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
Engineers and scientists that specialize in aquatic measuring practices always meet extra costs on the path to deployment. Maybe it is the corrosive nature of the saltwater, or the unbearable pressure tools must be equipped to handle while lying on the ocean floor.
For anyone interested in hooking up with the MARS (Monterey Accelerated Research System) Observatory , which rests dozens of miles off the California coastline, the costs extend further. They get so high that only well-funded universities and governmental agencies can afford to connect with the underwater power and data hub.
Hoping to lower that cost, engineers with the Monterey Bay Aquarium Research Institute ( MBARI ) constructed a wireless device called Deep-Sea Connect.Read More
During an electronic monitoring conference in February, fisheries managers and fishermen watched a squiggly purple line meander across the screen. It was mapping the journey a tuna fish was taking, from being caught and landing across the deck of a fishing vessel.
Leigh Habegger, executive director for Seafood Harvesters of America , a national commercial fishing group, said everyone in the crowd had their eyes glued to the screen.
“It was fascinating, it was really cool,” she added.
The graphic was the manifestation of a machine-learning tool that was trained to follow where a fish ended up after it was caught.Read More
