This Evening Sees the Start of MOSAiC – the Greatest Arctic Research Expedition of All Time
After a decade of preparations, it’s finally time: this evening at 8:30 p.m. the German icebreaker Polarstern will depart from the Norwegian port of Tromsø. Escorted by the Russian icebreaker Akademik Fedorov, she will set sail for the Central Arctic. On board researchers will investigate a region that is virtually inaccessible in winter, and which is crucial for the global climate. They will gather urgently needed data on the interactions between the atmosphere, ocean and sea ice, as well as on the ecosystem. Thanks to the collaboration between…

Researchers see need for action on forest fire risk
How do humans affect forest fires? And what can we learn from forest fires in the past for the future of forestry? An international team of researchers led by Elisabeth Dietze, formerly at the German Research Centre for Geosciences GFZ in Potsdam and now at the Alfred Wegener Institute - Helmholtz Centre for Polar and Marine Research, now provides new answers to these questions. The research team has shown for a region in north-eastern Poland that forest fires increasingly occurred there after the end of the 18th century with the change to organised…

Follow Polarstern’s drift live on your mobile device
An expedition of superlatives: MOSAiC poses a big challenge to all international scientists involved: The drift of Polarstern will be determined by nature and can only be estimated so far in advance. To allow everyone interested to join this exciting expedition live, the MOSAiC web application will launch on the 20th of September, including all features.

Low sea-ice cover in the Arctic
The sea-ice extent in the Arctic is nearing its annual minimum at the end of the melt season in September. Only circa 3.9 million square kilometres of the Arctic Ocean are covered by sea ice any more, according to researchers from the Alfred Wegener Institute and the University of Bremen. This is only the second time that the annual minimum has dropped below four million square kilometres since satellite measurements began in 1979.

Last activities
This is the last weekly report for PS121, which describes our activities on board during a full week of research. The research activities have continued to go well, and there is already a feeling on board that the expedition is nearing the end.

New Climate Model for the IPCC
Researchers from the Alfred Wegener Institute now, for the first time, feed the results from their global models directly into the Intergovernmental Panel on Climate Change database. The data is particularly interesting because the underlying model, developed at the AWI, depicts the sea ice and the oceans with far greater definition than conventional methods. The results are used by climate scientists and stakeholders around the globe to determine the effects of climate change on humans and the environment.

Working in Hausgarten
A large part of the work and projects that we scientists planned for this expedition are closely related to furthering the long-term observatory HAUSGARTEN, established by the AWI’s Deep-Sea Group 20 years ago, and to supporting the Helmholtz Infrastructure Initiative FRAM (Frontiers in Arctic Marine Monitoring). The long-term observatory Hausgarten is a network of twenty stations in the Fram Strait, whose coordinates are re-visited by us every year in the summer months.

Long-term observations
In the last weekly report, we reported that a long-term observatory such as the HAUSGARTEN is defined by the implementation of regular, standardized investigations at set stations. Because of this, the course of an expedition such as PS121, for which the work is mostly dedicated to furthering the long-term observatory HAUSGARTEN, can be sketched out pretty well before the expedition.
