“Höök’s research focuses on fish and fisheries ecology in the Great Lakes. Fish communities and populations—species numbers and their traits—change a great deal from year to year, he explains. Höök studies past, current and projected future conditions to examine the factors that lead to these changes over time and across habitats. He uses a variety of research methods, including lab experiments on how fish respond to different situations, field studies and computer modeling.”

Purdue turns the spotlight on one of IISG’s own
October 30th, 2013 by Irene MilesIntern Allison spends some of her summer internship on-board a research vessel
October 22nd, 2013 by Irene Miles
“As an indecisive, undeclared sophomore I enrolled in a course titled Environmental Sustainability. Though I registered with low expectations, I found myself completely captivated by the readings and discussions we had in class. By the end of the semester I knew environmental sustainability was a passion I wanted to pursue, and I declared a major in Earth, Society, and the Environment. I also added a Geography and GIS Major and Business Minor along the way. Studying and working in these fields has afforded me the opportunity to engage in a wide range of academic and extracurricular experiences that have truly shaped my outlook on the world and secured my commitment to responsibly addressing environmental issues.
My internship with the Illinois-Indiana Sea Grant this summer has been the most rewarding experience of my collegiate career thus far. As the Great Lakes Education Intern I worked under the leadership of my mentor Kristin TePas to develop a website for the U.S. EPA research vessel Lake Guardian that effectively communicates the ship’s research and educational activities to the general public. The Lake Guardian is a unique and extremely valuable resource that has facilitated Great Lakes research for over 25 years, which in turn promotes better understanding and awareness of environmental issues affecting the lakes.
Kristin and I, through the creation of a user friendly Lake Guardian website, hope to expose teachers, students, and the general public to current Great Lakes research projects and inspire communication between scientists and their communities. By interviewing our target audience we determined what people wanted to see on the website and then developed some of the items they requested, including a ship specifications chart, science equipment videos, an ‘Ask a Scientist’ form, FAQ page, Science and Marine Career videos, as well as a YouTube channel and Flickr gallery to give a sense of life and work on the ship. The overarching goal is for the Lake Guardian site to be a fun and engaging way to compel people to be invested in the health and vitality of the Great Lakes.
My experiences this summer have opened my eyes to the importance of protecting the Great Lakes, which had not previously been in the forefront of my environmental concerns. Even growing up in Chicago I took Lake Michigan for granted because I did not understand how fragile the Great Lakes ecosystem truly is, or how critical the Lakes are to people’s livelihoods. Increasing awareness is vital to conserving the Great Lakes, and my position with Illinois-Indiana Sea Grant this summer gave me great exposure to environmental outreach. I have thoroughly enjoyed my work, especially all the valuable input I received from an assortment of teachers, scientists, Lake Guardian crew, and Sea Grant staff. This internship has been an excellent growing experience for me. I have vastly improved my communication, planning, and organizing skills as well as enhanced my understanding of the Great Lakes.”
Allison is one of four interns who worked with IISG this summer.
New IISG research will inform natural resource decisions

SeaPerch contest winners get their robots up and running
October 14th, 2013 by Irene MilesLast month, we announced that six teachers from the Champaign-Urbana area had won tool kits for constructing simple, remotely operated underwater robots with their students. With the help of online lesson plans, the winning teachers will use the SeaPerch robots to teach their students about topics including buoyancy, propulsion, circuitry, and biological sampling.
Along with the kits, teachers got an opportunity to learn construction techniques and practice using the equipment during one of two SeaPerch Build Sessions held in October. During the sessions, Blake Landry, coordinator of the University of Illinois SeaPerch Program, took teachers step-by-step through the build process.
The winning teachers have big plans for their robots. Some will use them to introduce their younger students to basic engineering concepts for the first time. In other classrooms, the robots will provide an opportunity for students to test their knowledge of things like simple circuits. Some teachers are even considering partnering up to start an after-school club that will compete in the national SeaPerch Challenge. With these six teachers now using SeaPerch, there is also a possibility that they may launch a regional SeaPerch Challenge.
The SeaPerch giveaway contest was funded by Illinois-Indiana Sea Grant to help teachers in the Great Lakes region integrate science education with engineering and math.
Visit the SeaPerch homepage to learn more about the tool kits and the SeaPerch program.

