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...
Calcareous sediments containing a large percentage of foraminiferal
microskeletal tests were taken from sites in the Panama Basin
and subjected to an investigation to determine the consolidation characteristics
of this type of soil. The consolidation-stress curves and
the time rate of consolidation curves in particular were investigated
in this study....
Examination of polished sections of manganese micronodules
from metalliferous sediments from the Bauer Deep reveals sequences
of ferromanganese deposition which are consistent for micronodules
from a single sediment sample and imply a common depositional
history for members of such assemblages. The relatively simple
'stratigraphy' of manganese micronodules, as compared to...
