In the mid-1980s, a state-of-the-art submersible allowed scientists to see the Great Lakes like never before.
The Johnson Sea Link II was equipped with arms and cameras that allowed researchers to collect samples and create detailed records of their findings. A plexiglass bubble gave the passengers a panoramic view of the lakebed.
On July 30, 1985, the JSL II carried the first passengers to the deepest point in the Great Lakes, more than 1,300 feet beneath the surface of Lake Superior. Another visit in 1986 would leave a time capsule. After that, no one would return for 40 years.
