Arctic sea ice reflects solar radiation, slows global warming and influences global ocean and atmospheric circulation. Due to limited observations, reanalysis data is used, which can be biased. A research team led by AWI researcher Akil Hossain has developed an AI model to correct these biases.

What happens on the deep Arctic seafloor when glaciers retreat and sea ice disappears? A new AWI study reveals: As Arctic glaciers become increasingly unstable, more icebergs break off and drift through the ocean. Carrying rocks and sediment, these icebergs create new seafloor habitats as they melt.

Thawing permafrost, erosion and rising sea levels are causing permanent changes to Arctic river deltas. This puts important carbon sinks and unique ecosystems under increasing pressure. In a study, AWI researchers are investigating the impact of these changes on the Arctic and the global climate. 🌍
