Global abyssal mixing inferred from lowered ADCP shear and CTD strain profiles / Eric Kunze, Eric Firing, Julia M. Hummon, Teresa K. Chereskin, Andreas M. Thurnherr.

Title: Global abyssal mixing inferred from lowered ADCP shear and CTD strain profiles / Eric Kunze, Eric Firing, Julia M. Hummon, Teresa K. Chereskin, Andreas M. Thurnherr.

In: Journal of Physical Oceanography. (2006.), Vol. 36(8) (2006)
Abstract: Internal wave-wave interaction theories and observations support parameterization for turbulent dissipation rate ε and eddy diffusivity K that depends on internal wave shear and strain variances. Latest incarnation is applied to 3,500 lowered ADCP/CTD profiles from Indian, Pacific, North Atlantic and Southern Oceans. Inferred diffusivities K are functions of latitude and depth. Turbulence is highly heterogeneous. Though bulk of vertically integrated dissipation is contributed from main pycnocline, hotspots show some correlation with small-scale bottom roughness and near-bottom flow at sites where strong surface tidal dissipation resulting from tide-topography interactions has been implicated. Average vertically integrated dissipation rates are closer to value expected for canonical internal wave spectrum than to value for global-averaged deep-ocean surface tide loss.
