MARQUETTE — Lake Superior’s ice coverage has greatly surpassed expectations this year.
Earlier in the season, forecasters predicted the lake would reach a little more than 50 percent ice coverage this winter. But as of Friday, Lake Superior was over 85 percent covered, far exceeding the prediction and the lake’s long-term average of 55 percent, according to the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Laboratory, or GLERL.
This year’s frigid conditions triggered the rapid expansion of the ice that exceeded predictions, said Jia Wang, a research ice climatologist and physical oceanographer at GLERL.
