This may partly explain why Vibrio monitoring efforts in the German Bight are altogether lacking [...] traffic, pollution & eutrophication from various sources, and recently, the set-up of wind farms at sea. With our focus on microbes these two aspects, climate change and anthropogenic pressure are under

Eleven years ago, Antje Boetius was part of the largest ever sea ice minumum in [...] set off from Tromsø, Norway, towards the North Pole. For two months, a good fifty scientific expedition participants will explore the Arctic in transition as sea ice extent reaches its annual minimum in [...] in the Arctic and its consequences for life in the deep sea. 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.

Their occurrence and rate [...] marine areas. In cooperation with the Schleswig-Holstein State Office for the Environment, the AWI North Sea Office has compiled an overview of all known introduced species in German marine areas: “Neobiota

Their concentrations vary due to inlets found along the course of the river, but also due [...] microplastic particles, nutrients and climate gases found in the river change on their way to the North Sea.

international team of researchers is investigating the coupling between sea ice, the ocean and its life, including within the deep sea. So far, the Arcwatch-1 expedition, launched on August 3, 2023, has delivered

Their [...] significant changes compared to previous expeditions. On 7 September 2023, Polarstern reached the North Pole, and on 20 September there was the world's first livestream of an ROV under-ice dive from the

Of special interest will be the interrelationship between sea-ice cover, meltwater [...] Arctic sea ice variability, a crucial indicator or ‘canary in the coal mine’ for the Arctic and global climate state. If greenhouse gas emissions remain unchecked and further increase, summer sea ice loss [...] draining into the Amundsen Sea, the Pine Island and Thwaites glaciers. If these two major ice streams continue retreating into the deep inner basins, they would raise the global sea level by ~1.5 m. In order
