Batch cultures of Skeletonema costatum were grown under continual
light saturation, with nitrogen nutrients in limiting concentrations.
Population parameters measured included ¹⁴C uptake,
chlorophyll a, particulate carbon and nitrogen, and ammonia, nitrate,
and nitrite, concentrations.
A method was developed for measuring cellular nutrient reservoirs
in laboratory cultures of marine phytoplankton....
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 semi-automated spectral
method for forecasting the significant height and average period...
In January-February 1971 five replicate 0.07 m² Van Veen grabs
were obtained from each of 12 stations in Arthur Harbor and nine Van
Veen grabs were obtained from two stations in nearby Bismark Strait.
The 69 grab samples yielded 78,395 individuals which were separated
into 282 taxa, including 108 species...
Two separate studies on the distribution of gammarid amphipods in the bathyal and abyssal benthic environments demonstrated that different assemblages could be found at a single depth over distances on the order of 100 kilometers. These studies evaluated changes in the species composition and relative abundance of the amphipod assemblage...
Twelve earthquakes off the Oregon and Northern California
coasts were used in this research to study whether faulting associated
with these quakes was of the San Andreas type as observed in
California. The first motions of the incident P and S waves recorded
at various seismic stations in the Pacific...
Starved cells of Ant-300, a psychrophilic marine Vibrio, maintained
binding and transport systems for glutamic acid, arginine, proline, and
leucine. The uptake of these amino acids was inhibited by the uncoupler
2,4-dinitrophenol indicating that an energized membrane was necessary
for binding and was maintined in starved cells. The levels of...
