Note: All optical DO membranes are now manufactured from anti-fouling copper alloy; these membranes directly replace black plastic membranes. Anti-fouling membranes can be used on existing ROX probes with no detrimental effects on data. The copper-alloy YSI 6155 optical DO membrane may arrive with surface patina and/or discoloration. This will not affect membrane performance.
- (1) YSI 6155 optical DO membrane
- (3) Installation screws
- (1) Hex wrench
- (1) Instruction sheet with calibration coefficients
The 6155 kit comes with everything required for installation. To replace the membrane, remove the old membrane and clean around the probe face. Make sure the surface under the membrane is clean and dry before replacing. After replacing the new membrane, power the sonde and enter the calibration constants (K numbers included with the membrane kit).

Wisconsin watershed program involves high schools to collect, share data
A group of high schoolers in the Green Bay, Wisc. area are learning about careers in environmental science thanks to the Lower Fox River Watershed Monitoring Program. The program, supported by the University of Wisconsin, has involved more than 700 students since its 2003 launch. “We have almost ten years of data,” said Annette Pelegrin, program coordinator. “It began in 2003 with five watersheds. We’ve trained teachers and schools that are interested and showed them how to measure different parameters.” Those include flow, temperature, transparency and turbidity of the program’s streams. YSI 55 meters are used to measure dissolved oxygen and levels of phosphorus, ammonia and nitrogen are checked with a Hach colorimeter.

Environmental Dredging and Remedial Construction
Though dredging is often painted in a negative light, dredging initiatives and projects are often conducted to improve environments, begin recovery periods for water beds contaminated with toxins, and reinvigorate ecological systems and habitats. Many of the technicians and engineers who plan and execute dredging projects are dedicated to balancing the economic benefits of dredging with protecting the environment. Sevenson Environmental Services Inc. provides sediment remediation as one of many key services offered to help restore natural environments. Steven Shaw spent more than a decade working as an engineer on various dredging projects before finding his way to Sevenson eight years ago.

Caring for the Chesapeake: Supporting the Iconic Bay Starts with Good Monitoring Data
The Chesapeake Bay is enormous: the Bay and its tidal tributaries have 11,684 miles of shoreline—more than the entire U.S. west coast. It is the largest of more than 100 estuaries in the United States and the third largest in the world. The Bay itself is about 200 miles long, stretching from Havre de Grace, Maryland, to Virginia Beach, Virginia. But the Chesapeake Bay isn’t just enormous--it’s enormously important. The Chesapeake Bay Program reports that its watershed covers about 64,000 square miles and is home to more than 18 million people, 10 million of which live along or near the Bay’s shores.
