The interest on understanding and quantifying topographically induced turbulent mixing in oceans has increased profoundly during the last decade. Basin-scale dynamics of deep waters is known to depend on vertical mixing near the bottom and hence it must be correctly represented in the models of ocean circulation. Rough topography has been pointed out as possible hotspots for deep-ocean mixing. This talk is focused on parameterization of abyssal mixing as well as on boundary mixing in shallow seas and related phenomena - fine structure and internal waves.
