speed of several millimetres to centimetres per year (plate tectonics). So-called mid-oceanic ridges run through the oceans. In these zones magma rises from the Earth’s interior to the surface, cools down there [...] magma again. 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

Topic 2: Oceans and Cryosphere in Climate How do oceans and the cryosphere drive climate change, and how can we better predict future [...] profound changes, with significant impacts on humanity. Central to these changes are the polar regions, oceans, and coastal and shelf seas, which play crucial roles in regulating the Earth's climate and supporting [...] ty and have a critical influence on both regional and global climate by affecting sea-ice cover, ocean circulation, atmospheric conditions and finally coastal areas.

This is associated with a comparatively high [...] societal options for action. With our research on changes in the atmosphere, the cryosphere, the ocean and the coast, corresponding feedback mechanisms as well as the consequences of climate change for [...] habitats and species and the overall significance of the UN goals for sustainable development for oceans and polar regions and to keeping these issues present in the public consciousness. A particular challenge

systems across the Arctic and Antarctic, using research vessels, such as the icebreaker Polarstern , observatories, aircrafts, and satellites to capture the evolving dynamics of the ocean, atmosphere, sea [...] climate is shaped by intricate physical and biogeochemical processes in the atmosphere, cryosphere, and ocean. Understanding these processes – especially in the rapidly changing polar regions where the changes

nearshore food-web through the release of sediment and organic matter to the ocean. Survey-like studies on coastal erosion in the Arctic exist, but a comprehensive understanding of local processes is lacking [...] Coastal Permafrost Profile About 34% of the world's coasts are affected by Arctic permafrost and are particularly sensitive to climate change. The frozen bluffs lose the cohesion provided by the permafrost [...] seawater and are instantly washed away by incoming waves. In the course of the expected warming in the Arctic, which is estimated to be about two to four times as high as the global average, favourable conditions

Due to its high salinity, the Southern Ocean’s water doesn’t freeze at zero degrees [...] Southern Ocean. In winter, sea ice up to 1.5 metres thick forms atop the water. Air temperatures over the sea ice can easily reach minus 30 degrees Celsius. Given its high salinity, the ocean’s water only [...] ice? Similar to the Arctic, the Antarctic is home to numerous species that have adapted to life in, on or below the ice. For example, of the six seal species native to the Southern Ocean, only the Antarctic

An entire year trapped in the Arctic ice MOSAiC - Multidisciplinary drifting Observatory for the Study of Arctic Climate It is the largest-scale Arctic research expedition of all time: From autumn 2019 [...] research icebreaker Polarstern drifted through the Arctic Ocean, trapped in the ice. Participants from institutions from more than 20 countries studied the Arctic over the course of the year. They overwintered [...] other region has warmed as much as the Arctic in recent decades. Therefore, the MOSAiC project's goal was to reach a better understanding of the influence that the Arctic has on the global climate. Hence, it
