The Chesapeake Bay area, located in NOAA’s Northeast Region, provides an excellent opportunity to showcase the benefit of integrating existing sentinel stations and sentinel sites into NOAA’s Sentinel Site Program. The Chesapeake Bay Sentinel Site Cooperative provides integrated observations across a host of environmental monitoring programs within the Bay area. The goal of the cooperative is to provide information to Chesapeake Bay communities and managers who need to address challenges such as storm flooding, long term, local sea level rise, barrier island movement, degraded water quality, and wetland loss. The information will also be useful to federal and state restoration planners and living resource managers who are addressing these challenges.
Monitoring surface elevation, subsidence rates, water quality, vegetation, and living resources at sentinel sites; networking sentinel site data with Bay-wide monitoring stations; sea level rise prediction and planning tools; community education and outreach.
Twenty NOAA tide stations, including 14 National Water Level Observing system gauges with long term sea level trends available
Numerous historic tide gauge datasets and water level observations from other agencies (e.g. U.S. Geological Survey, U.S. Army Corps of Engineers, the Smithsonian Institution, U.S. Fish & Wildlife Service, National Park Service)
Over 30 active Continuously Operating GPS Reference Stations within 20 miles of the coast or coastal estuaries, including one co-located at a National Water Level Observation Network tide station (Solomon’s Island)
Over 50 surface elevation table datasets connected to the National Spatial Reference System for monitoring wetland elevation change (over 200 surface elevation table datasets available through sister agencies, including over one hundred sites within Blackwater National Wildlife Refuge)

Did you know that almost half of seafood production globally comes from aquaculture? Aquaculture is the breeding, rearing, and harvesting of fish, shellfish, plants, algae and other organisms in all types of water environments.
