Abstract Using visible light reflectance spectra, ocean sediment cores can be analyzed rapidly for semi-quantitative determination of sediment composition. At present, four minerals (goethite, hematite, chlorite and smectite) and organic carbon contents have been derived from the spectra, and the present study will seek to expand the data processing techniques. Using these refined techniques, cores from the tropical Atlantic will be analyzed to see the relative influence of glacial climate on the Amazon Basin and on the extent and velocity of winds off the Sahara.

摘要 利用可见光反射光谱，海洋沉积物岩心可以 快速分析，用于半定量测定沉积物 混合物. 目前，四种矿物（针铁矿，赤铁矿， 蒙脱石和蒙脱石）和有机碳含量， 来自光谱，本研究将寻求扩大 数据处理技术。 使用这些精细的技术， 来自热带大西洋的岩心将被分析， 冰川气候对亚马逊河流域和 撒哈拉沙漠的风速和范围
