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.

Researchers Track Glacial Meltwater On Its Surprising Journey

While the scientific community has formed its consensus on how ice sheets are shrinking in and around Greenland, some researchers are tracking what happens to the meltwater as it drains into the ocean each summer. Their study, published in Nature Geoscience by an interdisciplinary team of biologists, oceanographers and hydrologists, used computer models to simulate the meltwater to see where currents take it and what effect it could have on the ocean. Renato Castelao, one of the researchers and an associate professor of marine science for the University of Georgia, said one of the biggest discoveries of the study was the surprising final destinations of the ice sheets as they melt into the ocean each summer.

Ice Fishing With A SondeCAM Underwater Fishing Camera

Thinking of hitting the ice with a SondeCAM underwater fishing camera? Due to its rugged design, you won't have to worry about it handling the harsh elements. However there are a few simple tricks to get the most out of a FishSens SondeCAM while ice fishing. You won't have to do anything to modify the SondeCAM itself, but you are going to have to bring a few extra things. Most importantly we are going to need a power source. Unless you are hauling your gear with a truck, you'll want something more portable than the battery you used in the boat. Pick up an inexpensive and maintenance-free 12-volt, 9-amp battery. It is going to provide plenty of power, but will be much lighter and take up less space.
