Color Reflectance (Spectrophotometer) of IODP Hole 386-M0085D

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) to red (>0) chromaticity, and b* is blue (<0) to yellow (>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

国际大洋发现计划（International Ocean Discovery Program, IODP）第386航次（日本海沟古地震学）上述钻孔的颜色反射分光光度法及色度学数据。这些数据获取于2022年2月14日至3月15日期间在“地球号”钻探船（D/V Chikyu）上开展的第386航次陆上阶段。岩心段纵向劈分后，每个存档半岩心由三传感器岩心记录仪（Tri-Sensor Core Logger, TSCL；NS Design公司）扫描，该仪器包含一台非接触式成像分光光度计（MetaVue VS3200；X-Rite公司），数据采样间隔为2厘米。获取的数据采用L*a*b*颜色坐标系表示，其中L*为总反射率指数（范围0%–100%），a*表示从绿色（<0）到红色（>0）的色度，b*表示从蓝色（<0）到黄色（>0）的色度。L*a*b*值通过MATLAB函数lab2rgb转换为RGB值。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。
