Norman Farrow William Gilbert Vernon Johnson Donald Keene Jan Naidu PROGRESS REPORT 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 on the 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 meaningful start 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 studies of surface currents and of phytoplankton and zooplankton distribution have been initiated and significant progress has been made. In these cases the studies have been adequate to enable us to do a more effective job of planning for future needs in these study areas. 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 shifting our operations to Newport and basing most of our personnel there for the summer. This will increase our efficiency by allowing us 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 evaluate the 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 working season indicates that the Pacific City-style dory is a 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 that we need for this pro- gram. 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, in a well, necessitates the use of an extra man for handling the dory as 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 sand as we are coming to the beach. This type of motor also leaves us 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 when we were caught in a fog. We also find that we were unable to locate and replicate a station with any degree of accuracy without the help of a triangulation from shore. To remedy this situation and to reduce the man power requirement imposed by such triangulation we feel that a radar and fathometer system will aid us greatly in making the best use of the dory. We will also propose the use of a jet powered dory to increase the efficiency of our operation. Although we did not have any large effort directed toward large animal sampling last summer, we did do enough work with the dory in the surf to deter- mine that it would be set a beach seine with the dory and then move the dory out of the way and pull the beach seine from the shore. We will use the dory for this type of operation during the coming summer. We will also use the dory to pull conventional otter trawls and bottom sampling devices through the surf zone under favorable conditions. possible to 3 Phytoplankton The data presented in Appendix I are representative of the phytoplankton data that were collected during the 1972 period. The procedure for the collection of these data is as follows: An NIO water sampling bottle is used for collection of one liter water samples. The use of this bottle allows sampling to occur at any depth from the surface to the bottom within the nearshore zone. The bottle is an adaption of the Nansen type reversing water sampler, which reverses and locks in place at a particular depth to take the desired sample. The water sample so obtained is then processed in the following way. The water from the NIO bottle is placed in a one liter plastic bottle and the one liter plastic bottle is submerged in a water bath on the boat to maintain it at its correct temperature. The water bath is also designed to reproduce the approximate light intensity that the phytoplankton would be encountering at their depth of collection. This light intensity is reduced for lower samples by the successive addition of screens to the top of the water sampling container. The phytoplankton samples are then transferred 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 time of collection and the time of filtration. On the shore the water samples are processed in a tent, where we are able to filter them through a specially developed one liter filtering apparatus using a 0.8 micron filter. This filter will remove essentially all of the larger diatoms, which appear to make up the majority of the plankton in this area. The filtering device is a pressure filter and in the work last summer nitrogen gas was used to develop the 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 in this frozen condition until time for analysis. The processing of the frozen filters in the laboratory is started by grinding them in a mixer in a solution of 90% double distilled acetone. The solution is then placed in a 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 for a 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 area over a short period of time, since each sample requires a considerable incubation time and requires a longer time for analysis than the samples measured in the way we are measuring. Therefore, we propose to test the validity of this method as a survey method for primary production in a given region and to validate this method against measurements of primary productivity by a carbon-14 method during future years. The data that we have at this time illustrate some difficulties encountered with this type of measurement. The greatest difficulty at this stage is our inability to obtain replicate samples that are showing a consistent value. At this time we blame this on the fact that we have not had enough development time to standardize our 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 greater precision in its use so that we can get the variations between replicate samples taken at the same time and the same place down to a much lower level. Since we did not make measurements of productivity, we will plan to develop the techniques for making such measurements during the coming work period. We will also develop counting abilities to determine population sizes for various major species during this season as well. 5 Zooplankton Sampling The data collected during the past working year on zooplankton are pre- sented in Appendix II. method. All of these data were collected by the following A Clark-Bumpus zooplankton sampling device with a five inch dia- meter mouth and a number 6 mesh net was used to collect all samples. 