A group of high schoolers in the Green Bay, Wisc. area are learning about careers in environmental science thanks to the Lower Fox River Watershed Monitoring Program . The program, supported by the University of Wisconsin, has involved more than 700 students since its 2003 launch.
“We have almost ten years of data,” said Annette Pelegrin, program coordinator. “It began in 2003 with five watersheds. We’ve trained teachers and schools that are interested and showed them how to measure different parameters.”
Those include flow, temperature, transparency and turbidity of the program’s streams. YSI 55 meters are used to measure dissolved oxygen and levels of phosphorus, ammonia and nitrogen are checked with a Hach colorimeter.Read More
Springfield, Ohio, a college town of 60,000 in southwestern Ohio, sits on the confluence of the Mad River and Buck Creek. Springfield’s streams are as much a part of the city as is Wittenberg University. The streams and the university’s brick infrastructure stand as a constant backdrop to the action of the community but do not often draw attention themselves.
Over the next year, however, Springfield will be paying close attention to its waterways in an effort to eliminate illegal discharges.
“The city is required to determine the location of every pipe that enters Springfield’s streams,” said Sky Schelle, the stormwater coordinator for the city of Springfield. “If a pipe is flowing, we must determine the source of the flow.Read More
Is eradicating Great Lakes sea lamprey an “impossible dream?” Researchers say no
The sea lamprey’s days in the Great Lakes could be numbered.
That’s according to one researcher who took one of the first scientific looks at the possibility of sea lamprey eradication in the Great Lakes.
So, can you remove enough sea lamprey to make them disappear?
“Well the answer is we already have,” said Michael Jones, emeritus professor of fisheries and wildlife at Michigan State University. “Then there’s the obvious question: Why are they still here?”
While multiple gaps in current management techniques, like sea lamprey poisons called lampricides, could account for sea lamprey’s persistence in the Great Lakes, new technology could help sea lamprey managers eliminate inaccessible populations.Read More
