Abstract
Calibrated ages of sediment core based on foraminifera from the northern Barents Sea. This dataset is part of the unpublished article “Deglacial and post-glacial sedimentary processes and environments south of Kvitøya». Benthic foraminifera were collected from 1 cm slices of gravity core KH18-10-08GC1. Determination of radiocarbon ages of 7 foraminifera-samples containing the species Cibicides lobatulus, Elphidium excavatum, Nonionella Labradorica and Cassidulina neoteretis were performed at the LARA laboratory at the University of Bern. All radiocarbon ages were calibrated using the calibration program Calib Rev 8.2 (Stuiver and Reimer, 1993) and the Marine20 calibration curve (Reimer et al., 2020). All the dates have been calibrated for a low depletion Present Day (PD) scenario (Heaton et al., 2023) using a local 〖ΔR〗_Hol^20 value of -61 ± 31 years (Pienkowski et al., 2020). The lowermost date can potentially also be calibrated for a maximal depletion Glacial Scenario (Heaton et al., 2023). This will be discussed further in the unpublished article “Deglacial and post-glacial sedimentary processes and environments south of Kvitøya».
