Great Lakes Integrated Sciences and Assessments (GLISA) is like a big group of grown-up scientists who work together to learn more about the Great Lakes. They study things like the water, the air, and the creatures that live in and around the Great Lakes.
They use all sorts of cool tools and machines, like special cameras and sensors, to collect information about the Great Lakes. They also talk to people who live near the Great Lakes, like fishermen and farmers, to learn more about how they use the Great Lakes and how it affects their lives.
GLISA then takes all this information and figures out how it could affect the Great Lakes in the future. For example, if lots of people start using the Great Lakes more, like by fishing or swimming, GLISA wants to make sure that the water stays clean and healthy for everyone.
GLISA also helps share this important information with other grown-ups, like government officials, so that they can make good choices to help protect the Great Lakes for a long, long time.
