Overview
The Global Water WQ401 Dissolved Oxygen Sensor is a rugged and reliable water oxygen measuring device. The WQ401’s sensor is attached to 25 ft of marine grade cable, with lengths up to 500 ft available upon request. The sensor’s output is 4-20 mA with a three-wire configuration. The sensor’s electronics are completely encapsulated in marine-grade epoxy within a stainless steel housing. The unit uses a removable shield and dissolved oxygen element for easy maintenance.

Mechanics
As with all of Global Water’s 4-20 mA output sensors, users can add recording and controlling capabilities to the WQ401 with the GL500 Recorder and PC320 Controller. The GL500 connects to the dissolved oxygen sensor’s 4-20 mA output to record data, and the PC320 Controller connects to the sensor’s output to control pumps or alarms.

Soundscapes of the Solar Eclipse: Citizen Science Supporting National Research

On April 8, 2024, millions of people around the world had their eyes glued to the sky to witness a historic cosmic event. The total solar eclipse captured the headlines and the minds of many who became eager to gaze at the heavens as the sky went dark for a few minutes. However, not everyone used their sense of sight during the eclipse, some were listening to the sounds of the natural world around them as the light faded from above. The Eclipse Soundscape Project is a NASA-funded citizen science project that focuses on studying how the annular solar eclipse on October 14, 2023, and the April 8, 2024 total solar eclipse impacted life on Earth.  The project revisits an initiative from the 1930s that showed animals and insects are affected by solar eclipses.

Applied Research and Innovative Solutions: Creating CHNGES at Western Kentucky University

Long-standing environmental monitoring programs have the power to support a large number of research initiatives and policy changes—however, actually starting these networks can prove challenging. Not only is starting the program difficult, but keeping things operational for decades to come has also been challenging for environmental professionals hoping to make an impact with applied research. Jason Polk, Professor of Environmental Geoscience and Director of the Center for Human GeoEnvironmental Studies (CHNGES) at Western Kentucky University, is all too familiar with this process.

Combating Water Insecurity in Saskatchewan with Real-Time Data

The prairies of Saskatchewan can be described as one of the least water-secure parts of Canada, making water quality monitoring essential for informed resource management in a region already facing water insecurity. While natural physical properties worsen some of the poor water quality conditions in the region, others are connected to land use. Having grown up spending summers on the shores of Lake Huron, Helen Baulch, an associate professor at the School of Environment and Sustainability at the University of Saskatchewan , has always been dedicated to the protection of water resources. Looking back fondly at her childhood playing along the shore, Baulch also recalls the invasion of quagga mussels during her teenage years and watching the lake change as a result.
