warm water from the Atlantic flows into the European North Sea and ultimately into the cavern under the glacier tongue, where it melts the ice from below. Their study findings, which have just now been [...] Communications , pave the way for more precise projections on the future of the Greenland Ice Sheet and increasing sea level rise from global warming. [...] Greenland's ice-sheet The Nioghalvfjerdsfjorden Glacier – also known as the 79° North Glacier – on the northeast coast of Greenland flows directly into a fjord, where it forms an 80-kilometre-long tongue
to a significantly increased melting rate of the Filchner Ronne Antarctic ice shelf, resulting in a substantial rise in global sea levels. [...] to result in significantly increased deep water temperatures in the Filchner Trough in the Weddell Sea in Antarctica, reports a modelling study lead by researchers of the Alfred Wegener Institute and published
The North East Greenland Ice Stream transports enormous amounts of ice from the heart of the island to the sea and thus also influences global sea levels. An international research team led by the Alfred [...] of Greenland around 2,000 years ago. The study, which opens up new possibilities for research into ice sheets, was recently published in the scientific journal Nature Communications .
Analyses suggest that Ice Age hunters built this structure around 11,000 years ago to hunt reindeer. It is the first time that such a hunting structure has been discovered in the Baltic Sea region, the group
At the AWI ice laboratories, part of an ice core from the North Greenland Ice Stream (NEGIS) is currently being tested. The core was collected during “EastGRIP”, a joint project involving several international [...] allowing them to penetrate the entire ice stream and reach the rocky substrate below. The analysis of the ice core is to yield new insights into the behaviour of ice streams and improve our grasp of how [...] how they could contribute to future sea-level rise. Another goal is to record past climatic conditions beneath the northeast section of the Greenland Ice Sheet. Numerous laboratories around the globe plan
Christchurch, New Zealand, for Antarctica to drill up to 200 metres into the seabed beneath the inner Ross Ice Shelf. The team aims to obtain geological records of changing sediments that reflect environmental [...] West Antarctica's past, allowing us to learn more about Antarctica's potential future contribution to sea level rise.
the Southern Ocean. A study by former AWI researcher Henrik Sadatzki reveals that the Antarctic seaice cover declined substantially at the transition from the last glacial period to the current warm period
measured seaice thickness and properties, recorded the currents and chemical properties of the ocean and investigated life in and under the ice, in the open water and at the bottom of the deep sea. Their [...] reached the North Pole, and on 20 September there was the world's first livestream of an ROV under-ice dive from the Central Arctic.
international team of researchers is investigating the coupling between seaice, the ocean and its life, including within the deep sea. So far, the Arcwatch-1 expedition, launched on August 3, 2023, has delivered [...] unusual ice drift, which is affecting communities under the ice. In addition, the team has discovered an amazing biodiversity at a previously unmapped seamount at 1500 meters depth, under the ice.
