Thick sections of recovered sediments and sedimentary rock from Expedition 369 sites (for an overview and site locations, please see the Expedition 369 summary chapter [Huber et al., 2019a]) were scanned on two X-ray fluorescence (XRF) core scanners (Avaatech B.V., Netherlands) hosted at the Gulf Coast Repository (College Station, TX, USA) from February through May 2018. These measurements were part of a new routine scanning program implemented by the International Ocean Discovery Program’s JOIDES Resolution Science Operator (IODP-JRSO), and were undertaken primarily to aid in splice refinement and to guide sampling at the post-expedition sampling party (18–22 May 2018). Additionally, the XRF scanning datasets are valuable themselves and are planned for inclusion in post-expedition publications in the open literature (see the Expedition-related bibliography at

Scientifically, measurement priorities were to scan intervals of high paleoclimatic importance (e.g., Oceanic Anoxic Events), spliced intervals from sites U1513, U1514 and U1516 to help refine the shipboard stratigraphy, and those with apparent cyclicity (sites U1512, U1513, U1514 and U1516) to aid astronomical tuning. Site U1515 was the only site not to have any sections scanned. Some of the intervals covered for paleoclimate included suspected OAEs 1d and 2 (Cenomanian–Turonian boundary), the Paleocene–Eocene Thermal Maximum (PETM), Eocene hyperthermals, Eocene–Oligocene boundary and Neogene sections. Full details of these intervals (visual expression, physical properties, geochemical characteristics and paleontological descriptions) can be found in the individual Proceedings volume site chapters (Huber et al., 2019b, 2019c, 2019d, 2019e).
