This project will examine the spatial and temporal record of terrigenous material in sediments of the deep Atlantic Ocean. Grainsize and geochemical analyses of particles will be analyzed in surface sediments throughout the ocean, in order to distinguish sources (geochemistry) and transport mode (grainsize). Similar analyses will be conducted in a core off West Africa to determine temporal variability of eolian deposition (hence wind strength and continental aridity) from the Sahel and Sahara over the last glacial/ interglacial cycle. The project will be performed by undergraduate students, providing a research experience opportunity at an undergraduate department.

该项目将检查深大西洋沉积物中陆源物质的空间和时间记录。 将在整个海洋的表面沉积物中分析颗粒的晶体化和地球化学分析，以区分来源（地球化学）和运输模式（晶体化）。 在西非的核心中将进行类似的分析，以确定在最后一个冰川/冰川间周期中，萨赫勒和萨哈拉的Eolian沉积（因此风强度和大陆干燥）的时间变化。 该项目将由本科生进行，并在本科生提供研究经验机会。
