gyre, known as the Socotra Eddy, was centered at approximately 12°N and 57°E 

 with an approximate diameter of 200 nautical miles. The two eddies were 

 separated by a trough of cold water advected from the region of upwelling off 

 the Somali coast between 9°n and llON. Studies of TIROS-N satellite infrared 

 photographs and XBT cross-sections taken from tankers transiting the area 

 during July and early August 1979 indicated the presence of a southern eddy 

 separated from the Great Whirl by a trough of cold, upwelled water between 

 3°N and 5°N. During the early part of the WILKES survey, the southern eddy 

 and the Great Whirl coalesced.
