Multi-proxies from surface sediments in the western Arctic Ocean and its implications for oceanographic changes

Abstract

During the ARK23/3 Expedition (2008) with the German icebreaker RV Polarstern, box core sediments were taken by using the GKG (Giant Box Corer) at 20 geological stations along two transects from the Canada Basin across the central Mendeleev Ridge towards the Makarov Basin and the Lomonosov Ridge in the Eurasian Arctic (northern transect along 80,30N, southern transect one along 77,30N). For this study a total of 20 surface sediment samples were collected on board from the box core sediments in order to investigate recent environmental changes related to global warming in the western Arctic Ocean, and to delineate associated paleoceanographic changes during the Holocene subatlantic period.
