Cooperative marine fisheries research—the practice of involving the expertise of
fishermen and scientists in conducting studies of ocean fishes—has increased gradually
over the past 50 years on the US west coast. However, few studies have...

Geophysical and biogeochemical processes associated with fluid venting from active and passive continental margins will receive significant scientific and economic attention
into the next century and are of major societal relevance. An important...

Two Autonomous Underwater Vehicle Gliders have alternated continuous
sampling of a 45-nautical mile transect line (the Newport Hydrographic Line) across
the Oregon continental shelf since April, 2006. Strong currents (>25cm/s) push the
gliders off...

This investigation has been carried out primarily to define the Columbia
River bar crossing problem, to determine the physical factors involved in
hazardous transit developments, and to develop a method for predicting
hazardous bar transit...

This report represents the progress in "Ecological and Radioecological
Studies in the Columbia River Estuary and Adjacent Pacific
Ocean" for the period 1 April 1975 through 31 March 1976. This research
has been supported with funds from the...

Bayocean sand spit lies along the northern Oregon coast
approximately 70 miles south of the Columbia River. Work was
begun on the construction of a large recreational resort on the spit
in the early 1900's. At the outset, the resort appeared to...

Spectral beam attenuation coefficients, spectral volume scattering
function meaurements at 45°, 90°, and 130° particle size distributions
and chlorophyll a and phaeophytin pigment concentrations were measured during
May and September, 1977 in...

The analytical method employed for the Total Organic Carbon (TOC)
project in the Geochemical Ocean Sections Study (GEOSECS) is described
in detail. The method generally follows that of Menzel and Vaccaro as
modified by several subsequent workers...

Various methods of presenting and mathematically describing particle
size distribution are explained and evaluated. The hyperbolic
distribution is found to be the most practical but the more complex
characteristic vector analysis is the most...

Instrumentation for rapid, high precision size analysis of silt and
sand size particles has been acquired and/or developed by the marine
geology group of the School of Oceanography of Oregon State University.
A Cahn automatic electrobalance with...

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....
