LANSING – Maritime archaeologists are swapping shipwreck surveys for lake trout mapping in Lake Huron. And they’re using sound waves to do it. “Consider it double-dipping. The sonar on research vessels could map an area of interest for shipwrecks while also helping out some biologists,” said Russ Green, program coordinator at Thunder Bay National Marine Sanctuary in Alpena. The biologists say they want to use the results in lake-wide rehabilitation of trout habitat.
