As harmful algal blooms begin to happen with greater frequency, agencies are working to shape agricultural practices in ways that curtail blooms and preserve farms and fisheries. Here, new research will be presented on the effects of climate change on algae blooms in Lake Erie, which provides drinking water for 11 million people and supports a $1.7-billion tourism industry. Researchers will also discuss new tools in development to curb future blooms. Participants: Noel Aloysius, Postdoctoral Research Scientist, Department of Food, Agricultural and Biological Engineering and Department of Evolution, Ecology, and Organismal Biology, Aquatic Ecology Laboratory, The Ohio State University, Columbus, Ohio, U.S.A.; Hans W. Paerl, Kenan Professor, Marine and Environmental Sciences, Institute of Marine Sciences, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina, U.S.A.
