Collaborative Research: Lagrangian Studies of Mixing and Secondary Circulation in a Stratified Channel

提出了一系列的染料研究以及相关的水文和海流测量。染料将被释放在哈德逊河河口的底层，并被跟踪，以量化分层河口中的双日输送过程、次生环流和水平输送。特别值得关注的是次级环流对垂直和水平交换的贡献，以及它们对河口沿岸动量平衡和弥散率的最终影响。该方案的实地研究和分析阶段将得到数值研究的补充。这些努力将检验有关经典河口环流理论未能解释观测结果的假设。

A series of dye studies and associated hydrographic and current measurements are proposed. Dye will be released in the bottom layer of the Hudson River estuary and tracked in order to quantify diapycnal transport processes, secondary circulations, and horizontal transport in a stratified estuary. Of particular interest will be the contributions of secondary circulations to vertical and horizontal exchange and their ultimate influence on the along-estuary momentum balance and dispersion rates. The field study and analysis phases of the program will be complemented by numerical studies. These efforts will test hypotheses concerning the failure of classical theories of estuarine circulation to explain observations.
