This report presents observations from a single mooring of velocity, temperature, conductivity, and pressure, made as part of the Ocean Storms experiment, conducted in the N.E. Pacific Ocean (47° 25.4' N, 139° 17.8' W) from August 1987 to June 1988. The mooring contained a total of 14 current meters, 4...
Temperature, salinity, sigma-t and dissipation profiles from the Rapid Sampling Vertical Profiler for six transects as part of the Coastal Transition zone pilot experiment, June 1987.
The fall-winter surface current field off Oregon was determined by analysis of ten years of drift bottle data. Computer programs were developed for generating bottle tracks on a numerical grid, for interpolating bottle velocity components to fill void grid points and for smoothing irregularities in the velocity fields. Charts are...
The geopotential anomalies and the average meridional geostrophic
flow off Newport, Oregon, were computed from the data taken
during twenty-one hydrographic cruises.
The annual average of geopotential anomaly was 1.31 dynamic
meters with a seasonal variation of the order of 14 dynamic centimeters.
Highest values of geopotential anomaly occurred in...
A long and gradual transition between the summer and winter
oceanic regimes was observed off Oregon during the autumn of 1980.
Hydrographic sections and a single current meter mooring between
August and December show the ocean possessed characteristics during
fall that have not been observed during other seasons: a slow...
The physical characteristics of continental shelf waters off
Oregon during late winter and spring of 1975 are described and compared
with observations taken previously during summer. The currents
in winter are barotropic in the monthly means while in summer
the currents are baroclinic. Alongshore current fluctuations on the
time scale...
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...
Using a linear quasi-geostrophic model of large scale spiraling flow and vertical density gradient in the eastern North Pacific, we evaluate the complex dispersion relationships for quasi-geostrophic waves. Our calculations indicate that the geostrophic circulation of the eastern North Pacific can locally convert potential energy to mesoscale kinetic energy on...
