Generally deployed from April - October to measure water quality parameters every 15 minutes with a YSI probe measuring dissolved oxygen, turbidity, chlorophyll, water temperature, salinity, and pH. Currently used by MDDNR, VADEQ, USGS, St. Mary's College, and GMU (Tidal Occoquan River, Belmont Bay)