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 swimming pool) and with this calibration it allows calculation of the number device. of cubic meters of water that flowed through your sampling Therefore, it is possible to count the animals and knowing the number of cubic meters that have passed through the device, it is then pos- sible to determine the number of organisms in each cubic meter of water. A sample thus collected is diluted down to permit taking 3-4 aliquots which, when combined, comprise a subsample containing 400-500 individuals. sample is then carefully counted and identified sex, and stage in the life cycle. The raw data so collected This defined by species, are then pro- means of a computer program to give the results as demonstrated in Appendix II. The use of this computer program saves a great deal of cessed by time in the calculation of densities of organisms in this nearshore zone. Our studies for the last summer have allowed us to develop the techniques for collecting and processing this type of data. necessary We have learned that the dory is in fact an excellent platform for the collection of zooplankton data. The dory used last summer was limited in no power winch for the precise and rapid lowering and recovery that it had of the zooplankton net. Future work in this area will be greatly facili- tated by the use of a dory that has the power winch available for these studies. Although this area of the coastal ecosystem has not been previously studied or sampled, we have confirmed the species distribution with respect distance to time and studies both indicate the are larger to shore could have been predicted from previous within the Yaquina Bay and from farther offshore. occurrence of sampling errors on the replicate than we are willing to accept at this time. The data samples that Therefore, it will 6 be necessary for us to devote a great deal of attention to methods of reducing error between replicate samoles and secondly to providing reliable estimates of the amount of error that is inherent in this sampling method. Only by having information that indicates the size of the expected error will we be able to set confidence limits on future samples that are associated with a particular location. One component of the observed variability is undoubtedly 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 will take this patchiness into account and which will reduce the replicate sample variation due to patchiness. This effort will have a high priority for the 1973 working year. A summary of the data showed that we noted a total of 50 different species in the plankton samples during this study's period. The number of species and the species of maximum abundance varied both with distance from shore and with the time of sampling. Dominant in this analysis were Acartia clausi, Acatia lo ngiremis, various species of Pseudocalanus, Podon leuckarti, and various barnacle life stages. Acartia clausi was most abundant near shore and increased in numbers from July to mid-August and then decreased to mid-September in our sampling. Acartia longiremis was most abundant farther offshore with a rather sizable fluctuation in abundance during the time of the study. Pseudocalanus species were consistently of a higher abundance near shore and relatively stable at all near shore stations with a slight decrease in August. Podon and the barnacle stages became abundant at erratic intervals and especially abundant in September. They are found in all stations from August on and were in the largest numbers on the days of the roughest seas. Studies of zooplankton abundance with depth, indicated that we were finding a maximum in abundance and diversity of species about 15 meters in depth. Therefore, this depth was used as a standard depth for towing our sampling device for the remainder of the sampling period. There is some variation with the abundance of individual species with 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 that minimizes the pumping of such organisms through the industrial operation of interest. The distribution of species and abundance of species in the direction parallel as yet to the shore was noted. Since the meaning of this variation is undetermined, it obviously must be studied in greater detail. variation could again This become 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 organism in particular areas. Therefore, we will repli- cate our efforts and try to determine the importance of towing pattern and headlands under varying wind conditions with the relative abundance of samples attained at different locations parallel to the beach. Additional efforts will be devoted to checking the inherent capabilities 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 the coming summer to try to reduce the variation we see in this type of program. A good deal of further effort is required along these lines to enable us to plan 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 clogging the Clark-Bumpus net. The problem with phytoplankton is of course not 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 con- ducted 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 measure- ments 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 zooplankton would be used to obtain water for sampling itself and the second winch the measurement for the various physical parameters. Behavioral Studies During the summer of 1972 we attempted to dive several times to deter- mine the feasibility of making behavioral observations of various marine organisms in this area. Our attempt was to use scuba gear and to record visually some of the behavior parameters of importance. We found that this does,not appear to be a practical working mode at this time. Our difficulties were twofold. In many of the nearshore areas we found that it was impossible to work safely during the time that the ocean was at all rough. The surge produced by the swell could throw a diver into a rock or otherwise injure him while working in this zone. However, a much more difficult problem was visibility. estimate that you would be able to studies something less than 10% of At all other times the It is our behavioral the time during the better summer months. see adequately to conduct to be less than 20 feet and makes behavioral studies in this environ- visibility appears to conduct any direct ment. Since we cannot plan a program based only on observations that can be made 10% of the time, we feel that we must explore other modes of operait very difficult tion or set up special laboratory studies to conduct the needed behavioral studies that are relevant in the nearshore zone. We are continuing to search for a protected area that provides the special conditions necessary for the conduct of such field studies. However, the prospects do not appear to be particularly encouraging at this time. Large Animal Sampling Due to the lateness of starting our work in the summer of 1972 and due to the difficulty in obtaining equipment for such sampling we did not get started with this work during that year. We have used the time since then to obtain equipment and to design additional equipment for these specific studies. We also hope to have a dory that will be equipped with a winch large enough to handle this equipment for our studies. 10 We did have one day of experience in handling a beach seine and in using a dory to set the seine outside of the surf zone. workable. The method appears to be 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 left we would pull the seine from the shore. However, we also learned that pulling a beach seine from the shore is in fact a massive undertaking. by hand. It will be impossible to pull such a seine 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 this area. 