Ocean Eddies
In a new study, researchers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) investigated the long-term changes in the Arctic Ocean eddy activity [...] study reveals a remarkable surge in Arctic eddy activity in a warmer climate, a trend that is probably unparalleled when compared to other regions across the global ocean.

icebreaker Polarstern has been drifting through the Arctic Ocean for a year since autumn 2019. Scientists from 20 nations explore the central Arctic over the course of the year on the MOSAiC expedition [...] It goes without saying that the waters of the outer Arctic ice aren’t subject to the same pressure as in the inner ice, let alone the Central Arctic; the floe dimensions are on a different scale, too.

icebreaker Polarstern will drift through the Arctic Ocean for an entire year. During the MOSAiC expedition, experts from 17 nations will investigate the Central Arctic throughout the year. They will overwinter [...] willing to become trapped in the ice of the Arctic Ocean for an entire year? No other region of the Earth has warmed as rapidly over the past few decades as the Arctic; in essence, it is the epicentre of global [...] climate system. What do you hope to accomplish? The Arctic is closely linked to the weather in our latitudes. We can already see climate changes in the Arctic that are shaping our weather and climate. And at

This is documented by many modelling studies, but only [...] sea ice have a significant effect on the energy exchange between the atmosphere and the ice covered ocean.
