The School of Oceanography, Oregon State University, initiated a study during the spring of 1984 to investigate the utilization of Netarts Bay by juvenile churn salmon. Specific objectives the first year were to determine: 1) the relative numbers of hatchery arid wild churn salmon, 2) the nursery areas utilized by...
Knowledge of the pelagic organisms in vast areas of the open ocean is very limited. This is particularly true of the small nekton or swimming forms such as fishes, squid, prawns and euphausiids, which are important as intermediate animals in the food chain and are preyed upon by species such...
This report is an intermediate step in analyzing part of the hydrographic data from the 1972 Coastal Upwelling Experiment (CUE) off the coast of Oregon. It presents the author's interpretation of the vertical distribution of temperature, salinity and sigma-t along lines occupied on hydrographic cruises by R/V Yaquina during CUE....
As a result of the past three years of field studies and our interpretation of these and other data from the literature, we conclude that there are inputs of hydrothermal fluids into the bottom of Crater Lake. The dissolved materials associated with these thermally and chemically enriched fluids, coupled with...

Submarine hydrothermal systems provide all of the
conditions necessary for the abiotic synthesis of organic
compounds, polymers, and simple cell-like organisms. An
analysis of the Archaean rock and fossil record shows that
fossils of simple organisms are found in rocks deposited in hydrothermal environments. Biochemical experiments have
shown that thermal...

carried out by the Oregon State University optical oceanography group and
by the Naval Postgraduate School...
Our primary purpose in developing this instrument is to measure
vertical temperature fluctuations in the ocean to the smallest scales at
which they exist. This goal dictates the basic concept of the instrument,
as C. S. Cox saw in the 1960's. Vertical temperature changes are seen
as changes with time...
This report is a preliminary presentation of temperature microstructure

experiment, the Caldwell research group conducted 381 casts over a period
of 21 days from the R/V OCEANOGRAPHER, using a Microstructure...
Precise chemical analyses of geological samples continue to play an
important role in geochemical research. During the past 10 years atomic

accurate and relatively simple analytical technique. The marine geochemistry
group at OST7 has used a Jarrel-Ash 82-820 atomic absorption
spectrophotometer (AAS)...
Our major effort since initiation of this contract has been directed

A numerical model was developed which predicts the dynamic
response of a single mooring line and a buoy of forty feet diameter
to sinusoidal waves, wind and current in all deep waters. All forces
and reactions were considered to be in one plane.

We designed an experiment to see if turbulence induced by shear instability
could be a mechanism. Using equipment readily available we completed
an experiment from the Ice Island T-3. A sensor array of current meters
and thermistors (described later on) was suspended beneath the sea ice of
Colby Bay, T-3,...
Various methods of presenting and mathematically describing particle

distribution is found to be the most practical but the more complex
characteristic vector analysis is the most sensitive to changes in
the shape of the particle size distributions.
Particle size distribution, nutrient concentrations,...
