Speeds over 2.0 knots may occur between Miami and Cat Cay at a 
depth of 300 meters (984 feet). Speeds over 1.0 knot have been 
observed at 200 meters (656 feet) between Key West and Havana. 
Photographs of current ripple marks on the floor of the northern 
part of the strait in depths over 800 meters (2,625 feet) indicate a 
current generally flowing northward at about O.5 knot, with some 
southward flow also possible but not verified.
