Core-section summary for IODP Site 389-M0100@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. […]本数据集收录国际大洋发现计划（International Ocean Discovery Program, IODP）389次航次（夏威夷淹没礁体）海上作业阶段，于指定勘探站位回收的岩心段清单。本次海上作业阶段于2023年8月31日至2023年10月31日期间开展，作业平台为多用途船舶"MMA Valour"，往返航次均以美国夏威夷州巴伯斯角港为起止港。本次岩心采集采用Benthic公司第五代便携式遥控钻探装置（Portable Remotely Operated Drill, PROD5）完成。按照IODP标准规范，从每个岩心管取出的2.75米岩心衬管将根据岩心收获率切割为1或2段，单段最大长度不超过1.5米。本航次389共使用两种岩心衬管：铝合金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。从岩心捕集器中回收的样品将作为独立岩心段，标记为"CC"（即岩心捕集器段），并置于岩心管回收的最后一段岩心段之后。IODP岩心段的标准命名规则包含以下要素：航次编号、钻孔编号、岩心编号、岩心类型及段号。示例：岩心段标签（样本标签列，Sample label）389-M0097A-15R-2 代表第389航次M0097A钻孔的第15号岩心（后缀R表示该岩心采用旋转取心法回收）的第2段。[…]
