Forrest Career and Technology Center: Our Students' Answer to Low-Cost Water Quality Monitoring in the Chesapeake Bay
Bay Observation Boxes are low-cost, automated water quality monitors that collect and send measurements to the Internet every 15 minutes for:
Temperature
Dissolved Oxygen
pH
Salinity
Electrical Conductivity
We build our BOBs for about $900 each using makerspace technology. Comparable retail products sell for upwards of $20,000.
We hope to expand water quality monitoring in the Chesapeake Bay to include the microecosystems of many more small creeks and coves.
Currently, we are analyzing our data to evaluate the accuracy of our sensors and improve them.
The data have the potential to signal the health of the Bay during a changing climate, allowing scientists to respond appropriately.
We are especially interested in the impact of water quality on oysters, as this keystone species is crucial for a thriving ecosystem.
Oysters in the Bay:
Die in the "dead zones" of low oxygen that often develop in the summer
Develop fewer and thinner shells in more acidic water
We are working with the St. Mary's River Watershed Association on a related project to build and deploy BOBs at its existing and potential oyster restoration reefs.
To enable student scientists to practice real-world problem-solving, engineering, monitoring, and data analysis
To increase public awareness of importance of water quality, especially during a time of changing climate
To support oyster reef restoration as these mollusks are keystone species in the health of the Chesapeake Bay
With St. Mary's River Watershed Association, we have about 14 BOB locations in Southern Maryland, with eight in Breton Bay, two in the Patuxent River, and five in St. Mary's river. We are working at:
Calvert Marine Museum in Solomon's Island
Leonardtown Wharf
The Friends of St. Clement's Bay oyster sanctuary at Lover's Point
Chesapeake Biological Laboratory (occasional placement for testing)
The St. Mary's College of Maryland dock
Breton Bay Estates community pier
Private docks south of Lover's Point, north of Foxes Point, south of Paw Paw Point, and in Canoe Neck Creek
Five existing and potential oyster restoration reefs in the St. Mary's River
This work has been made possible by three Environmental Education grants from The Chesapeake Bay Trust to the Dr. James A. Forrest Career and Technology Center. The project was conceived of and is largely driven by the volunteer efforts of Norman and Shelly O'Foran, in partnership with Natural Resources Teacher Dorothy Birch and her students. We collaborate with other classes, such as Nathan Swick's Engineering and Casey Page's Graphic Communications.
We also work with St. Mary's River Watershed Association, which has related grants to build and deploy eight BOBs at its existing and potential oyster restoration sites. We share data, lessons learned, upgrades, and other resources.
