“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.”

August 22nd, 2012 by Irene MilesIn the news: New barrier could help control sea lampreys near Lake Michigan
August 16th, 2012 by Irene Miles“That will allow the federal government to build a new barrier there to keep sea lampreys from breeding in the river. Managers of the fishery expect that will bring the lamprey problem under control in Lake Michigan.”
Classroom specimens require caution and care to prevent becoming invasives
August 14th, 2012 by Irene Miles“The study, led by Oregon Sea Grant Extension’s invasive species expert Sam Chan, was presented at this week’s national meeting of the Ecological Society of America in Portland.‘Live organisms are a critical element for learning and we don’t want to imply that they should not be used in the classroom,’ said Chan. ‘But some of our schools – and the biological supply houses that provide their organisms – are creating a potential new pathway for non-native species to become invasive.’”

“The Great Lakes National Program Office (GLNPO) of the U.S. Environmental Protection Agency (USEPA) is responsible for monitoring the offshore water quality of the Great Lakes to evaluate water quality over time and identify any emerging water quality problems. Comprehensive water quality surveys are conducted in all five Great Lakes in both the spring, when the water is cold and well mixed, and in the summer, when the lakes are biologically active. The R/V Lake Guardian is currently being used to conduct the summer water quality survey.”

August 6th, 2012 by Irene Miles“The transformation is already underway and over the next few years, the factory will become a zero-energy, food business incubator, research facility, education space, and working urban farm. Plant Chicago is already growing greens and mushrooms and will soon start brewing beer and kombucha and raising tilapia in a sustainable system with zero waste.”
Students Learn about Coastal Issues in the Pacific Northwest from Sea Grant Specialists
August 3rd, 2012 by Irene MilesBill Hanshumaker of the Hatfield Marine Science Center and Oregon Sea Grant explains aquaculture research being conducted at the facility. |
Each year, natural resource students from Purdue University, North Carolina State University, and the Swedish University of Agricultural Sciences come together to learn about sustainable use of natural resources in some part of the world. In July 2012, the course took place in the Pacific Northwest. Students visited old-growth forests, wildlife refuges, urban areas and more, learning about the political, social and economic concerns that factor into decision-making and development in the region.

IISG’s Carolyn Foley shares more about the course: “Amidst glorious sunshine, students learned about the strong fishing trade in Newport, OR, including oyster farming. They asked questions about how these trades are regulated in the Pacific Northwest, and what impacts their activities have on the surrounding community and natural resource use. They were also able to visit the Hatfield Marine Science Center and gain a healthy overview of the major issues affecting coastal resources in Oregon and surrounding states, including the development of technology to harness wave energy, impacts of naturally-occurring low-oxygen conditions, and effects of development on local wildlife populations. Some students even visited a large dock (~66’ x 19’ x 7’) that was ripped from its pilings in Misawa, Japan during the 2011 tsunami which crossed more than 11,000 km of Pacific Ocean and landed near Newport in early June, bringing with it more than 80 non-native, potentially invasive species of algae, snails, clams, and other life forms.”
Students from the course gather in front of the tsunami-generated floating dock that washed ashore in early June 2012. Researchers have identified 92+ species that survived the trans-Pacific voyage. |

In the news: New Illinois law helps prevent spread of AIS
August 2nd, 2012 by Irene MilesAs an amendment to the Boater Registration and Safety Act signed into law by Illinois Governor Pat Quinn, aquatic plants and animals would need to be removed from seaplanes and watercraft before moving between bodies of water. The requirement is an important step in preventing the spread of aquatic invasive species throughout the state of Illinois, as well as between states and bodies of water where these vehicles might travel.

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.

@brosenstock

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!
