Caught in a storm in Antarctica, German scientists made an unexpected discovery. While seeking shelter, they stumbled upon an island that had never appeared on any map.
What was meant to be a strictly planned expedition took an unforeseen turn… Last February, a team aboard the icebreaker Polarstern made an unplanned discovery in the Weddell Sea, Antarctica. As they sought refuge from a violent storm, the scientists spotted a landmass absent from existing charts.
A discovery born from the unexpected in Antarctica
For this mission, the Alfred Wegener Institute’s vessel was carrying no fewer than 93 researchers, tasked with studying the glaciers of the Larsen Ice Shelf. Faced with extreme weather conditions, the crew altered their route and headed towards a supposedly hazardous area near Joinville Island. That is when they came across this mysterious formation.
Intrigued, bathymetry specialist Simon Dreutter decided to examine the seabed. As they approached, the team realised it was neither a simple underwater relief nor an iceberg, but indeed an unknown island. The Polarstern came within around 150 metres to carry out detailed mapping using sonar and a LiDAR system (a technique that uses light pulses to map an area).
An island revealing gaps in mapping
Measurements have provided an initial profile of this territory. According to the data, the island stretches 130 metres long, 50 metres wide and rises to 16 metres. For comparison, its surface area is roughly equivalent to that of the White House.
This discovery raises questions linked to climate change. In recent years, sea ice in this region has been retreating, making previously inaccessible areas reachable. The island may therefore have remained hidden for decades—or emerged differently due to environmental changes.
All collected data will feed into the IBCSO database (the International Bathymetric Chart of the Southern Ocean). Once officially named, the island will be added to maritime maps—reminding us that even in the age of satellites, parts of our planet still hold secrets.
