Greenhouse gases in arctic and alpine streams: patterns, drivers, and responses to disturbance
Streams have recently received attention as previously unaccounted for sources of greenhouse gases (GHG; CH4,CO2, and N2O) to the atmosphere. While progress has been made at incorporating streams into global estimates of GHG flux, many spatial gaps remain, especially in remote regions of the Siberian Arctic and high elevation ecosystems worldwide. To address a critical gap in regional estimates of emissions and better understand the sources of variability of those emissions, we quantified the vertical flux of CH4, N2O, and CO2 and examined the sources of variability and spatial-temporal patterns ...
