IODP Expedition 349 Color reflectance

Color reflectance data were measured on section halves using an integration sphere and a UV-VIS spectrophotometer mounted on the Section Half Multisensor Logger (SHMSL). Spectral counts are recorded in the range of 380 to 700 nm, covering the visible spectrum, and binned in ~2 nm bins. Spectral data are reduced from spectra and recorded in tristimulus XYZ values, CieLAB L*a*b* values, and other units.采用安装于半切片多传感器记录仪（Section Half Multisensor Logger, SHMSL）上的积分球与紫外-可见分光光度计，对半切片样本进行颜色反射率数据测量。光谱计数的采集范围覆盖380至700纳米的可见光光谱波段，并以约2纳米为间隔进行分箱存储。经从原始光谱中约简得到的光谱数据，将以三刺激值XYZ、CIELAB L*a*b*色彩空间值及其他单位格式进行记录。
