Tongue of the Ocean

The TOTO is a U-shaped, relatively flat-bottomed depression measuring approximately {{convert|30|by|240|km|mi|round=10}}. Its depth varies gradually from {{convert|1100|m|ft|abbr=on}} in the south to {{convert|2000|m|ft|abbr=on}} in the north.

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.US Navy AUTEC Soundings, August 1969.

This channel and the Providence Channels are the two main branches of the Great 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 growing carbonate banks. As the Blake-Bahama platform subsided, sedimentation kept pace with subsidence on the banks, but not in the basins.{{cite journal |doi=10.1016/0025-3227(80)90125-5 |title=Geomorphic evolution of the Tongue of the Ocean and the Providence Channels, Bahamas |journal=Marine Geology |volume=35 |issue=4 |pages=343–366 |year=1980 |last1=Hooke |first1=Roger LeB |last2=Schlager |first2=Wolfgang |bibcode=1980MGeol..35..343H }}
