Research Meltwater pools on the Arctic Ocean. The polar regions and oceans are central drivers of climate-related processes. (Photo: Stefan Hendricks, Alfred-Wegener-Institut) Oceans cover seventy percent of [...] by their fascinating diversity, they hold resources essential to humanity’s survival. Not only do oceans and their ecosystems fulfil a key role in the control of global environmental processes; they are [...] cities and claims to usage rights are often concentrated, the vast and unpopulated regions in the Arctic and Antarctic are also transforming. Not only are the polar regions highly sensitive to climatic
