Core-section summary for IODP Site 389-M0102@en

List of recovered core sections from the above given site of International Ocean Discovery Program (IODP) Expedition 389 (Hawaiian Drowned Reefs) during the offshore phase of this expedition. The offshore phase 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. Cores have been acquired by Benthic's fifth-generation Portable Remotely Operated Drill (PROD5). Following IODP convention, the 2.75 m liners extracted from each core barrel were cut into one or two sections (depending on core recovery) with a maximum section length of 1.5 m. Two types of liner were used during Expedition 389; Aluminum and polycarbonate liners, each requiring different treatment at this initial stage. Material recovered from the core catcher is treated as a separate section labelled \"CC\" for core catcher and placed below the last section recovered from the core barrel. The IODP standard naming of sections includes the following information: expedition number, hole, core, core type and section. For example, a section label (column Sample label) 389-M0097A-15R-2 represents section 2, core 15R (R indicating the core has been recovered by rotary coring method), from Hole M0097A during Expedition 389. […]本数据集收录了国际大洋发现计划（International Ocean Discovery Program, IODP）第389航次（夏威夷淹没礁）海上作业阶段，从指定作业站点回收的岩心分段清单。该海上作业阶段于2023年8月31日至2023年10月31日期间开展，作业船舶为往返于美国夏威夷州巴伯斯角港的多用途船舶"MMA Valour"。本次航次的岩心由本特奇公司第五代便携式遥控钻机（PROD5）采集获取。按照IODP的通用作业规范，从每个岩心筒中取出的2.75米长衬管将根据岩心收获率切割为1至2段，单段最大长度为1.5米。第389航次共使用两类衬管：铝制衬管与聚碳酸酯衬管，二者在初始处理阶段需采用不同的操作流程。从岩心爪中回收的物料将作为独立分段，标注为"CC（岩心爪）"，并置于岩心筒回收的最后一段下方。IODP标准的分段命名规则包含以下信息：航次编号、钻孔编号、岩心编号、岩心类型以及分段编号。例如，样本标签为"389-M0097A-15R-2"的分段，代表第389航次M0097A钻孔中，采用回转取心法（rotary coring method）获取的15号岩心的第2分段。[…]
