Screen cap from the beginning of a paywalled Detroit News article titled “Federal Layoffs would gut Great Lakes fisheries research center.” Posted in Oct 20, 2025 at 9:25pm and written by Melissa Nann Burke. It reads “Washington - the U. S. Geological Survey is planning to lay off 79% of the workforce of the Great Lakes Science Center that’s headquartered in Ann Arbor as part of a reduction in force across the U.S Department of the Interior, officials say.”
