Whether they’re in oceans or the Great Lakes, shipwrecks create unique ecosystems for a variety of aquatic life. They also have historical significance and provide recreational opportunities for divers, snorkelers and boaters.
Scenes of them open the PBS documentary series “The Age of Nature,” which broadcasts on PBS stations across the country in October 2020.
