Physical Oceanography of the Amazon Frontal Zone

AMASSEDS(亚马逊大陆架沉积物研究)是一项大型合作项目，旨在研究亚马逊河在邻近大陆架上的淡水排放。地质学家和化学家将与物理海洋学家合作，研究与沉积物和溶解化学物质的运输有关的过程。这一部分的重点将放在锋区的水结构、环流、内部混合和底部边界层过程上，那里形成了盐度、密度和悬浮泥沙的强烈梯度。将使用船上水文和海流测量、系泊海流阵列、卫星跟踪漂移器和卫星AVHRR(高级甚高分辨率辐射计)数据。

AMASSEDS (AMAzon Shelf SEDiment Study) is a large collaborative effort to study the freshwater discharge of the Amazon River over the adjacent continental shelf. Both geologists and chemists will work together with physical oceanographers to address processes involved in the transport of sediment and dissolved chemical species. The focus of this component will be on the water structure, circulation, internal mixing, and bottom boundary-layer processes in the frontal zone where strong gradients of salinity, density and suspended sediment form. Shipboard hydrography and current measurements, a moored current array, satellite-tracked drifters, and satellite AVHRR (Advanced Very High Resolution Radiometer) data will be used.
