Description: The dataset comprises radiocarbon dates of planktic foraminifera and hydrogen and carbon stable isotopic compositions (δD and δ13C) of high molecular weight n-alkanoic acids (leaf-wax biomarkers) in a sediment core from the eastern Mediterranean (GeoB7702-3). The records cover the past 18 ka. In this dataset new radiocarbon dates of planktic foraminifera are combined with previously published radiocarbon dates of planktic foraminifera (Castañeda et al., 2010; doi:10.1594/PANGAEA.736913) in order to produce a new age depth model. Next to a compilation of all radiocarbon dates used for the updated chronology the new age-depth model for the core are provided. The δD signature of high molecular weight n-alkanoic acids is reported as measured values (corrected for methylation (δD)) and as ice-volume corrected values (δDwax). Moreover, δD is converted into δD of precipitation by correcting it for past changes in the relative contributions of C3 versus C4 plants and ice-volume changes (δDp-vc-ic). In addition to δDp-vc-ic values of high molecular weight n-alkanoic acids we include the δDp-vc-ic of high molecular weight n-alkanes (leaf-wax lipid). The latter is calculated based on original δD data from Castañeda et al. (2016) (doi:10.1594/PANGAEA.858559). The reported δ13C-values of high molecular weight n-alkanoic acids are corrected for methylation (δ13Cwax). Based on δ13Cwax the relative contribution of C4 plants to the pool of high molecular n-alkanoic acids is calculated (%C4). It is also provided for high molecular weight n-alkanes which is calculated using original δ13Cwax-data from Castañeda et al. (2016) (doi:10.1594/PANGAEA.858559). Next to the isotopic compositions we also report concentrations of n-akanoic acids and n-alkanes.

Description: This dataset contains bulk geochemical information (TOC, S, Tmax, Hydrogen and Oxygen Indices), relative and absolute abundances of selected plant wax and bacterial hopanoid biomarkers as well as stable carbon and hydrogen isotope signatures of selected compounds. Samples were analysed with a Leco C/S analyser, a Rock-Eval 6 pyrolysis unit, a gas chromatograph-triple quad mass spectrometer and gas chromatograph isotope ratio mass spectrometer (for d13C and d2H). The samples originate from two onshore outcrops at the Stenkul Fiord (Ellesmere Island) and are mostly coal samples of the lignite thermal maturity stage. The age of the samples are Paleogene and cover the Paleocene Eocene Thermal Maximum (PETM; Margaret Formation), and they were taken in 2017 (BGR CASE 19 expedition). The data were generated to reconstruct the terrestrial paleovenvironment in this high-latitude setting. More information on the studied sections can be found elswhere (Reinhardt et al., 2022).
