Physical properties (MSCL) of IODP Hole 386-M0083C

Multi-Sensor Core Logger (MSCL) data (P-wave velocity, gamma ray attenuation (GRA) density, magnetic susceptibility, natural gamma radiation (NGR), noncontact resistivity (NCR)) from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). These data were obtained from whole round core sections by means of a Geotek MSCL during the offshore phase of the expedition. The offshore phase of expedition 386 took place between 2021-04-13 and 2021-06-01 onboard Japanese R/V Kaimei from and to Yokosuka, Japan. As the aforementioned parameters are sensitive to temperature core sections were stored for at least 6 hours after arrival on deck before measurement to allow for temperature equilibration. The core physical properties were measured at predetermined optimal instrument-based spatial and temporal sampling intervals. GRA density, P-wave velocity, NCR, and magnetic susceptibility were measured every 2 cm, and NGR measurements were obtained every 10 cm.

国际大洋发现计划（IODP）第386航次（日本海沟古地震学）上述钻孔的多传感器岩心记录仪（MSCL）数据，包括纵波速度（P-wave velocity）、伽马射线衰减（GRA）密度、磁化率、自然伽马辐射（NGR）和非接触电阻率（NCR）。这些数据是在航次海上阶段通过Geotek MSCL从全岩心段获取的。第386航次的海上阶段于2021年4月13日至2021年6月1日在日本R/V Kaimei号上进行，往返于日本横须贺。由于上述参数对温度敏感，岩心段在运抵甲板后、测量前需存放至少6小时以达到温度平衡。岩心物理性质的测量采用预先设定的、基于仪器的最优时空采样间隔：GRA密度、纵波速度、NCR和磁化率的测量间隔为2厘米，NGR的测量间隔为10厘米。更多方法学信息详见Strasser, M.等2023年发表的方法章节，DOI：https://doi.org/10.14379/iodp.proc.386.102.2023
