Research Team Measures Physical, Chemical and Biological Activity in Lake Michigan page 2 The researchers, headquartered at the Center for Great Lakes Studies at the University of Wisconsin-Milwaukee, have, for the past two years, taken regular water samples from locations in the Milwaukee Harbor and out into the open waters of Lake Michigan near Milwaukee. From these samples, the researchers collect a variety of clues including rates of algal and bacterial growth and productivity as well as concentrations of dissolved oxygen and carbon dioxide. These clues help build a picture of how ecosystem changes, whether natural or human-caused, affect the lake's coastal zone. That's important because the physical, chemical and biological activity in the waters of this area of Lake Michigan can actually help eliminate some pollutants. This area of the lake also serves as a critical nursery area for important commercial fish such as yellow perch. |
