The data set contains raw datafiles from an Olympus DELTA Professional X-ray portable spectrometer. The portable XRF data was collected in 2019 on 621 samples from core E-8X, with a sample spacing of ~1 cm across 6 m total core length. The attached file includes a raw data compilation of relative abundances of various oxides, and are utilised as geochemical proxies to decribe bottom water redox changes in the central North Sea during the Paleocene-Eocene Thermal Maximum.
