Hudson River Monthly CTD Surveys

A monitoring program was initiated in 2001 to monitor the Hudson River's basic state variables of salinity, temperature and density along transects from New York Harbor to Troy. John Lipscomb of the Hudson Riverkeeper has worked with us to keep this "tradition" alive, and now the database provides an unusually comprehensive summary of these variables under a wide range of tidal and riverflow forcing.
