Abstract:

A key question one must answer before doing an inverse procedure is: ``How deterministic versus stochastic are the fields that are wished to be inverted?'' In this talk, this question is addressed for the coastal processes of solibores, fronts, and coastal eddies, using data from both the SWARM and the shelfbreak front PRIMER experiments, as well as computer models of the processes and acoustic propagation through them. Acoustic propagation over 50-km ranges and frequencies of 50--500 Hz will be considered. Issues concerning the eventual inversion of such data will be discussed in detail.
