Abstract:	Here we present a magnetic susceptibility dataset from marine sediment core KH21-234-34GC , for its age model. Core KH21-234-34GC was retrieved from the Yermak Plateu (81.2199280 ˚N, 2.3710955˚E ) with a gravity corer at 1011m water depth during cruise KH21-234 . We measured the magnetic susceptibility at 1 cm resolution using a Bartington MS2C loop sensor (Ø 125mm) with a Geotek Multi-Sensor Core Logger (MSCL-S).
Keyword(s):	Arctic; Dinoflagellate; gene copy number; Magnetic susceptibility; Radiocarbon; Sea ice
