“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.”

Lake Erie “dead zone” research includes work by IISG specialist
March 3rd, 2014 by iisg_superadminIn the news: A “stirring” solution to algae problems?
February 6th, 2014 by iisg_superadmin“The N.C. General Assembly authorized a $1.44 million plan to put 36 floating water circulators into the lake. It’s a hefty price tag, but is actually one of the drivers for the experiment. If it works, the savings could be huge as costs for implementing the EPA rules are estimated at $1 to $2 billion.Representatives from Medora Corporation, the company that will supply the mixers, say that the mixing process may confuse the algae, making them think they’re at different depths in the water. It could make them more vulnerable to viruses. The reps also say the mixers will work, claiming a 90 to 95 percent success rate in other lakes.”

The Shipboard Science Immersion educators worked together to simulate sonar mapping and uncover the secrets of a mystery seabed, just like real underwater archaeologists!
This hands-on lesson mirrors the work of Dr. Ashley Lemke from University of Wisconsin Milwaukee who studies paleo landscapes below Lake Michigan by collecting sonar data from lakebeds. Experiences like these can be shared with youth to spark curiosity and connect them to real-world science in action.
#LakeMichigan #GreatLakes

15 educators from 7 Great Lakes states have boarded the R/V Lake Guardian for a week of science on Lake Michigan!
Day one was all about meeting fellow educators and the science team from the @epa_greatlakes, @uwmilwaukee, and @purduefnr, and getting shipboard safety training.
This hands-on program, supported by the Great Lakes Restoration Initiative, helps bring Great Lakes science into classrooms and builds educator-scientist partnerships.
Follow along as we explore water quality, food webs, and even underwater archaeology!
