Targeted Monitoring Solutions in the Great Lakes

Great Lakes Research Center

The Great Lakes are in a state of rapid and continuous change resulting from a host of environmental and anthropogenic stressors. Such circumstances require unique, targeted monitoring solutions to meet environmental demands and continuously document these changes. Hayden Henderson, a research engineer with the Great Lakes Research Center (GLRC), designs such systems, working with research […]

A YSI EXO3 Multi-Parameter Water Quality Sonde is illustrated on the right with a line pointing to the left where an X3 is transmitting data waves to a cloud above which has a line to a phone screen on the far left which displays dissolved oxygen data on the screen in the WQData LIVE mobile app view.

YSI EXO Water Quality Sondes X-Series Integration Guide

The YSI EXO Multiparameter Sondes can simultaneously measure multiple water quality parameters, including conductivity, temperature, pressure, dissolved oxygen, and many more. It easily integrates with NexSens X-Series data loggers using the SDI-12 sensor interface. Sensor Setup Before the sensor can be deployed, it must first be set up through KOR software. For proper communication with […]

BS1 sampling platform in its deployed position. The site is powered by a solar-powered battery, connects to the WQDataLive cloud service with a cellular modem, and collects temperature, salinity, oxygen, chlorophyll, turbidity, pH, and weather parameters. The site is located between two oyster aquaculture facilities in Morro Bay, CA.

Water Quality Monitoring in Morro Bay

California Polytechnic State University, San Luis Obispo

Monitoring efforts in Morro Bay have been ongoing for decades, studying the inputs of the bay’s tributaries, the outputs of the bay, and water quality conditions over time. For the past 18 years, California Polytechnic State University, San Luis Obispo (Cal Poly, SLO) has managed various monitoring stations in the bay and estuary. The project […]

4.2 Flow

Water flow measurement builds on level measurement to provide not only water levels, but total volume in moving natural waterways, namely rivers and streams. Flow monitoring tracks the movement of water in a watershed and is a critical component of water resource management, hydropower generation, environmental conservation, and other hydrological studies. Flow rates in water […]

Geolux Non-Contact Flow Sensor X-Series Integration Guide

Real-Time Water Velocity and Flow Measurements The Geolux Non-Contact Flow Sensor measures water velocity and calculates overall flow in streams, rivers, and other water bodies. The sensors are compatible with the NexSens X-Series data loggers using the SDI-12 sensor interface and communication protocol. Parameter data is transmitted, in real-time, at a user-specified interval (e.g., 10 […]
