What Is The 'Winter Grab' Along The Great Lakes?
Newsy
For the first time, scientists are collecting lake samples during the winter to better understand global warming.
Scientists from dozens of U.S. and Canadian groups are making history this week.
For the first time ever, they are working jointly to collect winter samples of all five Great Lakes, braving the elements to study how global warming is impacting the largest freshwater ecosystem on Earth.
"This coordinated campaign across all five lakes was really special," said Casey Godwin, an assistant research scientist for Cooperative Institute for Great Lakes Research at the University of Michigan. "You're going for an exciting snowmobile ride, and one of the first things we do is we make measurements of how deep the snow is. And then shortly after that, we're getting to making a hole. Once we have those holes, we can begin to put our instruments into the water."
