X-ray computed tomography (CT) greyscale data, laminae counts, highly-branched isoprenoid (HBI) diene data, and X-ray fluorescence silicon and titanium peak areas for IODP Hole 318-U1357B@en

This data publication contains the X-ray computed tomography (CT) greyscale data, manual laminae counts, light laminae sand percent data, highly-branched isoprenoid (HBI) diene data, and XRF silicon (Si) and titanium (Ti) peak areas for IODP sediment core 318-U1357B. IODP sediment core 318-U1357B is ~170 m long and was collected in February 2010 in the Adélie Basin (also known as Dumont d'Urville Trough), offshore Adélie Land, East Antarctica as part of IODP Expedition 318. All data are presented against three different depth scales (csf-a, csf-b, csf-d), and the age model from Ashley et al., 2021 (doi:10.5194/cp-17-1-2021). Descriptions of these depth scales can be found in the associated publication (doi:10.1038/s41561-021-00816-y). These data extend to ~11,380 B.P. X-ray fluorescence Fluorescence scanner data were measured using an AVAATECH XRF core scanner at the JRSO facility, located at the Gulf Coast Repository at Texas A&M University Research Park in December 2010 and April 2011. […]本数据集发布内容包含国际大洋发现计划（International Ocean Discovery Program, IODP）318-U1357B型沉积物岩心的X射线计算机断层扫描（CT）灰度数据、手动纹层计数数据、浅色纹层砂含量数据、高分支类异戊二烯（HBI）二烯数据，以及X射线荧光光谱（XRF）硅（Si）与钛（Ti）峰面积数据。 IODP 318-U1357B型沉积物岩心总长约170米，于2010年2月采自南极东部阿德利陆架海域的阿德利盆地（又称迪蒙·迪维尔海槽），为IODP第318次科学航次的采样成果之一。 所有数据均匹配三种深度标尺（csf-a、csf-b、csf-d），并采用Ashley等人2021年发布的年龄模型（doi:10.5194/cp-17-1-2021）。 上述三类深度标尺的详细说明可参见关联发表文献（doi:10.1038/s41564-021-00816-y）。 本数据集覆盖年代范围至约11380年前（B.P.）。 X射线荧光扫描数据于2010年12月与2011年4月，在位于德克萨斯农工大学研究园区墨西哥湾海岸馆藏库内的JRSO设施中，使用AVAATECH型XRF岩心扫描仪完成测定。[…]
