On board researchers will investigate a region that is virtually inaccessible in winter, and which is crucial for the global climate [...] urgently needed data on the interactions between the atmosphere, ocean and sea ice, as well as on the ecosystem. Thanks to the collaboration between international experts, the one-year-long ice drift

The Arctic sea-ice extent is the lowest it’s ever been in July since the beginning of satellite observation. The sea-ice retreat is especially [...] Siberia and seriously impacted the sea-ice cover: in the Russian Arctic (the sector from 30 to 180° East), roughly 1 million square kilometres less of the ocean is covered with ice than in the past seven

vessel Polarstern will depart on a seven-week-long voyage to the Arctic, where the onset of summer also marks the beginning of the annual sea-ice melting. Over the past 40 years, the summer sea-ice extent [...] board will investigate how heat fluxes and water layering in the ocean, as well as the characteristics of the ice, interact and influence melting. A further focus of the expedition will be on the warming

conduct studies at a major long-term monitoring station in the Arctic: the AWI’s Hausgarten observatory in the Fram Strait, where experts from various disciplines are investigating all aspects of the ecosystem, from the water’s surface to the ocean depths, in order to determine the impacts of climate change on biodiversity in the Arctic. After roughly a month underway, in [...] one-year-long MOSAiC expedition, prior to leaving for the Central Arctic on 20 September.

In the last few decades, the Arctic sea ice has receded ever further, including increasingly in winter when the extent of sea ice is at its most prominent. One of the [...] Atlantic water that flows from Europe’s Norwegian Sea into the Arctic Ocean, passing through the Barents Sea and the Fram Strait in the process. However, not all the Atlantic water flowing into the

century hydrographic measurements have been carried out in the Arctic Ocean. Although today the Arctic is a hotspot of climate change, data sampling is still sparse due to the large sea ice cover. Yet both the historical and the… Find out more ARCGATE The Arctic boundary has been observed over many years to better understand and monitor the exchanges between the Arctic Ocean and its neighboring oceans. The unique geometry of the Arctic—surrounded by the land masses of North America, Greenland and… Find out more Arctic Long-term

good fifty scientific expedition participants will explore the Arctic in transition as sea ice extent reaches its annual minimum in September. They will explore the biology, chemistry and physics of sea ice as well as the effects of sea ice retreat on the entire ocean system from the surface to the deep sea. Eleven years ago, Antje Boetius was part of the largest ever sea ice minumum in the Arctic [...] Now she is returning with her team to compare the state of the Arctic today - also with the data from the MOSAiC expedition 2019/20.
