University deployed two arrays of three sonobuoys over the Blanco
fracture zone and two arrays of four sonobuoys over the Gorda ridge
to detect and locate microearthquakes. Microearthquake activity predicted
by plate tectonic theory for the Blanco fracture zone and Gorda
ridge was observed by these arrays to originate from...
Recently obtained airgun-sonobuoy wide-angle refraction and
reflection profiles provide data to study crustal velocities and
structures along the continental margin of northern California and
Southern Oregon.
In the thick sedimentary wedge at the base of the continental
slope, as many as five distinct layers can be seismically observed,
which range...
Deterministic source signature deconvolution is applied to the
processing of marine wide angle and vertical profiler data with air-gun
sources. Optimum results are obtained with a source signature
measured by stacking the signal reflected from a relatively homogeneous
abyssal plain sedimentary environment. This eliminates the need for
the unstable inverse...
This thesis presents a procedure to identify and evaluate forest
arterial and collector networks. The procedure identifies those
decision criteria important in evaluating both the arterial and
collector networks and the specific facilities identified on these
networks. The procedure incorporates the decision criteria and results
from network and facility analysis...
It was hypothesized that alterations in plasma concentrations of
corticosterone (CS) and prolactin (PRL) may be at least partially responsible
for polychlorinated biphenyl (PCB)-induced immunosuppression.
A 2 by 2 factorial experiment examined the interactions of PCB and P815,
an allogeneic tumor, on plasma concentrations of CS and PRL, and on...
Eight scale characters of known hatchery and wild coho salmon
(Oncorhynchus kisutch) were compared, and a linear discriminant
function was used to determine if hatchery and wild adult coho
salmon could be correctly identified by their scales. Eighty-two
percent of the hatchery and 89% of the wild fish were correctly...
