Great Lakes exploration: Insights into Lake Superior and Lake Michigan

Lake Superior, the largest freshwater lake in the world by surface area, remains a subject of significant scientific interest. In 2026, researchers utilized a submersible robot to explore the Superior Maximus, the lake's deepest point at 1,332 feet. This expedition followed a 1985 mission by the University of Wisconsin-Milwaukee and the placement of a time capsule intended for opening in 2037. Findings from the 2026 survey indicate a sterile, moon-like environment at the bottom with very little life, though some unique species were captured on camera alongside human debris.

Lake Michigan, another member of the North American Great Lakes, is noted as the fifth largest lake in the world by surface area. It is distinguished as the largest lake that is contained entirely within a single country, the United States. Spanning over 58,000 km2, the lake is central to the economies of cities like Chicago and Milwaukee and is known for its crystalline waters and extensive shorelines.
