A new environmental sensing buoy will be placed north of Chicago this summer, making it easier than ever for Illinois boaters and beach-goers to spend a fun, safe day on the water.
Like its counterpart in Michigan City, IN, the nearshore buoy will relay information on wave height and direction, wind speed, and air and surface water temperatures in near real time. A webcam will also make it possible to watch changing lake conditions first-hand.
This is the newest in a string of nearshore buoys along the Lake Michigan shoreline. In addition to allowing people track waves and temperatures, the data they collect will help officials warn beachgoers when contamination levels may make swimming unsafe. Researchers also rely on the real-time information to manage fisheries, monitor lake currents, and improve hazardous weather predictions.
The Illinois buoy, jointly operated by IISG and LimnoTech, is expected to go online in May. The project is funded by the Great Lakes Observing System through a grant from NOAA Coastal Storms.

October brought good news for the residents of Blue Island, IL when the state announced a $1.1 million investment to expand and improve the city’s stormwater management efforts. The bulk of the grant money will go to green infrastructure projects along one of the city’s major roadways, which will reduce flooding, improve local water quality, and beautify the community. Remaining dollars will be used to restore an 11-acre wetland in a northeast detention pond.
The new projects are the latest in a series of local, state, and non-profit programs tackling stormwater runoff in this suburban community. In 2012, IISG teamed up with the Metropolitan Agency for Planning, Illinois EPA, and many others to combat local flooding with native plants, rain gardens, and rain barrels. That year, the Blue Island, Blue Water initiative helped distribute 125 rain barrels to residents and institutions in one of the city’s flood-prone neighborhoods. And roughly 1,000 native plants and trees were planted over the course of the project.
Sea Grant educators and specialists also conducted numerous teacher and homeowner workshops to strengthen community awareness of green infrastructure practices and other strategies for managing and reducing stormwater runoff.
It’s early success led the Illinois Department of Natural Resources to name Blue Island, Blue Water a Millennium Reserve model project in 2012. Lessons learned during the project have also helped inform the new Calumet Stormwater Collaborative, charged with coordinating the region’s stormwater and green infrastructure efforts to maximize the impact of individual city and agency projects.
The collaborative is led by the Metropolitan Agency for Planning and brings together numerous groups interested in stormwater issues, including the Metropolitan Water Reclamation District, the South Suburban Mayors and Managers Association, and IISG.

Several IISG staff members were in Grand Rapids, MI earlier this month to share some of our education resources and curricula during the Great Lakes Place-based Education Conference. For Allison Neubauer, the experience had an unexpected twist.
Stewardship and place-based education are nothing new to us educators at Illinois-Indiana Sea Grant. In fact, the IISG education team has been leading efforts in these initiatives throughout southern Lake Michigan communities for years. For this reason, going into the conference, I thought it was a great opportunity for us to share our models of stewardship and place-based education. I didn’t plan on gaining much insight into how and why these objectives were critical. Boy, was I wrong.
IISG undoubtedly has an arsenal of exemplary stewardship models, and a jam-packed room of eager educators at our Friday afternoon session was an indication of their desire to hear how we’ve extended learning beyond classrooms and into communities.
But as much as I enjoyed sharing our examples of student stewardship as a means of combatting invasive species, promoting proper disposal of unwanted medication, and teaching about benefits and risks of fish consumption, the best part of the conference was actually hearing others share their stories.
The opening keynote address by Kim Rowland, a middle school science teacher, detailed how her students have been able to use their surrounding environment in Grand Rapids as a resource for exploration and learning. What was most captivating and exciting to hear was how this time spent investigating the outdoors was a way to reach students that are not typically high academic achievers. Kim told us about a particular student who was always getting in trouble—not wanting to come to school, and certainly not excited about learning. Though she had not anticipated this, venturing out to the stream on school property transformed him into the most enthusiastic student of the group. In fact, this student was now so interested in collecting samples that he waded even further into the stream, thus giving Kim a very fitting title for her presentation: “Getting Your Feet Wet and Allowing Water to Flood Your Boots.”
This was a great way to kick-off the conference. It really impressed upon me that place-based education should not be considered a luxury, or something that only all-star teachers are doing. Every student—from urban to rural, high achieving to special needs—must be exposed to learning outside the classroom. School should not take place in isolation, between the same four walls everyday. There is immense value in connecting students with their communities and surrounding environments as a means to enhance learning and civic understanding.

