Description
Summary:The Northeast Greenland continental shelf became one of the tipping elements in our climate system. Ongoing mass loss of the Greenland Ice Sheet, intensive sea-ice loss, the influence of warm, recirculating Atlantic Water towards the inner shelf, intensive bottom-melting at the underside of local marine-terminating outlet glaciers, glacier retreat and ice-sheet disintegration plays a fundamental role in terms of ongoing anthropogenic warming. Marine sediment Core PS100/270 was recovered aboard the RV Polarstern cruise PS100 in 2016 directly in front of 79NG on the inner NEG continental shelf (79°29.83'N, 18°8.40'W) in a water depth of 424 m. Chronology of the 9.51 m long Core PS100/270 is based on 13 AMS 14C ages, measured on benthic foraminifera. Sediment samples of Core PS100/270 were investigated to analyse microfossil assemblages, biomarker and bulk parameter proxy data. Additionally, the lithology, x-ray radiographs and geophysical properties (wet bulk density and magnetic susceptibility) were ...
