These are the Yucatán, Cayman, Colombian, Venezuelan, and Grenada basins. The northernmost of these, Yucatán Peninsula and has a sill depth (i.e., the depth of the submarine ridge between basins) of about 5,250 feet (1,600 metres). Bottom temperature of the Caribbean Sea is close to 39 °F (4 °C), as compared with the Atlantic bottom temperature of less than 36 °F (2 °C) which make is the perfect deep diving destinaton.
