Great Bay Coast Watch 1990-1999: A Ten Year Report On The Volunteer Water Quality Monitoring Of The Great Bay Estuarine System

The Great Bay Coast Watch (GBCW) was founded in 1990 to help protect the long-term health of New Hampshire's coastal environment through volunteer monitoring and education programs. At sites throughout the Great Bay Estuarine System, GBCW volunteers measure water temperature, pH, salinity, dissolved oxygen, transparency, fecal coliform bacteria, and phytoplankton. This ten-year report describes sampling methods and presents the findings to date. The information contained here may be useful to educators, researchers, resource managers and interested citizens alike.
