We use the position fixes and temperature readings from 56 Tristar-II mixed-layer drifters, in conjunction with advanced very high resolution radiometer images, to provide a description of the mesoscale variability of the flows associated with cold-water filaments in the California Current system off northern California in July 1988. We find...
A Lagrangian drifter was deployed in a cold filament off northern California as part of the Coastal Transition Zone program. The drifter was equipped with an optical package (consisting of a spectroradiometer, a fluorometer, and a beam transmissometer) suspended at 8.5-m depth and a water sampler suspended at 16.3-m depth....
A new method is presented for estimating the vertical turbulent heat flux at the bottom of the daily mixed layer from the temperature data in the mixed layer and net solar irradiance data at the sea surface. We assume that fluctuations in the divergence of advective heat flux have longer...
In this paper, we evaluate the temporal and horizontal resolution of geostrophic
surface velocities calculated from TOPEX satellite altimeter heights. Moored velocities
(from vector-averaging current meters and an acoustic Doppler current profiler) at depths
below the Ekman layer are used to estimate the temporal evolution and accuracy of
altimeter geostrophic...
Data from the Coastal Transition Zone (CTZ) experiment are used to describe the velocity fields and water properties associate with cold filaments in the California Current. Combined with previous field surveys and satellite imagery, these show seasonal variability with maximum dynamic height ranges and velocities in summer and minimum values...
During the summers of 1987 and 1988, 77 near-surface satellite-tracked drifters were deployed in or near cold filaments near Point Arena, California (39ºN), and tracked for up to 6 months as part of the Coastal Transition Zone (CTZ) program. The drifters had large drogues centered at 15 m, and the...
The FRONTS-80 experiment is a joint investigation supported by the
Office of Naval Research (ONR) as the lead agency with additional contributions
from the National Oceanic and Atmospheric Administration (NOAA),
the National Space Administration (NASA), the U.S. Navy and the Canadian
Forces. Support from these agencies is gratefully acknowledged. We...
This report presents CTD observations of temperature and salinity as a function of hydrostatic pressure in the Kuroshio Extension in May 1981. Lowerings were made from the surface to the bottom along 152°E about every 30 nautical miles between 29°N and 41°N. Identical sections were made in July 1980 and...
Between January 1973 and May 1975, the National Science Foundation sponsored a cooperative field program of direct measurements of circulation on the continental shelf of the west coast of the Florida peninsula. With a variety of instruments, records of ocean currents, bottom pressure,
coastal sea level and winds over the...
A summary of the observations taken from moored stations and hydrographic surveys in POLYMODE Array III Cluster C is presented. Currents and water temperatures were measured at various depths, including: 150, 225, 300, 500, 750, 1500, 2500, and 4000 meters.
Hydrographic surveys were made during the deployment and recovery cruises....
