Research focuses on areas in the Arctic and sub-Arctic, the Arctic Ocean, the Southern Ocean and Antarctica. The studies include reconstructions of ice sheet dynamics, oceanic circulation and tectonic processes

diversity of the entire plankton community of the Fram Strait (Arctic) is assessed. This data is then applied to forecast future scenarios of Arctic planktonic biodiversity. Recommendations to policy and indicator [...] labs located along the German Baltic Sea. The overall objective is to develop a smart and flexible ocean observation strategy tailored to the specific observation needs of individual stakeholder groups.

layers of the ground, oceanic microseisms can spread over many hundreds of kilometres. It is now well researched how strong storms not only generate large waves, but also increased oceanic microseisms activity [...] other way round: what does oceanic microseisms tell us about the nature of the ice over the course of the seasons? To answer these questions, we use data from our ice-going ocean-bottom seismometers (OBS) [...] microseismics were also recorded, which we are currently analysing. Map of the Arctic and Antarctic.

Scientists from 20 nations collected valuable data about the Arctic, which is crucial for understanding the future climate change. In the SR3 podcast “Aus dem Leben”, Markus Rex reports on his [...] findings of this unique mission. The data obtained provides important insights into the dynamics of the Arctic climate and its global impact. SR3 Podcast: Die größte Arktis-Mission aller Zeiten Christian Haas

Extent of the Arctic ice sheets during the last glacial (Graphic: Catalina Gebhardt) In contrast to the continent Antarctica, the Arctic region consists of a large marine basin. Therefore, Arctic ice sheets [...] Siberia-Chukchi Ice Sheet. During their maximum extent, these ice sheets reached far into the Arctic Ocean, and signs of glacial overprint can be found as far north as at the North Pole. Many studies have [...] sheet is found on Greenland, but in the past, several other ice sheets covered large areas of the Arctic realm.
