Mean Eulerian subsurface currents measured in the Gulf of Maine and adjacent Scotian and New England shelf and slope regions, 1974-1980

Abstract

The Bedford Institute of Oceanography, E.G.&G., National Marine Fisheries Service, U.S. Geological Survey, and Woods Hole Oceanographic Institution have conducted separate moored array experiments during 1974- 1980 to study various aspects of the regional circulation in the Gulf of Maine and adjacent Scotian and New England shelf and slope regions. The mean currents and current variances measured in these experiments are summarized here in tabular and graphical form, together with other information about each experiment. While there have been few measurements made in the interior of the Gulf of Maine, the map of mean subsurface currents demonstrate (a) a net inflow of Scotian shelf water past Cape Sable into the Gulf, (b) a net inflow of slope water through the Northeast Channel into the Gulf, (c) a partially closed anticyclonic circulation around Georges Bank, and (d) a net outflow of shelf water south of Nantucket from the Gulf of Maine into the New England shelf.
