FVCOM Applications Accomplished by the
UMASSD-WHOI Joint Team

• US Coast
• Gulf of Maine/Georges Bank/New England Shelf
• Mount Hope Bay/Narragansett Bay
• South Atlantic Bight
• Georgia and South Carolina estuaries
• Lake Superior
• Cook Inlet/Alaska

• China Coast
• East China Sea/Japan Sea (Spherical Coordinate)
• South China Sea (Spherical coordinate)
• Changjiang River
• Deep Bay/Hong Kong

• New application
• The Arctic Ocean
• Atlantic Ocean

The Integrated FVCOM Model System

The horizontal resolution (measured by the side
length of the triangle) 1-3 km near the coast
and in the Canadian Archipelago, inlets, and
narrow straits 10-15 km in the basin interior.
41 non-uniform ? levels are specified in the
vertical, which corresponds to a vertical
resolution of 10 m near the surface and bottom
and in the main thermoclines in the interior
region where the water is deeper than 4000 m.
Bathymetry data DBDDV (NRL) and IBCAO (NOAA)
The model is driven by the oscillating tidal
elevation at the open boundaries. Four major
tidal constituents (M2, S2, K1, and O1) are
considered here. The amplitudes and phases of
these four tidal constituents at open boundaries
are specified using inversed global tidal model
outputs (TPXO6.2).

Summary

• The finite-volume coastal ocean model (FVCOM) is
  a good choice for regional, coastal and estuarine
  studies
• This model is a potential candidate to bridge the
  global model with the coastal ocean, and the
  continental shelf and estuaries.
