This requires integrating [...] extremes as well as sea level change for the benefit of society. We are involded in the subtopics: Subtopic 2.1 Warming climates Subtopic 2.2 Variability and extremes Subtopic 2.3 Sea level change Subtopic [...] l Oscillation (AMO) significantly influences global climate patterns through its impact on North Atlantic Sea surface temperatures, yet the mechanisms driving its representation in climate models, particularly

summer insolation forces meltwater discharge from the ice sheets into the polar seas which subsequently enhances formation of sea ice during the winter. In the second case, growth of continental ice enhances [...] Heinrich events and their signature in the North Atlantic. Dear Hartmut, we have largely benefited from your unexpected finding of ice rafted debris in the North Atlantic Ocean. It inspired many researchers [...] our section.

It can also be deflected horizontally [...] with light to moderate sea ice cover. It was used for the first time during the Polarstern PS131 expedition and allowed the collection of valuable data in the marginal ice zone north of Svalbard. Further

The results were published in the [...] There is a greater variety of hydrothermal systems in the deep sea than previously assumed. This is the result of a recent study lead by MARUM – Center for Marine Environmental Sciences and the Faculty
