The Great Lakes research area focuses on the five interconnected freshwater lakes located in North America: Superior, Michigan, Huron, Erie, and Ontario. Researchers study various aspects of the lakes, including water quality, ecosystems, fisheries, climate change impacts, invasive species, and environmental management. The Great Lakes are of significant ecological and economic importance, providing drinking water for millions of people and supporting diverse wildlife habitats. Research in this area aims to understand and address threats to the health of the lakes and develop sustainable management practices to protect and preserve this valuable resource.
