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.

提出了一系列的染料研究和相关的水文和水流测量。 染料将被释放在底层的哈德逊河口和跟踪，以量化的diapycnal运输过程，二次环流，和水平运输在分层河口。 特别感兴趣的是二次环流的贡献，垂直和水平交换和最终的影响，沿河口的动量平衡和分散率。 该计划的实地研究和分析阶段将通过数值研究来补充。 这些努力将测试有关失败的经典理论的河口环流来解释观测的假设。
