Abstract:
Sediment cores from the East Antarctic Continental Shelf from the Polarstern Cruise PS128 'EASI-1' in 2022. These cores have been taken with Kiel-type gravity corers from the outer continental shelf offshore the Ekström Ice Shelf (easternmost Weddell Sea). They are used to contribute to a reliable spatiotemporal framework of past grounding line dynamics since the LGM and to establish detailed facies analyses for describing past environmental change across the shelf. For some of the cores, AMS 14C and RPO (ramped-pyrolysis oxidation) dating has been done at the MICADAS Lab at the Alfred Wegener Institute, Bremerhaven, Germany.
