Faster Atlantic currents drive poleward expansion of temperate phytoplankton in the Arctic Ocean
Abstract The Arctic marine biome, shrinking with increasing temperature and receding sea-ice cover, is tightly connected to lower latitudes through the North Atlantic. By flowing northward through the European Arctic Corridor (the main Arctic gateway where 80% of in- and outflow takes place), the No...
