Collaborative Research: Deep Basin Experiment Synthesis

作为世界大洋环流实验的一部分，需要资金完成对深海盆地实验的分析和综合。这些数据包括阻流点和断裂区的海流计系泊、中性浮标以及带有示踪剂和营养物的水文数据。建议结合数据分析、反演方法以及准解析和数值模型的层次结构，对巴西盆地内的深部环流产生动态一致的理解。新发现的深部环流特征将纳入分析。这包括深部环流的显著纬向带状，盆地内明显的低频(2级)晃动，大尺度环流中嵌入的大量小涡旋，以及从边界向盆地内部延伸的异常水柱。

Funds are requested to complete the analysis and synthesis of the Deep Basin Experiment conducted as part of the World Ocean Circulation Experiment (WOCE). The data include current meter mooring at choke point and fracture zone, neutrally buoyant floats and hydrographic data with tracers and nutrients. It is propose to use a combination of data analysis, inverse methods, and a hierarchy of quasi-analytic and numerical models to produce a dynamically consistent understanding of the deep circulation within the Brazil Basin. Newly discovered features of the deep circulation will be incorporated in the analysis. These include a prominent zonal banding of the deep circulation, an apparent low frequency (order 2 year) sloshing within the basin, numerous small vortices embedded in the larger scale circulation, and plumes of anomalous water extending away from the boundary into the basin interior.
