For decades, mariners in the United States have depended on NOAA's Tide Tables for the best estimate of expected water levels. These tables provide accurate predictions of the astronomical tide (i.e., the change in water level due to the gravitational effects of the moon and sun and the rotation of the Earth); however, they cannot predict water-level changes due to wind, atmospheric pressure, and river flow, which are often significant.
To better serve maritime user community, a new three-dimensional Gulf of Maine Operational Forecast System (GoMOFS) was developed by the NOAA/National Ocean Service/Office of Coast Survey in a joint project with the NOAA/NOS/Center for operational Oceanographic Products and Services (CO-OPS) and the NOAA/National Weather Service/National Centers for Environmental Prediction (NCEP) Central Operations (NCO) using Rutgers University's Regional Ocean Modeling System (ROMS). GoMOFS generates nowcasts (analyses of near present) and forecast guidance of water level, current, temperature and salinity out to 72 hours, four times per day. Aerial animations of the whole Gulf of Maine as well as time series at particular stations or points of interest are available for over 20 locations for the five parameters (water level, currents, temperature, and/or salinity). GoMOFS will assist U.S. port authorities and mariners in efficiently navigating the Gulf of Maine without compromising safety.
GoMOFS runs on NOAA's High Performance Computers (HPC) in a new Coastal Ocean Modeling Framework (COMF) developed by CO-OPS. As a result, GoMOFS has direct access to National Weather Service operational meteorological products that it needs to run reliably.

Disclaimer: The Gulf of Maine Operational Forecast System (GoMOFS) has been implemented by NOAA's National Ocean Service (NOS) to provide the maritime user community with short-term predictions of water levels, water currents, water temperatures and salinity of the Gulf of Maine. GoMOFS uses a numerical hydrodynamic model to generate the nowcast and forecast information; therefore, they should be considered as model-generated nowcast and forecast guidance.
