IISG’s Caitie McCoy attended the Seventh International Conference on Remediation of Contaminated Sediments last week to present her community outreach work with the Great Lakes Legacy Act (GLLA). The conference traditionally features environmental scientists and engineers, but that is changing. “We are starting to see more attention paid to community engagement at these types of conferences,” Caitie tells us. “Technical project managers realize that projects are easier to implement when the community understands and supports the work, and so they’re eager to learn from professionals who specialize in community engagement and stakeholder involvement.”
Caitie presented a poster on her educational program in northwest Indiana, which taught students about the GLLA sediment cleanup at Roxana Marsh on the Grand Calumet River. Instead of presenting a typical scientific poster full of text and graphs, Caitie displayed a mural that her fourth grade students made to represent the Roxana Marsh ecosystem.
“Some of my colleagues were a bit skeptical about me presenting a fourth grade mural to a bunch of technical folks, but I’m not afraid to shake things up,” Caitie said. “I wanted to use something eye-catching that would draw people’s attention toward my poster.” And it worked. Caitie was visited non-stop during the session and talked to more than 100 conference attendees about her program. When asked if she thought her poster made an impact, Caitie replied, “I would never have dreamed that someday engineers would be asking me how to replicate my educational program at their sites, so I take that as a big success.”
Caitie will expand her programming throughout the Grand Calumet River community in 2013, as the Legacy program begins another phase of dredging this summer.
Approximately 300,000 cubic yards of sediment (equivalent to 15,000 dump trucks full) contaminated with PCBs and PAHs were removed from the river between August 2012 and early January 2013. As a result, river-goers will enjoy a deeper river with better navigation and access, and a cleaner habitat for fish and wildlife to thrive. Low temperatures and more characteristic winter weather have turned parts of Lake Michigan into a frozen lunar landscape – perfect for some chilly but scenic photography.
From Michigan Live:
Last year Lake Michigan was nearly ice-free. But cold weather in 2013 has brought a return to the ice formations typical to West Michigan’s winter shoreline.”

Today’s blog post features a fun bit of physics from Wired.com’s science blog.
Writer Rhett Allain, professor at Southeastern Louisiana University, received an interesting question over Twitter – “What would happen if everyone on the planet jumped in the water?”
“Let’s give a slightly refined version of the question.
‘If everyone on Earth went for a swim at the same time in Lake Michigan, how high would the water level rise?’
I have two primary assumptions to start with. First, I will assume that during this time the volume of water in Lake Michigan will be constant. So if the people make the water level rise, the water level will indeed rise instead of pushing water into the other Great Lakes. Second, I will assume that all of the humans in the lake are floating. If they aren’t ‘swimming’ or touching the bottom, then it will be easier to calculate the rise in the water level.”

The frigid waters of Lake Michigan during a Midwestern winter may not seem very inviting to us, but some species spend a great deal of time there.
From Phys.org:
“On Nov. 2, 2010, Mueller documented 25,555 long-tailed ducks in Lake Michigan.And on Jan. 20, 2011, 9,311 red-breasted mergansers were tallied.The data comes from the Lake Michigan Offshore Waterfowl and Waterbird Survey, a project initiated in 2009 by Mueller and Noel Cutright, both of the Western Great Lakes Bird and Bat Observatory in Belgium.
The work is designed to increase the understanding of key offshore Lake Michigan bird habitats, many of which have been lightly studied.”

IISG’s Aquaculture Marketing Specialist Kwamena Quagrainie, who also directs the aquaculture economics and marketing program at Purdue University, was recently promoted to the position of Clinical Engagement Assistant Professor in Agricultural Economics. Dr. Quagrainie has been involved for many years in aquaculture marketing and outreach, helping numerous aquaculture operations get started or expand their business throughout the Midwest. He has also been involved in international efforts to promote and foster aquaculture operations throughout several African nations.
Illinois-Indiana Sea Grant is celebrating its 30th anniversary, and 30 years of working to protect and preserve the beauty and resources of Lake Michigan. But what is some of that work? What are some of the things that IISG does to understand, restore, and celebrate our Great Lakes resources?
We’re glad you asked. Our latest publication features 30 milestone achievements selected from the last three decades, all detailing ways that we support our mission to improve and protect the southern Lake Michigan area.
Visit the link to download your own copy of our 30 milestones, or contact us if you would like print copies to share with. And here’s to the next 30 years of keeping our Great Lakes great!
SeaPerch, a program that brings underwater robotics to classrooms and demonstrates how they can be used for educational purposes, recently held a workshop at the University of Illinois Hydrosystems Laboratory. IISG’s Robin Goettel and Terri Hallesy were among the presenters and they shared a number of educational materials that teachers could combine with their classes’ underwater robots.
Over lunch, participants interacted with U of I graduate students in engineering to discuss research topics and applications for their in-class lessons. Robin and Terri shared educational resources including two COSEE Great Lakes curriculum collections, Greatest of the Great Lakes: A Medley of Model Lessons, and a Fresh and Salt activity, “I, Robot, Can Do That!” During the afternoon session, a live demonstration of the SeaPerch robot was conducted and teachers had an opportunity to operate the SeaPerch robots in the large-scale laboratory facilities.
Meet IISG grad student scholar, Dohyung Bang! Dohyung is a PhD candidate in the White Lodging-J.W. Marriott, Jr. School of Hospitality and Tourism Management (@purduehtmlife) program at Purdue University. He is studying how complex tourism systems shape societal and economic outcomes. His project, funded by IISG, examines the impact of the home-sharing economy on housing market dynamics in the Lake Michigan area.
