Color Reflectance (Spectrophotometer) of IODP Hole 386-M0083D

Color reflectance spectrophotometry and colorimetry data from the above given hole of International Ocean Discovery Program (IODP) Expedition 386 (Japan Trench Paleoseismology). The data where obtained during the onshore phase of expedition 386 which took place between 2022-02-14 – 2022-03-15 onboard D/V Chikyu. After longitudinal splitting of the core sections, each archive half was scanned by the Tri-Sensor Core Logger (TSCL; NS Design) including a noncontact imaging spectrophotometer (MetaVue VS3200; X-Rite), recording data at 2-cm sampling interval. The obtained data is represented in the L*a*b* color coordinate system, where L* is a total reflectance index ranging 0%–100%, a* is green (0) chromaticity, and b* is blue (0) chromaticity. L*a*b* values were transferred into RGB values using the MATLAB routine lab2rgb.For further methodological information see methods chapter in Strasser, M. et al., 2023 https://doi.org/10.14379/iodp.proc.386.102.2023 Data was submitted and proofread by Vera Barbara Bender, MARUM - Center for Marine Environmental Sciences (University Bremen) on behalf of ECORD Science Operator Data Management (https://www.ecord.org).本数据集涵盖国际大洋发现计划（International Ocean Discovery Program, IODP）386航次（日本海沟古地震学研究）指定钻孔的颜色反射光谱光度法与色度学数据。数据采集于386航次的陆上阶段，该航次于2022年2月14日至2022年3月15日期间在“地球号”（D/V Chikyu）钻探船上开展。岩心剖面沿纵向劈开后，每一块归档半岩心均通过三传感器岩心测井仪（Tri-Sensor Core Logger, TSCL; NS Design）完成扫描，该仪器搭载非接触式成像分光光度计（MetaVue VS3200; X-Rite），以2厘米的采样间隔记录数据。所获数据采用L*a*b*颜色坐标系表示，其中L*为总反射率指数，取值范围为0%~100%；a*代表以0为基准的红绿色度分量，b*代表以0为基准的黄蓝色度分量。研究人员已通过MATLAB内置的lab2rgb程序将L*a*b*值转换为RGB值。如需进一步了解方法学细节，请参阅Strasser M.等人2023年发表的研究中的方法章节：https://doi.org/10.14379/iodp.proc.386.102.2023 本数据由不来梅大学海洋环境科学中心（MARUM）的Vera Barbara Bender代表ECORD科学运营商数据管理部门（https://www.ecord.org）提交并完成校对。
