Oregon State University installed and recovered moorings along the coast of Peru during the period late March 1976 through mid-May 1977. A mid-shelf mooring near 15°S (MILA)
was maintained for the full duration of the experiment, through five successive installations. This site was complemented by six other moorings in the...
Sea level and the alongshore component of wind stress data at
seven locations on the Pacific coast of Canada and the United States
were analyzed. The effective data period was from August 1, 1973 to
September 9, 1975. The seven locations were Tofino, British
Columbia; Neah Bay and Toke Point,...
This thesis demonstrates that at low frequencies (periods longer
than 2.5 days) local currents off the coast of Oregon are closely
related to the wind. Wind and current observations made during
August and September 1969 are described and compared to demonstrate
that a relationship exists; the physics of the interaction...
Observations of sea temperature, wind and hydrography obtained
during the three months' period of MAM 77 - CUEA experiment (JOINT-II)
along the C-line, near 15°S are described. Wind and temperature
observations made during March - May 1977 are compared to demonstrate
that a relationship exists.
Linear correlation analysis was performed...
Observations of the hydrographic regime over the continental shelf off Oregon from the R/V Yaquina during the summer of 1972 showed the presence of an alongshore, subsurface ribbon of relatively cool water. Its properties and its evolution during the 1972 season are described. Examination of earlier observations showed that evidence...
Current observations over the continental shelf at locations off central Oregon and southern Washington
had the period from July 18 to September 18, 1972, in common. Low-frequency fluctuations (less than
one cycle per day) in the currents are compared by means of visual display, linear regression, and spectral
analysis. The...
During some of the CODE mooring deployment and recovery cruises, CTD
observations were made on an ancillary basis. In conjunction with the recovery
of the CODE-2 array, CTD observations were made during 3-5 August
(CODE-2 Leg 10) and 19 August (CODE-2 Leg 13). The CTD observations were
made alongside current...
A novel, low-cost instrument capable of measuring surface water PCO₂ was designed for use in dynamic, shallow-water environments. The instrument was tested in the Yaquina River Estuary, a macrotidal estuary known to experience a wide range of conditions ranging from dominance by the coastal ocean during summer upwelling to substantial...
This report presents data collected on six cruises made during the months May-October 1972 along the Oregon coast. Both complete data listings and sequential surface data contour charts are presented. The latter graphically display rapid changes in surface water characteristics on time scales as short as a few hours.
The...
Hydrographic observations were made over the continental shelf and slope off Oregon during the 1973 Coastal Upwelling Experiment (CUE-II) from three ships: R/V OCEANOGRAPHER, R/V THOMAS G. THOMPSON, and R/V YAQUINA. This report contains the observations made on four YAQUINA cruises between June and August 1973 (Table I). Observations were...
Repeated conductivity, temperature, and depth (CTD) sections were made across the continental
margin off Peru at 5°S and 10°S between November 1981 and May 1984, i.e., before, during, and after El
Nino of 1982-1983. Coastal sea level at Paita (5°S) and Callao (12°S) began to rise in early October 1982...
Subsurface upper ocean waters off Oregon and Vancouver Island were about 1° cooler in July 2002 than in July 2001. The anomalously cool layer coincides with the permanent halocline which has salinities of 32.2 to 33.8, suggesting an invasion of nutrient-rich Subarctic waters. The anomalously cool layer lies at 30–150...
Observed changes in the nutrient levels in the halocline of the California Current during 2002 indicated a natural eutrophication that was accompanied by increased chlorophyll and oxygen in surface water. Decreased oxygen in the lower water column over the shelf indicated that much of the phytoplankton production was respired rather...
Sea level and current data collected near Newport, Oregon are
compared to determine an empirical relationship from which the low
frequency (f < .1 cpd) alongshore current field over the continental
shelf is estimated from observed sea level measurements at the coast.
Regression analysis of the near-surface (20-25 m) currents...
Two mesoscale surveys were conducted (in July 1981 and July 1982) near Point Arena, California, to
determine the structure and circulation associated with tongues of cold surface water extending seaward
from the coastal zone. Both surveys were designed at sea on the basis of available satellite IR data, and
each...

on alongshore sections 40 km apart. All...
From the Dennis Barstow Photographs (P 280) in the OSU Archives. The Dennis Barstow Photographs consist of color slides taken by Barstow of oceanographic research conducted on Oregon State University research vessels. Dennis Barstow joined the Oregon State University Oceanography Department in 1962 as a research assistant. He served as...
The dynamics of the coastal transition zone off Northern California during late May and early June 1987 art
examined through assimilation modeling studies. A regional baroclinic quasi-geostrophic model is driven by the
data through initial and boundary conditions. These initial and boundary conditions are specified by objective
analysis of hydrographic...
Models were developed that described cohort strength of female
Dover sole (Microstomus pacificus) and female English sole (Parophrys
vetulus) in stocks off the Columbia River as functions of environmental
variables. The environmental variables considered were those
that could hypothetically influence spawning success or survival.
They included a spawning power index,...
We sharpen our view of an eastern boundary current region during
the upwelling season through the analysis of several data sets.
We focus on the mesoscale flow field off of northern California,
observed during the Coastal Transition Zone (CTZ) experiment of 1988.
First, we estimate tidal currents in the region...
