The 4 factors that have led to a ‘golden age’ of discovery for Great Lakes shipwrecks [Video]

There’s never been a better time to find, explore and document shipwrecks on the Great Lakes, thanks to a combination of technology, environmental change and surge in public interest, according to those who uncover the sunken history of the world’s largest lakes.

The University of Buffalo estimates more than 6,000 shipwrecks are on the bottom of North America’s five Great Lakes, which, since the late 1600s, have been lost in wars, accidents, or frequent and powerful storms.

In the last 18 months, three previously unknown Great Lakes shipwrecks have made headlines around the world, from the steel bulk freighter Huronton, the 19th-century cargo steamer Africa, and in February, the Second World War-era freighter Arlington.

Explorers say the pace of new discoveries has quickened, thanks to new technologies, climate change, invasive species and a surge in public interest.