Purdue’s Department of Forestry and Natural Resources celebrates 100 years
September 25th, 2013 by Irene MilesThe Purdue University Department of Forestry and Natural Resources (FNR) celebrated their centennial anniversary from September 20-22, and included back-to-class sessions, tours of FNR buildings including the aquaculture research laboratory, and a Saturday evening banquet. More than 250 guests, including many FNR alumni, joined in the celebrations.
FNR has spent the past 100 years training professional foresters, fishery and wildlife scientists, and natural resource managers who help to preserve and protect environmental resources throughout the country.
Illinois-Indiana Sea Grant (IISG) has proudly partnered with FNR for more than 30 years. Brian Miller, IISG Program Director, said, “The Illinois-Indiana Sea Grant College Program highly values our 30 year partnership between NOAA, Purdue University, and the University of Illinois. This type of bi-state partnership only works in one other Sea Grant college in the country, and only works because of the mission-driven spirit of collaboration that exists on both of our campuses. The innovation, dedication and creativity of FNR have helped make the Illinois-Indiana Sea grant college program successful and enabled us to achieve positive impacts for local communities and the Great Lakes ecosystem.”
Recent IISG work was showcased during a welcome reception Friday night, and IISG staff assisted in organizing several of the celebration events throughout the weekend. Numerous current IISG staff members have worked closely with FNR, including Miller, Angela Archer, Carolyn Foley, Tomas Hӧӧk, Kwamena Quagrainie, and Kara Salazar, and the partnership continues to offer a crucial link in protecting coastal areas and waterways.

In the news: Study shows bacteria developing resistance to antibacterial compounds
September 20th, 2013 by Irene MilesRecent research in the Chicago area shows that bacteria are developing a resistance to a common antibacterial chemical used in many household and personal care products.
From The Cary Institute:
“Invented for surgeons in the 1960s, triclosan slows or stops the growth of bacteria, fungi, and mildew. Currently, around half of liquid soaps contain the chemical, as well as toothpastes, deodorants, cosmetics, liquid cleansers, and detergents. Triclosan enters streams and rivers through domestic wastewater, leaky sewer infrastructure, and sewer overflows, with residues now common throughout the United States.Emma Rosi-Marshall, one of the paper’s authors and an aquatic ecologist at the Cary Institute of Ecosystem Studies in Millbrook, New York explains: ‘The bacterial resistance caused by triclosan has real environmental consequences. Not only does it disrupt aquatic life by changing native bacterial communities, but it’s linked to the rise of resistant bacteria that could diminish the usefulness of important antibiotics.'”
In the news: Small number of Asian carp could establish a large Great Lakes population
September 16th, 2013 by Irene MilesRecent research indicates that even a handful of Asian carp, between just ten and twenty fish, could establish an ecologically damaging population in the Great Lakes.
From ScienceDaily.com:
“Published this week in the Biological Invasions journal, research from Professor Kim Cuddington of the Faculty of Science at Waterloo indicates that the probability of Asian carp establishment soars with the introduction of 20 fish into the Great Lakes, under some conditions…‘This species will have a huge impact on the food web,’ says Professor Cuddington. ‘Not only is it a fast-growing fish physically, but the population itself grows very quickly. A female can lay well over a million eggs a year, and with no known predators present in the Great Lakes, the Asian carp could dominate the waters and impact fisheries.’…
Individual fish have already been caught in two of the Great Lakes. The probability of Asian carp establishment changes dramatically if only 10 of the creatures are introduced. With 10 fish, the probability of a population of Asian carp is only 50 per cent, but with 20 fish, it jumps to 75 per cent, under some conditions.”
Aquaculture industry continues to grow in the Midwest
September 12th, 2013 by Irene MilesIISG staff will have the opportunity to see aquaculture in action next week while touring the Bell Aquaculture facility in Albany, IN. IISG’s Kwamena Quagrainie has been studying and providing expert advice to aquaculture operations in the Midwest and worldwide for many years, and will be giving the staff more information on how the facility provides millions of pounds of sustainably grown fish to the market each year.
Aquaculture has been a growing food field in the state of Indiana, and a recent feasibility study funded in part by IISG (available online soon at our research projects page) shows that it may have significant potential in Illinois as well.
Additionally, Purdue University produced this great video about aquaponics, which is an extension of aquaculture where fish and plants are raised sustainably and simultaneously in a mutually beneficial system.

In the news: Following the currents to track movement through Lake Michigan
September 11th, 2013 by Irene Miles“The Great Lakes lack the predictable regularity of tides; a combination of factors including winds, temperature and current depth influence currents. Combined, these factors cause a complex, spiraling water flow, producing a type of interior (rather than surface) waves called inertial waves.The researchers hypothesize that the inertial waves are the primary mechanism governing the movement and dispersion of particles. ‘You can get currents as strong as a half-meter per second in the middle of Lake Michigan,’ Cary Troy of Purdue’s School of Civil Engineering said prior to the study. ‘The effect is strongest in the middle of each of the Great Lakes, so that’s why we are doing the research there.’‘The goal is to do dye-release experiments and to track the dye patch over time to see where it diffuses and where it moves and to relate that to the information we have about the lake currents and waves,’ Troy said. ‘One obvious application is for something like an oil spill or any sort of contaminant spill in the Great Lakes. If you have a spill, you need to predict where it’s going to go and how quickly it’s going to dissipate.'”
