A proposed modeling technique that yields a best fit to observed
wide-angle reflection profiles incorporates (1) the use of migrated vertical
reflection profiles to provide topographic control, (2) ray tracing
to produce theoretical wide-angle...

Holocene bulk sediment and component accumulation rates were
measured in twenty-eight piston and gravity cores taken from the
floor of the western Panama Basin and on the surrounding ridges.
Radiocarbon ages and oxygen isotope curves provided...

Extensive new trackline coverage of the Chile Trench between
23°S and 34°S, including more than 60 bathymetric and seismic reflection
profiles across the trench axis, allows a much more detailed
study of the tectonics and sedimentation of this...

Sediments of a portion of the central Oregon shelf between 17
and 339 m have been examined for modern foraminifera. Eighty-three
samples were collected from 33 stations along three traverses
located between 43° 16'N and 43° 50'N. One hundred...

The Cocos Gap is a deeper portion, or saddle, of the Cocos
Ridge and forms part of the western boundary of the Panama Basing
It is probably typical of saddles within most submarine ridges, In
order to determine the mechanisms controlling sediment...

The foraminiferal population of Yaquina Bay was investigated
to attempt a correlation of seasonal changes in the hydrography with
observed changes in the faunal distribution patterns. The results
are based on data from two spatial surveys...

The continental terrace west of Oregon between 43° 50'N and
44° 40' N latitude is 50 to 55 miles wide. It consists of a continental
shelf, 16 to 35 miles wide, and a continental slope, 16 to 37 miles
wide. The eastern portion of the shelf is a...

The volcanic origin of the Samoan archipelago can be explained by one of three models, specifically, by a hot spot forming over a mantle plume, by lithospheric extension resulting from complex subduction tectonics in the region, or by a...

We present an inverse modeling framework designed to constrain CO2 budgets at regional scales. The approach captures atmospheric transport processes in high spatiotemporal resolution by coupling a mesoscale model with Lagrangian Stochastic...

The spatial variability of turbulence and surface heat flux are examined for the case of small air-surface temperature difference and modest sea-surface temperature variability. As a result of nonlinearities in the bulk formula, the heterogeneity...

The Geochemical Ocean Sections Study (GEOSECS) program has carried
out an intensive study of physical and chemical parameters in the
Pacific and Atlantic Ocean. As a result, an enormous collection of high
quality data has been amassed for these...

In the equatorial Pacific Ocean, earthquakes are used as an indicator of tectonic stress
for normal faults in the Galapagos Spreading Center, transform faults along the East
Pacific Rise and thrust faults in the Middle American subduction zone....

Eleven cruises were conducted on the Oregon continental slope
from April 1973 to March 1975 to assess the biology and ecology of
the Tanner crab, Chionoecetes tanneri Rathbun. Bathymetric and seasonal
analysis of the distribution of adult Tanner...

Detailed bathymetric survey data were collected along the Peruvian
continental margin and were compiled by the author and other
investigators to construct a new bathymetric map for the area between
6° to 18°S latitude. Based on this map and...

Specimens of Citharichthys stigmaeus, the speckled sanddab,
were taken from Yaquina Bay, Newport, Oregon and exposed for
eight days to dissolved measured concentrations ranging from 2.9
μg/l to 190 μg/1 of the polychlorinated biphenyl, Aroclor®...

Natural radionuclides may be indicators for dense mineral
placers along marine shorelines. Relict beach and river deposits
occur in continental shelf sediments. These deposits result from the
reworking of beach sands by wave action during the...

During eleven cruises conducted off the Oregon continental
slope from April 1973 to March 1975, approximately 1600 specimens
of the majid crab Chionoecetes tanneri Rathbun were collected.
A time sequence of size frequency histograms and bivariate...

Two beaches with significant differences in grain size and thus in
beach profile morphology and response to wave conditions were studied on
the Oregon coast. Gleneden Beach, just south of Siletz Spit and Lincoln
City, has a median grain size of...
