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 purpose of this study is to describe Dungeness crab marketing
from the ocean floor to the ultimate consumer; to identify
relations among the Oregon Dungeness crab industry, the Pacific
Coast Dungeness crab industry, and the Alaska King crab industry;
and to specify the relationships between fishermen's prices for
Dungeness...

An investigation was conducted to determine the origin of
Mima mounds in Jackson County, Oregon and Thurston County,
Washington. Data on soil morphology, mineralogy, and particle
size distribution were used to test the periglacial ice wedge hypothesis,
the gopher hypothesis, the erosional hypothesis, and the
loess hypothesis.
The results of...
A study was made to determine biological relationships between the garden symphylan, Scutigerella immaculata (Newport), and an entomogenous fungus, Entomophthora coronata (Costantin), which attacks it under certain conditions. Until this fungus was found to infect this pest, no organism which seemed to offer promise of control had been discovered. Symphylan...
Fannie canicularis is concentrated in areas where animal
husbandry is practiced and frequently comprises more than 50
percent of the fly population. There is a need for more critical
fly control where suburban expansion has invaded animal raising
regions. The purpose of this study is to investigate the use of...
