Euphausia pacifica lives for a period of approximately one year,
disappearing from the catches at a size of about 22-24 mm. Spawning,
which occurs mainly inshore, extends from June through December
but generally is most prominent in the autumn...

Spectral analysis was used to investigate semidaily mean sea
levels and atmospheric pressures at San Francisco, California,
Coos Bay, Oregon, and Tofino, British Columbia, in the frequency
band 0 to 0.5 cpd. Cross spectral analysis of semidaily...

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...

Investigation was made into the influence of changing light
intensity on the organic and elemental composition of two species of
marine diatoms, Ditylum brightwellii and Skeletonema costatum.
Analysis was made of the relative changes in soluble...

The nature of the bioluminescence of Gonyaulax catenella is
similar to that observed for other dinoflagellates in culture, showing
photoperiod-entrained rhythms of luminescence and stimulability
with relatively constant luminescent capacity during...

The electrical conductivity of the pyromagmas from the Northeast
Crater of Mount Etna, Sicily was measured over the temperature
range 1032°C to 1071°C and over the frequency range 1 kHz to
400 kHz. Measurements were made using a four-terminal...

The stoichiometric model of organic decomposition in seawater
(Redfield, Ketchum, and Richards, 1963) was used to describe the
oceanic distribution of total carbon dioxide. It was assumed that the
concentration of total carbon dioxide was the sum...

In order to understand the atmospheric branch of the earth's
hydrologic cycle on the global scale, an atmospheric moisture balance
is diagnostically analyzed from the January and July data of the OSU
atmospheric general circulation model, which...

The association of frontal formation, development, and movement with
large scale baroclinity is well documented. This investigation
deals with the mean large-scale baroclinic zones near the Asian East
Coast for the last two weeks of February 1975....

We examined the relationships between large wood (LW) export and precipitation patterns and intensity by analyzing the data on the annual volume of LW removed from 42 reservoirs and the daily precipitation at or near the reservoir sites. We also...

The four components of the long-term annual mean net surface heating of the tropical Pacific Ocean between 30°N and 40°S are calculated and portrayed. These flux elements were derived by using the bulk formulas and about 5 million marine weather...

In this article the authors examine the kinematics and dynamics of the seasonal cycle in the western Indian Ocean in an eddy-permitting global simulation [Parallel Ocean Circulation Model, model run 4C (POCM-4C)]. Seasonal changes of the transport...

We evaluate the method of estimating sea surface velocities from sequences of AVHRR and CZCS images using the maximum cross-correlation (MCC) technique. A set of synthetic images is created by advecting an AVHRR-SST field with a QG model velocity...

High resolution data of moisture, temperature and wind velocity
collected by aircraft during the 1975 Air Mass Transformation
Experiment (ANTEX '75) provide information for detailed investigations
of the phenomena occurring at the top of a...

Nitrate reductase is known to be the enzyme regulating the
reduction of nitrate to nitrite in plants. This reduction is the first
and rate-limiting step in the transformation of inorganic nitrate to
a cellular nitrogen form. Since this reduction...

Current observations were obtained at three locations forming
a cross section along 70°34'W longitude in Long Island Sound. Fifteen
days of data were selected from each series so that nearly
simultaneous observations were used in the analysis....

The Risø data were analyzed for variations in the surface roughness
lengths. The method of analysis was tested on the Wangara data
and proved satisfactory at this homogeneous site.
Annual mean surface roughness lengths were determined for
three...

Surface meteorological data collected at a mesonetwork in
Colorado during the 1973 National Hail Research Experiment were
analyzed to see if a diurnal oscillation of boundary layer wind exists
and also to determine the mechanism that drives the...

A shallow convection scheme is derived from several data sets
(BOMEX, GATE, AMTEX, BLX83) and developed for the OSU 1-D boundary
layer model. Results of the model structure and characteristics of
the saturation point (SP) profile are compared...

Relationships among the surface wind, horizontal synoptic-scale
pressure gradient and topography are studied in the Willamette Valley
in western Oregon. Terrain features alter the standard surface wind-pressure
gradient relationship such that the...

A time dependent model of the shallow, tropical convective boundary layer is
developed and tested. To simplify the treatment of thermodynamic processes and
return to first principles of physics, conserved quantities of entropy and total
water...

Fine and coarse particles were collected for eight weeks during the
summer of 1991, at a coastal site (Yaquina Head) and a non-industrial site
(Corvallis) in Western Oregon to characterize the aerosol composition and
evaluate whether the sites are...

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...

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...

Three-dimensional gravity analysis is the process of removing the predictable
components from the free-air gravity anomalies and has proven to be useful for
interpreting the subsurface structures and active processes at mid-ocean ridges. The...
