A CH4 emission estimate for the Kuparuk River basin, Alaska
Integrated annual methane fluxes measured from 1994 to 1996 at sites representing specific tundra vegetation and land cover types were weighted areally using a vegetation map [Auerbach et al., 1997] for the Kuparuk River basin and subareas. Wetland and open water CH4 emissions dominate the Kuparuk R...