Eliana Brown recently joined the Illinois Water Resources Center as an outreach specialist. Prior to starting at IWRC, she worked at University of Illinois at Urbana-Champaign Facilities & Services as the MS4 coordinator and at Illinois EPA as a field engineer. Eliana has a M.S. in environmental engineering and a B.S. in general engineering and marketing from the University of Illinois.
The following is a contributing post from Eliana, who has a passion for rain gardens and green infrastructure:
When you were a university student, did you ever reimagine your campus landscape? Students at the University of Illinois did exactly that as an assignment for Landscape Architecture (LA) 452, Native Plants and Design.
The U of I campus has 84 miles of storm sewer, most of which drain rainwater directly to Boneyard Creek. The LA 452 students designed landscapes with elements that capture water and allow it to soak in on-site to reduce loads to the existing storm sewer and creek. These elements (called green infrastructure) include rain gardens, swales, and green roofs. The Environmental Protection Agency (EPA) sees green infrastructure as a way to create sustainable, resilient communities that improve water quality.
EPA has a competition called the Campus RainWorks Challenge that invites “student teams to design an innovative green infrastructure project for their campus showing how managing stormwater at its source can benefit the campus community and the environment.”
According to Jason Berner, EPA environmental protection specialist, who has been involved with administering the competition, it is a great way for students to see how green infrastructure is related to the larger campus master plan. “It moves us beyond single pilot projects, but at the same time, blends both small and large scale thinking,” he explained.
LA 452 instructor Tawab Hlimi is leading the U of I Campus RainWorks entry. Students in his class helped brainstorm ideas for the entry. One of those ideas is pictured. Student Jiwon
Kim reimagined the grounds at the National Soybean Research Building (which happens to house Illinois-Indiana Sea Grant and the Illinois Water Resources Center). Native plant rain gardens intercept stormwater from the building roof and parking lot. During large storms, the design takes advantage of existing storm sewers by overflowing excess water to them.
Like many cities and universities, the U of I began installing storm sewers more than 100 years ago. Storm sewers benefit cities by draining flooded areas. However, they can overload receiving streams and cause unintended damage. Adding green infrastructure elements to the existing infrastructure helps ensure a healthier ecosystem on-site and downstream.
Per Hlimi, “Through a campus wide application of rain gardens, students hybridized native plantings with a superficial stormwater management strategy to meet multiple objectives: accommodating the ‘first flush’ of frequent storm events through detention, infiltration, and biofiltration, reducing the load on existing subsurface infrastructure, improving the water quality entering into the Boneyard Creek, creating habitat for pollinators, and rendering the campus landscape as living laboratory.”
Perhaps one day in the not too distant future, students won’t have to imagine green infrastructure on campus. They’ll see it.

Former intern Jacob Wood received an award earlier this month for a poster he presented during Purdue University’s GIS Day, an annual event dedicated to geospatial research and geographic information systems (GIS).
“The poster detailed my work over the summer with IISG on mapping Lake Michigan catch data. Jarrod Doucette and myself have been working creating a web app for the IISG website to visualize two decades of recorded fish catch data from the Indiana, Michigan, Illinois, and Wisconsin Departments of Natural Resources. I thought presenting the poster at Purdue’s GIS Day would be a great way to show the work that I accomplished for IISG over the summer.”

Microbeads have attracted a lot of public and political attention in the Great Lakes region since Sam Mason and her lab first discovered the tiny beads in staggering numbers in lakes Huron, Superior, and Erie in 2012. Since then, sampling excursions on the remaining lakes—conducted with help from Illinois-Indiana Sea Grant and 5 Gyres—have turned up similar findings.
In many ways, the results of these studies raise more questions than they ask. One of the most important, though, is “What effect do microbeads and other plastic pollutants have on Great Lakes food webs and ecosystems?” Research into this question has only just begun, but years of studies in the oceans provide some insight. Some of these latest findings come from our friends at South Carolina Sea Grant.
From Coastal Heritage:
John Weinstein is studying how grass shrimp (Palaemonetes pugio) respond to a diet of plastic beads. A crustacean about the size of half of a shelled peanut, a grass shrimp consumes microalgae that grow on plant detritus—especially decomposing saltmarsh stems called “wrack”—along estuaries and coasts, but it’s also a predator on a wide variety of small animals.
Because of its abundance, sensitivity, and ecological importance in southeastern U.S. estuaries, the grass shrimp is often used to study the effects of pollution in the field and laboratory.
In Weinstein’s lab, Austin Gray, a graduate student in biology at The Citadel, has been feeding grass shrimp two types of beads: one a bright green and the other one translucent.
The green beads are polyethylene, the type of plastic used in plastic bags, bottles, plastic wrap and other films for food preservation, and many other products. Polyethylene is the most common type of plastic found in marine debris around the world.
The translucent beads are polypropylene, a type of plastic used in bottle caps, candy- or chip-wrappers, and food containers. Polypropylene is the second most common type of plastic found in marine debris.
In a lab dish, Austin Gray deposits translucent 75-micron beads. But a visitor looks in the dish and can’t find a single bead. Under the dissecting microscope, though, dozens of tiny spheres suddenly appear. To put it in perspective, an item at about 40 microns is the width of two spooning human hairs.
Gray fed 16 grass shrimp a diet of brine shrimp mixed in with plastic beads. Each grass shrimp was isolated in water that was changed every other day. Eight animals were fed polyethylene beads and eight were fed polypropylene beads. After six days, all of the 16 shrimp were dead.
Dissecting the animals, Gray found plastic beads in their guts and gills. One individual had 10 tiny beads in its gut and 16 in its gills.
The gut blockages, though, were deadlier. The grass shrimp could still take in water through their partly blocked gills. But they stopped eating with clogged guts—or couldn’t eat—and died.
“In my mind,” says Weinstein, “it’s consistent with starvation. The more particles in guts, the more quickly the grass shrimp die.
Concern about results like these has led Illinois to become the first state to ban the sale of microbeads in personal care products. The law, passed in June, is slated to take full effect in 2019. Similar legislation has also been considered in New York and California.

