Core close-up images of IODP Hole 389-M0099F@en

Collection of split cores' close-up images from the above given hole of International Ocean Discovery Program (IODP) Expedition 389 (Hawaiian Drowned Reefs). The offshore phase of this expedition took place between 2023-08-31 and 2023-10-31 onboard multipurpose vessel MMA Valour sailing from and to Barbers Point Harbor, Hawai'i, USA, followed by the onshore phase from 2025-02-06 to 2025-02-26 at the Bremen Core Repository (BCR) hosted at MARUM – Center for Marine Environmental Sciences, University of Bremen. Close-up photos were taken utilizing a standard photo camera by sedimentologists during visual core description of the archive half. Decision on imaged intervals was subject to the core describers in charge. The standard IODP convention for labelling follows the syntax Exp-SiteHole-CoreCoretype-Section_ImageName_IntervalTop [in cm in section]-IntervalBottom [in cm in section]. For example, a file 389-M0096A-02R-2_Picritic-Basalt_1-18.jpg identifies a close-up image of picritic Basalt from section 2 interval 1 – 18 cm of core 2R (R indicating rotary coring method), from Hole M0096A from Expedition 389. […]本数据集为国际大洋发现计划（International Ocean Discovery Program, IODP）389次航次（夏威夷淹没礁课题）指定钻孔的岩心拆分半段特写图像集合。本次航次的海上作业阶段于2023年8月31日至2023年10月31日期间开展，搭载多用途船舶“MMA Valour”号，往返于美国夏威夷巴伯斯角港；陆上作业阶段则于2025年2月6日至2025年2月26日，在不来梅大学海洋环境科学中心（MARUM – Center for Marine Environmental Sciences）下属的不来梅岩心库（Bremen Core Repository, BCR）进行。这些特写照片由沉积学家在对存档半岩心开展目视岩心描述期间，使用标准摄影相机拍摄完成，成像区间的选定由负责该岩心描述的人员自主确定。国际大洋发现计划的标准命名规范遵循如下语法格式：航次号-站位钻孔号-岩心号-岩心类型_图像名称_（岩心段内）层位顶部（单位：厘米）-（岩心段内）层位底部（单位：厘米）。例如，文件名为389-M0096A-02R-2_Picritic-Basalt_1-18.jpg的图像，对应389次航次M0096A钻孔的2R号岩心（其中R代表回转取心方式）中2号岩心段1至18厘米层位的苦橄玄武岩特写图像。[…]
