to investigate impactsof past and future climate changes in the Arctic. Since permafrost is usually not visible at the earth’s surface and only few measurement sites exist, models are also important to [...] , permafrost models give us insights into the evolution of Arctic landscapes and help us understand how these unique ecosystems respond to natural and human-caused disturbances. Permafrost models [...] interactions between permafrost, vegetation, snow, lakes, and the Arctic ocean. Furthermore, we use our models to gain insights into important ecosystem functions such as the water and carbon cycles. We

Wegener Institute has operated a long-term observatory in the Arctic deep sea: the HAUSGARTEN. Located between Greenland and Svalbard, it is where researchers investigate natural and climate-change-related changes in a polar, marine ecosystem – from the ocean’s surface to the seafloor, 5,500 metres below. Many of the observatory’s stations are located below the sea ice, while its autonomous

Sea Ice Thickness - Mass Balance The Arctic sea ice extent and thickness have undergone dramatic changes in the past decades: The summer sea ice extent is declining at an annual [...] atmospheric greenhouse gas loading scenarios. The mass balance of Arctic sea ice is therefore determined not only by changes in the energy balance of the coupled ice-ocean-atmosphere system but also by [...] influence of dynamic effects. One aspect of the mass balance of Arctic sea ice are changes of ice volume export rates through major gates of the Arctic, such as Fram Strait. The Sea Ice Physics group
