Straits of Florida Straits of Florida The Straits of Florida, Florida Straits, or Florida Strait () is a strait located south-southeast of the North American mainland, generally accepted to be between the Gulf of Mexico and the Atlantic Ocean, and between the Florida Keys (U.S.) and Cuba. It is 150 km (93 mi) wide at the narrowest point between Key West and the Cuban shore, and has been sounded to a depth of 6,000 feet (1,800 m). The strait carries the Florida Current, the beginning of the Gulf Stream, from the Gulf of Mexico. Five wells were drilled in state waters south of
Fram Strait called the Atlantic water. The sub-surface flow has a strong seasonality with a minimal volume transport in winter. This current transports internal energy into the Arctic Ocean . The northward velocity is maximum in winter, so the "heat transport" is highest in winter. On the west side of the strait, the East Greenland Current flows southward on the Greenland Shelf. The current carries is relatively cold and fresh water out of the Arctic that corresponds to a water mass called Polar water. The Fram Strait area is located downwind of the Transpolar Drift and therefore covered by multi-year ice in
