Quality-controlled XRF data for low resolution scans from IODP Site 403-U1621

We present quality-controlled XRF scanning data and element correlation values for marine sediment cores from IODP Expedition 403 Eastern Fram Strait Paleoarchive, Bellsund Drift Site U1621 (76°31.3053′N 12°44.3358′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 403-U1621 cores were scanned for 0-33 m on the spliced core composite depth scale (CCSF-A) (Lucchi et al., 2026, doi:10.14379/iodp.proc.403.2026) at ~5 cm step. Data presented here are described in Gonzalez-Lanchas, Libman-Roshal et al. (under review).
