South Great Bahama Bank

The Great Bahama Bank is a vast shallow carbonate platform supporting the Exuma Cays and other low islands. To the east of the Exumas the seabed falls into the deep Exuma Sound, while the Tongue of the Ocean separates the cays and New Providence from Andros. Tides sweep across the platform's margins, building banks of rounded carbonate grains. The pale sands and shoals stand in sharp contrast to the deep channels beside them.
