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
Formed by a glacier, Jordan Pond is among Maine's clearest, most beautiful bodies of water. It's also a critical freshwater resource, and watchful eyes are protecting it.
EM spoke with Dr. Rachel Fowler, Friends of Acadia's aquatic scientist, about her work monitoring Jordan Pond. A postdoctoral research scientist at the University of Maine, she is a member of a partnership among the National Park Service, the University of Maine Climate Change Institute, and Friends of Acadia that began deploying the Jordan Pond buoy in 2013. Canon provided the initial support for the project.
Friends of Acadia is a nonprofit organization that supports different projects in the park.Read More
River management is inherently complex, demanding mastery of constantly dynamic conditions even when the climate is stable. As the climate changes, however, river management will become even more difficult and unpredictable—and old models and techniques are likely to fail more often.
Now, researchers from around the world are calling for attention and change to how we manage and model the rivers of the world. Dr. Jonathan Tonkin , a Rutherford Discovery Fellow at New Zealand's University of Canterbury , spoke to EM about why he is arguing that current tools for river management are no longer enough as even historical baseline river ecosystem conditions themselves are changing.
