The Response of the Upper Ocean to Solar Heating II
Quart. J. R. Met. Soc. (1986). 112, pp. 29-42 55 1.465.553:ss 1.365.7 1 The response of the upper ocean to solar heating. 11: The wind-driven current By J. D. WOODS and V. STRASS 1n.Ytitrtt ,fuer Meereskunde an der Unioer,rituet Kiel, F. R. G. (Received 28 February lYX?: revised 30 July 1985) SUMMARY The current profile generated by a steady wind stress is disturbed by the diurnal variation of mixed layer depth forced by solar heating. Momentum diffused deep at night is abandoned to rotate incrtially during the day when the mixed layer is shallow and then re-entrained next night when it deepens. The resulting variation of current profile has been calculated with a one-dimcnsional model in which power supply to turhulencc determines the profile of eddy viscosity. The resulting variations of current velocity at fixed depths are so complicated that it is not surprising that current meter nieasurenients have seldom yielded the classical Ekmaii solution. However, the progressive vector diagrams do exhibit an Ekman-like response (albeit with superimposed inertial disturbances) suggesting that the model might be tested by tracking drifters designed to follow the flow at fixed depths. The inertial rotation of the current in the diurnal thermocline leads to a diurnal jet. the dynamical equivalent of the nocturnal jet in the atmospheric boundary layer over land. The role of inertial currents in deepening the mixed layer is clarified, leading to proposals for improving the turbulence parametrizations used in models of the upper ocean. The model predicts that the diurnal thermocline contains two layers of persistent vigorous turbulence separated by a thicker band of patchy turbulence in otherwise laminar flow. -

THE CHAETOGNATHS OP WESTERN CANADIAN COASTAL WATERS by HELEN ELIZABETH LEA A THESIS SUBMITTED IN PARTIAL FULFILMENT OP THE REQUIREMENTS FOR THE DEGREE OF MASTER OF ARTS in the Department of ZOOLOGY We accept this thesis as conforming to the standard required from candidates for the degree of MASTER OF ARTS Members of the Department of Zoology THE UNIVERSITY OF BRITISH COLUMBIA October, 1954 ABSTRACT A study of the chaetognath population in the waters of western Canada was undertaken to discover what species were pre• sent and to determine their distribution. The plankton samples examined were collected by the Institute of Oceanography of the University of British Columbia in the summers of 1953 and 1954 from eleven representative areas along the entire coastline of western Canada. It was hoped that the distribution study would correlate with fundamental oceanographic data, and that the pre• sence or absence of a given species of chaetognath might prove to be an indicator of oceanographic conditions. Four species of chaetognaths, representing two genera, were found to be pre• sent. One species, Sagitta elegans. was the most abundant and widely distributed species, occurring at least in small numbers in all the areas sampled. It was characteristic of the mixed coastal waters over the continental shelf and of the inland waters. Enkrohnla hamata. an oceanic form, occurred in most regions in small numbers as an immigrant, and was abundant to- ward the edge of the continental shelf. Sagitta lyra. strictly a deep sea species, was found only in the open waters along the outer coasts, and a few specimens of Sagitta decipiens. -

To accommodate timely reporting of recently collected information, reports in this series undergo only limited internal review and may contain preliminary data; this information may be subsequently finalized and published in the formal literature. Consequently, these reports should not be cited without prior approval of the author or the Commercial Fisheries Management and Development Division.

Wind-Induced Mixing of Buoyant Plumes
WIND-INDUCED MIXING OF BUOYANT PLUMES Report NO SR 78 March 1986 Registered Office: Hydraulics Research Limited, Wallingford. Oxfordshire OX10 8BA. Telephone: 0491 35381. Telex: 848552 This report describes work funded by the Department of the Environment under Research Contract PECD 7/6/61, for which the DOE nominated officer was Dr R P Thorogood. It is published on behalf of the Department of the Environment but any opinions expressed in this report are not necessarily those of the funding Department. The work was carried out by Dr A J Cooper in the Tidal Engineering Department of Kydraulics Research, Wallingford, under the management of Mr M F C Thorn. 0 Crown copyright 1986 Published by permission of the Controller of Her Majesty's Stationery Office ABSTRACT In the absence of wind a buoyant plume of effluent discharged to the sea some distance from the shoreline is most frequently swept nearly parallel to the coast by the tidal currents. The main reason for a surface plume to approach the beach is if there is a wind blowing onshore. Although the wind has this adverse effect of allowing the effluent to reach the shore it tends at the same time to cause additional mixing so reducing the pollution risk. It is important in planning outfalls to know the extent of this extra mixing. The processes causing plume dilution from outfall to shore are first reviewed in the absence of wind. The presence of a wind is found to cause extra mixing by two important physical processes. The first is the entrainment of ambient water into the plume caused by the turbulence in the plume induced by the wind. -

Sea Surface Microlayer and Bacterioneuston Spreading Dynamics
MARINE ECOLOGY PROGRESS SERIES Published February 27 Mar Ecol Prog Ser Sea surface microlayer and bacterioneuston spreading dynamics Michelle S. Hale*,James G. Mitchell School of Biological Sciences. Flinders University of South Australia. PO Box 2100. Adelaide, South Austrialia 5001. Australia ABSTRACT: The sea surface microlayer (SSM) has been well studied with regard to its chemical and biological composition, as well as its productivity. The origin and dynamics of these natural communi- ties have been less well studied, despite extenslve work on the relevant phys~calparameters, wind, tur- bulence and surface tension. To examine the effect these processes have on neuston transport, mea- surements of wind-dr~vensurface drift, surfactant spreading and bacter~altransport in the SSM were made in the laboratory and in the field. Spreading rates due to surface tension were up to approxi- mately 17 km d-' (19.7 cm S-') and were not significantly affected by waves. Wind-induced surface drift was measured in the laboratory. Wind speeds of 2 to 5 m S-' produced drift speeds of 8 to 14 cm S-', respectively We demonstrate that bactena spread with advancing sl~cks,but are not distributed evenly. Localised concentrat~onswere found at the source and at the leadlng edge of spreading slicks The Reynolds ridge, a slight rise in surface level at the leading edge of a spreading slick, may provide a mechanism by which bacteria are concentrated and transported at the leading edge. Bacteria already present at the surface were not pushed back by the leading edge, but incorporated and spread evenly across the sllck The spread~ngprocess d~dnot result in the displacement of extant bacterioneuston communities The results ind~catesurface tension and wind-lnduced surface drift may alter distribu- tions and introduce new populat~onsinto neustonlc communltles, including communities d~stantfrom the point source of release.
