Abstract:
The data set contains raw datafiles from a Neptune Plus MC-ICP-MS mass spectrometer in order to obtain molybdenum isotopes and isotope ratios (100Mo, 98Mo, 95Mo). The ICP-MS data was collected in 2020 on 18 samples from core E-8X, and the sample spacing varied greatly based on the intervals of interest: ~35 cm during the pre Paleocene-Eocene Therman Maximum (PETM), ~35 cm during the main phase and recovery phases, and ~3 cm around the carbon isotope excursion (CIE). The attached file includes a raw data compilation of molybdenum isotope ratios which are utilised to decribe bottom water redox changes and water circulation in the central North Sea during the Paleocene-Eocene Thermal Maximum.
