The probable pollution distribution and flushing times have been
calculated for the Columbia River Estuary, a coastal plain estuary.
The pollution distribution was determined by the fresh water fraction
and by the diffusion equation. The flushing times were calculated by
the modified tidal prism method and by the fraction of...
The data recorded between March 3, 1969, and October 31, 1969,
by a wind gauge installed at the South Jetty, Newport, Oregon, were
analyzed. The components of each observation were treated as if they
were an independent, normal, bivariate distribution and standard
statistical procedures were applied. It was found that...
This thesis demonstrates that at low frequencies (periods longer
than 2.5 days) local currents off the coast of Oregon are closely
related to the wind. Wind and current observations made during
August and September 1969 are described and compared to demonstrate
that a relationship exists; the physics of the interaction...
This study examines the seasonal variability in temperature and
salinity of the nearshore waters off Oregon and Northern California.
Specifically, temperature and salinity variations during summer and
winter were ana1yzed from data gathered at shore stations along the
coast and from hydrographic data collected within 25 nautical miles
of shore....
Oregon's commercial fishery for albacore tuna (Thunnus alalunga)
is large, valuable, and variable. Little is known, however, about the
oceanographic factors which determine abundance and distribution of
albacore.
Primarily using logbook data contributed by fishermen, this study
compares albacore catches with selected ocean conditions. The study
is limited to troll-caught...
A weather station was established on the dock of the Oregon State
University Marine Science Center, Yaquina Bay, Oregon. A total of
197 weather observations was made from 30 June 1966 to 23 September
1966, with emphasis on the determination of the rate of evaporation
from an evaporation pan and...
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...
The distribution of Antarctic Intermediate Water in the South
Pacific has been examined using a model of horizontal advection,
along the Sigma-t surface 27.10, with three point vertical mixing.
The core of the Antarctic Intermediate Water mass was traced
from the Antarctic Convergence northward. The charts used to
describe the...
