Profile of an Isopycnal Surface in the Main Thermocline of the Sargasso Sea
Isopycnal Surface Main Thermocline Sargasso Sea
2009/4/2
The vertical displacement and slope of an isopycnal surface (by which is meant a density surface of constant σt) are described spatially. The data were acquired by towing pressure, temperature and con...
Gulf Stream Eddies：Recent Observations in the Western Sargasso Sea
Gulf Stream Eddies Western Sargasso Sea
2009/4/2
A cyclonic Gulf Stream eddy was observed in the western Sargasso Sea by satellite infrared measurements and later confirmed by ship measurements. Fourteen months of observations indicate that the eddy...
A Comparison of Cyclonic Ring Structures in the Northern Sargasso Sea
Cyclonic Ring Structures Northern Sargasso Sea
2009/2/23
Field observations provide a data base that supports a comparison of ring structures in terms of the background Sargasso Sea environment. Five ring surveys, three from the 1967 sequence, a big baby ri...
Temporal Variations in Regional Models of the Sargasso Sea from GEOS-3 Altimetry
sea surface height Regional Models Temporal Variations
2009/2/16
The dense coverage of short-pulse mode GEOS-3 altimeter data in the western North Atlantic provides a basis for studying time variations in sea surface height (SSH) in the Sargasso Sea. Two techniques...
Signatures of Mixing from the Bermuda Slope, the Sargasso Sea and the Gulf Stream
Mixing Sargasso Sea Bermuda Slope Gulf Stream
2009/2/16
Nearly simultaneous profiles of temperature microstructure and velocity shear were made adjacent to the island of Bermuda. Profiles with elevated microstructure levels were found in close association ...
Observations of turbulent energy dissipation rate in the deep surface mixed layer at a mid-Sargasso site are presented: two occupations of this site include a large range of local meteorological forc...
Upper Ocean Thermal Variability in the Sargasso Sea July 1977–July 1978：The POLYMODE XBT Program
surface temperatures Upper Ocean Thermal Variability POLYMODE XBT Program
2009/2/5
We discuss the upper ocean mesoscale temperature variability field as sampled by XBT's in the joint US-USSR POLYMODE Synoptic Experiment during July 1977 to July 1978. There is a “background” persiste...
Wind Forced Internal Waves in the North Pacific and Sargasso Sea
Internal Waves Sargasso Sea North Pacific
2009/1/20
The three-dimensional structure of the near-inertial frequency internal wave field was measured at two open ocean sites using expendable velocity profilers. Both wave fields appear to be dominantly wi...
A Near-Inertial Internal Wave Spectrum for the Sargasso Sea in Late Summer
Near-Inertial Internal Wave Spectrum Sargasso Sea Late Summer
2009/1/19
Independent estimates of the frequency–wavenumber spectrum of near-inertial waves for the Sargasso Sea in late summer were made using 8 time series of horizontal velocity from a single moored vertical...
Horizontal Variability of Microstructure in the Vicinity of a Sargasso Sea Front
Horizontal Variability Microstructure Sargasso Sea Front
2009/1/12
Temperature microstructure variability has been determined from measurements of electrical conductivity (1.5 cm wavelength resolution) along two depths in the seasonal thermocline of the Sargasso Sea ...
Observations of an Anticyclonic Eddy of 18°C Water in the Sargasso Sea
Anticyclonic Eddy 18°C Water Sargasso Sea
2009/1/12
Observations have been made of a lens of 18°C water in the Sargasso Sea near 30°N, 69°W. The lens was nearly isothermal and isohaline and was embedded in the more typical weakly stratified 18°C water ...
On the Role of Heat Flux in the Gulf Stream-Sargasso Sea Subtropical Gyre System
potential vorticity Heat Flux Gulf Stream-Sargasso Sea Subtropical Gyre System
2009/1/9
In contrast with the traditional view of midlatitude circulation driven by winds in the ocean interior and regulated by friction along the western boundary, it is hypothesized that some control can be...
Variability in the Upper-Ocean Internal Wave Field at a Sargasso Sea Site
Upper-Ocean Sargasso Sea Site Internal Wave Field
2009/1/6
Two 3.5 month time series records of upper-ocean current and density profiles collected in opposite seasons as part of the LOTUS (Long-Term Upper-Ocean Study) project at 34°N, 70°W indicate substantia...
Current Shear–Inertial Wave Interaction in the Sargasso Sea
Acoustic Doppler profiler inertial waves Sargasso Sea
2008/12/27
Acoustic Doppler profiler measurements of inertial waves embedded within the high shell region of a cold core ring in the Sargasso Sea are described. By repeatedly traversing the same point from diffe...
