Color Reflectance (Spectrophotometer) of IODP Hole 386-M0095B

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).本数据集包含国际大洋发现计划（International Ocean Discovery Program, IODP）386航次（日本海沟古地震研究）指定钻孔的颜色反射光谱光度法与比色法数据。该数据采集于386航次的陆上作业阶段，航次作业时间为2022年2月14日至2022年3月15日，作业平台为“地球号”（D/V Chikyu）深海钻探船。岩心样品经纵向劈开后，每一块归档半岩心均采用三传感器岩心测井仪（Tri-Sensor Core Logger, TSCL; NS Design）进行扫描，该设备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。所得数据采用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*对应绿色色度（以0为中性值），b*对应蓝色色度（以0为中性值）。研究人员通过MATLAB内置程序lab2rgb将L*a*b*值转换为RGB色彩值。如需了解更多方法学细节，请参阅Strasser M.等人2023年发表的研究论文：https://doi.org/10.14379/iodp.proc.386.102.2023。 本数据集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团队（https://www.ecord.org）提交并完成校对。
