[...] the early evening on the 13th June 2016 we set sail for the long passage from Bremerhaven to the Arctic. We, that is 45 crew members and a total of 51 scientists, engineers, technicians and students with

The warming of arctic waters in the wake of climate change is likely to produce radical changes in the marine habitats of the High North. This is indicated by data from long-term observations

Arctic Ocean
On the seafloor of the shallow coastal regions north of Siberia, microorganisms produce methane when they break down plant remains. If this greenhouse gas finds its way into the water, [...] these coastal waters. As a result, the gas can be transported thousands of kilometres across the Arctic Ocean and released in a completely different region months later. This phenomenon is the subject of [...] current issue of the online journal Scientific Reports. Although this interaction between methane, ocean and ice has a significant influence on climate change, to date it has not been reflected in climate

Their expertise is not just of interest to the scientific community and the media; their advice [...] to sensitise the next generation to global litter problems. The extent of litter pollution in our oceans is alarming, especially since we still know so little about its effects on marine organisms and habitats

Since ultraslow ridges are located in the Arctic Ocean and the stormy Southwest Indian Ocean and are therefore [...] Ultraslow spreading mid-ocean ridges At mid-ocean ridges, the lithospheric plates move apart at rates of about 5-150 mm/year and new oceanic lithosphere is continuously formed. At low spreading rates of [...] making its way to the ocean floor through a cold, thick lithosphere.
