Exuma Sound is a deep oceanic basin located within the Bahamian archipelago, bounded by the Exuma Cays to the west and Eleuthera and Cat Island to the east. In contrast to the surrounding shallow Bahama Banks, the Sound reaches depths of 1,500 to over 2,000 meters, forming a significant indentation in the carbonate platform. This geological feature allows for the upwelling of nutrient-rich deep waters along its margins, supporting exceptional marine biodiversity at the reef edges. The Sound serves as a major migratory corridor for large pelagic species such as marlin, tuna, and various sharks, making it a hub for international sport fishing. The transition from the shallow banks to the precipitous drops of the Sound, frequently referred to as 'The Wall,' is famous among divers for its dramatic coral formations and sightings of large marine life. Oceanographically, the Sound is connected to the Atlantic via several channels, influencing water exchange and thermal regulation in the region. The Cape Eleuthera Institute at the southern end conducts extensive research on deep-sea and pelagic ecology.
