Fratantoni0095261Ninety-seven years of hydrographic data from two large data sets will be used to study the continuity, response to topography, and seasonal and interannual variability of the shelf break system (jet and front) from the Denmark Strait to the Middle Atlantic Bight. Since the flow is primarily geostrophic, the dominant transport signal will be captured by the temperature and salinity data without need to focus on the rarer direct current measurements from the system. Outliers will be removed through an iterative procedure. Data will be binned in space-time for analysis. Where repeat sections occur, these will be analyzed using standard techniques.

Fratantoni 0095261将使用两个大型数据集的97年水文数据来研究从丹麦海峡到中大西洋湾的陆架断裂系统（急流和锋面）的连续性、对地形的响应以及季节和年际变化。 由于流动主要是地转的，占主导地位的运输信号将被捕获的温度和盐度数据，而不需要集中在罕见的直流测量系统。 将通过迭代程序删除离群值。 数据将在空间-时间中进行分组以进行分析。 如果出现重复切片，将使用标准技术进行分析。
