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 years.

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 pronounced off the Siberian coast, as a result

is thought to be the warming of 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 [...] 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 main drivers of this development is

After roughly a month underway, in mid-September Polarstern will reach the Norwegian port of Tromsø, where she’ll receive [...] her final preparations for the one-year-long MOSAiC expedition, prior to leaving for the Central Arctic on 20 September.

Today, the research 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 [...] zone, the team of researchers on 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

The Fram Strait essentially forms a connection between Arctic and Antlantic waters and due to the Fram Straits importance for global ocean circulation, it is vital to understand the physical but also [...] connectivity within the Arctic. Particular attention will be placed on assessing the contribution of small cells, imperceptible with traditional techniques, to export processes in the Arctic.

For two months, a good fifty scientific expedition participants will explore the Arctic in transition as sea ice extent reaches its annual minimum in September.

This cross-Arctic flow influences the delivery of both natural substances [...] known as the Transpolar Draft, operates. It also uncovers the various factors controlling this major Arctic surface current, including warmer temperatures which could increase the spread of human-made pollutants
