RISThe Poisson Link Between Internal Wave and Dissipation Scales in the Thermocline Part II. Internal Waves, Overturns, and the Energy Cascade
Publisher: American Meteorological Society
Abstract: The irregular nature of vertical profiles of density in the thermocline appears well described by a Poisson process over vertical scales 2-200 m. To what extent does this view of the thermocline conflict with established ...
Vortical and Internal Wave Shear and Strain
Publisher: American Meteorological Society
Abstract: epth?time records of isopycnal vertical strain have been collected from intensive CTD profiling programs on the research platform (R/P) Floating Instrument Platform (FLIP). The associated vertical wavenumber frequency ...
Observations of the Near-Surface Internal Wavefield
Publisher: American Meteorological Society
Abstract: During January 1977 a cruise was conducted off the California coast on the Research Platform FLIP. Repeated temperature profiling devices were used to sense the internal wavefield in the top 400 m of the sea. From a sequence ...
The Wavenumber–Frequency Spectrum of Vortical and Internal-Wave Shear in the Western Arctic Ocean
Publisher: American Meteorological Society
Abstract: Upper-ocean velocity and shear data were obtained from Doppler sonars operated at the Surface Heat Budget of the Arctic Ocean (SHEBA) ice camp during the camp?s year-long drift across the western Arctic Ocean. These are ...
Observations of Strongly Nonlinear Internal Motion in the Open Sea Using a Range-Gated Doppler Sonar
Publisher: American Meteorological Society
Abstract: A Doppler sonar has been developed at the Marine Physical Laboratory for the remote measurement of the upper ocean velocity field. The sonar transmits a 1° beam at 87.5 kHz, with 3 KW peak power. The sound scatters off ...
A Wavenumber-Frequency Spectrum of Upper Ocean Shear
Publisher: American Meteorological Society
Abstract: In May 1980 an 18-day sequence of oceanic velocity profiles was obtained off the coast of Southern California. The measurements were made using a pair of Doppler sonars mounted on the research platform FLIP and angled ...
Internal Solitary Waves in the Warm Pool of the Western Equatorial Pacific
Publisher: American Meteorological Society
Abstract: During the spring tides of late November 1992, early January and early February 1993, solitary internal wave packets were observed at 2°S, 156°15?E in the western equatorial Pacific. Apparently generated in the Nuguria ...
Near-Inertial Wave Propagation in the Western Arctic
Publisher: American Meteorological Society
Abstract: From October 1997 through October 1998, the Surface Heat Budget of the Arctic (SHEBA) ice camp drifted across the western Arctic Ocean, from the central Canada Basin over the Northwind Ridge and across the Chukchi Cap. ...
The Poisson Link Between Internal Wave and Dissipation Scales in the Thermocline Part I. Probability Density Functions and the Poisson Modeling of Vertical Strain
Publisher: American Meteorological Society
Abstract: The irregular nature of vertical density profiles is a ubiquitous characteristic of the ocean thermocline. This distortion can be quantified by tracking a set of constant-density (isopycnal) surfaces over time. Examination ...
Advection, Phase Distortion, and the Frequency Spectrum of Finescale Fields in the Sea
Publisher: American Meteorological Society
Abstract: Continuous depth?time measurements of upper-ocean velocity are used to estimate the wavenumber?frequency spectrum of shear. A fundamental characteristic of these spectra is that the frequency bandwidth increases linearly ...
