The Bahama Banks: Little Bahama Bank in the north and Great Bahama Bank in the south. The Cay Sal Bank is also visible.

The Bahama Banks are the submerged

Turks Islands, and wholly submerged Mouchoir Bank. Farther southeast are the equally wholly submerged Silver Bank and Navidad Bank north of the Dominican Republic
.

Geologic history and structure

The limestone that comprises the Banks has been accumulating since at least the Cretaceous period, and perhaps as early as the Jurassic; today the total thickness under the Great Bahama Bank is over 4.5 kilometres (2.8 miles).[1] As the limestone was deposited in shallow water, the only way to explain this massive column is to estimate that the entire platform has subsided under its own weight at a rate of roughly 3.6 centimetres (2 inches) per 1,000 years.[1]

The waters of the Bahama Banks are very shallow; on the Great Bahama Bank they are generally no deeper than 25 meters (80 feet).[2] The slopes around them however, such as the border of the

sinkholes common to karst terrain, resulting in structures like blue holes.[1]
