Quality-controlled XRF data for high 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 24-31 m on the spliced core composite depth scale (CCSF-A) (Lucchi et al., 2026; doi:10.14379/iodp.proc.403.2026) at 3 mm step. Data presented here are described in Gonzalez-Lanchas, Libman-Roshal et al. (under review).

本研究展示了经质量管控的X射线荧光光谱（X-ray Fluorescence，XRF）扫描数据与元素相关性数值，数据来源于综合大洋钻探计划（Integrated Ocean Drilling Program，IODP）第403次航次东弗拉姆海峡古档案区贝尔松德漂移区U1621站位（76°31.3053′N，12°44.3358′E）的深海沉积物岩芯，该站位钻探水深约1700~1800米。该航次实施于2024年6月4日至8月2日期间。岩芯扫描工作于2024年秋季在美国得克萨斯州学院站的IODP墨西哥湾海岸库藏点完成，所用设备为第三代Avaatech型XRF岩芯扫描仪。U1621站位的岩芯以3毫米步长，在拼接岩芯综合深度标尺（CCSF-A）上对24~31米的岩芯段开展扫描（Lucchi等，2026；DOI:10.14379/iodp.proc.403.2026）。本文展示的数据集相关细节详见Gonzalez-Lanchas、Libman-Roshal等（审稿中）。
