Overview
The YSI EXO3s represents an advanced sonde platform that 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.
Multi-Port Water Quality Sonde
The EXO3 sonde includes four sensor ports and a central anti-fouling wiper option. Sensor (not included with sonde purchase) parameters include:
- Temperature
- Conductivity
- Depth
- Dissolved oxygen
- pH
- ORP
- Total algae (phycocyanin or phycoerythrin along with chlorophyll)
- Turbidity
- Fluorescent dissolved organic matter (fDOM)
- Rhodamine WT
- UV nitrate
- ISE ammonium
- ISE nitrate
- ISE chloride
Outputs Four Calculated Parameters
- Salinity
- Specific conductance
- Total dissolved solids (TDS)
- Total suspended solids (TSS)
Onboard Signal Processing and Memory
All EXO sensors are digital sensors with onboard signal processing and memory. Built-in sensor diagnostic and calibration data allow users to calibrate multiple sensors in one sonde and distribute them 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.

Water Conservation and Smart Growth in Texas
As states face annual droughts and water use continues to grow in order to meet population and production demands, water conservation is essential to protecting natural resources and long-term reliance. Over the years, conserving water has become more necessary as the world’s natural resources continue to be strained in order to meet needs. As a result, water conservation consultants have filled an essential niche in resource management. Eddie Wilcut, the Water & Energy Efficiency Practice Leader at Plummer , started his career in the Air Force, where he took some classes focusing on water resources. In those classes, Wilcut read Aldo Leopold’s “A Sand County Almanac,” and a specific line has stuck with him for the past 26 years.

It’s a Buoy! Highlighting the New NexSens XB-200 Data Buoy
As scientists seek to better understand aquatic ecosystems, utilizing small data buoys to monitor offshore and cover more water is becoming commonplace. The new NexSens Technology XB-200 data buoy was designed for inland and coastal monitoring applications. Although compact, the platform is designed with adequate space for multiple sensors and measurement electronics. When configured with the NexSens X3 data logger with IoT connectivity, internal batteries, solar panels, select sensors, and other accessories, the new buoy provides an off-the-shelf solution for any monitoring project. The new buoy concept was developed by the NexSens product development team with significant user input.

Predicting and Monitoring Ice Weather Events: The Great Lakes Approach to Ice Research
Ice cover on the Great Lakes provides numerous recreational and economic opportunities, including ice fishing, snowmobile charters, and ice caves on the lakes. Unfortunately, declining ice cover and increasing related weather events due to climate change, as well as other environmental stressors, have put such opportunities at risk. Historically, understanding winter weather has been difficult largely due to a lack of observations and, as a result, communities surrounding the Great Lakes have been left underprepared for extreme events.
