| contents | Sediment Core PS115/2-2 was recovered from the Amundsen Basin in 3600 m water depth at the eastern flank of the Gakkel Ridge during Polarstern Expedition PS115/2 in 2018 (Stein, 2019). The well-dated core is used to reconstruct in detail the interrelationship between ice-sheet dynamics and organic carbon burial in the central Eurasian Basin during the last 430 kyr, and to correlate marine and terrestrial records of the Eurasian Ice Sheet (EIS) history. Our age model, a fundamental prerequisite for any kind of paleoclimatic reconstruction, is based on records of the inclination and relative paleointensity (RPI) of the Earth's magnetic field approved by rock magnetic data, 230Th and 231Pa excess (230Thex and 231Paex) records, and AMS14C ages. The listed tie points are used to develop the age model and to calculate linear sedimentation rates. For details and methods, we refer to Stein et al. (this paper). |
