Virginia Estuarine & Coastal Observing System

Water quality monitoringThe Virginia Estuarine and Coastal Observing System (VECOS) is a website designed to distribute the results of water quality and meteorological data monitoring efforts from the Chesapeake Bay and associated tributaries within Virginia. These data are provided from a variety of monitoring programs conducted by the Chesapeake Bay National Estuarine Research Reserve - Viginia, including high resolution mapping of surface water quality (DATAFLOW), high-frequency measurements of water quality taken every 15 minutes from fixed, shallow water monitoring stations (CONMON), continuous measurements taken from deeper waters along multiple depths (Profiler). VECOS also provides links to external monitoring programs, including high-frequency water quality and meteorological monitoring at deep water locations in the Chesapeake Bay as part of the Chesapeake Bay Interpretive Buoy System (CBIBS), meteorological monitoring locations specific to the York River watershed, and long-term routine water quality sampling, typically taken 12-20 times per year since 1985 through the Chesapeake Bay Program (Longterm).

New Stations added to VECOS monitoring network




Four new continuous monitoring (CONMON) stations, including Salt Ponds, Little Creek, Broad Bay and Linkhorn Bay, are now available on the Virginia Estuarine and Coastal Observing System (VECOS), which is administered and managed by CBNERR. We will monitor water quality conditions at these sites for 3 years (2019-2021). VECOS leverages the expertise of CBNERR field and lab personnel to distribute quality assured data products alongside simple, quick data visualizations associated with these stations. Enhanced with telemetry, these stations also provide realtime data access, bringing the total number of VIMS-supported and/or VIMS-maintained realtime water quality stations supported by VECOS to 15, including 11 Realtime Continuous Monitoring (Realtime CONMON) stations, and 4 Chesapeake Bay Interpretive Buoy System (CBIBS) stations.
