. It also uncovers the various factors controlling this major Arctic surface current, including warmer temperatures which could increase the spread of human-made pollutants. The Transpolar Drift carries [...] suspended matter from the Siberian shelves across the central Arctic towards the Fram Strait channel, which connects to the Nordic Seas. This cross-Arctic flow influences the delivery of both natural [...] and heavy metals – from Siberian river systems into the central Arctic and the North Atlantic. This material affects Arctic biogeochemistry and ecosystems, while the fresh water itself alters ocean

ArcticROOS will promote, develop and maintain operational monitoring and forecasting of ocean circulation, water masses, ocean surface

As a contribution to the ArcSolution project we will simulate the oceanic advection of pollutants from their sources with a global version of the sea-ice-ocean model FESOM2 with about 7 km spatial resolution in the Arctic and Nordic Seas. Atmospheric predictions from climate models of the [...] changing Arctic climate and the impacts of oceanic and atmospheric processes under a range of plausible scenarios. Doing so, we aim to provide not

The current, relatively weak mixing processes in the interior Arctic Ocean are the life insurance for its sea ice: The waters [...] We aim to shed light on the various feedback processes between Arctic internal waves and sea ice and the ramifications for ocean dynamics in the Arctic and beyond. Climate models do not resolve the [...] wave-driven mixing is not represented in a physics-based way in the Arctic. We will close this research gap and thereby contribute to improving climate projections. News How waves stir up the Arctic Ocean

Changes in the circulation freshwater between Arctic Ocean and subpolar North Atlantic In RACE we study the variability of the freshwater storage in the Arctic Ocean and the subpolar North Atlantic. We use observations and model simulations of the ocean and the sea ice to understand the underlying processes. Here you find the project website . Contact: Dr. Benjamin Rabe (Phys.
