Intensified Diapycnal Mixing in the Midlatitude Western Boundary Currents

The wind work on oceanic near-inertial motions is suggested to play an important role in furnishing the diapycnal mixing in the deep ocean which affects the uptake of heat and carbon by the ocean as well as climate changes. However, it remains a puzzle where and through which route the near-inertial energy penetrates into the deep ocean. Using the measurements collected in the Kuroshio extensio...

Topographic enhancement of vertical turbulent mixing in the Southern Ocean

It is an open question whether turbulent mixing across density surfaces is sufficiently large to play a dominant role in closing the deep branch of the ocean meridional overturning circulation. The diapycnal and isopycnal mixing experiment in the Southern Ocean found the turbulent diffusivity inferred from the vertical spreading of a tracer to be an order of magnitude larger than that inferred ...

Widespread intense turbulent mixing in the Southern Ocean.

Observations of internal wave velocity fluctuations show that enhanced turbulent mixing over rough topography in the Southern Ocean is remarkably intense and widespread. Mixing rates exceeding background values by a factor of 10 to 1000 are common above complex bathymetry over a distance of 2000 to 3000 kilometers at depths greater than 500 to 1000 meters. This suggests that turbulent mixing in...

Mixing at the external boundary of a submerged turbulent jet.

We study experimentally and theoretically mixing at the external boundary of a submerged turbulent jet. In the experimental study we use particle image velocimetry and an image processing technique based on the analysis of the intensity of the Mie scattering to determine the spatial distribution of tracer particles. An air jet is seeded with the incense smoke particles, which are characterized ...

Turbulent Mixing in Oceanic Surface and Benthic Boundary Layers

The objectives of the specific effort being reported are to improve the fundamental knowledge of turbulent mixing and diffusion processes occurring in oceanic boundary layers, with special emphases on the surface mixed layer and the wave-current boundary layer in coastal oceans. In the studies of surface mixed layers, the focus is on the penetration of a mixed layer (say, driven by the wind) in...
