Epic summer adventure? Try splashing in all five Great Lakes in one day. Here are three routes you can try, including a no-passport way.

The Great Lakes mapping effort will pinpoint hundreds of shipwrecks, illuminate topographical features and identify fisheries, a marine scientist said.

We know less about the bottom of the Great Lakes than we do about the surface of Mars, according to Jennifer Boehme. The oceanographer is executive director of the Great Lakes Observing System, an ...

Only a fraction of the Great Lakes' bottom has been mapped, and the available charts, completed decades ago, are low-resolution.

A map of the Great Lakes’ bottoms would benefit insurance companies, the shipping and fishing industries, construction projects and more.

Now, 40 years later, Boehme wants to launch another treasure hunt. As executive director of the Great Lakes Observing System, she's leading a campaign to map every meter of the lakes' bottom. The ...

The Great Lakes map would provide fuller images of bottom features that have changed in the last 50 years due to erosion and shifting sands, giving navigators new depth findings that would improve ...

Researchers at Michigan Tech's Great Lakes Research Center are leading a collaborative effort to map the lake beds of the Great Lakes at high resolution for the first time—a giant leap forward in the ...

The last effort to map the lakes came in the 1970s. Maps were largely created using single-beam sonar technology similar to today’s commercially available depth- and fish-finders.
