The primary objective of this project is to elucidate the interaction between secondary circulation and cross channel variations in mixing in a stratified channel, and the role that this interaction plays in driving estuarine dispersion. During year one of this three-year project a pilot study was completed which entailed a dye tracer experiment within the Hudson River estuarine regime. The pilot study enabled us to assess our methodology and gain experience for the main experiement conducted in May 2002.

The May 2002 study featured 4 dye experiments that bracketed the neap/spring cycle. The first two experiments occurred during neap tides when tidally mean surface to bottom salinity stratification approached 15 psu. The third injection occurred during the neap to spring transition. The final injection occurred at spring tide and stratification was weak but slowly increasing. All experiemtns commenced wityh an injection of fluorescence dye into the bottom layer and tracked with two boats.
