Core close-up images of IODP Hole 389-M0097B@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）指定钻孔的劈裂岩心特写图像集。该航次的海上作业阶段于2023年8月31日至2023年10月31日实施，搭载多用途科考船“MMA Valour”号，往返于美国夏威夷州巴伯斯角港；后续陆上处理阶段于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）完成。这些特写照片由沉积学家在对归档半岩心开展目视岩心描述期间，使用标准摄影器材拍摄完成；成像岩心段的选取由当班负责的岩心描述人员确定。国际大洋发现计划的标准命名规则遵循以下语法格式：航次号-站位孔位-岩心号-岩心类型_图像名称_段顶距[单位：厘米，以岩心小节计]-段底距[单位：厘米，以岩心小节计]。例如，文件名为389-M0096A-02R-2_Picritic-Basalt_1-18.jpg的图像，对应389航次M0096A钻孔2R号岩心的第2小节，其成像区间为该小节内1至18厘米，岩性为苦橄玄武岩，其中“R”代表回转取心法。[…]
