Abstract:
The data compiles the results of radiocarbon dating. Subsamples (n=4) of the freeze-dried bulk material of the deeper part of the short core EN18232-1 were dated in the radiocarbon analysis laboratory at AWI Bremerhaven. 14C was analysed by using an accelerator mass spectrometer (AMS) MICADAS (MIni CArbon Dating System) (Mollenhauer et al., 2021). Obtained 14C ages were calibrated with the IntCal20 14C calibration curve (Reimer et al., 2020), using the CALIB Radiocarbon Calibration Program (CALIB REV 8.2)(Stuiver & Reimer, 1986, 1993).
