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...
The sea as a dynamic conducting medium interacts continually
with the earth' s magnetic field. The physical principles underlying
this interaction are reviewed. These results are applied to the
particular problem of towed electrodes at the sea surface. Data
using this method are then shown to be sensitive to stability...
Sea level and current observations made over the Oregon
continental shelf exhibit wavelike characteristics in a frequency band
from approximately 0.15 to 0.45 cpd. In a narrow band around
0.22 cpd the current-sea level relationship is consistent with the
predicted values for the first mode of Robinson's continental shelf
waves....
The perturbation method is applied to solve two numerical
problems in the earth sciences, viz., (l)the computation of deep sea
currents in the coastal region of the northeast Pacific and (2) the
interpretation of D.C. conduction data in exploration geophysics.
The perturbation method is largely equivalent to the method of...
Observations of wind, currents, sea level and hydrography
obtained during the 1972 Coastal Upwelling Experiment (CUE-I) are
described. Only phenomena with periods longer than a day are considered.
One section describes the changes observed during a period
of variable winds in early July 1972. Another describes a ribbon of
relatively...
Hydrographic data and drogue observations were used to describe
the circulation and water masses in the upper 500 meters of
the region of the entrance to the Gulf of California in the early spring
of 1970.
The thermohaline structure of the water and the general circulation
in the vicinity of...
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...
We investigated sea level fluctuations at seven locations from San Francisco to Torino, British
Columbia, during a 2-year period beginning in August 1973. Using overlapping 2-month periods, we
found the alongshore correlation to vary with time and with location along the coast. In winter the
fluctuatioans are correlated along the...
Current meter moorings maintained over the Oregon continental shelf in 1973 and 1975 clearly show the difference between winter and spring oceanographic regimes and the rapid transition between the regimes. In winter the mean alongshore current is northward at all depths and strongest near shore; there is no mean vertical...
