The waters of the Tristan da Cunha archipelago are vast, covering an area about three times the size of the U.K. mainland. They are relatively unspoiled and vitally important for a wide range of fish, birds, whales, and seals. The remote location of this British overseas territory in the South Atlantic Ocean—about 2,400 kilometers east of South Africa—means that a large number of these species are found nowhere else on Earth.
Tristan’s waters are the feeding ground for the Tristan and Atlantic yellow-nosed albatross, as well the critically endangered spectacled petrel. This petrel’s population has dropped to just 10,000 breeding pairs, all living on the archipelago’s aptly named Inaccessible Island. Tristan’s islands are home to 80 percent of the sub-Antarctic fur seal population and important populations of southern elephant seals. Nearly all of the world’s northern rockhopper penguins live here.
Pew continues to explore ways to protect the marine environment of Tristan da Cunha while supporting community needs.
The ocean covers nearly three-fourths of the globe and is home to almost a quarter of the world’s known species—with many more yet to be discovered. It plays an essential role in sustaining life by regulating global chemistry and climate and providing sustenance for billions of people. But human activities are increasingly threatening the ocean’s health. Many experts... Read More
In recent years, the British government has led the world in marine protection.
