Guinea, Gulf of

Part of the Atlantic Ocean off the coast of western Africa between Cape Palmas, Liberia, and Cap Lopez, Gabon. It includes the coastal features of the Bight of Benin and the Bight of Bonny (Bight of Biafra), separated by the delta of the River Niger. The rivers Volta, Niger, and Ogooué flow into it.

The gulf contains the islands of Bioko, (formerly known as Fernando Poo and Macías Nguema Bijogo (1973–79)), Príncipe, São Tomé, and Annobón (Pagalu). It receives currents crossing the Atlantic near the Equator, and sends out the equatorial current which flows in the opposite direction, finally giving rise to the Gulf Stream.
