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...
A simplified autoradiographic method for estimating species-specific
phytoplankton production rates in mixed natural communities
was evaluated in the laboratory and employed in the field. Laboratory
experiments were designed to test the reliability and variability of
the simplified method. Assays of ¹⁴C uptake by liquid scintillation
spectrometry were used to evaluate...
The Geochemical Ocean Sections Study (GEOSECS) program has carried
out an intensive study of physical and chemical parameters in the
Pacific and Atlantic Ocean. As a result, an enormous collection of high
quality data has been amassed for these two oceans. To analyze the
Pacific data, fourteen stations extending from...
Sea level and current data collected near Newport, Oregon are
compared to determine an empirical relationship from which the low
frequency (f < .1 cpd) alongshore current field over the continental
shelf is estimated from observed sea level measurements at the coast.
Regression analysis of the near-surface (20-25 m) currents...
