A remote mountain range serves as a nursery for the Antarctic

In short: In the middle of the Antarctic Ocean, a rugged mountain range rises from the water to create a sanctuary for marine life. This island is so densely packed with wildlife that penguins significantly outnumber the few humans who call it home.

Situated roughly 800 miles (1,300 km) east-southeast from the Falkland Islands, South Georgia is a desolate, hilly landmass within the South Atlantic Ocean. It is a British overseas territory, though Argentina also maintains a territorial claim. The island's geography is defined by the Allardyce Range, with Mount Paget reaching a height of 9,625 feet (2,934 metres). Its harsh Antarctic climate features perpetual snow covering three-fourths of the land, supporting only hardy tundra plants and grasses.

The island is famous for its massive colonies of King Penguins, elephant seals, and fur seals. Because of the extreme weather and difficult access, documenting the lives of these animals requires years of patience and high-end filmmaking equipment. For example, a recent five-year study by filmmakers Roland Gockel and Rosie Koch provided rare, poignant insights into the life of King Penguins on the island.

The history of South Georgia is marked by both human exploration and environmental challenges. It served as a whaling base in the 19th century, with the Norwegian settlement of Grytviken founded in 1904. While whaling ceased in 1965, the island remains a site for scientific research and commercial fishing of species like Patagonian toothfish. The island also faced a severe ecological crisis when brown rats, introduced in the 1800s, nearly wiped out endemic bird species like the South Georgia pipit. Fortunately, the rats were eliminated by 2015, allowing for a significant environmental recovery.

Today, the island's only permanent inhabitants are a small number of scientists and support personnel from the British Antarctic Survey. Their numbers fluctuate between 12 and 44 depending on the season. While the town of Grytviken is no longer permanently inhabited, it remains a significant historical site where the explorer Sir Ernest Shackleton is buried.
