What's hiding at the bottom of Lake Superior? Michigan Technological University researchers are working to find out.
Michigan Tech's Great Lakes Research Center led a mission last September to map 45 square miles of Lake Superior's floor using cutting-edge autonomous surface vessel technology — part of a broader national initiative called Lakebed 2030, which aims to fully map all five Great Lakes at high resolution by the end of the decade. Only 15 percent of the Great Lakes' lake beds have been mapped at high density, and much of the existing data is decades old.
The effort is about more than discovery. Better maps mean safer navigation, stronger conservation, and a deeper understanding of the freshwater resources that 40 million people depend on for drinking water.
Michigan universities aren't just studying the Great Lakes — they're leading the charge to protect them.