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 organ- isms 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 in region to obtain the data about the catch per hour effort. a If the feasibility studies prove good we will plan to incorporate such an experimental fishing program into our 1974 program. We will plan to obtain physical data at the same 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. fish with these factors. It will be important to correlate our catches of A major emphasis will be placed upon the large animal sampling program during the summer of 1973 and at that time we 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 that area and we will also use the 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 the summer 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 and can 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 shore or light aircraft are most desirable and we have spent some time considering these possibilities. The standard method of measuring currents employs current meters of various types. We did not spend time in our observation period with them partly because the technology of current meters is well 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 numbered so the position and time of release can be recorded. The bottle is weighted with sand so it will float properly with a minimum area 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 recovery on the card. Obviously we cannot tell the trajectory of the bottle, only the starting and end points but the general movement of 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 recovery on shore we searched the beaches ourselves for the bottles so we did not have to rely on returns from the public. into 1/8 mile zones so We divided Moolack and Beverly Beaches the recovery positions could be easily recorded. If the bottles come ashore at other beaches along the coast we had to rely on the public. Besides giving us an estimate of 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 predominantly onshore, along shore 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 identifying number in them. This precludes returns from the public but is a 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 makes us 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 about movements away from our immediate area. Therefore, we did not use these much after the middle of August. 13 I summarizes the returns from all our drops except those made in January 1973. The returns from which are not yet complete. Table Date (1972) Number Dropped % 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 off- shore 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 trajectories we designed some surface drogues (devices designed to follow the currents and whose position can be determined at any time by one of several methods). These consisted of circular plywood disks, painted orange, with crossed vanes beneath them to be pushed by the water. sizes and vane depths and found 3-foot diameter surfaces gave adequate visibility and 6-inch deep vanes were fine. We experimented with several We launched a number with differing vane depths from the same location on one day to determine if we could detect any difference in movement due to current changes with depth. Although the drogues did not maintain their original orientation we concluded this was due to diffusion and did not indicate any noticeable effect of variable currents. We determined positions of these drogues by observing them with surveyors instruments from the shore. We found the standard meteorological theodolite (an instrument like a transit that gives elevation angles as well as azimuth) insufficiently accurate since it can 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" of arc 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 hours at this rate although the observer began to be fatigued about then. We generally tried to recover the drogues from the sea before they became entrapped in the surf and came 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 motion so little is gained by this. In the Results section we will discuss some of the implications of these measurements together with the drift bottle data. As a technique for determining the nearshore currents in detail the method seems admirable. is inexpensive and gives quite good detail. It 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 multiple drogues whose positions are not recorded so often. in Appendix IV. This data is found 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 much more 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 study the nearshore circulation by using regular ship launched drogues (The ship was available for this purpose because another study conducted by WPE for NSF could be combined with drogue studies: particular project.) therefore there was no cost to this This method consists of launching a drogue consisting of a float carrying a mast with a radar reflector with a parachute suspended underneath. The parachute has so much more drag in the water than the mast in the air that the whole thing follows the water. deployed at any designed depth. The parachute can be For the most part we opened ours just beneath the surface so we followed the integrated current 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 reference to some fixed location either an anchored buoy or a 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 get a final point when we recovered it). This is much longer than is usual for this type of operation and we were fortunate to collect some of the best data taken this close to shore. Computer programs are available to reduce, plot and perform some preliminary analysis of these data. At this writing we have not completed the analysis but some preliminary conclusions can be made and will be discussed under Results. This data is found in Appendix V. Electromagnetic Current Meter On 19 October we tested an electromagnetic current meter owned by the School to see if it could give us some useful data. The probe is mounted on a 15' pole on the side of a small boat and the probe can be read while the ship is underway. This of course includes the ship's motion but time changes in the current can be noted and the absolute current calculated if the boat's velocity is known. While data can be easily recorded the analysis is not simple and must be done on a computer. To date only preliminary printouts have been obtained and so no more can be said of the data. The instrument 16 might well be useful