Station Locations

The Working Framework

Station designs

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)

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.
