“For decades, the mathematics of waterborne transport here were simple. For every 10 to 11 metric tons of cargo that moved into and out of the Toledo port, about one metric ton of sediment left the channel. (Last year, 10.4 million metric tons of cargo were handled at the port.)But with climate change, the equation is almost certain to get more complex and more expensive, say scientists and port managers. More mid-winter snow melts and rainstorms — and more frequent heavy rainfalls, especially in spring — may lead to higher soil-erosion rates, meaning that Great Lakes rivers are likely to carry more soil into harbors. Higher air temperatures already are warming the Great Lakes, blocking ice from forming, and increasing rates of evaporation that may lead to lower lake levels.”

This summer, 15 Great Lakes educators swapped lesson plans for life jackets as they boarded the Lake Guardian, the U.S. Environmental Protection Agency’s research vessel, and set sail on Lake Michigan. Through the Shipboard Science Immersion program, 5–12 grade formal and non-formal educators worked side by side with Great Lakes scientists for a week—an experience they say will ripple back to their classrooms for years to come.

Last month, Illinois and Indiana educators gathered for a two-day, professional learning workshop hosted by @duneslearning, @indianadnr, @thengrrec, and Illinois-Indiana Sea Grant to dive deep into water’s role in Earth’s systems
Using @projectwet’s newest guidebook, Water in Earth Systems, participants explored the unique ecosystems of @indianadunesnps and engaged in hands-on aquatic science activities—bringing Great Lakes learning to life in the classroom!
Thanks to all who joined us in connecting science, stewardship, and the Great Lakes!

Shorelines never stop moving.
Our new video series, Shaping the Shoreline, shows how water levels, waves, storms, sediments, and structures like revetments, seawalls, and groins shape the Great Lakes coast.
Clear, quick videos designed for coastal decision makers and anyone curious about coastal change.
