Narragansett Bay Water Quality Monitoring Network

Bay fixed-site monitoring data are provided by the cooperative efforts of the RI Department of Environmental Management Water Resources Division, the Narragansett Bay National Estuarine Research Reserve, the Narragansett Bay Commission, the URI Graduate School of Oceanography, Roger Williams University, and the Bay Window Program.

Buoys were equipped with two sondes that measured temperature, salinity, dissolved oxygen and depth at approximately 1 meter from the bottom and 0.5 meters below the surface. In addition, chlorophyll fluorescence was measured by the near surface sonde. Measurements were collected at fifteen minute intervals and transmitted to shore via cellular modems every eight hours or via radio signal every fifteen minutes. The instruments were serviced every two weeks to minimize biofouling.

Additional Data Sources and Information:

  • URI-GSO data from Professor Dana Kester
  • Narragansett Bay Commission EMPACT project
  • Narragansett Bay NERR Historical Data
