Figure 3. Gulf Stream rings. Position of the north wall of the Gulf Stream 

 and five warm core rings in late March 1982 based on satellite imagery. Ring 

 82A lies just to the south of Lydonia Canyon. When these rings are close to 

 the shelf break, the strong clockwise circulation around them causes eastward 

 flow along the outer edge of the shelf. In the absence of rings, currents 

 over the shelf and over the canyon are westward.
