Signatures of Mixing from the Bermuda Slope, the Sargasso Sea and the Gulf Stream
Publisher: American Meteorological Society
Abstract: 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 with regions of ...
Observations of Hurricane-Generated, Near-Inertial Slope Modes
Publisher: American Meteorological Society
Abstract: Velocity Profiles and current meter measurements taken near Site D(39°10?N, 70°00?W) on the continental rise south of New England are used to study the variability of the near-inertial wave field along a sloping bottom. ...
The Subthermocline Lens D1. Part II: Kinematics and Dynamics
Publisher: American Meteorological Society
Abstract: The dynamics of a subthermocline lens observed during the POLYMODE Local Dynamics Experiment are examined using density data and measurements of the velocity field obtained by an absolute velocity profiler. It is shown ...
The Subthermocline Lens D1. Part I: Description of Water Properties and Velocity Profiles
Publisher: American Meteorological Society
Abstract: One remarkable result of the Local Dynamics Experiment in POLYMODE is the discovery of a large number of small energetic eddies. Using CTD data, SOFAR float tracks, and profiles of absolute velocity, we describe one of ...
Varieties of Fully Resolved Spectra of Vertical Shear
Publisher: American Meteorological Society
Abstract: The Multi-Scale profiler (MSP) resolves shear between vertical wavenumbers of 0.01 cpm and the viscous cutoff of small-scale turbulence. Observations from five sites reveal varied spectral shapes and amplitudes. Spectral ...
Surface Mixing Layers in the Sargasso Sea
Publisher: American Meteorological Society
Abstract: 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 forcing. Two frontal ...
Resolving Oceanic Shear and Velocity with the Multi-Scale Profiler
Publisher: American Meteorological Society
Abstract: The Multi-Scale Profiler (MSP), a freely falling dropsonde, has been used over the past 12 years to measure oceanic shear variance. Complete resolution of oceanic shear spectra is achieved by combining the measurements of ...
Inferring Density from Temperature via a Density-Ratio Relation
Publisher: American Meteorological Society
Abstract: A method is presented for determining salinity and density from temperature data in conjunction with historical or contemporaneous (but not collocated) CTD observations. The horizontal density ratio r(z) is determined from ...
A Composite Spectrum of Vertical Shear in the Upper Ocean
Publisher: American Meteorological Society
Abstract: Results from three separate velocity profilers operated nearly simultaneously in the northwest Atlantic in 1975 are used to form a composite shear spectrum over vertical wavelengths from 100 m down to a few centimeters. ...
