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
Climate change-driven volatility is changing lakes at the base of their food webs.
That’s one way to interpret new research that documented such a change in Muskegon Lake on the coast of Lake Michigan. Researchers found that, in one particularly rainy and cool year, normal phytoplankton diversity and patterns were cast aside. Instead, one group of algae dominated the entire year, offering a glimpse into the kinds of surprising changes that could happen in the future.
“Phytoplankton are a very responsive group of organisms,” said Jasmine Mancuso, whose research detailing the change in the lake was published in October in Journal of Great Lakes Research .Read More
While researchers all over the globe have been studying greenhouse gases, there are still some areas in the field that have not received as much attention as they deserve. Emily Stanley, professor in the department of integrative biology at the University of Wisconsin and principal investigator for North Temperate Lakes Long Term Ecological Research (NTL-LTER), has spent a significant part of her career exploring a few of them.
“Clearly we have a problem with greenhouse gases. What people may not realize is that streams and lakes are hotspots of global methane and CO2. Understanding greenhouse gas dynamics in these systems is important because they are vents all over the world and they are not insignificant,” said Stanley.Read More
