Biomarker and compound-specific radiocarbon data in sediment cores from the Bering Sea and the Northwest Pacific

The dataset comprises contents, mass-accumulation rates and compound-specific radiocarbon data of several terrigenous biomarkers in sediment cores from the Northwest Pacific (core SO201-2-12KL) and the Bering Sea (cores SO201-2-114KL, SO202/1_18-6 and SO202/1_18-3). The dataset includes contents and...

Description
Summary:The dataset comprises contents, mass-accumulation rates and compound-specific radiocarbon data of several terrigenous biomarkers in sediment cores from the Northwest Pacific (core SO201-2-12KL) and the Bering Sea (cores SO201-2-114KL, SO202/1_18-6 and SO202/1_18-3). The dataset includes contents and mass accumulation rates of high molecular weight n-alkanoic acids, high molecular weight n-alkanes and branched glycerol dialkyl glycerol tetraethers. Moreover, contents and fractional abundances of homohopane isomers are given. Contents are calculated relative to total organic carbon contents and to the dry weight of the sediment. The dataset also contains Paq values and the carbon preference indices of n-alkanoic acids and n-alkanes. Compound-specific radiocarbon data have been obtained from high molecular weight n-alkanoic acids (n-C26:0 alkanoic acid) and high molecular weight n-alkanes (n-C23, n-C27 and n-C29 alkanes). The F14C has been corrected for procedural blanks associated with the isolation of the biomarkers. The data compilation contains the measured (AMS-results) as well as the blank-corrected F14C values. The 14C-data are reported with the 1sigma uncertainty.
