The Archipelago of São Pedro and São Paulo (ASPSP) is a group of rocky islands located about 1,000 km off the coast of Rio Grande do Norte, with a total emerged area of is approximately 17,000 m2 . The low altitude and small size made the location a critical point for navigation, because the islands are difficult to detect with the naked eye, especially under adverse light and weather conditions - which have led to shipwrecks in the past.

The first and most famous of them was the one that led to the discovery of the archipelago. It involved the Portuguese ship São Pedro, under the command of Captain Manuel de Castro Alcoforado, which, in 1511, crashed against rocks when she strayed from the rest of the fleet, which had set sail from Portugal - on 20 April 1511 - towards India . The rescue ship that rescued São Pedro was from the same fleet, and she was called "São Paulo". Hence the name "São Pedro and São Paulo". The first map record of that remote region dates back to 1529, and Brazil's ownership of it has never been challenged.

The first Scientific Station built on the ASPSP was inaugurated on June 25, 1998; since then, the site has remained permanently inhabited.

The Archipelago of São Pedro and São Paulo (ASPSP) consists of a set of rocky islands, located in the northern hemisphere, on the Mid Atlantic Ridge (00° 55.01' N and 029° 20.76' W, about 1,100 km from Natal - RN, and 520 km from Archipelago of Fernando de Noronha - PE). It is Brazil's closest point to Africa, about 1,820 Km from Guinea Bissau. It is a remote group of islands near the equator, occupying and emerged area of about 17,000 m2, with a maximum elevation of 18 m above sea level.

The following features are observed on-site:

- Hot and humid climate;

- Rocky soil (dark, jagged rocks);

- Lack of beaches;

- Lack of medium / large-sized vegetation;

- The surrounding sea is relatively violent;

- High possibility of earthquakes; and

- Rich biodiversity.

Located about 1100 km from the coast of Rio Grande do Norte, the Archipelago of São Pedro and São Paulo (ASPSP) is the only set of Brazilian oceanic islands above the equator. It is composed of small, rocky islands created due to the geological evolution associated to the Sao Paulo tectonic fault. It is an upwelling ocean mantle, which rises from abyssal depths of around 4000 meters , with a total emerged area of 17,000 square meters.

Despite its extremely inhospitable nature, the ASPSP has unique characteristics that provide unique economic, scientific and strategic opportunities to the country.

- Economic interest - the ASPSP is located on the migratory route of high-value fish; it is a very promising area for the domestic fishing sector.

- Scientific Interest - the ASPSP has always attracted large scientific interest. It is a rare case of island formation - the archipelago is surrounded by rich biodiversity, which provides unique conditions for conducting research in various branches of science.

- Strategic Interest - The United Nations Convention on the Law of the Sea (UNCLOS), signed by Brazil in 1982 - and subsequently ratified in December, 1988 - changed the legal framework pertaining to international maritime spaces, establishing the right of coastal States to explore and use the natural resources of the water column, of ocean soil and subsoil, across the Exclusive Economic Zone. However, in relation to the "Regime of Islands", Article 121 of the Convention, paragraph 3, states that: "Rocks which cannot sustain human habitation or economic life of their own shall have no Exclusive Economic Zone (EEZ) or Continental Shelf". Therefore, if guarantees the continuous habitability of that remote region, allowing the country to add a stunning ​450,000 km2 to its original EEZ , which accounts for approximately 13% of the entire EEZ, or 6% of Brazilian territory.

In 2004, the Navy, through Official Letter No. 902/2004/Com3ºDN, requested that the Regional Manager of Federal Heritage in Rio Grande do Norte (GRPU/RN) take the appropriate clearance at the Federal Heritage Secretariat (SPU), to transfer jurisdiction over the ASPSP to the Navy of Brazil, through the appropriate Term of Delivery. This term came into effect when it was signed, in 2006, by Fleet Admiral Roberto de Guimarães Carvalho, then Commander of the Navy, and Mrs. Yêda Cunha de Medeiros Pereira, then Regional Manager of the Federal Heritage in Rio Grande do Norte.

estação científica do Arquipélago

The Scientific Station of the Archipelago of São Pedro and São Paulo was inaugurated on June 25, 1998. Although it proved adequate to the weather in the region, over the years, the site proved vulnerable to the frequent impacts of strong waves. This led to the construction of a new station, to ensure the continuity of researchers in the area, even more safely and comfortably.

In this sense, the National Council of Scientific and Technological Development (CNPq) approved funding for the construction of a new Scientific Station. Given the project needs, and in order to abide by logistical and financial constraints, the installation of the new station took place in three distinct stages:

- Construction of concrete foundations: from 24 to 27 of July, 2007;

- Assembly of the house, from October 26 to November 5, 2007; and

- Instalação dos equipamentos elétricos e hidráulicos: 14 a 25 de junho de 2008.

The construction project was coordinated by SECIRM and took about two years to implement effectively. The consecutive evaluations of the first station allowed for the design of guidelines that guided the work, so that the solutions adopted successfully in the initial design were repeated, while those that did not have the expected outcomes, or were subjected to unforeseen situations, were replaced or improved. The various construction steps involved many Navy Military Organizations and research institutions:

navio que apoia as pesquisas no arquipélago

- Command of the 3rd Naval District;

- Natal Naval Base;

- Alte Deep Sea Tug. Guilhem;

- Grajaú Patrol Boat;

- Guaíba Patrol Boat;

- UFES Laboratory for Project Planning;

- IBAMA Laboratory of Forest Products;

- ELETROBRAS Center for Electric Power Projects; and


The new Scientific Station has: accommodations for 4 people, living room; laboratory, kitchen, bathroom, balcony, storage area for drinking water and a support building for the emergency power generator and batteries for the photovoltaic system. The site also has a fuel depot, a pier for small vessels, and a walkway, connecting the pier to the main building.

The Scientific Station is occupied by four civilian researchers, rotated every 15 days. Vessels chartered by SECIRM provide transport for these researchers and, for their safety, remain in the vicinity of the archipelago at all times. The station has satellite communications equipment (Iridium), radio (VHF and HF), Internet and a payphone. Archipelago expeditions are conducted quarterly, with the support of ships commanded by the 3rd Naval District, to carry out the preventive and corrective maintenance on buildings and electrical and electronic equipment.
