Rising freshwater acidification levels have the potential to severely impact the Great Lakes environment. In 2022, scientists began an important research initiative to monitor acidification levels in Thunder Bay National Marine Sanctuary. The research will improve our understanding of lake acidification and its potential impacts to natural and maritime heritage resources in the Great Lakes. The data generated from this ongoing research in Thunder Bay sanctuary will result in the first baseline study specific to freshwater acidification in Lake Huron. During this webinar, learn about the working partnership with NOAA’s Ocean Acidification Program and the Great Lakes Environmental Research Lab, Thunder Bay sanctuary, and the local northern Michigan community. Find out what freshwater acidification is, why we should care, how acidification research is conducted, and how the community is involved in this effort to create a baseline of data. We will also discuss resilience to climate change in the Great Lakes.
