The YSI EXO represents the next generation of water quality instruments from YSI. The advanced sonde platform offers a wide range of capabilities to those dedicated to monitoring natural aquatic environments such as oceans, estuaries, rivers, lakes, and groundwater. With a highly efficient power management platform, robust construction, and chemistry-free anti-fouling system, EXO allows accurate data collection for up to 90 days between service intervals.

The EXO3 sonde includes four sensor ports and a central anti-fouling wiper option. Sensor parameters include temperature, conductivity, depth, dissolved oxygen, pH, ORP, total algae (phycocyanin and chlorophyll), turbidity, and fluorescent dissolved organic matter (fDOM). The sonde can also output 4 calculated parameters including salinity, specific conductance, total dissolved solids (TDS) and total suspended solids (TSS).

All EXO sensors are digital sensors with on-board signal processing and memory. Built-in sensor diagnostic and calibration data allows users to calibrate multiple sensors in one sonde and distribute to various other sondes in the field. Wet-mateable connectors allow for swaps in wet conditions, while active port monitoring automatically detects each sensor and verifies operation.

Everglades Restoration: A Story of Wetlands and Water

The Everglades are famous as a popular tourist destination. In 2019, over one million people visited the famous national park that makes up their southern portion. They are also famous, though probably less so, for ongoing, large-scale restoration efforts aiming to restore some of the hydrology that earned the system the nickname the River of Grass. [bctt tweet="Restoring the River of Grass to something closer to its former state will provide timely relief for vital wetlands that support wildlife, industry and the 8 million people that utilize the Everglades for the fresh water they provide.

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.

Fisheries Management Drives Fish Populations Recovery

You might be surprised to hear good news about the world’s oceans. The dominant narrative for years has been that the oceans’ sea life populations are on the brink of collapse. But, according to research Ray Hilborn published in January in the Proceedings of the National Academy of Sciences, the ocean’s fisheries are bouncing back, provided that they’re well managed. “The bottom line is that if fisheries are managed they are sustainable,” Hilborn, a professor at the University of Washington’s school of aquatic and fisheries sciences, told Environmental Monitor. New evidence of recovery After two decades of recovering fish populations, many of the world’s fisheries are stable or recovering, Hilborn’s research shows.
