Variability in the Slope Water and its relation to the Gulf Stream path
MetadataShow full item record
Sea Surface Temperature (SST) and Sea Surface Height (SSH) data for 1993–2007 for the North Atlantic are combined with hydrographic data at 69W to investigate the relation between the Gulf Stream (GS) position and the Slope Water properties. SST anomalies north of the GS are correlated with changes in its path. The lag of this correlation is such that positive temperature anomalies precede northward shifts of the GS, and suggests that SST anomalies move westward with speeds of several cm/s. EOF analysis of the SST and SSH fields shows that cooling and strengthening of the SW flow are in phase over the Slope Water, which is mirrored in the vertical structure of these fields at 69W, indicating larger transports in the Deep Western Boundary Current lead to southward shifts of the mean GS path. This relation between the Slope Water and the GS path provides some predictability for the latter.

Oceanographic study of warm core Gulf Stream rings and the Northwest Atlantic Slope Water region : a prospectus for multidisciplinary research, report and proceedings / Interdisciplinary Workshop on Gulf Stream Anticyclonic Eddies (Warm Core Rings) held at the Woods Hole Oceanographic Institution, May 16-20, 1977 Unknown author (Woods Hole Oceanographic Institution, 1977-05)It is well recognized in the oceanography of the Western North Atlantic that a distinct hydrographic regime exists between the continental shelf and the Gulf Stream, once the latter has effectively separated from the ...
Slope water, Gulf Stream, and seasonal influences on southern Mid-Atlantic Bight circulation during the fall-winter transition Rasmussen, Linda L.; Gawarkiewicz, Glen G.; Owens, W. Brechner; Lozier, M. Susan (American Geophysical Union, 2005-02-16)Observations from autumn, 2000, near the shelfbreak front in the Middle Atlantic Bight are used to describe the transition from stratified summer conditions to well-mixed winter conditions over the shelf.

On the midwater fish faunas of Gulf Stream rings with respect to habitat differences between slope water and northern Sargasso Sea Jahn, Andrew E. (Woods Hole Oceanographic Institution, 1976-04)Forty-three 1000-in oblique Isaacs-Kidd midwater trawl collections were made on six cruises. In most cases, these were accompanied by 1500-m hydrocasts and plankton tows to 800 m. The fish collections comprise 19,400 ...
