Autonomous underwater robot Ran, owned by the University of Gothenburg, Sweden, Unknown structure discovered under Antarctic ice Mysteriously disappeared in January 2024. The 6-meter-long submersible was deployed in 2020 to explore the glacier known as the “Doomsday Glacier.” Their mission was to map and study the bottom of the Dotson Ice Shelf in West Antarctica.
Ran managed to obtain High-resolution map of the base of the ice shelfrevealing a Complex subglacial landscapeThe new study, published in the journal Nature Communications, shows that the Earth’s rotation has produced a series of landforms with peaks, valleys and dunes, which may have been caused by water flow affected by the Earth’s rotation. This discovery provides important information for studying sea level rise caused by climate change.

Anna Wåhlin, Professor of Ocean Physics, University of Gothenburg The study’s lead author commented: “It’s a bit like seeing the hidden side of the moon.” However, After these discoveries, the submarine signal was lost.which prevented scientists from obtaining all the expected data. Wolin assured that they hope to return with another submarine to complete the investigation.
according to National GeographicLan’s mission involves scanning the ice with a sophisticated sonar system, Over 1,000 km of driving under glaciers and up to 17 km in caves. The data collected showed that in addition to accelerated melting in vertical cracks running through the glacier, Dotson Glacier is melting faster in areas where water is flowing downhill to erode its base.
Located on the remote coast of West Antarctica, the Dotson Glacier defies the region’s harsh climate conditions. The temperature kept dropping below -20°C. The Circumpolar Deep Water Current, a mixture of liquids from the Pacific and Indian Oceans, affects the ice base on the continental shelf differently, causing faster melting on the west side than on the east side.
