Abstract:
Sediment core 2018_R2_2F was collected from Sheldon Cove, Antarctic Peninsula (67.55°S 68.27°W) from a water depth of 177 m, on 2018-12-21 as part of expedition JR18003 by the British Antarctic Survey aboard RV James Clark Ross (Sands et al. 2019). The sample was taken with multicorer. The total core length was 25 cm. The dataset with raw data on gamma spectrometry measurements of excess 210Pb and 137Cs, total organic carbon (TOC) content, biogenic silica, and biomarkers is presented by Pieńkowski et al. (submitted to PANGAEA: PDI-37565). Here is presented an age model based on the constant flux constant sedimentation rate (CFCS) model verified with 137Cs downcore distribution. The excess 210Pb and 137Cs data were measured in the Institute of Geology at Adam Mickiewicz University, Poznań, Poland using a gamma detector Canberra BE3830 (Szczuciński, submitted). The model was calculated using serac code (Bruel and Sabbatier, 2020). The obtained average sediment accumulation rate is 1.9±0.4 mm/year.
