LANSING — Diving isn’t the only way to get an in-depth look at the mysteries beneath the surface of the Great Lakes. Lasers, underwater robots and other innovative technologies are simplifying the discovery of and research about hundreds of shipwrecks at the bottom of the Great Lakes. Thunder Bay National Marine Sanctuary, a part of the National Oceanic & Atmospheric Administration (NOAA), is a 4,300-square-mile shipwreck sanctuary in northwestern Lake Huron near Alpena. It has one of America’s best-preserved and nationally significant collection of shipwrecks. There are 92 known wrecks in the newly expanded sanctuary, and four have been listed on the National Register of Historic Places, said Sarah Waters, the education coordinator at the sanctuary.
