9416074 Houghton The objective of this study is to investigate the flow of the bottom boundary layer (BBL) in the vicinity of the shelfbreak front in the Middle Atlantic Bight using a novel technique (a dye as a Lagrangian follower) in order to resolve the small scale flow near the moving frontal boundary. One of the goals of the study is unambiguously confirm the existence of a mean Lagrangian flow offshore of the BBL and its convergence at the frontal boundary. These results will be importnat ina dvancing our understanding of the dynamics controlling exchange of shelf and slope water at the continental margin and the circulation responsible for enhanced biological productivity at the shelfbreak.

9416074 Houghton 这项研究的目的是使用一种新技术（染料作为拉格朗日随动件）来研究中大西洋湾陆架折断前沿附近的底部边界层 (BBL) 的流动，以解决小问题移动锋面边界附近的尺度流。该研究的目标之一是明确证实 BBL 近海平均拉格朗日流的存在及其在锋面边界的汇聚。这些结果对于增进我们对控制大陆边缘陆架和斜坡水交换的动态以及负责增强陆架断裂处生物生产力的循环的理解具有重要意义。
