Development of a Reference Base for Eolian Sedimentary Studies in the Pacific and to Apply it to Studies of Quaternary Eolian Sedimentation in the Equatorial Pacific

大气成分的化学和矿物学 海洋沉积物可以用来追踪 灰尘 从这些数据中，可以跟踪 在过去的某个时候，空气质量和风的轨迹。 这 建议要求支持建立一个正式的数据库， 表面沉积物矿物学、气溶胶矿物学和空气质量 太平洋的轨道。 这些数据可用于 重建过去的风和气团运动， 精度 这项研究很重要，因为重建过去的 风向和强度提供了重要的信息 大气层对过去气候变化的反应 过去 风的强度和方向也有助于测试灵敏度 由于风向和强度 是这些数值模拟的主要输出。

The chemistry and mineralogy of air-borne components of marine sediments can be used to trace the source location of the dust. From these data it is possible then to trace the trajectory of air masses and winds at times in the past. This proposal requests support to develop a formal data base of surface sediment mineralogy, aerosol mineralogy, and air mass trajectory for the Pacific Ocean. These data can then be used to reconstruct past winds and air mass movements with greater accuracy. The research is important because the reconstruction of past wind directions and intensities provides important information about how the atmosphere responded to past climate change. Past wind intensities and directions also help to test the sensitivity of General Circulation Models, since wind direction and intensity are principal output from these numerical simulations.
