Trindade and Martim Vaz, Remote volcanic archipelago in South Atlantic Ocean, Brazil
Trindade and Martim Vaz form a scattered cluster of volcanic landforms in the South Atlantic, lying more than a thousand kilometers off the Brazilian coast. The larger formation rises steeply from the sea to around six hundred meters, while the smaller rocky outcrops barely break the surface.
A Portuguese navigator sighted the group in the early sixteenth century during a return voyage from India. The naval station was established in the mid-twentieth century after earlier attempts at permanent settlement had failed.
The Brazilian Navy maintains a scientific station on Trindade Island since 1957, conducting meteorological observations and environmental research programs.
The area is under military administration and access is tightly restricted. Visitors should expect warm weather and brief bursts of rain throughout the day.
Great frigatebirds arrive here to nest, and nowhere else in the Atlantic does this species find suitable conditions. Sea turtles lay thousands of eggs along the coasts, as the remote location sharply reduces disturbance.
