Three 600 meter casts were takenduring the March cruise to obtain ocean current data and to test ther-mometers for usein future deep casts. At one deep station phosphatesamples were collected and returned to the laboratory for analysis.Duplicate samples for dissolved oxygen determinations were collected inorder to determine the adequacy of our methods of handling and analysis.Surface temperature and salinity samples were collected at 10 mileintervals throughout the cruise tracks.Clarke-Bumptis plankton tows to 200 meters depth were taken at each station.Biological dredge hauls which collected sedimentary rock samples were madeoff Stonewall Bank and Heceta Bank off Newport. According to Dr. Byre,dating of these sediments by the U. S. Geological Survey shows that foram.i-nifera contained in sediment samples from Stonewall,Bank were of recent origin.Successful trial tows to test gear were made with the Isaacs-Kidd MidwaterTrawl and 20 foot Otter Trawl.Coastal Temperature and Salinity Data Bruce Wyatt.A report is being prepared. to summarize the temperature and salinity datacollected, usually weekly, by cooperative observers along the Oregon coast.Plankton Inventories -- Herbert Frolander and Douglas Manske.The series of weekly collections of data in Yaquina Bay was continuedthroughout the quarter and now covers a period of 17 continuous months.---2-The following samples were taken weekly at each of two stations:I drogral,hic data:Surface and bottom water samples, from which salinityand dissolved oxygen have been determined. Measurementof temperature at surface and bottom.Biological data taken each week:Two quantitative plankton tows, one of number six meshnet for adult forms, one of number twelve mesh net forlarval forms. One non-quantitative tow using a half-meter number six mesh net, for identification purposesand collection of less common species.Total samples during period:Fifty-two each of salinity, dissolved oxygen, andtemperature. Twenty-six each of the net hauls.The counts of the major zooplankton species and of the total fish eggsand larvae have been completed through February, 1961.Accessioning -- Herbert Frolander.All biological samples taken during this period were accessioned aspart of the continuous series collected since November, 1959.Accessioning consists of making up labelled, chronological seriesof cases, entering the history of each sample into the permanentaccessioning ledger, and entering a duplicate history of each sampleinto the permanent reference card file.In order to ascertain the relationships hetw,nen zooplankton and theirnutritional value, aliquot subsamples of the half-meter net samples havebeen extracted from each weekly tow and frozen for future chemical analyses.Trawl Collections -- William Pearcy.During the monthly cruises several experimental trawl collections havebeen made and snecimens taken have been identified. One half-hour nighttow of the Isaacs-Kidd Midtwater Trawl, for e_;ample, yielded 675 ml(settled volume) of microplankton and small nekton, a volume which iscomparable to those of the Washington coast (Aron, 1.960). The catcheswere dominated by eunhausids but three species of lantern fishes weretaken; fish eggs, medusae, and chaetognaths were common. Otter trawlcollections incluced many species of fishes, especially flounders and-3-rockfish. One collection (with a commercial shrimp net) on sand bottomtook a large number of a non-commercial shrimp, genus Cao. A systematicprogram of collections with both mid-water and otter or bottom trawl willbe initiated shortly.Aron, +Jilliam., The cl%st.ibuti_on oF nnimals in the eastern North Pacific- -and .ts rd r ti.onship to phvs; cnl and chemical condi_.ti ons," Tech.Rep.

Twenty-eight ofthe samples were of beach sands, 10 of ancient dune sands, 6 of recentdune sands, and 20 of estuarine sands and silts. Heavy mineral analyseswere made of 31 of these.Petrographic examinati.on of the heavy mineral, components of 17 of thesamples revealed local as well as environmental. differences. In generalthe heavy mineral content of the dune sands is highest, averaging 14%of the total beach sands. Alteration minerals, such as Leucoxene, aremost abundant in the ancient dune deposits, which are slightly finergrained than neighboring beach sediments. Although hypersthene is inmost of the beach and dune samples, it is present only in the lowerparts of the estuaries, indicating that much of the lower estuarinesediment is probably derived from the ocean. The source of the hyper-sthene clearly seems to be in areas other than the Oregon Coast Range,,and is probably being contributed to the coastal sediment system bythe Columbia River..Water Masses off the Oregon Coast -- June Pattullo and Donald Rosenberg.A pilot study has been begun. on the waters between the depths of 100and 300 meters off the Oregon coast. All available data for the areabetween the coast and 1300W are being examined. 'Characteristics studiedare the temperature and salinity structure, the spatial distributionof sigma-t surfaces, and the dissolved oxygen and nutrient content ofthe water. On the basis of this preliminary work, a program will beformulated for a detailed sampling program during the forthcoming year.It is anticipated that this study will lead to useful. results concerningthe life history of offshore water masses, their relationships to marinepopulations, and especially the source and nature of water upwelled alongthe coast.-4-Seasonal Heat Storage in the Pacific Ocean -- June Pattullo.Temnerature data collected at Island Observatories during the InternationalGeophysical Year have been analyzed to determine seasonal, variation inheat storage in the upper 400 meters of the ocean during; that period.As a result of the collection of data at nearly a dozen. Southern Hemisphereand Equatorial locations where observations had been lacking before, it ispossible for the first time to determine the variations in storage inthese areas. Northern Hemisphere collections make possible a comparisonbetween the IGY data and averages from earlier years.Although the eastern North Pacific.exhibited somewhat anomalous temperaturevariations during the IGY, the results as a whole are consistent withearlier estimates for the Northern Hemisphere. Therefore, the generalfeatures of the variations observed during IGY are considered adequate asa first approximation of average conditions. A paper on the results hasbeen prepared and is to be presented at the meeting of the American GeophysicalUnion in April.FACILITIESResearch Vessel ACONA.Construction of the vessel. was completed in the quarter, and it waslaunched on 13 February, 1961.
