Allocentrotus fragilis (Jackson) was obtained from six stations
at depths of 100 to 1260 m on the continental shelf and upper slope off
Newport, Oregon.
Ages and growth rates of A. fragilis were determined by two
methods: 1) A procedure was...

The influence of boundary layer pumping on an externally-forced
synoptic-scale flow is examined. The results follow earlier theories of
stratified incompressible Boussinesq flow. These theories state that
the spin-down time scale and the...

The seasonal variation of wind speed fluctuations is studied at
four locations in The Dalles area of the Columbia River Gorge.
Three of the sites are located in or near the valley floor while the
fourth site is on top of a 900 m (3000 ft) ridge...

A radiation model was developed for retrieving cloud visible optical depth,
droplet effective radius, and cloud top emission temperature using AVHRR satellite
observations at 0.63, 3.7, and 11 μm. The model was used to determine the sensitivity
of...

Illite, chlorite, montmorillonite and kaolinite, as well as
natural marine sediments and mixtures of the standards were subjected
to density separation by centrifugation in a linear heavy-liquid
gradient.
The density layers yielded by...

Samples of benthic organisms off the coast of Oregon, taken
from depths varying from 50 to 2900 meters, have been analyzed in
terms of diversity at a given station, and similarity and ecological
distance to other stations. Estimates of epifauna...

Sea level and current observations made over the Oregon
continental shelf exhibit wavelike characteristics in a frequency band
from approximately 0.15 to 0.45 cpd. In a narrow band around
0.22 cpd the current-sea level relationship is consistent...

Heavy minerals can contain potentially economic amounts of
metals as both matrix and trace constituents. Such minerals appear
as unconsolidated black sands on the continental shelf off southwest
Oregon and along the Oregon coast. Two diverse...

The distribution of surface sediments on the northern Oregon
continental shell is characterized by a nearshore sandy facies and an
outer shelf muddy facies, separated by a mid-shelf zone of mixed
sand and mud. Currents which have been measured at...

Measurements of the fluctuations of humidity, temperature
and velocity were made in the marine boundary layer. The humidity
fluctuations were measured with a Lyman-alpha humidiometer.
Temperature fluctuations were measured with a dry thermocouple...

Climate models predict a decrease in oceanic dissolved oxygen and a thickening of the oxygen minimum zone, associated with global warming. Comprehensive observational analyses of oxygen decline are challenging, given generally sparse historical...

The length of time that atmospheric pollutants released from low-level
sources in the midwestern United States can expect to remain in
the atmosphere is discussed. The pollution is assumed to be removed
from the atmosphere by dry deposition and...

The Columbia River plume region was investigated during the
period of 20 June to 3 July, 1968 by light scattering measurements
and standard hydrographic station observations. The Columbia
River plume was traced by the light scattering particles of...

Polychaete annelids from 48 benthic samples containing over
2000 specimens were identified. Samples were taken with either an
anchor dredge or an anchor-box dredge from a 15 station transect
(44° 39. 1'N) that ranges from 800 to 2900 meters in...

The quantification and description of sea surface temperature (SST) is critically important because it can influence the distribution, migration, and invasion of marine species; furthermore, SSTs are expected to be affected by climate change. To...

Of the common adult lanternfishes found off Oregon, two
species have fat-invested swimbladders (Stenobrachius
leucopsarus Eigenmann and Eigenmann 1890 and Stenobrachius
nannochir Gilbert 1891), two species have reduced swimbladders
(Lampanyctus...

A graphical method, based on a set of acid-base titrations, is
presented for the determination of the carbon dioxide speciation in
natural solutions. The application of this method, in conjunction
with measurements of the partial pressure of...

Magnetic, gravity and bathymetry data were collected on an extended
cruise of the R/V Yaquina in 1969. The last set of data was obtained
from those track lines leaving the Panama Basin. The area
covered is mainly the Cocos plate (Molnar and Sykes,...

A cruise of the R/V Yaquina off Oregon during June and July of
1968 provided data for a study of the relationships of hydrographic
and chemical parameters to estimates of biological activity. The
emphasis was on carbon and nitrogen reservoirs....
