Olaf Jensen, an associate professor at the University of Wisconsin-Madison’s Center for Limnology, studies fish, fishing and fishery management. He said what’s more exciting to him is what lies under the surface.
“It’s a glimpse into that mystery of life under the ice when you go ice fishing,” Jensen said. “You realize that life goes on under the ice. Lakes don’t just go to sleep for the winter and wake up again when the ice comes off.”
