Overview
The YSI ProQuatro, along with its Quatro cable, allows the use of 4-ports to measure temperature/conductivity, DO, and any two ISEs among pH, ORP, ammonium, chloride, or nitrate creating an extremely powerful handheld multiparameter instrument. Sensors are not included in meter purchases.
Versatile
Connect any Professional Series cable and probe option to the instrument and use the convenient cable management kit to keep everything simple and organized. Cable options range from 1-, 4-, 10-, 20-, and 30-meter choices (up to 100-meters on DO-only cables). Use lab or field probes and switch between the two quickly. The ProQuatro makes an ideal lab BOD instrument with the proven self-stirring BOD probe (EPA Approved). A complete family of accessories also increases the versatility of the YSI ProQuatro. Choose among accessories including carrying cases, flow cells, cable weight, belt clip, and tripod.

After 10 Years, Great Lakes Monitoring Program Still Adapting
The public knows much more about Great Lakes coastal wetlands than it did ten years ago. In those ten years, the information gathered through the Great Lakes Coastal Wetlands Monitoring Program has led to and supported dozens of advances in Great Lakes science while helping nail down the shifting nature of ecosystem health for a vital part of the Great Lakes system. “I probably get one or two requests for information a week,” Don Uzarski, director of the program, told Environmental Monitor. The program’s most recent semi-annual report lists 40 scientific publications using the collected data. In addition, the data has been used in even more restoration projects, graduate theses and presentations.

Cal Poly, San Luis Obispo Manages Monitoring Efforts in Morro Bay
California Polytechnic State University, San Luis Obispo (Cal Poly, SLO), has been monitoring Morro Bay for decades, and while the monitoring program has changed over the years, the dedication to monitoring the bay has remained the same. The project started in 2006 as a Packard Foundation-funded initiative to monitor water quality flowing in and out of Morro Bay. The goal at the time was to use the data collected to develop and inform an ecosystem-based management plan in collaboration with the Morro Bay National Estuary Program (MBNEP). Since the estuary was the focus at the time, researchers were monitoring water flowing into the estuary from Chorro Creek and Los Osos Creek.

Green Water in Green Bay: Using Data Buoys to Monitor the Southern Bay
While the bay of Green Bay has been referred to as the largest freshwater “estuary” in the world, the watershed hosts intensive agriculture and contributes one-third of Lake Michigan’s total phosphorus load. The Fox River flows into the bay, carrying excess nutrients largely the result of non-point source runoff from the watershed. With a history of deterioration extending well into the last century, the bay ecosystem suffered significant declines in water quality. This, in turn, stimulated major clean-up and ongoing restoration efforts to improve water quality. Tracking these changes is an important aspect of ecosystem management.
