Topographic Influences on Shelf Circulation

Abstract

The overall goal of this effort was to use a hierarchy of process oriented numerical modeling studies to study the role played by a continuum of bottom bumps on flow over the continental shelf. Observed cross shelf currents over the shelf tend to have higher amplitudes and shorter length scales than can be accounted for by existing models. The approach here was to ask whether model experiments could produce realistic (in terms of amplitude and statistical quantities such as length scales) cross shelf currents under reasonable conditions. The primary results obtained from the study were obtained from a barotropic, nonlinear model, and the results are encouraging but incomplete in that density stratification was not included.
