Abstract: Using velocity and temperature profile surveys collected beside a seamount, the dependence of the energy ratio PE/KE on the aspect ratio (NkH/fkz)2 is compared with theoretical relations for linear internal waves and ...

Abstract: nternal-wave-driven dissipation rates ε and diapycnal diffusivities K are inferred globally using a finescale parameterization based on vertical strain applied to ~30,000 hydrographic casts. Global dissipations are 2.0 ± ...

Abstract: Velocity and temperature profiles collected in warm-core ring 82-I in January 1983 are used to describe the mean and fluctuating fields of the ring. The ring was relatively small, containing no Sargasso See water. Its ...

Abstract: An approximate dispersion relation for near-inertial internal waves propagating in geostrophic shear is formulated that includes straining by the mean flow shear. Near-inertial and geostrophic motions have similar horizontal ...

Abstract: In the decade or so below the Ozmidov wavenumber (N3/ε)1/2, that is, on scales between those attributed to internal gravity waves and isotropic turbulence, ocean and atmosphere measurements consistently find k1/3 horizontal ...

Abstract: A transect of velocity profiles across Gulf Stream warm-core ring 82-B shows that the thermostad contained virtually no vertical shear. Enhanced downward-propagating near-inertial wave shear was present at the base of the ...

Abstract: The spectral transfer of internal wave energy toward high vertical wavenumber kz and turbulence production ε is examined by ray tracing small-scale test waves in a canonical Garrett and Munk background wave field. Unlike ...

Abstract: Small-scale internal waves are numerically ray-traced through random 3D Garrett and Munk internal wave backgrounds. Past ray-tracing investigations of the transfer of internal wave energy toward small scales have considered ...

Abstract: Regions of negative vorticity are observed to trap and amplify near-inertial internal waves, which are sources of turbulent mixing 10?100 times higher than typically found in the stratified ocean interior. Because these ...

Abstract: Equatorial deep jets are an unsolved mystery of the equatorial oceans. These alternating zonal currents appear steady over time spans of years, but no postulated energy source has proven plausible, and elevated turbulent ...
