"TRAVERSE CITY, Mich. — What’s happening in the Great Lakes during those long, frigid months when they’re often covered partially or completely with ice? A casual observer — and even experts — might be inclined to say, “Not much.”
Lake scientists have long considered winter a season when aquatic activity slows. Most do their field studies at other times of year.
But researchers now think more is going on in the bitter depths than previously believed — including activity influenced by climate change. To learn more, teams will venture onto the frozen surfaces of all five lakes this month to collect water samples and other information from below the ice.
“We’ve been ignoring winter on the Great Lakes for so long,” said Ted Ozersky, a lake biologist with the University of Minnesota Duluth, who announced the “Winter Grab” expedition Thursday."
