NASA & NOAA Just Revealed What's Hiding Under the Great Lakes

In this DiscoverTube documentary, we uncover 20 extraordinary discoveries, from a connected freshwater system holding roughly six quadrillion gallons of water to hidden groundwater, underwater sinkholes, ancient landscapes, microbial ecosystems, and shipwreck graveyards.

Scientists are using NASA satellites, NOAA sonar, ROVs, and chemical sensors to reveal what lies beneath the surface. The Great Lakes contain about 21% of the world's surface freshwater, yet researchers are still discovering new connections between their geology, biology, and hidden water systems.

From ancient hunting grounds beneath Lake Huron to mysterious sinkholes and lost shipwrecks, the Great Lakes are hiding far more than most people realize.
What could still be waiting at the bottom?
