Core close-up images of IODP Hole 386-M0089B

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.For further methodological information see methods chapter in Strasser, M. et al., 2023 https://doi.org/10.14379/iodp.proc.386.102.2023

本数据集为国际大洋发现计划（International Ocean Discovery Program, IODP）第386次科考航次（日本海沟古地震学研究）指定钻孔的拆分岩心特写图像集合。本航次的海上作业阶段于2021年4月13日至2021年6月1日期间开展，搭载日本海洋调查船“海明号”（R/V Kaimei），往返于日本横须贺港。本次图像采集工作于航次的陆上作业阶段完成，该阶段于2022年2月14日至2022年3月15日期间在钻探船D/V Chikyu（地球号）上开展。这些特写照片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。成像区间的选取由负责该岩心描述的人员决定。国际大洋发现计划的标准命名规范遵循以下语法格式：航次编号-钻孔编号-岩心编号+岩心类型（其中“H”代表搭载液压活塞取心器（hydraulic piston corer）所获取的GPC岩心，“P”代表搭载推式取心器（push corer）所获取的触发式取心器岩心，详细信息请参见岩心汇总文档）-岩心段编号、段内成像区间顶部深度（单位：厘米）-段内成像区间底部深度（单位：厘米）。例如，"386-M0081A-1P-1,10-30"表示拍摄于第386次航次M0081A号钻孔1P号岩心第1段内10至30厘米区间的照片。如需了解更多方法学细节，请参阅Strasser M.等人2023年发表的相关章节，链接：https://doi.org/10.14379/iodp.proc.386.102.2023
