Radiocarbon dates from Yermak Plateau sediment core KH21-234-34GC1

Dataset

DOI

Radiocarbon dates were determined by picking shells of Neogloboquadrina pachyderma at four depths from marine sediment core KH21-234-34GC collected from the Yermak Plateu (81.2199280 ˚N, 2.3710955˚E ) with a gravity corer at 1011m water depth during cruise KH21-234. Accelerator mass spectrometry (AMS) 14C dates from the radiocarbon lab at ETH Zurich, and calibrated ages were calculated used the functions BchronCalibrate:sampleAges and Bchronology:PredictAges from the statistical package BChron (version 4.7.7).
