A High‐Resolution 3‐D Circulation Model in a Complex Archipelago on the Coastal Scotian Shelf

چکیده

A high-resolution coastal Finite-Volume Community Ocean Model (FVCOM) has been configured to simulate the water circulation in Eastern Shore Islands (ESI) archipelago on Scotian Shelf. Circulation this area is characterized by complex interactions between irregular coastline, a dense archipelago, tides, wind, and subtidal currents. outputs show close agreement with current, hydrographic observations. Two regimes within study were identified “inshore” “offshore” of 60-m isobath. The balance pressure gradient Coriolis effect controls dominant southwestward current (Nova Scotia Current) offshore. Rotary spectra numerical experiments showed that tidal was an important component inshore. Within there are several clockwise counter-clockwise gyres related effect, surface wind stress, gradient, interaction topography current. combined effects topography, tide, Nova Current regulate inshore circulation. topographic features cross-shore transport. increased bathymetric slope strengthened relative vorticity contribute Here, we found joint baroclinicity bottom relief drives cross-isobath ability our model resolve patterns provides basis which better understand how physical oceanography influences unique ecological processes ultimately will help evaluate dispersal connectivity species area.

The onset and evolution of a spring bloom on the Scotian Shelf

The spring bloom on the Scotian Shelf is examined using a mooring array deployed from 18 March 2002 to 18 April 2002 to provide physical, chemical, and biological measurements with high temporal and vertical resolution. These measurements are complemented by the Atlantic Zone Monitoring Program (AZMP) biweekly occupations of a station near the mooring site (HL2). Results from AZMP sampling and ...
