Lake Erie CSMI:Assessment of Nutrient/Eutrophication Dynamics in Western Lake Erie
Project Description • Nutrient loading to the western basin of Lake Erie has been recognized as a pivotal component in the re-occurrence of harmful and nuisance algal blooms. • Objective: Improve current understanding of the roles of external and internal nutrient loading, especially as influenced by weather forcing events. • Project includes: • in situexperiments • laboratory studies • modeling • Outputs and Outcomes: • Nutrient mass budgets for the western basin • Internal nutrient cycling budgets • Improved understanding of the causes of algal blooms • Training future scientists
Participants • Lead Investigator: Lake Erie Commission (Gail Hesse) • Science coordinator: Tom Bridgeman • Education and Outreach Coordinators: Jeff Reutter (Ohio Sea Grant), Jan Ciborowski (U. Windsor) Participating investigators • Case Western Reserve: Gerald Matisoff • Limnotech: Joe DePinto, Ed Verhamme • The Ohio State University: Justin Chaffin, Matt Thomas & divers • NCWQR: Laura Johnson, RemConfesor, Pete Richards • USGS - Great Lakes Science Center: Mary Anne Evans & divers • U. Toledo: Ricky Becker, Christine Mayer, YoungwooSeo, Song Qian
Three Subprojects • Sub-Project 1: Quantifying the internal nutrient loads to the water column in the western basin • Benthic (bottom) chamber studies • Lab-based sediment core incubations
Subprojects • Sub-Project 2:: Evaluating the important factors of river hydrology and/or seasonality of loads to harmful algal bloom formation and dynamics in the western basin of Lake Erie, including the effects of storm and other meteorological/climatological forcing events • Quantify N and P loads using: • Bayesian Hierarchical SPARROW model (BH-SPARROW) fit for the Great Lakes region • SWAT models calibrated for the Maumee and Sandusky River basins
Subprojects • Sub-Project 3:Developing a nutrient mass budget for the western basin of Lake Erie which includes sub-watersheds AND overall modeling synthesis • Apply the Western Lake Erie Ecosystem Model: • Use input data generated by Subprojects 1 and 2 • Output transport and fate of Phosphorus
