Moisture and density (MAD) from IODP Hole 386-M0094A

Moisture and density (MAD) data from discrete samples from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). During the onshore phase of expedition 386, which took place between 2022-02-14 – 2022-03-15 onboard D/V Chikyu, discrete samples for MAD measurements (bulk density, dry density, grain density, water content, porosity, and void ratio) were taken from the work halves using 10 cubic centimetre syringes at an approx. down-core resolution of every 2 meters. Sampling depths were adapted and slightly modified for layers of special interest, such as tephras. Samples were processed and measured directly after sampling onboard Chikyu. For the measurements themselves samples were transferred to glass beakers of known weight and volume.For further methodological information see methods chapter in Strasser, M. et al., 2023 https://doi.org/10.14379/iodp.proc.386.102.2023

国际大洋发现计划（International Ocean Discovery Program, IODP）386航次（日本海沟古地震学研究）对应钻孔的离散样品湿度与密度（Moisture and Density, MAD）数据集。该航次作业阶段于2022年2月14日至2022年3月15日在"Chikyu"号深海钻探船上开展，作业期间使用10立方厘米注射器，以约每2米的岩芯垂向采样间距从岩芯工作半面采集用于MAD测量的离散样品，测量指标包括体积密度、干密度、颗粒密度、含水量、孔隙度与孔隙比。针对火山灰层等特殊关注层位，采样深度可进行调整与适当修正。样品在"Chikyu"号船上采集后即刻进行处理与测量。测量环节中，样品被转移至已知重量与体积的玻璃烧杯中。更多方法学细节详见Strasser M.等人2023年发表的研究（https://doi.org/10.14379/iodp.proc.386.102.2023）中的方法章节。
