The Puerto Rico Bank (PRB) (Spanish: Banco de Puerto Rico), also known as the Greater Puerto Rico Bank (PRB), is a submerged carbonate platform comprising the archipelagos of Puerto Rico[a] and the Virgin Islands.[b] Measuring 350 km (218 mi) in length, 40 to 80 km (25 to 50 mi) in width, and up to 79 m (260 ft) in depth, the bank is separated from the Greater Antilles by the Mona Passage, and from the Lesser Antilles by the Anegada passage. With an area of 21,000 sq km (8,108 sq mi), it was last fully exposed during the Last Glacial Maximum when the sea level was 120 m (400 ft) lower than the present-day. The bank was inundated by sea level rise during the Late Pleistocene and Early Holocene, losing subaerial connection the Virgin Islands with each other and with Puerto Rico 10,000 to 8,000 years ago, and the main island of Puerto Rico with the islands of Vieques, Caja de Muertos, and other cays and islets 6,000 years ago.
