The Great Bahama Bank is a large shallow water body located between Great Exuma and Andros islands in the Bahama Archipelago.
The sea in this stretch of water has depths of no more than 5 metres. The limited depth of the seabed favours the growth of corals that cover much of the Bank. The marine area also has a considerable ecological value as it supports a complex food chain, as phytoplankton and some valuable species of tuna proliferate in the growing seasons.

In 2016, the Bahamas government started a process to protect at least 20% of its marine environment, including the Great Bahama Bank.
Built essentially as a land monitoring mission, the Copernicus Sentinel-2 satellites are now found to be very useful for a multitude of marine applications such as monitoring coastal waters and coral reefs, bathymetry, detecting marine debris etc.
