IMPORTANT: Updated ROMS Native Ice Model and added a Test Case

[arango]

The ROMS Native Sea Model was updated and tested with the LAKE_ICE test case. It is an idealized application 200x100x30 at 1km resolution:

The location of the output stations is denoted as S1, S2, S3, S4, S5, S6, S7, and S8 and used to store the time series of the solution at hourly intervals. The vertical grid is well resolved in the upper 20m with a bathymetry range between 20-200m.

ROMS is initialized on Jan-1-2010 and runs for 800 days until Apr-13-2012. Please check the following link for more information, instructions, and solution plots:

• Many thanks to Scott Durski for updating and improving the existing sea ice model, which was initially written by Paul Budgell and maintained and documented by Kate Hedstrom.

• Many thanks to Mike Dinniman for his help in debugging and testing this new version of the sea ice model.
