The meeting kicks off April 1 with presentations on several Sea Grant- and EPA-funded studies. IISG’s Tomas Hook, Sergiusz Czesny, director of the Lake Michigan Biological Station, and Bo Bunnell of the USGS Great Lakes Science Center will discuss the state of Lake Michigan fish populations, including the results of a three-year investigation of the differences in nearshore food webs across the lake. Harvey Bootsma, a researcher at the University of Wisconsin-Milwaukee, and NOAA’s Henry A. Vanderploeg will also be onsite to talk about recent findings on the diets of phytoplankton, algae, and other species at the bottom of the food chain. Additional presentations, orchestrated by IISG’s Paris Collingsworth and featuring IISG-funded scientist Cary Troy, will talk about research on the physical dynamics of the lake and steady flow of nutrients brought in by stormwater runoff—two important factors affecting food web structures. Paris will also introduce plans for upcoming monitoring and field activities in Lake Michigan as part of the Cooperative Science and Monitoring Initiative.

Work continues on unraveling the Lake Michigan food web
March 17th, 2014 by iisg_superadminIn the news: Targeted bacterium could be the solution to invasive mussels
March 6th, 2014 by iisg_superadmin“Now the mussels may have met their match: Daniel P. Molloy, an emeritus biologist at the New York State Museum in Albany and a self-described ‘Bronx boy who became fascinated by things living in water.’Inspired by Rachel Carson’s ‘Silent Spring’ in high school, Dr. Molloy, now 66, has long been a pioneer in the development of environmentally safe control agents to replace broad-spectrum chemical pesticides.
Leading a team at the museum’s Cambridge Field Research Laboratory in upstate New York, he discovered a bacterium, Pseudomonas fluorescens strain CL145A, that kills the mussels but appears to have little or no effect on other organisms.As a result, New York State has awarded a license to Marrone Bio Innovations, a company in Davis, Calif., to develop a commercial formulation of the bacterium. The product, Zequanox, has been undergoing tests for several years, with promising results. (Dr. Molloy has no financial ties to the company.)Zequanox killed more than 90 percent of the mussels in a test using tanks of water from Lake Carlos in Minnesota, said James A. Luoma, a research biologist with the United States Geological Survey in La Crosse, Wis. A control group of freshwater mussels, unionids from the Black River in Wisconsin, were unharmed.”
Lake Erie “dead zone” research includes work by IISG specialist
March 3rd, 2014 by iisg_superadmin“The report from the multi-institution EcoFore-Lake Erie project states that a 46 percent reduction in the amount, or load, of phosphorus pollution would be needed to shrink Lake Erie’s Central Basin hypoxic zone to a size last seen in the mid-1990s—a time that coincided with the recovery of several recreational and commercial fisheries in the lake’s west and central basins.Phosphorus is a nutrient used in crop fertilizers. Excess phosphorus washes off croplands during rainstorms and flows downstream in rivers that feed the Great Lakes. Once in the lakes, phosphorus can trigger algae blooms. When the algae die and sink to the lake bottom, oxygen-consuming bacteria feed on them and create hypoxic zones in the process. Many fish shun these oxygen-starved waters, which significantly reduce the amount of suitable habitat available to the fish.The study, accepted for publication in a forthcoming edition of the Journal of Great Lakes Research, calls for Central Basin phosphorus reductions considerably higher than other recent recommendations, including a proposal issued last year by the Ohio Lake Erie Phosphorus Task Force aimed at avoiding Western Basin toxic algae blooms. The new report is a synthesis of the major findings from the EcoFore-Lake Erie project, created in 2005 and supported by the U.S. National Oceanic and Atmospheric Administration’s Center for Sponsored Coastal Ocean Research.”
Knauss fellow Will Tyburczy continues on with science collaboration work at NOAA
February 28th, 2014 by iisg_superadminA Ph.D. candidate at University of Chicago, Will spent the bulk of the last year helping NOAA’s Regional Collaboration Network coordinate the work of NOAA’s five main offices—Weather Service, Fisheries Service, Satellite and Information Service, Ocean Service, and Oceanic and Atmospheric Research. The efforts of these offices often overlap on major issues like climate change, habitat conservation, and emergency response. It was Will’s job, along with the other network members, to find opportunities for collaboration and help NOAA make progress on these issues. He also served as a liaison between NOAA regional staff and organization leaders, ensuring that each group had the information and resources they need to effectively meet program goals.
