ArcticOcean Tiny gypsum crystals can make phytoplankton so heavy that they rapidly sink, hereby transporting large quantities of carbon to the ocean’s depths. Experts from the Alfred Wegener Institute [...] Institute recently observed this phenomenon for the first time in the Arctic. As a result of this massive algal transport, in the future large amounts of nutrients could be lost from the surface waters.
ArcticOcean More melt water is entering the Artic Ocean from the glaciers due to climbing temperatures. In addition, the rivers are carrying large amounts of sediment from thawing permafrost. How the [...] the ArcticOcean will react to such changes is a very big question, which is concerning scientists around the world. Researchers from the Alfred Wegener Institute have now published, together with int
ArcticOcean The Arctic has a serious litter problem: in just ten years, the concentration of marine litter at a deep-sea station in the ArcticOcean has risen 20-fold. This was recently reported in
Nature Scientific Reports The ice-covered ArcticOcean is a more important factor concerning the concentration of the greenhouse gas methane in the atmosphere than previously assumed. Experts from the [...] Research (AWI) report on the newly discovered interactions between the atmosphere, sea ice and the ocean in a recent online study in the journal Nature’s Scientific Reports.
amounts of microplastic in arctic sea ice than ever before. However, the majority of particles were microscopically small. The ice samples from five regions throughout the ArcticOcean contained up to 12,000 [...] patch in the Pacific Ocean, while in turn, the high percentage of paint and nylon particles pointed to the intensified shipping and fishing activities in some parts of the ArcticOcean. The new study has
the ArcticOcean. The four-week expedition, slated to end on 19 July in Tromsø, Norway, will focus on extended ecological fieldwork at the AWI’s deep-sea observatory Hausgarten and at the FRAM Ocean Observing
ArcticOcean The sea ice extent in the ArcticOcean reached its annual minimum of 4.81 million square kilometres on 12 September 2021. As such, the 2021 Arctic sea-ice minimum comes in at 12th place
German Norwegian Ocean Forum From the Arctic to the North Sea: this year’s German Norwegian Ocean Forum was held in Bremen’s Übersee Museum. The spotlight topic of the symposium, which was jointly organised [...] by the AWI, Innovation Norway, and the Royal Norwegian Embassy, was ‘The sustainable future of our oceans’. AWI Director Antje Boetius moderated the event.
We know little about the fish stocks in the central ArcticOcean, and what we know about the local ecosystem is insufficient to ensure sustainable management. In response, in June 2021 the Agreement to [...] to Prevent Unregulated High Seas Fisheries in the Central ArcticOcean – which includes a moratorium on fishing in the region – entered into force. The European Union and nine other countries signed the

They have now published three overview articles on the MOSAiC atmosphere, snow and sea ice, and ocean programs in the journal Elementa, highlighting [...] together. These results present the first complete picture of the climate processes in the central Arctic which is warming more than two times as fast as the rest of the planet - processes which affect weather
