started in the marginal sea ice zone east of Svalbard, and then set course north into the central Arctic Ocean.The marginal sea ice zone was mostly covered with decaying sea ice and some larger ice-free areas

multidisciplinary investigations in the atmosphere, the water column and at the seafloor of the Arctic Ocean.
[...] 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

have now analysed. Their most important finding: even a short-term influx of warm water into the Arctic Ocean would suffice to fundamentally impact the local symbiotic communities, from the water’s surface [...] Climate Change
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

ecology of Arctic coasts Currently, global warming especially causes strong effects on Arctic ecosystems. We study the consequences of increasing water temperatures on species interactions in Arctic benthic [...] Curr Opin Biotechnol 73, 225-232. doi: 10.1016/j.copbio.2021.07.026. Exciting results Arctic burrowing Effects of Arctic lugworms Find out more Marine heatwaves Do you remember? Find out more Team PIs: Dr [...] benthic coastal communities. From these investigations we predict future scenarios for a warmer marine Arctic ecosystem and its species communites. Evolutionary Ecology Species invasions as a tool to study rapid

category of mid-ocean ridges, accounting for about 15% of the total length of mid-ocean ridges worldwide. 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. Therefore, the formation process of new ocean lithosphere differs at ultraslow spreading ridges from all other ocean basins. Ultraslow ridges

This makes [...] hope to help strengthen the visibility of the ocean in the political arena and support a more integrated approach in which climate, biodiversity, and the ocean are understood as inseparable.” Permafrost Similar [...] having an increasingly significant impact on natural sinks and is weakening the important function of oceans and vegetation on land to store CO₂. “The sinks are tremendously important for us as they give us

Since the early 20th century hydrographic measurements have been carried out in the Arctic Ocean. Although today the Arctic is a hotspot of climate change, data sampling is still sparse due to the large sea [...] climate studies in the Arctic Ocean. Many of the collected data are publicly available, but scattered across different electronic archives. Consequently, scientists working on Arctic climate change have to [...] awi.de The „Unified Database for Arctic and Subarctic Hydrography“ (UDASH) is an attempt to gather all publicly available temperature and salinity data for the Arctic Ocean and to provide them on a high quality
