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.

Schepper What are the global impacts of an ice-free Arctic? How will the Arctic develop with increasing climate warming? What does an ice-free Arctic mean for our environment and our society? Researchers [...] surface uplift of the Andes, but also by changes in the oceanic circulation of the adjacent Pacific Ocean. The timing, forcings, and feedbacks of land-ocean coupling and their impact on the past hydroclimate [...] feedback mechanisms in the Arctic affect the phase shift of Arctic surface temperature. The function of each feedback will be quantified for understanding the physical processes of Arctic amplification underlying

ARCGATE The Arctic boundary has been observed over many years to better understand and monitor the exchanges between the Arctic Ocean and its neighboring oceans. The unique geometry of the Arctic—surrounded [...] Polarstern set sail from Tromsø to drift in the Arctic Ocean for a year—trapped in the ice. The goal of the MOSAiC expedition was to study the Arctic, the epicenter of global warming, more closely than… [...] Since the early 20th century hydrographic measurements have been carried out in the Arctic Ocean. Although today the Arctic is a hotspot of climate change, data sampling is still sparse due to the large sea

Recommendations to policy and indicator [...] labs located along the German Baltic Sea. The overall objective is to develop a smart and flexible ocean observation strategy tailored to the specific observation needs of individual stakeholder groups.
