Pedro Bank is a large bank of sand and coral, partially covered with seagrass, about 80 km south and southwest of Jamaica, rising steeply from a seabed of 800 metres depth. It slopes gently from Pedro Cays to the west and north with depths from 13 to 30 metres. The total area of the bank within the 100-metre (328-foot) isobath measures 8,040 square kilometres. The area of a depth to 40 metres is triangular, 70 kilometres long east-west, and 43 kilometres wide. 2,400 square kilometres are less than 20 metres deep. With its islets, cays and rocks, a total land area of 270,000 m2 (2,906,256 sq ft), it is the location of one of the two offshore island groups of Jamaica, the other one being the Morant Cays. The bank is centered at 17°06′N 78°20′W.
