Saint Peter and Saint Paul Archipelago

Travel Guide South America Brazil Pernambuco Saint Peter and Saint Paul Archipelago



The Saint Peter and Saint Paul Archipelago is a group of 15 small islets and rocks in the central equatorial Atlantic Ocean. It lies in the Intertropical Convergence Zone, a region of the Atlantic characterized by low average winds punctuated with local thunderstorms. It is a special municipality of the Brazilian state of Pernambuco and lies approximately 510 nmi (940 kilometres) from the Brazilian northeastern coastal town of Touros, 625 kilometres northeast of the archipelago of Fernando de Noronha, 990 kilometres from the city of Natal, and 1,824 kilometres from the west coast of Africa.

The islets expose serpentinized abyssal mantle peridotite and kaersutite-bearing ultramafic mylonite atop the world's highest and yet only second largest megamullion (after the Parece Vela megamullion under Okinotorishima in the Pacific Ocean). This grouping is the sole location in the Atlantic Ocean where the abyssal mantle is exposed above sea level.

In 1986, the archipelago was designated an environmentally protected area. This is now part of the Fernando de Noronha Environmental Protection Area. Since 1998, the Brazilian Navy has maintained a permanently manned research facility on the islands. The main economic activity around the islets is tuna fishing.
