In this dataset 14C ages form RV Meteor cruise M157 from the Namibian shelf, gravity core site GeoB23817-12, are presented. Both, depth in core (cm) and the corrected depth below seafloor (cm) are presented for the samples. Gravity core depth was adjusted to extend the paired multicore from the site. The offset was determined visually, based on eight pore water constituent profiles.14C analysis on TOC was carried out in the Carbon Dating Laboratory at Alfred-Wegener-Institute (MICADAS – AWI) in Bremerhaven, Germany, by using accelerator mass spectrometry (AMS). The conventional AMS 14C ages were calibrated using the program: Calib Rev 8.1.0 (Stuiver & Reimer, 1993) with the calibration curve: marine20 (Heaton et al., 2020) and a marine carbon reservoir correction (ΔR) of 146 ± 85 14C years (Dewar et al., 2012).
