The oceanic phenomenon of upwelling along the Oregon coast is
examined. Upwelling in both the open ocean and coastal regions is
discussed. An idealized model is used, envisaging the ocean off
Oregon to consist of homogeneous surface and deep layers separated
by a pycnocline. The equations of motion are solved...
Current and conductivity, temperature, and depth (CTD) measurements were made over the Oregon
shelf near 43°N between February 1981 and April 1984 as part of a large-scale west coast shelf experiment
(SuperCODE). The data set includes a nearly continuous record of current velocity and temperature
over the continental shelf off...

Three deep-sea subsurface moorings, each equipped with five current meters at depths from 150m below the surface to 200m above the bottom, were deployed off Northern California from September 1984 to July 1985 as part of the OPTOMA program. The triad of moorings, centered near 38.5°N, 125°W, had mutual separations...
This report summarizes the SeaSoar and CTD observations from R/V Wecoma cruise
W9408A (23 August to 2 September 1994) conducted as part of the Coastal Jet Separation
(CJS) experiment, under funding from the National Science Foundation. The goal of this
study is to establish how and why a strong alongshore...
Current meter moorings maintained over the Oregon continental shelf in 1973 and 1975 clearly show the difference between winter and spring oceanographic regimes and the rapid transition between the regimes. In winter the mean alongshore current is northward at all depths and strongest near shore; there is no mean vertical...
Near‐inertial motions were observed at all current meters in an array of five moorings spanning the continental margin off central Oregon during October 1977 to January 1978. All moorings were between 10 and 130 km from shore, in water depths between 100 m and 2500 m. Largest near‐inertial amplitudes (>30...
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...
Past measurements off the coast of central Oregon and Washington have shown that the rapid change
from northward monthly mean winter winds to southward summer winds forces a "spring transition" of
the coastal ocean: sea levels and temperatures drop, and mean surface currents shift from northward to
southward. Current and...
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...
