Wisconsin watershed program involves high schools to collect, share data
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. Populations of local frog and bird species are also tracked.
Ohio city sleuths for illegal discharges to streams
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.” Schelle oversees the ambitious project for Springfield.
Testing CO2 Removal Strategies in the Pacific Northwest
The ocean plays a key role in carbon dioxide (CO2) removal and storage, also known as carbon sequestration. However, with increasing emissions, a large amount of CO2 escapes into the atmosphere, worsening climate change and leading to increases in surface temperatures. In order to mitigate some of these impacts, researchers like Ally Savoie at the Pacific Northwest National Laboratory (PNNL) are working hard to identify ways to safely improve the CO2 removal and storage capabilities in the ocean. Savoie started her career at Wright State University , where she worked in Silvia Newell’s lab examining biogeochemical cycling of nutrients in a river system. From there, she decided to pursue a master’s in marine science at the University of Southern Mississippi with Dr.
Smart Buoys Advance Climate Monitoring in Swiss Lakes
Lakes are sentinels of climate change . Globally, they are warming at an unprecedented but uneven rate, and in many places they also face direct human pressure, including from agriculture and recreation. In the Alps, scientists generally agree that climate change is of particular threat to remote lakes , where more pronounced warming threatens fragile ecosystems. Alpine Lakes in a Changing Climate Matteo Tonellotto is part of the team at the Environmental Observatory of the Italian-speaking region of Switzerland (OASI)–a multidisciplinary team of scientists, IT specialists, and chemical laboratory technicians committed to collecting, managing, and integrating high-quality environmental data.
