The Wadden Sea forms a transitional habitat between land and sea. The shallow depth and constant exchange with the adjacent North Sea create a very special geological space. The Wadden Sea Ecosystem Our [...] oyster: in the early 20 th century, intensive fishing had seriously depleted oyster stocks in the North Sea. To gain a better understanding of the endangered species’ living conditions and explore options [...] From the Beginning to the Present The Wadden Sea Station on Sylt – Germany’s northernmost research facility – can look back on a 100-year history and a long tradition as part of the Biological Institute

properties of the atmosphere, sea-ice and the polar oceans, and feedbacks between these domains play an important role in global climate. At the same time, the seasonal evolution of sea-ice dominates biological [...] and analysis phase will take place between 2027 and 2030, with joint field campaigns on land, at sea and in the air.… Find out more GROCE The joint research project GROCE (short for Greenland Ice Sheet [...] Find out more FISP The loss of mass from the Antarctic Ice Sheet and the associated rise in global sea levels are linked to reduced support from ice shelves and the subsequent acceleration of glaciers.

As long as interior mixing processes are weak, this vertical structure persists and the sea ice is protected [...] heat around the globe. In the Arctic, the role of internal waves is less clear. This far north and under a strong sea ice cover, only few internal waves are generated. Due to global warming, however, the [...] continues to drive sea ice decline, internal wave generation and mixing could increase such that enough heat from the Atlantic Water is fluxed toward the surface that even more sea ice melts.
