CORVAWS INTRODUCTION This report summarizes the research conducted during the second quarter of the calendar year 1961 by the Department of Oceanography, Oregon State University, under Contract Nonr 1286(02) Project NR 083-102 with the Office of Naval Research, and Grant No. G 15070 with the National Science Foundation. RESEARCH IN PROGRESS Hydrographic Survey of Oregon Coastal Waters -- Bruce Wyatt. This program has been greatly expanded with the use of the ACONA. During April and May the regular lines of stations, coast to 45 miles offshore from Astoria, Newport, and Coos Bay, were occupied. The 22 to 25 April cruise was aboard the trawler KISKA. Sixteen stations were occupied, most of them to 200 meters; Clarke-Bumpus tows were taken, oblique to 200 meters, at each station, and 288 drift bottles were released. In May the ACONA was put in service, and ran its first regular cruise 22 to 26 May, occupying 11 stations offshore from Newport and Astoria. Observations were similar to those taken in April. In June the track was extended to include a line off Brookings, thus covering the entire Oregon coast, and all lines were extended out to 128°W. Forty-one hydrographic casts to 800 meters were made; bathythermograph observations were taken on each station and at ten-mile intervals between stations. An oblique 200 meter Clarke--Bumpus tow was taken at each station. Three deep casts (one to a depth of 1500 meters) were made to determine pressure responses of unprotected reversing thermometers recently purchased. Plankton Inventories -- Herbert Frolander and Douglas Manske. Weekly samples were collected on 13 days between 1 April and 23 June, inclusive; at each of two stations in Yaquina Bay. The following data were obtained: drographic data: Surface and bottom water samples at each station, from which temperature, salinity, and dissolved oxygen have been measured. Total of 50 measurements of each variable. Biological data. Two quantitative net tows at each station, approximately with number six mesh net and number 12 mesh net. 24 tows with weekly. Total of 29 tows Qualitative half-meter net tows at each station, total of 26 samples. Accessioning .... Herbert Frolander« All biological samples have been accessioned into the continuous collection in ledger and card file, and catalogued in file collection cases. Nekton Studies -- William Pea rcy, Donald Day., Lyle Hubbard* During this quarter all the equipment for sampling and nekton populations, both pelagic and benthic, have been used from the ACONA. These include the Isaacs-Kidd midwater trawl, 22 foot otter trawls, deep-free vehicles, and one-meter plankton nets. A total of 16 midwater trawl samples have been made, including a series of 12 collections which extended over a 17-hour interval at one station 50 miles west of Newport, where the depth is about 1000 fathoms. A few preliminary comments are included on the catch variations of the more important nektonic animals during this series. None of the organisms listed below was taken in surface tows (0-20Qm) from 1500 to 1700 PST. The catches of euphausiids, which were often the predominant animals by volume, indicated that they were very abundant in the upper 200m only between 2300 and 0200; before and after this period their numbers were It is also interesting to note that they were not relatively low. abundant in tows to 50-Om at 1800 and 0700, suggesting a rapid vertical migration to and from the surface waters. Sergestid shrimp were also They were taken throughout the night in about equal numbers and common. were also taken in the tows to 500m. Lampanyctus 1eucosparus, a myctopid, was the most abundant fish in these collections; it was sampled throughout the night with peak, catches occurring about 2400. Other fishes, such as Diaphus theta, Tarletoubeania crenularis, and Tactostoma sp., were commons but their numbers were too low to enable an evaluation of catch variations. All of the above fish were collected in tows to 500m. Chauliodes count was only taken in 500m tows. Fish eggs and larvae have been sorted from weekly plankton samples extending over a year in Yaquina Bay, and the catches per cubic meter have been plotted. Although the pattern of seasonal abundance is less marked than that of other East coast studies, irregular peaks of abundance occur from March to September. Water Masses off the Oregon Coast -- June Pattullo and Donald Rosenberg. Data collected during the June cruise of the ACONA (see Hydrographic Survey ...) are being analyzed to determine the characteristics of the subsurface water (100 to 300 meters) during this period. From prior data, representative stations have been selected where data are numerous enough to yield information on the time variation in properties. One remarkable characteristic of the water at these depths is the systematic increase in dissolved oxygen with distance offshore. In general, a value below 3 ml/L is typical of the water lying within 100 miles of the coast; however, at approximately 1270W an increase to about 5 ml/L is observed. Seasonal Heat Storage in the Pacific Ocean --- June Pattullo. To determine the relationship between seasonal variations in heat content and in advection, the local heating by seasons has been determined for the entire Pacific Ocean by combining the work of Kimball, Jacobs, and Privett on the various heat budget terms. Net advected heat can then be inferred. and compared with possible changes in the circulation patterns during the year. The quantitative work is nearly complete. Shipboard Chemical Analyses of Sea Water -- Kilho Park and Wilson Latimer. During this quarter a Beckman DU spectrophotometer was altered for shipboard use following the modification plans of Mr. Robert J. Linn of Scripps Institution of Oceanography (personal communication). The spectro- photometer was tested at sea during cruise 6106 of the Research Vessel ACONA. Due to heavy weather only 32 inorganic phosphate samples were analyzed during the cruise; the remainder of the phosphate samples were frozen immediately and returned to the campus for analysis on shore. Dissolved oxygen was analyzed regularly aboard ship. Precise shipboard measurements of pH are being planned using a Beckman GS pH meter and a constant temperature bath, They will be carried out beginning with the regular hydrographic cruise in August 1961. at sea FACILITIES Research Vessel ACONA.

Maiden Voyage and en House.; On 5 May the ship made its maiden voyage down the coast to Newport on Open house was held on board the vessel in Newport on Bay. Approximately 1500 people visited the ship and examined the equipment on display. Yaquina 28 May. Regular CLiises Begun. Less than two years after the construction was authorized by ONR Contract, the M. V. ACONA completed her first regular ten-day oceanographic cruise on 30 June. This was made possible, although winds in excess of 35 knots were encountered, by the highly satisfactory performance of the bow propulsion engine. The captain was able to hold the ship on station and in a convenient working attitude with respect to wind and waves. On this cruise 41 hydrographic casts were made over a cruise track the entire length of the Oregon coast sampling more than 41,000 square nautical miles. STAFF Dr Kilho Park has joined the staff as a Research Associate with the rank of Assistant Professor, Dr. Park is a specialist in chemical oceanography. He has written a number of papers on his research in variations of pH, calcium carbonate and dissolved organic materials in sea water. He has been at A. and M. College of Texas for the past six years, except for summer research at the Institute of Marine Science of the University of Texas. Dr. Park has begun analyses of the chemical properties of sea water off the Oregon coast (q.v.) and plans to continue his work on the calcium carbonate-carbon dioxide systems. Dr. Park received his Ph.D. as well as his M.S. in chemical oceanography from Texas A. and M. His undergraduate work was at the University of Pusan and at the Pusan Fisheries College, Korea; he received his B. S. in fisheries from the latter institution in 1953. During 1951 and 1952 he served as an interpreter with the U. S. Marines in Korea, and later received his commission as an ensign in the Korean He taught science in secondary schools for two years before undertaking his graduate studies at Texas A. and M. From June 1959 to November 1960, he was a Predoctoral Fellow in Organic Chemistry at that institution, under the auspices of the Robert A. Welch Foundation. Navy. Captain Chester A. MacNeill, Jr., has left the staff to accept a position with the Columbia River Pilots Association. PUBLICATIONS AND PAPERS Papers Submitted for Publication.
