Visual core description of IODP Hole 389-M0106A@en

Collection of visual core description (VCD) sheets (hand drawn originals) and digital lithostratigraphic logs from the above given hole of International Ocean Discovery Program (IODP) Expedition 389 (Hawaiian Drowned Reefs). VCD was performed on unsampled archive halves of split core sections directly after line scan imaging, during the onshore phase of expedition 389, which took place between 2025-02-06 to 2025-02-26 at the Bremen Core Repository (BCR) hosted at MARUM – Center for Marine Environmental Sciences, University of Bremen. The lithology of each core section is represented on the hand drawn VCDs by graphic patterns next to the line scan image of the archive-half core section. Further, a wide variety of features that characterize the sediment are indicated in additional columns. The information from the hand-drawn VCD sheets was then transferred into the mobile Drilling Information System database, from where it could be accessed semi-automated to produce digital lithologic columns using Strater 5 software (by Golden Software). The dataset is accompanied by a composite plot of core images acquired by optical line scanning. For the original images see corresponding data set 'Line scan images of IODP Hole 389-M00##'. […]本数据集包含国际大洋发现计划（International Ocean Discovery Program, IODP）389航次（夏威夷淹没礁航次）对应钻孔的岩芯目视描述（visual core description, VCD）手绘原稿，以及数字化岩石地层测井曲线。VCD工作于该航次的陆上阶段开展，该阶段于2025年2月6日至2025年2月26日在设于不来梅大学海洋环境科学中心（MARUM——不来梅大学海洋环境科学中心）的不来梅岩芯库（Bremen Core Repository, BCR）进行，具体操作为在劈分岩芯的未采样存档半段完成线扫描成像后即刻开展目视描述工作。每份劈分岩芯存档半段的线扫描图像旁，以图形图案标注对应岩芯段的岩性，该信息呈现于手绘VCD图中；此外，额外列项还标注了多种用以表征沉积物特征的地质细节。随后，手绘VCD图册中的全部信息被录入移动钻井信息系统（Drilling Information System）数据库，可通过该数据库半自动化调取数据，并借助金软件公司（Golden Software）开发的Strater 5软件生成数字化岩性柱状图。本数据集附带光学线扫描采集的岩芯图像合成图。原始图像请参阅对应数据集"IODP 389-M00##孔线扫描图像"。[…]
