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).2.37109554281.21992801European Research Councilhttps://doi.org/10.13039/501100000781101118519Into the Blue - Resolving past Arctic greenhouse climate (i2B)Horizon 2020https://doi.org/10.13039/501100007601818449Genetic information for Arctic sea ice study
