Greenhouse gas fluxes and concentrations and associated habitat data in western Dane County, Wisconsin, USA, streams during the 2018 growing season

Streams are often sources of carbon dioxide (CO2) and methane (CH4),
particularly in agricultural regions where sediment and organic matter
inputs can be substantial. Floods are occurring more often and more
intensely in southern Wisconsin, one such agricultural region, due to
climate change and few studies have investigated how floods impact
stream CO2 and CH4 fluxes and concentrations. I compared
concentrations and fluxes of CO2 and CH4 with greater than 30
variables representing in-stream and watershed attributes at 10 sites
in mixed agricultural and suburban locations in southern Wisconsin.
Sampling was conducted 10 times at each site during the growing season
(May-November) in 2018
