Using the hydrographic data collected by the ACONA from June
1961 to May 1963, the Oregon coastal front has been examined. Representative
sigma-t surfaces were chosen to delineate the front, and
changes in position of these surfaces with time were used to obtain
zonal flow rates for the frontal and...
A long and gradual transition between the summer and winter
oceanic regimes was observed off Oregon during the autumn of 1980.
Hydrographic sections and a single current meter mooring between
August and December show the ocean possessed characteristics during
fall that have not been observed during other seasons: a slow...
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...
The distribution patterns of quartz and opal contents and the distribution
patterns of radiolarian assemblages, in the sediments of the
southeastern Pacific, are largely controlled by both the surface winds
and the mixed-layer oceanic circulation. The distribution pattern of
quartz is related to eolian and ice-rafted transport, as well as...
Data from the Surveyor 1968 Spring cruise were used to study
the vertical distribution of salinity, temperature, dissolved oxygen,
apparent oxygen utilization, pH, alkalinity, specific alkalinity and
percent saturation of calcite in two sections, one along 162°W from
35°N to 45°N and the other along 180°W from 35°N to 50°N....
A total of 57 core top samples from the Panama Basin were
used in a quantitative study of complete radiolarian thanatocoenoses
to determine whether surface oceanographic conditions are reflected
in the microplankton faunas deposited onto and buried in the sea floor.
Information obtained from this study was used to resolve...
