The Great Lakes – the largest bodies of fresh water in the world – are a vast resource for biologists, zoologists, historians, and humanitarians. While the Lakes contain many secrets yet to be discovered, we know now that invasive species as zebra mussels and quagga mussels are very harmful to their delicate ecosystem, and to their shipwrecks. Great Lakes shipwrecks do not become encrusted with the marine growth found on shipwrecks lost in sea water – but they do become encrusted with these invasive species.
Great Lakes Shipwrecks are underwater cultural resources vital to our study. The proliferation of invasive species has now created a time deadline for our generation and for future generations; many shipwrecks have already had so many of their features corrupted by mussels that they have become impossible to study.
One of the primary missions of the Great Lakes Shipwreck Historical Society is to locate, identify, and document historic Great Lakes Shipwrecks, with an emphasis on Lake Superior, before they are lost to these invaders. Please click here to view information about our latest documentation project.
The Shipwreck Society actively supports efforts by Lake Superior State University to study Great Lakes biology with underwater sensing equipment found on the Society’s R.V. David Boyd.
