The Bahama Islands are characterized by the presence of thousands of square miles of shallow sea (<5 fathoms) lying between the various islands. The most extensive of these are the Great Bahama, Little Bahama and Exuma Banks (cf. Fig. 44). A certain amount of discussion has arisen concerning these areas, both in relation to their geological formation and to chemical changes taking place in the water.
