Revised DART-05 modeling domains

(Click on image for full resolution figure)

To the right are the proposed Harvard modeling domains for DART-05, overlying a 1 minute topography from Paolo Oddo and the GSHHS coastlines. Included on the figure are the isobaths delimiting the operational limits of the SEPTR buoy (100m) and the Barny ADCP (300m).

The Harvard domains (outlined in white) are a set of telescoping 2-way nestable grids. The basic rational for these domain are:

Adriatic (Largest): A domain spanning the full Adriatic Sea, aligned with the major axis of the sea (positive "X" points out the mouth of the Adriatic and positive "Y" points towards the Balkan Peninsula).
Mid-Adriatic (Middle): A domain spanning the initial sampling region of the experiment. The domain spans the full width of the Adriatic.
Gargano/Gulf of Manfredonia (Smallest): A sample domain to resolve eddies shed off the Gargano Peninsula.

This set of domains was derived based on the resolution of an Adriatic domain Paolo Oddo was using, slightly modified to provide an integral set of potential nests {4050m, 1350m, 450m, 150m, 50m}. The speed estimates are made by comparing the grid sizes against 2 different experiments that were run with the given time steps.
