The Coastal Gulf of Alaska Circulation Model (3-km grid)

The SALMON Project is currently utilizing the Arctic Region
Supercomputing Center (ARSC) to run numerical simulations of the
circulation of the coastal Gulf of Alaska. The model in use is called
the Regional Ocean Modeling System (ROMS), developed jointly by
researchers at the University of California at Los Angeles and Rutgers
University. It is run at a resolution of three kilometers and aligned
in a nested grid configuration with Al Hermann's North East Pacific
(NEP) domain. Open boundary conditions are provided by the NEP model
and COADS monthly mean wind fields are used for the surface
forcing. Tidal forcings are computed from Mike Foreman's northeast
Pacific Ocean high-resolution assimilating tide model (Foreman et al.,
2000) and are applied along the open boundaries of the model
domain. Fresh water inputs consist of a continous line source of
monthly mean values computed by Tom Royer's hydrologic model (Royer et
al., 2001). The latest ROMS model run simulated three idealized years
of circulation in the northern Gulf of Alaska.
