TheTongue of the Ocean(TOTO) is the name of a region of much deeper water in theBahamasseparating the islands ofAndrosandNew Providence.
Features
editThe TOTO is a U-shaped, relatively flat-bottomed depression measuring approximately 30 by 240 kilometres (20 by 150 mi). Its depth varies gradually from 1,100 m (3,600 ft) in the south to 2,000 m (6,600 ft) in the north.[1]
Its only exposure to the open ocean is at the northern end. Except for the northern ocean opening, the TOTO is surrounded by numerous islands, reefs, and shoals which make a peripheral shelter isolating it from ocean disturbances, particularly high ambient noise.[1]
This channel and theProvidence Channelsare the two main branches of theGreat Bahama Canyon,a submerged geological feature formed by erosion during periods of lower sea level. During their early history the Tongue of the Ocean and the Providence Channel were broad, relatively shallow basins flanked by growingcarbonate banks.As the Blake-Bahama platform subsided, sedimentation kept pace with subsidence on the banks, but not in the basins.[2]
