To commemorate the extraordinary moment the ozone hole was discovered in Antarctica 40 years ago, British Antarctic Survey (BAS) has teamed up with the Royal Geographical Society (RGS) in London to host a special series of talks on Tuesday, 6 May 2025.
Add your comment!For the first time, scientists have collected measurements close to a giant iceberg, giving an unprecedented window into the impact of meltwater on the surrounding Southern Ocean and ecosystem. The paper is published in the journal Nature Geoscience.
The waters surrounding South Georgia, nestled beneath glaciated mountains, are among the most biologically rich in the Southern Ocean. In February, a team of scientists from the British Antarctic Survey (BAS) and international institutions embarked on an important research expedition to explore the diverse marine life – including ground-fish – thriving 300 meters below the surface.

A new map of the South Orkney Islands has been released by British Antarctic Survey (BAS) – the first UK published, topographic map of the region in almost 40 years. Created by the Mapping and Geographic Information Centre at BAS, the map offers a detailed topographic view of the entire South Orkney archipelago on one side, with a focused, high-resolution map of Signy Island on the reverse.
Scientists have discovered microplastics in the snow near some of Antarctica’s deep field camps, revealing how far-reaching plastic pollution has become. While not new, it’s the first time these tiny pieces of plastic have been found in remote locations.
British Antarctic Survey scientists on the sub-Antarctic island of South Georgia are working to better understand the rich marine life that inhabits the region. This month teams are focusing on two major projects: one on whales and their consumption of krill (a shrimp-like creature that’s abundant in the Southern Ocean), and another on populations of bottom-dwelling fish. Their findings will help ensure the long-term health of the region’s ocean ecosystem and support sustainable fisheries.
Congratulations to British Antarctic Survey (BAS) staff who have been awarded a Polar Medal in the 2025 New Year’s Honours List for their contributions to improving our understanding of Antarctica, through scientific or technical work in or about the Polar Regions.
A23a, arguably the world’s largest and oldest iceberg which has been wandering through the South Atlantic and headed for the British Overseas Territory of the South Georgia Islands since last month, has been reported not to have changed course this week nor upped nor melted, thus posing a serious threat to the local fauna. Earlier this week, it was spotted 173 miles (280km) away.
According to the British Antarctic Survey (BAS), the 3,600 square kilometer iceberg known as A23a broke off from Antarctica and was reportedly going adrift in the South Atlantic, probably towards South Georgia Island. It is arguably the world's largest and oldest iceberg, with ice sheets 400 meters thick, and weighing almost one billion tons.
