Core close-up images of IODP Hole 386-M0085A

Collection of split cores' close-up images from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). The offshore phase of this expedition took place between 2021-04-13 and 2021-06-01 onboard Japanese R/V Kaimei from and to Yokosuka, Japan. Images were obtained during the onshore phase of the expedition, which took place between 2022-02-14 – 2022-03-15 onboard D/V Chikyu. Close-up photos were taken utilizing a standard photo camera by sedimentologists during visual core description. Decision on imaged intervals was subject to the core describers in charge. The standard IODP convention for labelling follows the syntax expedition number – hole – core plus core type (\"H\" [for hydraulic piston corer] indicates GPC cores, and \"P\" [for push corer] indicates trigger corer cores, see core summaries for further information) – section, top of interval in section [in cm] – bottom of interval in section [in cm], for instance \"386-M0081A-1P-1,10-30\" identifies a photo taken from the interval 10-30 cm within section 1 of core 1P from hole M0081A of expedition 386.

本数据集为国际大洋发现计划（International Ocean Discovery Program, IODP）386航次（日本海沟古地震学研究）指定钻孔的劈开岩心近景图像集合。该航次的海上作业阶段于2021年4月13日至2021年6月1日期间在日本科考船“开南号”（R/V Kaimei）上开展，往返航次始于并终于日本横须贺港。本数据集的图像采集于该航次的陆上作业阶段，该阶段于2022年2月14日至2022年3月15日期间在“地球号”深海钻探船（D/V Chikyu）上进行。所有近景照片均由沉积学家在岩心目视描述过程中，使用标准数码相机拍摄完成。成像段的选取由负责的岩心描述人员自主决定。国际大洋发现计划的标准命名规则遵循以下语法：航次编号-钻孔编号-岩心编号+岩心类型（"H"代表液压活塞取心器（hydraulic piston corer, HPC）对应的GPC岩心，"P"代表推进式取心器对应的触发式取心器岩心，详细信息参见岩心汇总文档）-岩心段-段内顶界深度（单位：cm）-段内底界深度（单位：cm）。示例："386-M0081A-1P-1,10-30"指拍摄自386航次M0081A钻孔1P岩心第1段内10~30 cm区间的图像。[…]
