Salinity Forecast Guidance
This near surface water salinity animation was created from the latest GOMOFS forecast guidance in the Gulf of Maine. The forecast is for the next 48 hours of surface water salinity as simulated by GOMOFS when it is forced by forecast products from the National Weather Service's North American Model (NAM) and Global operational Real-Time Ocean Forecast System (RTOFS).
