improve the understanding of polar atmospheric processes and their interactions with sea ice and ocean in the global context. We combine long term observations from ground stations and innovative measurements [...] improving the representation of polar processes in regional to global scale climate models. We run the Arctic research station AWIPEV on Svalbard and the meteorological and atmospheric observatory at the Antarctic

Observatory to investigate the effects of global warming on the Arctic deep sea. Since 2012, she has been focusing on plastic pollution in the oceans. She has published the reference book 'Marine Anthropogenic

A region in which new seafloor continuously forms is, for instance, Gakkel Ridge in the Arctic. This is a submarine mountain range whose northern foothills extend from the northeast tip of Greenland

snow isn’t just snow. There are clear differences if you compare, e.g., the Arctic and Antarctic. While the snow on the Arctic sea ice is completely melting over the course of the year, and so-called meltwater [...] effectively it insulates, and as such reduces the transfer of heat from the ocean to the atmosphere. However, the less warmth the ocean gives off, the thinner the sea ice remains. Therefore the snow not only [...] 23.09.2019 Scientists Prepare for Year-Long Expedition to Arctic Center Find out more > EOS | 06.09.2019 Light Permeates Seasonally Through Arctic Sea Ice Find out more > Dialogue & Lectures Lecture | 09
