These datasets describe samples taken from yedoma and thermokarst deposits in Baldwin Peninsula (BAL), West-Alaska. Five locations were sampled: a yedoma exposure (B2), three drained thermokarst lake basin (DTLB) exposures (B2, B3 and B4) and a thermokarst lake (UPL1-L1). The collection and analysis of the samples are described in Jongejans et al. (in review). The first four datasets include sampling dates, type of environment (active layer, permafrost or thermokarst lake), site coordinates and the depth from the sediment surface.
Dataset presents sedimentological (ice content, bulk density, grain size) and biogeochemical parameters (TC, TN, TOC, C/N, d13C) of the yedoma (B2), DTLB (B3, B4 and B5) and thermokarst lake (UPL1-L1) sediments.
Dataset presents the radiocarbon ages (with standard deviation ±) from chosen samples taken from the yedoma (B2), DTLB (B4) and thermokarst lake (UPL1-L1) sediments. Calibrated and rounded calibrated ages are presented. Calibrations were performed according to Stuiver et al. (2017) using CALIB 7.1 software and the IntCal13 calibration curve.
Dataset presents n-alkane data from the yedoma (B2) and DTLB (B4) sediments. Concentrations per n-alkane, as well as total n-alkane concentration are presented. Also, two indices (CPI and ACL) are presented that were calculated from the n-alkane concentration.
Dataset presents GDGT data from the yedoma (B2) and DTLB (B4) sediments. Concentrations per structure, as well as total brGDGT and crenarchaeol concentrations are presented.
