A region where predictive capability is sought for tactical concerns is the flow field in the vicinity of the continental shelfbreak. Sound propagation from the continental slope to the continental shelf is a complex process that is highly dependent upon the oceanographic environment. A strong thermal shelfbreak front, and its associated current, are the key features that influence acoustic propagation in many shelf regions. Theory and field data suggest that acoustic propagation is strongly affected by frontal features that can evolve on rapid temporal scales 1-2 days and small spatial scales 10-20 km. The overall aim of this proposed work is to improve our ability to realistically model and predict the evolution of the shelfbreak front so as to advance the predictive capability of this region.
