Have you ever wanted to explore Great Lakes shipwrecks and the underwater life that lives around them? Now you can, right from home! This recent feature from Detroit Public TV’s Great Lakes Now program introduces viewers to the world of shipwrecks in NOAA’s Thunder Bay National Marine Sanctuary, as well as their relationship with the surrounding natural environment. Originally recorded on October 12, 2020, Great Lakes Now Program Director Sandra Svoboda talks with NOAA GLERL Research Ecologist Ashley Elgin and NOAA Maritime Archaeologist Stephanie Gandulla about this unique sanctuary in northern Lake Huron.
Elgin discusses some of the fascinating ways that these shipwrecks intersect with the ecology around them, from the impacts invasive species have on the wrecks to the differences in fauna surrounding shallow wrecks versus deep ones. Gandulla focuses on the historic perspective of the sanctuary and its shipwrecks, helping viewers dive into the “history under the waves” with underwater footage of the shipwrecks themselves.
The video also features a preview of the new PBS documentary series Age of Nature, which leads Elgin and Gandulla to discuss the differences between shipwrecks and their ecosystems in the ocean and the Great Lakes. Watch the full video below!
