“Plant species were chosen based on the results of a risk assessment tool developed in Indiana by the Aquatic Plant Working Group. The tool evaluates species based on factors like ability to thrive in the Great Lakes and difficulty to control. At the request of Indiana Department of Natural Resources, Illinois-Indiana Sea Grant organized and facilitated the group, which included representatives from the aquatic plant industry, aquarium and water garden hobbyists, state agencies, academia, and non-governmental organizations. Their efforts led to a rule approved last year that bans the sale of 28 invasive aquatic plants in Indiana.‘It is important to have consistent regulations across the Great Lakes Basin. We want our policies to be consistent with our neighbors since invasive species don’t respect political boundaries,’ said Kevin Irons, aquaculture and aquatic nuisance species program manager for Illinois DNR. ‘Prevention is the first and cheapest way to protect Illinois from aquatic invasive plants, and risk assessment tools like the one built in Indiana allow us to identify and control high risk species without unduly regulating the industry.'”

The Shipboard Science Immersion educators worked together to simulate sonar mapping and uncover the secrets of a mystery seabed, just like real underwater archaeologists!
This hands-on lesson mirrors the work of Dr. Ashley Lemke from University of Wisconsin Milwaukee who studies paleo landscapes below Lake Michigan by collecting sonar data from lakebeds. Experiences like these can be shared with youth to spark curiosity and connect them to real-world science in action.

15 educators from 7 Great Lakes states have boarded the R/V Lake Guardian for a week of science on Lake Michigan!
Day one was all about meeting fellow educators and the science team from the @epa_greatlakes, @uwmilwaukee, and @purduefnr, and getting shipboard safety training.
This hands-on program, supported by the Great Lakes Restoration Initiative, helps bring Great Lakes science into classrooms and builds educator-scientist partnerships.
Follow along as we explore water quality, food webs, and even underwater archaeology!
