| Description | : | The Gulf of Maine (GoM) is known for its high biological productivity, active commercial fishery, and attractive beaches. It communicates with the surrounding ocean via inflows of fresh/cold water from the upstream Scotian shelf and warmer/saltier slope water from the surrounding shelf via the Northeast Channel. Most Scotian shelf inflow circulates around southwestern Nova Scotia. This allows the selection of a regional gauge area for its monitoring. This study defines and explores the utility of a new Gulf-specific water mass exchange predictor based on satellite sea surface salinity in the eastern GoM (eGoM) designed to capture changes in winter inflow from the Scotian Shelf. A data assimilative ocean model is used to characterize and assess results. The eGoM salinity index helps explain the interannual variability of inner GoM near-surface salinity during the following spring and summer, which is influenced by westward transport along a newly suggested central Gulf pathway. |
