River Watch

Rocky Geyer (left) and postdoctoral scholar Dave Ralston (now a WHOI assistant scientist) remove instruments from a mooring on the working deck of the research vessel Tioga in July 2005. The mooring was deployed for two months in the Merrimack River, near the border of New Hampshire and Massachusetts, to measure temperature and conductivity (a proxy for salinity) and examine how the stratification, or layering, of the water changes with tidal cycles.
