The slope water off the Scotian Shelf forms a well-defined band between the coastal waters and the Gulf Stream. Its boundaries fluctuate widely with no apparent systematics, sometimes transgressing upon the Shelf.A survey in November 1951 indicates the presence of alternate bands of cold and warm water in the slope water and suggests that these are the direct result of instability in the northern edge of the Gulf Stream. Observed velocities support such a hypothesis. Temperature-salinity relationships indicate that the slope water is formed of waters from the surface layers of the Gulf Stream, surface coastal waters, Labrador waters and deep Atlantic waters which have upwelled under the Gulf Stream.

Regional Atmospheric Model

Abstract The mechanisms acting on near-surface winds over the Gulf Stream are diagnosed using 5-yr outputs of a regional atmospheric model. The diagnostics for the surface-layer momentum vector, its curl, and its convergence are developed with a clear separation of pressure adjustment from downward momentum inputs from aloft in the surface-layer system. The results suggest that the downward momentum mixing mechanism plays a dominant role in contributing to the annual-mean climatological momentum curl, whereas the pressure adjustment mechanism plays a minor role. In contrast, the wind convergence is mainly due to the pressure adjustment mechanism. This can be explained by the orientation of background wind to the sea surface temperature front. The diagnostics also explain the relatively strong seasonal variation in surface-layer momentum convergence and the small seasonal variation in curl. Finally, the surface-layer response to other western boundary currents is examined using a reanalysis dataset.
