We present an atmospheric inverse modeling framework to constrain terrestrial biosphere CO₂ exchange processes at subregional scales. The model is operated at very high spatial and temporal resolution, using the state of Oregon in the northwestern...

Shallow cumulus convection evaporates stratocumulus clouds in the atmospheric boundary layer. The effect of shallow convection on the large-scale climate of the eastern tropical Pacific is investigated with a coupled ocean-atmosphere model by...

Observations of wind, currents, sea level and hydrography
obtained during the 1972 Coastal Upwelling Experiment (CUE-I) are
described. Only phenomena with periods longer than a day are considered.
One section describes the changes observed during...

In this study methods were developed for the prediction of wave
conditions that are hazardous to navigation at river entrances, with
emphasis on applicability to the Columbia River. There are two basic
components to the prediction system: (1) a...

A detailed study of iron concentrations measured by the reducible,
reactive ferrous, and extractable methods was conducted in Auke Bay,
Alaska during June 1973 and in Hood Canal, Washington during October
1973 and April 1974. The concentrations by...

An ice cover which progrades over a shallow ocean in the form
of an ice front may induce a baroclinic flow in the underlying water,
provided that the brine excluded from the freezing surface layer is
mixed rapidly through out the underlying water...

Large-volume (20-liter) bioassays were carried out in order to
assess the effects of major nutrients and micro-nutrients on
natural phytoplankton populations in water collected from a site
close to the mouth of Yaquina Bay, Oregon. Seven...

The Carnegie Ridge is a linear, aseismic, submarine ridge
lying between the Galapagos Islands and the coast of South America.
A 2300 meter deep saddle near 86°W. longitude divides the ridge into
western and eastern segments. Surface ship, near...

The thermal regime of a postulated descending lithospheric slab
is calculated. The gravity anomaly associated with such a structure
is large in amplitude and long in wavelengh. Observed free-air
gravity anomalies in the Pacific Northwest do not...

Short-term changes in the distribution, surface to 10 meters, of
phytoplankton-associated trace metals (Fe, Mn, Cr, Zn, Co, Ni, and
Cu) were studied in the near-shore waters off Humboldt Bay,
California, through the summer of 1971. The depth...

Siletz Bay is a drowned river valley filled with Holocene alluvial
and estuarine sediments and is separated from the ocean by a sand
spit 3.8 km in length. Since the area was settled by white man in the
1890's, the bay has apparently experienced...

Natural populations of phytoplankton from Yaquina Bay, Oregon,
were incubated in large polyethelene bags in- situ, with and without
the natural assemblage of zooplankton. Samples were taken daily for
two weeks in April, 1974. The biomass of...

As ocean ecosystems continue to deteriorate in the face of human induced pressures,
marine management professionals are increasingly being urged to predict the impacts of
various activities on ocean ecosystems. Many ecosystem interactions are...

Theoretical breaking criteria for progressive surface gravity
waves are examined, and laboratory and field experiments concerned
with breaking waves are reviewed with respect to the testing of these
breaking criteria. The measurements of Komar and...

Geothermal resources are characterized by a very low electrical
resistivity of the reservoir formations. The application of electrical
methods in the reconnaissance type exploration for such resources is
discussed. It is concluded that the...

A chemostatic system was developed for the long term studies
of population dynamics of chain forming diatoms. Vessel volume
rather than flow rate was varied in these systems to obtain different
growth rates at steady state in systems with an equal...

The one-dimensional numerical model developed by Carl R.
Goodwin is applied to the Siuslaw estuary. Vertical displacement,
horizontal velocity and flow of the water as a function of time and
distance from the mouth given by the model are compared...

The portion of the East Pacific Rise (EPR) between 5° and 12°S
can be subdivided into three areas by fracture zones that offset the
rise axis at about 6.5°S and 9°S. In all three regions, the spreading
axis of the EPR is defined by a topographic...

Easter Island and Sala y Gomez are part of the Sala y Gomez
Ridge, a broad band of high topography and scattered seamounts
extending ESE from the East Pacific Rise. It has been proposed that
the Sala y Gomez Ridge results from the movement of the...

In the upper estuary of Yaquina Bay, Oregon, there is an annual
population explosion of Acartia tonsa, (Dana) a calanoid copepod,
during the months of July, August and September, followed by a rapid
decline to virtual extinction in November. The...
