IISG’s science writer reports in from IAGLR 2013 – Day 1
June 3rd, 2013 by Irene Miles“There is more food for Asian carp in Lake Michigan than people thought. In a morning filled with new insights into these invasive species’ biology and potential impact in the Great Lakes, this fact rang the loudest for me. I have read some of the research in recent years speculating that Asian carp could not survive in much of the Great Lakes, which have less of the phytoplankton and zooplankton than the ravenous eaters need. What my fellow session attendees and I learned this morning, though, is that the plankton population has been underestimated. There are more–much more–of the smallest species living in the nearshore waters of Lake Michigan than previously believed.
Illinois the latest state to start Clean Marina program
May 31st, 2013 by Irene MilesThis month Illinois joined a number of other Great Lakes states by instituting a Clean Marina program. Designed to reduce and prevent pollution, the program provides best management practices for marina operators to help protect waterways and the environment. Illinois-Indiana Sea Grant created the Clean Marina guidebook (PDF) in collaboration with Illinois DNR to offer a comprehensive manual for marina operators with important environmental protection and best practice information.
From our latest edition of The Helm:
“Nearly a quarter of Illinois’ 70 marinas sit along Lake Michigan, making the Illinois shoreline the most active in the Great Lakes region. Millions of people in the Chicago area rely on that same stretch of Lake Michigan for drinking water. Here, even small levels of pollution from marinas can have a significant impact on the lake and the communities that rely on it.
At the heart of the Clean Marina Program are best management practices that make marina operations and boater activities more efficient and environmentally friendly. Practices cover a range of topics, from marina construction to vessel maintenance, and most are easy and affordable. Some recommendations, such as how to protect nearby habitats during construction, will help new or expanding marinas develop greener sites from the beginning. And others will help marina personnel educate boaters on what they can do to protect and improve the state’s water quality. Marinas that adopt the practices will be certified as a clean marina by the Illinois Department of Natural Resources (IDNR) Coastal Management Program.”

In the news: Teachers identify the good and the still needed in Great Lakes literacy education
May 28th, 2013 by Irene MilesDozens of Michigan teachers were some of the attendees at the 2013 Great Lakes Conference at Michigan State University back in March, and one of the most important topics of discussion was the current and future need for improving Great Lakes literacy.
From the MSU office of extension:
“At the luncheon, educators learned about upcoming professional development opportunities relating to the Great Lakes, and shared their best practices in Great Lakes education, as well as their priority needs relating to advancing Great Lakes literacy in the classroom.
So with the goal of advancing Great Lakes literacy in mind, what were some of their best practices and needs that emerged from the teacher discussion? The best practices clustered around five themes: 1) curriculum, 2) place-based education, 3) data in the classroom, 4) hands-on learning, and 5) cross-curriculum lessons…”

Food web complexity one of several panel topics at upcoming 2013 IAGLR conference
May 22nd, 2013 by Irene MilesPresentations will discuss a range of issues that help determine just what eats what in the lake. Several will focus on what happens to the diet of native species when invaders like quagga mussels, round goby, spiny water flea deplete food resources. Others will introduce how shifts in phosphorus and other nutrient levels may be behind recent changes at the bottom of the food web and compare the eating habits of forage fish over the last two decades.
The session is a part of ongoing regional efforts to improve understanding of the complicated relationships between the many different microbes, plants, and animals that call Lake Michigan home. Since 2010, IISG and other partners in the Great Lakes Regional Research Information Network have funded several studies on the links that form the food web.
In addition to serving as co-chair, Tomas will join researchers from across the Great Lakes to present the findings of three studies slated for the session. For a description of these and other presentations, visit the session schedule and click on the presentation titles.
The International Association for Great Lakes Research’s (IAGLR) 56th Annual Conference on Great Lakes Research is sponsored by IISG and Purdue University. To view the entire program, visit the conference website.
In the news: Scotts leads the way in removing phosphorous from fertilizers
May 16th, 2013 by Irene MilesPhosphorous is a nutrient that has been linked to significant runoff problems and excessive algal growth in water bodies including the Great Lakes. Recently, Scotts Miracle-Gro announced that they will be removing phosphorous from their line of lawn fertilizers to address the issue and help reduce nutrient pollution problems.
From The Columbus Dispatch:
“The Marysville maker of lawn-and-garden products sees the move as a milestone for its industry, which it says is partly responsible for the phosphorus runoff that feeds one of the nation’s most costly and challenging environmental problems — nutrient pollution.
‘As consumers feed their lawns this spring, they should know they can get great results from our products while also protecting and preserving our water resources,’ said Jim Lyski, Scotts’ chief marketing officer, in a written statement.
Harmful algae blooms in coastal areas of the United States are estimated to have a yearly negative economic cost of at least $82 million, mostly because of their effects on public health and commercial fisheries, according to a 2006 report by the National Centers for Coastal Ocean Science.’
