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 the increasing influence [...] 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 investigates [...] 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 rate of approximately 12

Greenland Ice Sheet Ocean Interaction Investigation of the Interactions Between the Greenland Ice Sheet and the Surrounding Ocean The joint research project GROCE ( Greenland Ice Sheet Ocean Interaction ) is [...] Atlantic, the Arctic Ocean, and Greenland's glaciers need to be studied in greater detail. More information can be found on the project's website. Schematic illustration of the key oceanic and glaciological [...] rapid inflow of warm Atlantic water beneath the glacier tongue. To record the heat transport into the ocean-filled glacier cavity throughout an entire year and observe potential seasonal variations, we deployed

Markus Rex led the MOSAiC-Expedition , the largest Arctic research expedition of our time, during which the research vessel “Polarstern” was frozen in the Arctic ice for a year to study the effects of climate [...] climate change. Scientists from 20 nations collected valuable data about the Arctic, which is crucial for understanding the future climate change. In the SR3 podcast “Aus dem Leben”, Markus Rex reports on his [...] findings of this unique mission. The data obtained provides important insights into the dynamics of the Arctic climate and its global impact. SR3 Podcast: Die größte Arktis-Mission aller Zeiten Christian Haas

Extent of the Arctic ice sheets during the last glacial (Graphic: Catalina Gebhardt) In contrast to the continent Antarctica, the Arctic region consists of a large marine basin. Therefore, Arctic ice sheets [...] Siberia-Chukchi Ice Sheet. During their maximum extent, these ice sheets reached far into the Arctic Ocean, and signs of glacial overprint can be found as far north as at the North Pole. Many studies have [...] sheet is found on Greenland, but in the past, several other ice sheets covered large areas of the Arctic realm. The most important ones were the Laurentide Ice Sheet on North America, the Svalbard-Barents

The objectives of the project are to: (i) Reconstruct (a) mean interglacial [...] to provide a comprehensive description of the present-day Arctic water cycle and related key exchange processes between the atmosphere, ocean, and sea ice, using both instrumental data and climate simulations

The role of clouds and warm air masses from the open ocean for the rapid warming of the Arctic is at the heart of a recent Alfred Wegener Institute project on Svalbard. The researchers are applying a new

ICEDAS was build around the sea ice-ocean model NAOSIM [...] predict the Arctic summer minimum sea-ice extent in September from the beginning of the melting season in May/June on. AWI is participating in the SIO since 2008 by using a coupled sea-ice ocean model (NAOSIM) [...] However, this approach neglects all feedback of the sea ice-ocean system onto the atmosphere. This year (2015) the initial state of the sea ice-ocean model has been constrained by sea-ice observations in a

suitable ice floe, where they will set up the research camp for their one-year-long drift through the Arctic Ocean. Consequently, one of the most important milestones in the expedition has been reached ahead of
