Description:
We analyzed 10 samples from the FB2001 depth interval 10-9 m for their Total Organic Carbon (TOC) content. This new data set is supplementary to the existing TOC record of Bauersachs et al. (2014) for the depth interval 145-1 m of the same core. The new samples were measured due to low spatial resolution of the existing TOC data set (~two samples per meter; Bauersachs et al., 2014; doi:10.1016/j.palaeo.2014.06.015) relative to the gamma-ray data (~10 data points per meter), and thus allow for a same-resolution assessment of the gamma-ray/TOC relationship. For the TOC measurements we followed the protocol of Bauersachs et al. (2014). In short, the dried and powdered sediment samples (ca. 30 mg) were pretreated with excess 2M hydrochloric acid (HCl) to remove carbonates, neutralized with distilled water, and again dried at 50 °C for 24 h. Subsequently, samples were measured in duplicates using a CS-Analyser 144DR (Leco Coopeation) at the Institute of Earth Sciences at Heidelberg University with a sample reproducibility of 〈 0.5%.
