The overall objective is to develop a smart and flexible ocean observation strategy tailored to the specific observation needs of individual stakeholder groups.

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
