Uncharted island will soon appear on nautical charts

A 93-strong international expedition team has been exploring the northwestern Weddell Sea in the Antarctic on board the Alfred Wegener Institute's icebreaker Polarstern since February 8, 2026. In this key region for global ocean currents, the focus has been on the outflow of ice and water from the Larsen Ice Shelf and the astonishing sea ice retreat of recent years. When the research work had to be interrupted due to rough weather conditions in order to seek shelter in the lee of Joinville Island, the scientists and ship's crew were surprised by the sudden appearance of an island that had previously only been marked as a danger zone on the available nautical charts.
