Tongue of the Ocean (Paperback)

High Quality Content by WIKIPEDIA articles! The Tongue of the Ocean is the name of a deep oceanic trench in the Bahamas separating the islands of Andros and New Providence. The depth of the water drops from roughly 115 feet (35 m) along Andros' east offshore barrier reef to over 6,000 feet (1.8 km), and the drop is roughly 100 miles (160 km) long.This channel and the Providence Channel 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 Channels 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.
