Quality-controlled XRF data for low resolution (alternate) scans from IODP Site 403-U1623

We present quality-controlled XRF scanning data for marine sediment cores from IODP Expedition 403 Eastern Fram Strait Paleoarchive, Bellsund Drift Site U1623 (76°31.8594′N, 12°34.4276′E) drilled at ~ 1,700–1,800 m water depth. Expedition 403 took place between June 4 and August 2, 2024. The cores were scanned in the fall of 2024 using the third generation Avaatech XRF core scanner at the IODP Gulf Coast Repository, College Station, Texas. Site U1623 cores were scanned at ~5 cm step on the spliced core composite depth scale (CCSF-A) from 0 to 30 m CCSF-A from the alternate splice (Lucchi et al., 2026; doi:10.14379/iodp.proc.403.2026). Data presented here are described in Gonzalez-Lanchas, Libman-Roshal et al. (under review).
