“The major threats to all the lakes include invasive species that throw a delicate ecosystem out of balance. In Erie, more so than the other lakes, toxic algae threaten the health of visitors and create “dead zones” where no aquatic species can survive.At least 136 invasive species — plants, fish and mussels — have forever changed the lakes. But it’s the potential 137th invader that officials fear the most. The Asian carp wants nothing more than to spread through the Great Lakes and continue its feeding frenzy. Though a live fish has yet to be found, DNA tests suggest that they might already have infiltrated Lake Erie.”

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!