in conjunction with other measurements but the analysis time will have to be considered against other factors, particularly since it gives too much information for our 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. Vertical current meters moored in 70-80 m of water 10-18 July, 1972 Hydrographic data from Depoe Bay line 5-17 July KAPPA buoy - moored current meters, 10 miles offshore From 15 April 1972 Aircraft measurements of atmospheric conditions surface temperature, 25 miles surface chlorophyll Tide recorders Drogue trackings mid July - offshore of Newport August 10-17 mid August 2-3 miles offshore Lincoln Beach 7 August, 1972 We have not yet incorporated all the CUE data into our analysis program be useful in interpreting our description of the nearshore circulation. Also the overall CUE program results on the reaction of the water to changes in wind velocity will guide our subsequent analysis even though not directly observed in our area. It should be mentioned in passing that some of our drift bottle data have been quite useful to the CUE program as well. but they will Results of Current Studies The most obvious impression we get from an overall view of our data is system is quite variable from day-to-day. It is extract general statements about the circulation and consequently a given site cannot begin to be understood on the basis of a few that the nearshore current difficult to implies that 17 measurements. In general the wind seems to be the most important single feature: all our data show good correlation with the wind direction. Both the drift bottles and the drogues go downwind when the wind is more or less parallel to the shore. In one case (10 June) we dropped a number of bottles with east (offshore) winds and found none on our beach and only a 7% return from the public overall. In view of our usual experience we have to conclude that these were blown well out to sea and probably drifted South subsequently. Because we dropped these farther out than subsequent drops (we were using R/V CAYUSE which could not approach nearer than 1 mile from shore) we don't know what happens quite close. In general the water movements closer than 1/4 mile from shore almost invariably are toward shore even if the winds are parallel to it. Almost all bottles and drogue observations indicate a long-shore drift with a slight component inshore. There is some evidence that seaward of 1/4 - 1/2 mile the drift is slightly offshore since bottles dropped there are generally recovered North or South of our beach. Once the drogues or bottles are caught in the surf zone they come ashore quickly and as might be expected their motion becomes less dependent on wind and move dependent on the surf and the set of the tide. It is not always true, however, that the bottles come on shore only with an incoming tide. Furthermore, the tidal currents have considerable effect on and direction of flow and can be the main cause of motion if the light. the speed winds are We have yet to see motion against the wind but this does not seem impossible. In general then there is some evidence that the nearshore zone may divide into two regions. In the closest one the probability that the surface water has a strong on-shore component and that material released at the surface there will be found on the shore within a few hours and within a few miles of the release point. Seaward of this zone material would drift along shore for much greater distance and times. At times the boundary between 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 coasts or whether the presence of headlands to the north & south contribute to this apparent pattern. This same pattern was noted in our January data. All the drogues showed the influence of the tidal motions but the drogues launched furthest 18 from the shore showed a net drift toward the southwest whereas the middle two drogues showed a net drift to the northwest and the inshore pair a very slight drift toward the west. Some mention should be made of the fate of those bottles which did not come ashore in the immediate vicinity of the drifts. For the most part they were recovered, whether north or south, within 15 miles of the release points but some travelled as far north as Cape Kiwanda and some as far south as Waldport or beyond. One bottle, dropped 1 1/2 miles offshore, was recovered off the mouth of San Francisco Bay 500 miles south. This has received some notoriety because heretofore it was not expected that waters that close to shore would drift that fast (ti 1/3 knot average). south as Bandon, Oregon. We also received returns from as far There were indications that some clusters would drift south with the wind and then turn 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 be of help to them in their analysis as well as indicating to us that considerable offshore drift can occur from distance fairly close to the beach. One further observation should be discussed because of its implication for biological sampling as well as for its suggestion about water movements. When we dropped a die marker from the airplane one of the markers spent a great deal of time following along a foam line. Judging from the known size of the package the foam line was only about 1 foot wide and yet remained intact with the marker floating in it for some distance even though the sea was quite rough and the wind very strong. Foam lines have been thought to be areas of convergence where the surface waters come together and sink leaving the floating material at the surface. Our chance observations would seem to confirm this and also to suggest that there may well be a number of regions where convergence and divergence exist. The same phenomenon was seen, on a larger scale, during one of the CUE tests where drogues laid out perpendicular to the shore were found subsequently in a line parallel to the shore. Such regions of convergence and divergence could quite possibly affect the distribution of plankton and, therefore, those organisms that feed on them. Thus it seems imperative to investigate these regions since this could lead to very uneven distribution of organisms in these waters and increases the difficulty of obtaining representative population samples. APPENDIX I Appendix I shows an example of the data collected on one day's run. Only the results of a single days measurements are shown, since the vari- ability encountered during this first years operation was so great that we have little confidence in the actual meaning of the numbers. Both the field data and lab work-up analysis are presented. The following pages contain the results of the spectrophotometric determination of chlorophylls, phaeopigments and carotenoids in phytoplankton crops.
