Questions & Answers
How does a Polarographic DO sensor work?
In a polarographic sensor, the cathode is gold and the anode is silver. The system is completed by a circuit in the instrument that applies a constant voltage of 0.8 volts to the probe, which polarizes the two electrodes. The sensor operates by detecting...
Why is the Polarographic sensor warranted for 1 year while the Galvanic is only warranted to 6 months.
Galvanic sensors continually consume the anode, even when the instrument is off. The consumption of the polarographic sensor stops when the instrument is turned off, giving it a longer sensor life.
Is this sensor approved by the EPA?
Yes, the proven technology of the steady-state sensor is approved by the US EPA for compliance monitoring and reporting.
How often should the dissolved oxygen sensor be calibrated?
The DO readings should be verified before each use, and a YSI recommends performing a 1-point calibration before each use to maintain accurate readings. You can follow the instructions in the calibration guide for dissolved oxygen sensors.

Mississippi Gulf Coast fish kill expected to continue

Officials at the Mississippi Department of Marine Resources say that a recent fish kill along the state’s Gulf coast is the largest they’ve seen, according to KVUE. The fish kill has brought dead crabs, eels and stingrays ashore. Beachgoers were disturbed by the large-scale kill, but experts explained that conditions this year were to blame. With higher temperatures and low dissolved oxygen near the sea floor, creatures that live there were more likely to be affected. The fish kill, beginning July 1, was the first of 2013 for the area. It was expected to last several more days, but lessen over that period.

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.
