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

Iceflux - Ice-ecosystem carbon flux in polar oceans In both Polar Regions, areas covered by sea ice are shrinking due to climate warming. What are the consequences of sea ice decline in the Arctic and the Antarctic Ocean? Answering this question is not only important, because sea ice provides a resting ground for penguins, [...] approaches to fisheries management and nature conservation in the Arctic and Antarctic Oceans under environmental change. The research project investigates ice-covered deep-sea ecosystems in the Arctic

What observations in the Arctic and Antarctic are most urgently needed to improve our understanding, models, and predictions of the atmosphere, sea ice, and ocean [...] day! Consider a summer day somewhere in Europe with an Atlantic ocean breeze, and compare it to a day influenced by winds blowing from the continent. The latter will tend to be more strongly affected [...] change, simply because the continents warm more strongly than the oceans. Can we be more specific? Yes! By using a climate model in a special way, where the winds are forced to follow the observed winds,

Accordingly, the development of our planet’s ice sheets and glaciers will to a considerable extent [...] been set in motion that will have lasting consequences. In the Arctic, temperatures are rising twice as quickly as the global average; as a result, the Greenland ice sheet’s loss of mass has accelerated

In May 2019, the ERC PETA-CARB [...] changing. 3D print of a permafrost landscape How do you imagine an Arctic landscape characterized by permafrost? The answer is visualized by a 3-dimensional print of an Arctic landscape in Northeast Siberia [...] exercises in small groups, everyone was gathered for a few Arctic and Antarctic short movies and a final discussion and Q&A session.

FLO CHAR The project "Fluxes from Land to Ocean: How Coastal Habitats in the Arctic Respond" (FLO CHAR) focuses on the biogeochemical effects of climate change on the most rapidly evolving ecosystem on Earth, the shallow Arctic coastal environment. Background of Project FLO CHAR: Accelerated climate change in the Arctic is dramatically altering terrestrial [...] and infrastructure on which local communities rely. Particularly Arctic coastal waters and shelves are impacted strongly as they sit at the interface between the warming land and ocean. At the same time
