leaving the floating materialat the surface. Our chance observations would seem to confirm this and also to suggest thatthere may well be a number of regions where convergence and divergenceexist. The same phenomenon was seen, on a larger scale, duringone of the CUE tests where drogues laid out perpendicular to the shorewere found subsequently in a line parallel to the shore. Such regions of convergence and divergencecould quite possibly affect the distribution of planktonand, therefore, those organisms that feed on them. Thus it seems imperative to investigatethese regions since this could lead tovery uneven distribution of organisms in these waters and increases the difficultyof obtaining representative population samples.

Appendix I showsan example of the data collectedon one day's run. Only the results ofa single days measurements are shown, sincethe variability encountered during thisfirstyears operation was so great that we have little confidence inthe actual meaning of the numbers.Both the field data and lab work-upanalysis are presented. The following pages contain the results of the spectrophotometric determination of chlorophylls, phaeopigments and carotenoids in phytoplankton crops.The procedures and equations may be found in Strickland and Parsons A Practical Handbook of Seawater Analysis.
