A criterion is defined to compare seasonal ice coverage in the Greenland Sea for the years 1900-57, and the areal coverage is graphed using the 1898-1913 average as a standard. The factors wielding possible influence ...

Realistic assessment of the vertical distribution of clouds, particularly the occurrence of multi-layered systems, is critical for accurate calculations of radiative transfer in general circulation models. Such informa ...

Oregon's estuaries have been significantly altered by human activity, so that many former tidal wetlands no longer provide the functions, such as fish and wildlife habitat, erosion protection from storms, and water quali ...

Tropical instability waves (TIWs) are prominent seasonal features in both the equatorial Pacific and Atlantic Oceans. This work quantifies their role in modulating the distributions of nutrients and phytoplankton biomass ...

Data from Section 404 permits, which were issued in California from January 1971 through November 1987 and required compensatory mitigation, were compiled and analyzed to determine patterns and trends in permitting activ ...

Improvements have been made to the spatial coherence method for automatically determining cloud-free ocean radiances in satellite imagery by incorporating the spectral signatures of reflecting surfaces. The spatial coh ...

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 Apri ...

This thesis investigates the influence of early diagenesis on trace metal and molybdenum isotope behavior in marine and lacustrine environments. Chapter one is a synthesis of previous research in all the marine environ ...
