Lightness data extracted from core images of sediment core GeoB24009-1@en

Field data: Lightness data extracted from core images of gravity corer sediments collected during project Kerguelen Plateau Sediment Drifts with RV Sonne Cruise SO272 in February and March 2020. Red, Green, Blue, Hue, Saturation, Lightness data were extracted from a 5 cm long and 0.2 mm wide area in the core center using the IGOR PRO software. The gravity cores were retrieved from the Labuan and Gaggatt Basin spanning Plio-Pleistocene to Eocene sediments. Lightness data were extracted to characterise the color of the sediment and document changes.野外实测数据：2020年2月至3月，在凯尔盖朗高原沉积物漂移项目（Kerguelen Plateau Sediment Drifts）框架下，搭载松内号科考船（RV Sonne）执行SO272航次所采集的重力柱沉积物岩芯图像中提取的亮度（Lightness）数据。研究人员借助IGOR PRO软件，从岩芯中心5厘米长、0.2毫米宽的区域内提取了红、绿、蓝、色相、饱和度及亮度数据。本次获取的重力岩芯分布于拉布安盆地与加加特盆地，沉积物时代覆盖上新世-更新世至始新世。本次提取亮度数据的目的在于表征沉积物颜色特征并记录其变化过程。
