Freshwater filmmakers and explorers Zach Melnick and Yvonne Drebert are teaming up with Thunder Bay National Marine Sanctuary and Great Lakes Now for the first-ever livestream from Middle Island Sinkhole, an underwater time capsule that plunges 80 feet below the surface of Lake Huron. Using a high-tech remotely operated vehicle (ROV), the team will descend into the sinkhole, following advanced divers as they collect samples from the remarkable microbial mats at the bottom.
Get an up-close look at the sinkholes colorful bacterial communities, vast carpets splotched with shades of purple, brown, and white. Scientists believe this globally significant ecosystem can provide insights into how life evolved on Earth and how the planet’s first oxygen producing organisms transformed the atmosphere.
Along for the journey will be Dr. Bopaiah Biddanda from Grand Valley State University, an Aquatic Microbial Ecologist who has spent years studying the sinkhole’s unique ecosystem. Sarah Morrison, Media Specialist at Thunder Bay National Marine Sanctuary, will share how the sanctuary supports researchers looking to uncover the secrets of the sinkholes.
Biddanda, Morrison, Melnick, and Drebert will answer audience questions in real-time during the dive.
