Using the hydrographic data collected by the ACONA from June
1961 to May 1963, the Oregon coastal front has been examined. Representative
sigma-t surfaces were chosen to delineate the front, and
changes in position of these surfaces with time were used to obtain
zonal flow rates for the frontal and...
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 36 samples collected with a 22-foot semi-balloon shrimp
trawl at depths from 40 to 1,829 meters off the central coast of
Oregon between July 1961 and June 1962 provided preliminary data
on the distribution, species composition, and associations of benthic
fishes with respect to depth and sediment type.
Sixty-seven...
The thesis examines the principal air-sea properties at Ocean
Station Vessel N (30N 140W). In a descriptive section, meteorological
and oceanographic data for N are analyzed over 20 years (1951-1970)
and 7 years (1964-1970), respectively. A rainfall estimate is constructed
for the 20 year period. The yearly average rainfall is...
Daily commercial albacore catches made by U. S. trollers fishing
off central California and Oregon are correlated with daily upwelling
indices and predictive catch models are developed.
Models predicting total catch/day and catch/boat/day are
formulated for the region off central California in 1961 to 1963 and
off Oregon in 1967...
This study investigated long-term (1961-2008) changes in albacore (Thunnus alalunga) abundance and distribution in relation to local environmental and large-scale climate indices in the Northeastern Pacific using time series and spatial analyses. Prior to the time series analysis, a wavelet analysis was conducted to examine nonrandom patterns of cyclical variability...

Three realms of deposition, Marine, Fluviatile, and Marine-
Fluviatile, are recognized in Yaquina Bay, Oregon, on the basis of
sediment texture and mineralogy. The Marine Realm extends 1.5
miles into the entrance of the estuary and is typified by normal
marine salinity and vigorous tidal action. Sediments of this realm...
