Abstract:
Reliable knowledge about the maximum extent of the grounding line during the Last Glacial Maximum (LGM) some 20,000 years ago and its subsequent inland retreat is particularly sparse for the East Antarctic Atlantic margin and its continental shelf. During PS128, 10 piston corers (PC) with a gear length between 15 and 25 m, 39 gravity corers (GC) with a gear length between 3 and 20 m, and 1 Kasten corer (KAL) with a device length of 2 x 5.75 m were used to recover long sedimentary sequences. The gravity core PS128_5-1 was taken along the continental margin off the Ekström Ice Shelf along the East Antarctic Atlantic margin. The overall goal is to enhance our understanding on the late Quaternary processes as well as the evolution of ice-ocean-climate interactions during deglacial warming.
