Generalized Sponge regions for relaxing back to (T,S) at all depths and, optionally, to a barotropic stream function obtained from a larger domain run. The utility, mask2full, in the NEW directory can be used for easily adding sponges to your model geometry by expanding your Grid_mask specification into an easy-to-edit file.
Generalized Relax regions for relaxing back to surface data instead of
using AML. See comments about
