At Cape Hatteras the Gulf Stream leaves the Continental Slope, so that as far as the deep current is concerned its course is no longer confined. The current again approaches the Continental Shelf off Georges Bank and off the Grand Banks, hut in neither area does it flow normally along the Continental Slope as a river pressing against its bank. The band of water which separates the Gulf Stream from the Continental Shelf in the sector between Cape Hatteras and the Grand Banks is usually called "slope water." The great body of water to the south and east of the Stream is known as the Sargasso Sea or Central Atlantic water.
