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.

提出了一系列染料研究以及相关的水文和电流测量。 染料将在哈德逊河河口的底层中释放，并进行跟踪，以量化分层河口的二比传输过程，次级循环和水平运输。 特别感兴趣的将是二级流通对垂直和水平交换的贡献及其对及及及及时的势头平衡和分散率的最终影响。 该程序的现场研究和分析阶段将由数值研究补充。 这些努力将检验有关河口循环古典理论解释观察结果的假设。
