Color Reflectance (Spectrophotometer) of IODP Hole 386-M0082B

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）中上述指定钻孔的颜色反射光谱光度学与色度学数据。该数据采集自386航次的陆上作业阶段，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）科考船。岩心剖面经纵向劈开后，每一份存档半岩心均通过三传感器岩心测井仪（Tri-Sensor Core Logger, TSCL；NS Design）进行扫描，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。所得数据采用L*a*b*色坐标系统表示，其中L*为总反射率（明度）指数，取值范围为0%~100%；a*为以0为中性基准的红绿色度分量，b*为以0为中性基准的黄蓝色度分量。研究人员通过MATLAB内置函数lab2rgb将所得L*a*b*色彩值转换为RGB色彩值。如需获取更多方法学相关信息，请参阅Strasser M.等人2023年发表的研究章节，DOI：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）完成提交与校对工作。
