Shore-based X-ray Fluorescence (XRF), IODP Expedition 395 Site U1554 DOI: 10.5281/zenodo.23404487 X-ray fluorescence (XRF) is a rapid, non-destructive technique for determining qualitative and quantitative changes in chemical composition. Cleaned data: To avoid the use of outliers due to obvious technical reasons, the complete XRF datasets were processed using a MATLAB script XRF_clean_csv.m from Morris et al. (2026) and archived at https://doi.org/10.5281/zenodo.15054747. In the case that there were multiple files covering the same core, they were merged. When duplicate measurements existed for the same stratigraphic level, the most recent measurement was retained. Subsequently, all samples that did not have measurements for all three energy levels (10, 30, and 50 keV) were removed to avoid problems when taking ratios between elements that are potentially quantified using different energy levels. All removed data were saved in a separate file with a comment indicating the reason for removal.
