The Grand Valley State University Wind Sentinel research buoy, one of only three in the world, will be returned to Lake Michigan this month. It will be placed about seven miles offshore, northwest of the Muskegon Channel, for its third research season. The project is running short of funding, and its future activities beyond this year are uncertain. Project partners include researchers from: Michigan Technological University, who are studying wind turbulence; Michigan Natural Features Inventory, a component of the Michigan State University Extension program, who are studying bird and bat activity (and who confirmed for the first time ever last summer that bats do fly over the Great Lakes); and the University of Michigan, who are conducting research on large data sets.
