Solar radiation intensities, incident to the sea surface off the Oregon
coast, are measured and compared. Simplification of some physical
and biological problems can be anticipated if the average radiation
received over a broad segment of ocean can be accurately indicated
by the amount recorded at the land station.

An intensive chemical investigation, that includes the
determinations of salinity, oxygen, nutrients, pH, alkalinity, and
total carbon dioxide of the Columbia River plume off the Oregon
coast in July 1967 shows the following unique features:
1. Along the axis of the river plume both the salinity minimum and
temperature maximum...
The relationship between sea level and wind stress in a region of
known upwelling was studied for an eleven-month period during
1933-34.
Sea level data, obtained from observations taken by the Coast and
Geodetic Survey, were processed to remove astronomic tidal constituents
and inverted barometer effect. Regression analysis was used...
A liquid-extraction procedure for the concentration of zinc in
sea water was developed. The metal ion in sea water was chelated
with sodium diethyldithiocarbamate and extracted into an organic
solvent, methylisobutylketone, at the normal pH of sea water. A
back-extraction into HCl followed, providing a concentration of 30X
for the...
In situ salinity, turbidity and temperature were measured at discrete depths and water samples for radioanalysis were simultaneously collected in the Columbia River Estuary using a specially designed instrument package. Particulate radioactivity was concentrated by filtration and the dissolved radioactivity by evaporation or ferric oxide bulk precipitation. Radioanalysis was by...
