In parallel, Thomas Jung is investigating in various projects how the climatic changes in the Arctic affect extreme weather events in Central Europe and what impact today’s heat waves or heavy rainfall

On board researchers will investigate a region that is virtually inaccessible in winter, and which [...] 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 international experts

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.
