This study investigates methane fluxes in diverse ecosystems surrounding Lake Erie, focusing on marshlands and croplands. Utilizing a vessel-mounted flux tower, data were collected during a microcystis algal bloom at the Maumee River and near permanent stations in the Western Basin. Findings reveal significant methane emissions from marshlands during the day, while croplands exhibit lower fluxes with nighttime uptake. This research, supported by NSF, NOAA, and USDAFS, highlights the ecological dynamics of greenhouse gas emissions in coastal and agricultural environments.

Presentation Transcript

  1. Environmental Sensor Network Lake Erie Center, University of Toledo

  2. Station Locations

  3. The Working Framework

  4. Station designs

  5. Route of the Vessel-Mounted Flux Tower • Through the microcystis algal bloom at the estuarine of the Maumee River • Through the sedimentary flow south of the Detroit River • Measurements taken near permanent stations in the Western basin (PermS1, PermS2)

  6. Marshland (coastal wetland) and Cropland (agricultural field) Sites • Marshland releases evident methane during the day • Cropland releases methane during the day and uptakes small amounts during the night • The orders of methane fluxes are much smaller in the cropland than in the marshland.

  7. Acknowledgments • Partially funded by the FSML program of the NSF, NOAA, and USDAFS • Overseen by Jiquan Chen, Carol Stepien, Michael Deal, Johan Gottgens, Housen Chu, Richard Becker, Thomas Bridgeman, and Kevin Czajkowski at The University of Toledo
