Barbados is a continental island in the North Atlantic Ocean and is located at 13°10' north of the equator, and 59°32' west of the Prime Meridian. As the easternmost isle of the Lesser Antilles in the West Indies, Barbados lies 100 kilometres (62 mi) east of the Windward Islands and Caribbean Sea. The maritime claim for Barbados is a territorial sea of 12 nmi (22.2 km; 13.8 mi), with an exclusive economic zone of 200 nmi (370.4 km; 230.2 mi), this gives Barbados a total maritime area of 183,436 km². Of the total EEZ area 70,000 km², is already set aside for offshore oil exploration. A pending application to UNCLOS has placed for consideration a continental shelf 200 nmi (370.4 km; 230.2 mi) to the east and south (or to the edge of the continental margin). To the west, however, most of Barbados' maritime consist of a median lines with neighbours.
