A study was done on the zoogeography of species of oceanic
shrimp in the North Pacific from 22°N to 56°N and from 124°W to
145°E, using samples of shrimp collected from 1954 to 1969. These
collections were made during the following cruises: John R. Manning
Cruise 22, and the Hugh...
Questions relating to economic performance, biological conservation and variation in resource abundance and harvest of ocean shrimp have led to increasing pressure for management action. Developing effective management policies for this highly variable resource requires a comprehensive understanding of the fishery and marine processes. Important factors in understanding the fishery...
Moored instrument records, drogue displacements, and hydrographic
observations are used in describing the coastal currents and
upwelling off Peru. The data were obtained over the continental shelf
near 15°S. during a two week study in late March and early April of
1969.
First order statistics and graphical representations of current...
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...
Direct measurements of vertical water motions were made in
the Oregon coastal region during the 1972 summer upwelling season.
The instruments used were the Webb-Voorhis vertical current meters
which are freely drifting neutrally buoyant floats capable of sensing
vertical motion. It was found that in the region studied, water tended...
Nearly three months of current meter records from five moorings off
the Oregon coast taken between October 1977 and January 1978 were analyzed
for near-inertial motions. The moorings were located from the midshelf
out to the foot of the continental slope, spanning the continental
margin. All but two of the...
