Marine heatwaves are becoming more frequent and intense. The Arctic Ocean also suffers from this development: The absence of sea ice will lead to more extreme fluctuations in ocean temperatures, with [...] heatwaves will also become much more intense and frequent in the Arctic in the 21st century. With drastic consequences for the ecosystem. The researchers published their findings in the scientific journal

Marine Geology curates and archives sediment cores from both polar oceans which were taken by RV Polarstern since 1983. The collection comprises more than 4000 cores from gravity, piston, kastenlot and [...] the AWI repository. Lacustrine sediments cored from lakes in the Arctic and Antarctic are archived by the section Polar Terrestrial Environmental Systems at AWI Potsdam. Cores are stored at 4°C and an

Sea Ice Broad expanses of the Arctic Ocean and the Southern Ocean in the Antarctic are covered in sea ice. The ice plays a vital role in our climate system and is an [...] when seawater freezes; this most frequently takes place in the Arctic and Antarctic. Depending on the season, the ice covers greater or lesser parts of the ocean. In the Northern Hemisphere, the ocean [...] the Arctic Ocean and the atmosphere, the ice is melting earlier in spring and freezing later in autumn. In September 2012, the Arctic sea-ice

Even in the most remote parts of the ocean, like the polar regions or the bottom of the deep sea, we can find large amounts of [...] plastic debris end up? A great deal of the debris in and on the ocean ends up on beaches or the ocean floor. Especially deep-sea trenches have essentially become deposition sites for large amounts of debris. Currents transport plastic debris through the ocean, allowing it to accumulate even in remote areas like the Arctic. Unlike beach debris, the plastics in the ocean cannot be readily
