    Metadata Updated: October 27, 2025

    At continuous monitoring sites throughout Maryland, water quality is monitored at shallow water sites located in Chesapeake Bay, Chesapeake Bay tributaries and Maryland Coastal Bay tributaries. YSI (6600 V2 or EXO2) data loggers sample seven environmental parameters: water temperature, specific conductance, dissolved oxygen concentration, oxygen percent saturation, pH, turbidity and fluorescence. Water depth is measured at stations where loggers were deployed at fixed depths. Salinity and chlorophyll are derived from specific conductance and fluorescence, respectively. Each parameter is generally sampled at 15-minute intervals. Most continuous monitoring sites are deployed during the SAV growing season (April-October) with a few sites deployed year-round.