It’s been two years since our first edition of UpClose, and we decided to celebrate the occasion by taking a behind-the-scenes look at the study that launched an era of scientific and public interest in pharmaceuticals and other emerging contaminants.
And to top it off, we’ve given the award-winning interview series a fresh new look.
Dana Kolpin, a research hydrologist and head of the U.S. Geological Survey Emerging Contaminants Project, played a key role in the first-ever nationwide survey of emerging contaminants. The study found pharmaceuticals, detergents, hormones, and other chemicals in streams across the country. When the results were published in the journal Environmental Science & Technology in 2002, they sparked a of flurry of media and research attention. To this day, in fact, it is still the most cited study in the journal’s history.
In the eighth issue of UpClose, Kolpin looks back on the challenges of designing and conducting a national study—particularly one in search of everyday chemicals like caffeine—and the cutting-edge methods scientists created to analyze the results. He also talks about the gaps in understanding that remain after more than a decade of investigating these contaminants and gives a sneak-peak at USGS’s latest projects.

If you’re a regular visitor to Great Lakes beaches, you likely noticed that this year’s swim season was chillier than normal. Cold enough, in fact, that many chose to skip swimming in favor of other beach activities. And according to officials at the National Weather Service, this may explain the unusually low number of current-related fatalities and rescues this year.
From Michigan Sea Grant:
There were 6 fatalities and 12 rescues related to currents on the Great Lakes, which is below the 12-year average of 12 fatalities and 25 rescues per year.
As is typical, the majority of the 2014 incidents occurred along Lake Michigan. On average from 2002-2014, Lake Michigan had 25 incidents per year, while Lake Erie had 5 incidents per year, Lake Superior had 3 incidents and Huron and Ontario average 1 to 1.5 per year, respectively.
The data for 2014 has now been updated in the Great Lakes Current Incident Database, available at DangerousCurrents.org. The database was developed and is maintained by Michigan Sea Grant and National Weather Service (NWS). Megan Dodson, a NWS meteorologist, gathers the statistics for the database and provides yearly swim season assessments of conditions related to currents.
Dodson noted the cool weather influenced not just the below-average number of incidents, but where they happened too.
“A majority of the current-related incidents in 2014 occurred near river mouths, which is unusual when compared with past years,” she said. “The cooler air and water temperatures may have driven beachgoers to swim near river mouths and other outlets, where the water is much warmer. However, there are currents present that can be strong and vary depending on the flow of the outlet and the waves at the beach. While these currents are most dangerous during times of high waves, they can still be strong despite calmer lake conditions — as we saw during the 2014 swim season.” Read more
Swim season may be over, but it is never too early to start planning for next year. To stay safe in the water, be sure to:
- Steer clear of the pier — Nearly 60 percent of fatalities and rescues in the Great Lakes database occurred near breakwaters and piers. Structural currents are nearly always present near these barriers, even when waves are low. Breaking waves can also bounce off the structure, making swimming nearly impossible.
- Stay dry when waves are high — Nearly 85 percent of fatalities and rescues in the Great Lakes database happened when waves are 3-5 feet or greater. Unlike in the oceans, Great Lakes waves crash against the shoreline in rapid succession, making it difficult to swim. Additionally, strong rip currents are more likely when waves are above 3 feet. The combination of quickly approaching waves and strong currents create extremely dangerous conditions for swimmers.
- Don’t swim in the outlet — Water flowing from a river mouth or other outlet can push swimmers out into the lake. Nearly 40 percent of the 2014 incidents were outlet-current related.

In Alaska’s Kachemak Bay Research Reserve, invasive species prevention is taking on a new look. To prevent the spread of the invasive invertebrates while a local harbor undergoes renovations, officials have adopted the Be a Hero – Transport Zero logo and slightly modified the message to encourage those involved in the reconstruction to follow a few easy before moving all docks and other infrastructure.
Closer to home, the outreach campaign developed by Illinois-Indiana Sea Grant and the Illinois Department of Natural Resources is also expanding to include hunting, hiking, and other terrestrial pathways. Posters asking customers to “join the fight” can be found in outdoor supply shops in several Illinois cities, including Springfield. The message also made an appearance at this year’s state fair in August.
When it launched last year, Be a Hero – Transport Zero became the primary invasive species prevention message in Illinois. It’s simple call for boaters, anglers, and other recreational water users to “remove, drain, dry” before leaving a waterbody has been featured in magazines, broadcast on radio and television, and wrapped into outreach programs like Clean Boats Crew.
