Observations of the hydrographic regime over the continental shelf off Oregon from the R/V Yaquina during the summer of 1972 showed the presence of an alongshore, subsurface ribbon of relatively cool water. Its properties and its evolution during the 1972 season are described. Examination of earlier observations showed that evidence...
By implementing a series of mass-conserving nested high-resolution models down to approximately 1 km resolution that have realistic bathymetry, coastline, wind forcing and river run-off, the winter 1996-1997 shelf flow near Cape Mendocino, California, is simulated and compared with available observations from the Strata Formation on Margins (STRATAFORM) marine geology...
In this report we will present vertical sections of temperature, salinity and sigma-t from both CTD and bottle casts made on legs 1-5 of the R/V Eastward during JASON, and from CTD casts made on legs 1, 2 and 4 of the R/V Melville and legs .2 and 4 of...
Two mesoscale surveys were conducted (in July 1981 and July 1982) near Point Arena, California, to
determine the structure and circulation associated with tongues of cold surface water extending seaward
from the coastal zone. Both surveys were designed at sea on the basis of available satellite IR data, and
each...
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...
Repeated mesoscale surveys of a 40-km-wide, 100-km-long, coastal region near Point Arena, California, were conducted during the upwelling season (April-August) in 1981 and 1982. Each survey included conventional conductivity-temperature-depth casts at standard locations over the continental shelf and slope between 38°N and 39°10'N, and continuous operation of a Doppler acoustic...
Hydrographic observations were made over the continental shelf and slope off Oregon during the 1973 Coastal Upwelling Experiment (CUE-II) from three ships: R/V OCEANOGRAPHER, R/V THOMAS G. THOMPSON, and R/V YAQUINA. This report contains the observations made on four YAQUINA cruises between June and August 1973 (Table I). Observations were...
Current and conductivity, temperature, and depth (CTD) measurements were made over the Oregon
shelf near 43°N between February 1981 and April 1984 as part of a large-scale west coast shelf experiment
(SuperCODE). The data set includes a nearly continuous record of current velocity and temperature
over the continental shelf off...
Observed changes in the nutrient levels in the halocline of the California Current during 2002 indicated a natural eutrophication that was accompanied by increased chlorophyll and oxygen in surface water. Decreased oxygen in the lower water column over the shelf indicated that much of the phytoplankton production was respired rather...
