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.

While with the coupled AWI climate model global climate simulations are possible, NAOSIM only depicts the processes in the Arctic and the North Atlantic. “Altogether [...] Weather models mainly take into account the physical processes in the atmosphere. The processes in the ocean, such as large currents or the development of sea ice, are not taken into account in detail. But they

To date we still don’t [...] Which types of plastic litter are there in the ocean? Question 2: Where does the plastic waste come from? Question 3: How much plastic litter is there in the ocean? Question 5: What are garbage patches?
