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...
We sharpen our view of an eastern boundary current region during
the upwelling season through the analysis of several data sets.
We focus on the mesoscale flow field off of northern California,
observed during the Coastal Transition Zone (CTZ) experiment of 1988.
First, we estimate tidal currents in the region...
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...
A method is described for determining the absolute dynamic topography of the sea surface. Using hydrographic and wind data obtained in 1963, the surface topography and the horizontal and vertical mass transports off the southeast Arabian coast during the summer monsoon are calculated. As indicated by the calculations, upwelling occurs...
The physical characteristics of continental shelf waters off
Oregon during late winter and spring of 1975 are described and compared
with observations taken previously during summer. The currents
in winter are barotropic in the monthly means while in summer
the currents are baroclinic. Alongshore current fluctuations on the
time scale...
Spectral analysis was used to investigate semidaily mean sea
levels and atmospheric pressures at San Francisco, California,
Coos Bay, Oregon, and Tofino, British Columbia, in the frequency
band 0 to 0.5 cpd. Cross spectral analysis of semidaily mean sea
levels and atmospheric pressures at the three stations show that the...
A criterion is defined to compare seasonal ice coverage in the
Greenland Sea for the years 1900-57, and the areal coverage is
graphed using the 1898-1913 average as a standard. The factors
wielding possible influence on short-term variations of the ice cover
are examined individually and their relative importance established....
