Environmental Sensor Network at the Lake Erie Center Selected Preliminary Results Early analysis of the fluxes at the marshland site revealed that the wetland released evident methane especially during daytime at a much higher magniudethan other temperate wetlands. The cropland generally releesmethane during the daytime, and uptakes small amounts of methane at night. However, the orders of methane fluxes in the cropland are much smaller than in the marshland. Project Overview The Environmental Sensor Network (ESN) includes six eddy covariance (EC) flux tower monitoring stations to measure fluxes across the Western basin of Lake Erie, including two stations (PermS1, PermS2) on permanent structures in Lake Erie, a vessel-mounted station on the LEC’s research boat (BoatS), a station in an agricultural field, a station in a coastal wetland and large tower station in a mixed oak forest known as “Oak Openings”. ESN is a contributing member of the Global Lake Ecological Observatory Network (GLEON) and the Ameriflux Network. Biometric and chamber based measurements of ancillary ecosystem characteristics are conducted at both the site and watershed scales. Western basin, Lake Erie CO2, H2O, and energy fluxes of a freshwater lake ecosystem on top of the city of Toledo water intake crib. Western basin, Lake Erie CO2, H2O, and energy fluxes of a freshwater lake ecosystem on top of the U.S. Coast Guard’s Toledo Light #2 light beacon. Swanton, Ohio The Oak Openings Metro Park is the sole Amerifluxtower site in Ohio. Measuring the carbon sequestration capacity of managed forest ecosystems. Curtice, Ohio CO2, CH4, H2O, N2O, and energy fluxes in an agricultural field are measured using an open-path eddy covariance system and static chambers. Port Clinton, Ohio CO2, CH4, H2O, and energy fluxes in a managed coastal wetland ecosystem along the Lake Erie shoreline. The working framework The ESN is a real-time platform that focuses on net ecosystem exchange of greenhouse gases (CO2, CH4, H2O, and energy) as well as the physical, chemical and biological properties of the western basin of Lake Erie. All data, including those of six flux towers, will be open access to promote education, research, and public awareness. Acknowledgements The ESN is funded by the FSML program of the National Science Foundation, National Oceanic and Atmospheric Administration and the United States Department of Agriculture Forest Service. It is overseen by Dr. Jiquan Chen, Dr. Carol Stepien, Dr. Johan Gottgens, Dr. Richard Becker, Dr Thomas Bridgeman, and Dr. Kevin Czajkowski at the University of Toledo.
