Merrimack River—WHOI scientists Rocky Geyer and Jim Lerczak explore the dynamics of estuaries, where rivers tumble into tides, salt water mixes with fresh, and detritus washed from the land churns with material imported from the sea. How will an estuary respond to a sewage or oil spill? A drought or storm? To rising sea level? To answer these questions, the scientists have been studying three dramatically different estuarine settings: the Hudson River in New York and the North River and Merrimack River (aboard R/V Tioga in July) in Massachusetts.
