\noindent This research was partially funded by ARPA under ONR contract
N00014-92-J-1310, and grew from a joint effort with John Marshall and Chris
Hill in developing a large ocean circulation model with the MIT Center for
Meteorology and Physical Oceanography.  Kyoo-Chan Cho performed the
original port of the ocean model to Id.
