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

migration to and from the surface waters. Sergestid shrimp were also

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.

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.
