investigating the impact of altered ocean circulation and ocean warming on glacial calving on the coast of Greenland and on the ocean-sea ice system in the Arctic Ocean. In the past six years he has led [...] regions of the world’s oceans. He began his career by investigating deep-ocean currents in the tropical Atlantic, and completed his doctorate at the GEOMAR Helmholtz Centre for Ocean Research Kiel and Kiel [...] led five major research expeditions along the east coast of Greenland and in the Arctic Ocean, including the third leg of the international MOSAiC expedition on the research icebreaker Polarstern in 2020

AWI scientist Sinhué Torres-Valdés observed the nutrient chemistry of the Arctic Ocean on an expedition as part of the PEANUTS project (Primary production driven by Escalating Arctic NUTrient fluxeS). The SCRIPPS Institution of Oceanography led the expedition in 2018. The results have now been published in a paper in the journal Nature Communications. The PEANUTS project is funded by the Changing Arctic Ocean Program (CAO).

study of Arctic Ocean surface sediments (Fig. 2; Xiao et al., 2015 ). During the last years, a large number of IP 25 /PIP 25 studies have been carried out to reconstruct the late Quaternary Arctic sea-ice [...] Polar sea ice variability - Arctic Our ability to quantitatively reconstruct Arctic paleo-sea-ice distributions has been greatly improved by a novel biomarker approach which is based on the determination [...] SeaIce4). In order to fully establish the IP 25 approach as key proxy for the reconstruction of past Arctic Ocean sea-ice conditions, however, more ground-truth data related to the synthesis, diagenesis, and

The influx of warmer water masses from the North Atlantic into the European marginal seas of the Arctic Ocean plays a significant role in the marked decrease in sea-ice growth, especially [...] evident a year later, when the ice has drifted towards Greenland via the North Pole and leaves the Arctic through Fram Strait. This study also includes data from the MOSAiC expedition.
