“Scientists doing an offshore fish survey had noticed an anomaly on their sonar readout, basically an unusual bump on an otherwise flat lakebed,” Melnick said in a press release. The couple, who specialize in underwater videography, grabbed their ultra-low-light, high-resolution camera system, and journeyed out to the site of the anomaly, expecting to find “a pile of rocks.”
Instead, when their remotely operated vehicle descended 85 meters, “a huge structure loomed up from the depths — it was a shipwreck. We couldn’t believe it,” Melnick said.
The wreck was difficult to identify — images from the filmmakers show the ship is covered by the invasive quagga mussels that have been overhauling the ecosystem of the Great Lakes.
But the filmmakers said that with the help of a local maritime historian and a marine archaeologist, the “Africa” emerged as the likeliest possibility. The vessel’s measurements matched that of the “Africa,” plus Melnick and Drebert saw coal scattered across the lake bottom near the wreck.
“There are so many quaggas filtering the Great Lakes, that the lakes are up to three times as clear as they were before the mussels,” Drebert said in the press release. “The quaggas are the reason we’re able to see the shipwreckin almost 300 feet of water without any additional lights. But they’re also responsible for making wreck identification in the Great Lakes incredibly difficult.”
The couple’s documentary, “All Too Clear: Beneath the Surface of the Great Lakes,” will be released in early 2024.
