oceanic water outside the edge of the continent to the south, illustrated more graph- 

 ically in profile (fig. 58) than in horizontal projection. To find water on the conti- 

 nental slope along this profile as cold as the 100-meter reading in the gulf it is 

 necessary to descend below 500 meters, while 10° water was within 40 meters' depth 

 of the surface in the gulf but deeper than 180 meters on the slope. Farther east, where

the basin to the north of the banks is warmer and where a cool wedge intervenes 

 between ocean water and continental edge, a July profile (fig. 59) shows a contrast 

 of only about 1° between the gidf, on the one hand, and the continental slope, on 

 the other, at depths greater than 120 meters. 



These two profiles of Georges Bank are further interesting for outlining the band 

 of cool water that then extended along the bank from northeast to southwest, as just