Discovery Grants fund promising Great Lakes research projects
February 25th, 2014 by iisg_superadminSo, what are these projects exactly? We’re glad you asked. Discovery Grant Projects II shines a light on unexpected and emerging contaminants in stream water. Other featured projects examine the market for domestic seafood and give Hoosiers real-time access to fish consumption advisories. And another still paints a clearer picture of how Asian carp are changing the food web in the Illinois River.
Great Lakes hold great potential for curing diseases
January 22nd, 2014 by IISGThe IISG-funded study unearthed more than 600 strains of freshwater actinomycete bacteria, making it one of the largest “libraries” of its kind in the world. Murphy—with help from UIC researchers Scott Franzblau, Joanna Burdette, and Lijun Rong—is still testing whether these strains can be used to create new treatments for tuberculosis and other life-threatening diseases. But their initial results suggest that at least a handful of freshwater bacteria could lead to new cures.
Murphy and his team will spend the next few months scrutinizing chemical compounds from 10 actinomycete strains already showing disease-fighting potential and comparing them against known antibiotics, anti-virals, and anti-cancer agents. At the same time, they will keep working through their bacterial library hoping to find even more molecules with drug-like potency.
Knauss Fellows head to D.C. to find and begin their new positions
December 13th, 2013 by Irene MilesI selected a position at the National Science Foundation’s Division of Ocean Sciences. Part of my responsibilities will be to facilitate peer review and award decisions for proposals submitted to the Ocean Section, including the Coastal Science, Engineering and Education for Sustainability (Coastal SEES) program. I am really excited to be exposed to cutting-edge research and to see the grant review process first hand. I think that reading and participating in the review of the Coastal SEES proposals will be particularly enlightening due to their interdisciplinary nature.
In the news: Great Lakes microplastic pollution research recently published
November 4th, 2013 by Irene Miles“Take a dip in lakes Erie, Huron, or Superior and you will be swimming in more than just water. According to a recently published study, these lakes contain an unexpectedly large amount of floating plastic debris. Even more surprising, much of what the researchers found were microplastic fragments and pellets like the kind used in toothpastes and facial and body scrubs. At less than one millimeter, these tiny pieces of plastic are too small to be filtered out at wastewater treatment facilities before the water is released into the lakes.
Researchers from 5 Gyres Institute and State University of New York (SUNY) Fredonia made the discovery in 2012 after collecting a total of 21 samples from the lakes. They found plastics in all but one sample. Of the three lakes, Lake Erie had the highest concentrations of plastics, roughly 90 percent of the total amount measured. The authors speculate that the high concentrations may be the result of currents carrying the plastics from the cities of Detroit, Cleveland, and Erie. Back in the lab, further inspection revealed that along with the microplastics, eight of the samples contained coal ash and coal fly ash (produced by coal-burning power plants).”
Nearshore buoy wraps up another successful season of Lake Michigan data collection
October 31st, 2013 by Irene MilesBuoy-watchers will have more to look forward to in 2014, as this winter the buoy will be getting an upgrade. Thanks in part to a grant from the Indiana Department of Natural Resources Lake Michigan Coastal Program awarded to IISG’s Tomas Hӧӧk, the buoy will broadcast real-time temperatures at different depths during the 2014 season and beyond. The buoy has always collected surface water temperature, but now it will also collect temperatures approximately every three feet from the surface to the bottom of the lake.
“We are very excited to install this chain of temperature loggers”, said Carolyn Foley, IISG assistant research coordinator who will help implement the new chain. “A number of groups told us they would use this information, from kayakers wanting to know if it’s warm enough to go for a paddle to anglers wanting to know where the best fishing will be.”
We would like to hear from anyone who uses the buoy data, particularly anglers, paddlers, and others who use southern Lake Michigan for recreation, as well as educators interested in using buoy data in their classrooms. If you 1) are an educator in grades 8-12 interested in participating in a workshop to acquire data sets for teaching and to develop lesson plans with buoy data, 2) have feedback related to improving the buoy website, and/or 3) would like to suggest an outdoor show for us to attend, please send us an email (iisg@purdue.edu) with “Buoy feedback” in the subject line. We expect to redeploy buoy in mid-May 2014.
Special thanks to the staff of the Indiana DNR Michigan City Field Office for their help deploying and retrieving the buoy.
