Abstract:

Long term goal of our research is to identify and evaluate key processes responsible for the generation, maintenance, and decay of oceanic turbulence. Enhancement of vertical mixing by bottom topography in deep oceans and in coastal regions is a problem of our top priority. The current project is focused on studying the decay of turbulence downstream of seamounts and analyzing the statistics of topography-induced mixing in different oceanic layers. We also plan to quantify the influence of vertical shear on the nature of turbulence on shallow shelves. The impact of background shear on the generation of density fine-structure induced by boundary forcing appears to be an important phenomenon that should be considered in parameterization of ocean mixing processes, and our current work delves into this aspect using numerical modeling.
