Abstract:
This dataset contains catchment-weighted turnover times of soil carbon (τsoil) and soil mean carbon ages (0-100m soil depth) for the Nile River watershed over the past 18,000 years. This data is calculated from compound-specific radiocarbon analysis of leaf-wax biomarkers (high molecular weight n-alkanoic acids) in marine sediment core GeoB7702-3, eastern Mediterranean Sea. The radiocarbon data are given as the reservoir ages offset between the biomarkers and the atmosphere which represents the 14C-age of the biomarkers at the time of deposition in the marine sediments at the core site.
