The first round of sampling revealed that the Lakes are home to between 1,500 and 1.7 million plastic particles per square mile, with Lake Erie housing the largest concentrations. Dr. Sherri “Sam” Mason of the State University of New York (SUNY) at Fredonia, Dr. Lorena Rios-Mendoza of University of Wisconsin, and Dr. Marcus Erikson of 5 Gyres Institute have determined that much of the plastic they found was actually microbeads, found in many brands of toothpaste and facial and body scrubs. These tiny pieces of plastic are less than a millimeter in diameter, much too small to be filtered out by wastewater treatment facilities before that water is released into nearby lakes and rivers.

Research mission beginning today looks into microplastic pollution of the Great Lakes
August 8th, 2013 by Irene MilesIn the news: Finding a better way to get rid of unwanted algae
August 6th, 2013 by Irene MilesEach year, Great Lakes beach managers have to remove trucks full of slimy algae from the beachfront areas to keep them enjoyable for residents and visitors. But it can be a costly process and a regular need that could be met in a more environmentally friendly way.
From The Great Lakes Echo:
“Truckloads of the stuff are hauled to landfills every week or so, but beach managers want a greener and cheaper method of disposal.‘Algae removal is sort of a routine beach-grooming thing that we do, but because it’s wet and heavy, it can be expensive to dispose of,’ said Cathy Breitenbach, director of Green Initiatives for the Chicago Park District, which is responsible for 26 miles of lakefront in the city. She’s hoping to find an alternative that saves taxpayers money and is more sustainable than taking it to the dump like the district does now.Composting may seem like an obvious solution, but it’s not as simple as it sounds, say algae experts. Cladophora mats can harbor large concentrations of bacteria, including some potentially dangerous varieties.‘We have evidence to show that E. coli bacteria are found in very high densities in Cladophora mats,’ said Murulee Byappanahalli, a research microbiologist at the U.S. Geological Survey’s Lake Michigan Ecological Research Station in Porter, Ind.”

August 5th, 2013 by Irene MilesIn the news: U.S. House panel suggests significant cuts to Great Lakes programs
July 26th, 2013 by Irene MilesA House panel has suggested some deep cuts to Great Lakes programs including the Great Lakes Restoration Initiative, but a number of congressional members are ready to oppose such cuts and continue the restoration and protection work on each of the Lakes.
From Crain’s Detroit Business:
“Federal programs designed to make headway on some of the Great Lakes’ most longstanding ecological problems, from harbors caked with toxic sludge to the threat of an Asian carp attack, would lose about 80 percent of their funding under a spending plan approved Tuesday by a Republican-controlled U.S. House panel…After an initial $475 million in 2009, the restoration initiative has gotten about $300 million a year, although this year’s total has fallen to $285 million because of across-the-board cuts. The subcommittee bill would slash the 2014 allocation to just $60 million.The Great Lakes region historically has received about one-third of the money in the federal loan fund for sewer repairs. Sewer overflows cause local officials to order beach closings each year because of E. coli bacteria contamination. The bill would reduce the fund from just over $1 billion this year to $250 million in 2014…The restoration initiative has pumped about $1.3 billion into projects across the eight-state region that have helped scrape away contaminated harbor sediments, restored wildlife habitat and sought to curb runoff that causes harmful algae. It also has supported efforts to ward off an invasion by the dreaded Asian carp, which compete with native species for food.”
In the news: Illinois senators help strengthen the state’s Asian carp prevention efforts
July 24th, 2013 by Irene MilesSenators Mark Kirk (R) and Dick Durbin (D) of Illinois recently passed an amendment that would prevent the Army Corps of Engineers from moving critical invasive species prevention functions out of their current Chicago location .
From CBC News:
“An amendment to the Energy and Water Appropriations bill has passed and prevents the removal of critical functions and staff from the District Office of the U.S. Army Corps of Engineers in Chicago. The Windy City is home of the frontline fight against Asian carp entering the Great Lakes.
Republican Senator Mark Kirk and Senator Richard Durbin, a Democrat, proposed the amendment after U.S. Army Corps of Engineers announced plans to move Chicago district office functions to Detroit.
The senators believe the move, had it been made, would have potentially affected more than 200 employees who oversee projects such as Asian carp electric barriers and Chicago locks and dams designed to keep the invasive species out of the Great Lakes.”

Teachers tackle Great Lakes science and take lessons back to their classes

Funding was provided through a grant from the NOAA B-WET education program (linked above), and the workshop was made possible with assistance from Indiana Dunes State Park, the Great Lakes Research and Education Center at Indiana Dunes National Lakeshore, and the Alliance for the Great Lakes.
In the news: Great Lakes under growing pressure as water needs grow
July 15th, 2013 by Irene MilesThe Great Lakes, a source of freshwater for millions in American and Canada, will likely see increased stress as the water is needed for a growing population and a changing climate.
From The Toledo Blade:
“The Lakes’ usage has drawn more attention in recent years from politicians and legal scholars, such as those who attend the University of Toledo College of Law’s renowned Great Lakes water-law conference each fall. They have stated on numerous occasions that Great Lakes water-management laws pale in comparison to those of the American Southwest, where political battles over water rights have been fought for decades.
Scholars believe this region’s legal framework is evolving into a stronger one as water controversies and more political battles heat up, as evidenced by intense negotiations that resulted in the Great Lakes region’s first binding water-management compact.The Great Lakes region has traditionally been less irrigated than others. But that too is changing.
Michigan and Ohio have had an uptick in irrigation permits the past two years, largely a result of the 2012 drought and concerns over weather becoming more unpredictable because of climate change.”

Teachers and scientists give high marks to IISG’s Educator Day at IAGLR 2013
July 10th, 2013 by Irene MilesFrom Robin Goettel, IISG associate director for education:
Scientists and teachers had a unique opportunity to interact, network, and connect research with education during The Center for Great Lakes Literacy’s Educator Day at last month’s IAGLR 2013 conference in West Lafayette, Indiana. Among the many goals of the IISG-coordinated session, providing opportunities for teachers to share their science education needs with researchers and identifying ways to incorporate the latest Great Lakes research into their lesson plans were high priorities.
The exchange of ideas was not only productive, but was a welcome and highly valued experience for all of the participants. The feedback received from both researchers and educators was outstanding, and offered a number of suggestions to guide another session like this in the future.
Said one teacher of the event, “I was impressed! My experience with IAGLR exceeded my expectations. I was hoping to simply gather more information to ‘grow’ my Great Lakes curriculum. However, I was able to network with other teachers and scientists which I found so much more valuable than walking away with a stack of Great Lakes lesson plans.”
Another educator was grateful for the opportunity to meet and talk to working researchers. “I am very thankful for the chance to interact with professionals in the field. Not only does attending scientific conferences refresh learned concepts, but allows for new learning, insight, and expansion of awareness. It also provided fresh ideas for project-based learning and the opportunity to network with potential collaborators.”
The participating scientists were also glad to brainstorm ways that their work could be incorporated into classroom lessons.
“I always enjoy talking with teachers who are ‘in the trenches’ with younger students. They are faced with a different set of challenges (and opportunities) than we have at the college level. It was nice to hear that there are current efforts to better integrate math and science. It was also interesting to hear what teachers introduce in their classrooms to motivate and engage students in STEM areas.”
