  1. Under Development • 2-way coupling between ocean and atmosphere circulation models – put the O in COAMPS • Couple wave models with ocean and atmospheric circulation models • Automate flow of data and model results from one model to another – DIOPS for waves • Integrate sediment transport models with coastal circulation models • And I haven’t even talked about ice modeling!
