Radiograph scans of sediment cores collected from the Semenov Hydrothermal Field region of the Mid-Atlantic Ridge during the RRS James Cook cruises JC224 (March - April 2022) and JC254 (October - November 2023)

Whole-round and split archive halves of sediment cores collected from the Semenov Hydrothermal Field region of the Mid-Atlantic Ridge during the RRS James Cook cruises JC224 (March - April 2022) and JC254 (October - November 2023) were imaged using the Geotek ScoutXcan X-ray imaging system at the British Ocean Sediment Core Research Facility (BOSCORF). Using linear and rotational 2D imaging capabilities of the system, 2D multi-angle X-ray radiographic images allow more detailed core descriptions by revealing sedimentary structures and density contrasts across different lithologic units. The data were collected as part of a PhD project funded under NERC's Ultramafic-hosted mineral Resource Assessment (ULTRA) project, grant reference NE/S004068/1, and the sediment cores are currently stored at the BOSCORF for long-term preservation.

2022年3月至4月、2023年10月至11月期间，在RRS"詹姆斯·库克"号（RRS James Cook）航次JC224与JC254中，于中大西洋脊（Mid-Atlantic Ridge）谢苗诺夫热液区（Semenov Hydrothermal Field）采集的完整沉积物岩芯及拆分后的归档岩芯半段，于英国海洋沉积物岩芯研究设施（British Ocean Sediment Core Research Facility, BOSCORF）内，通过Geotek ScoutXcan X射线成像系统完成成像扫描。借助该系统的线性与旋转式二维成像功能，所获取的二维多角度X射线放射影像可清晰呈现沉积构造与不同岩性单元间的密度差异，从而实现更细致的岩芯描述。本数据集为英国自然环境研究委员会（NERC）超镁铁质岩赋存矿产资源评估（Ultramafic-hosted mineral Resource Assessment, ULTRA）项目资助的博士研究项目的一部分，项目资助编号为NE/S004068/1；目前所有沉积物岩芯均保存于BOSCORF中以实现长期留存。
