STOWING FOR THE TRIP—From left, Dave Ralston, Rocky Geyer, and Jim Lerczak stow recovered buoys near Tioga’s bow. The instrument protruding from the bottom of the buoy measured near-surface conductivity and temperature every five minutes for about two months. Conductivity and temperature are used to derive salinity. Salinity readings from both the surface and riverbed are used to derive changes in stratification throughout the tidal cycle. In the study, stirring and mixing of salt and fresh waters is measured along three axes—vertically, across the width of the river, and along its length. This data lays the foundation for quantifying dispersion properties of the estuary.
