Double diffusive convection is possible where large vertical gradients in temperature and salinity tend
to compensate in density. Frontal intrusions have these large gradients and can provide the possibility for
a salt finger interface at one boundary and a diffusive interface at the other. But large vertical gradients
of velocity are present at the boundaries of intrusions, which cause mechanical stirring and turbulent
mixing as well. In the exceptionally active intrusions at the Gulf Stream Front near 38°N 69°W, a convective
process resulting from incomplete mechanical mixing was observed photographically on both intrusive
boundaries.

Eddy diffusivity from Argo temperature and salinity profiles
Cole, Sylvia T.; Wortham, Cimarron J. L.; Kunze, Eric; Owens, W. Brechner (2018-04-10)Argo temperature and salinity profiles are combined with ECCO-2 velocity profiles to estimate eddy diffusivity in the upper 2000 m of the global ocean. The dataset includes relevant intermediate parameters (mixing length, ... -
