In this project, the PI's will to continue the study of physical processes on the Amazon shelf as part of A Multidisciplinary Amazon Shelf SEDiment Study (AMASSEDS). Moored, shipboard, drifter, and satellite data have been collected over a period of two years to investigate the geological, chemical, and physical processes that control the distributions and fluxes of fresh water, salt, and sediment across the Amazon shelf. Specific focus is on tides, frontal dynamics, wind-driven motions, and the influence of the North Brazil Current on the currents, hydro- graphy, and suspended sediment distributions on the shelf. Collaborative efforts address the role of physical processes in controlling the distributions and fluxes of sediments and chemicals in the water column, and across the sediment-water interface.

在这个项目中，PI将继续研究亚马逊大陆架的物理过程，作为多学科亚马逊大陆架沉积物研究（AMASSEDS）的一部分。在两年的时间里，研究人员收集了系泊、船载、漂流和卫星数据，以调查控制亚马逊大陆架上淡水、盐和沉积物分布和通量的地质、化学和物理过程。具体的重点是潮汐、锋面动力学、风驱动运动，以及北巴西洋流对海流、水文和大陆架上悬浮沉积物分布的影响。协作努力解决物理过程在控制水柱和沉积物-水界面中沉积物和化学物质的分布和通量方面的作用。
