Direct gaseous emissions of methane (CH4) and carbon dioxide (CO2) from the subglacial environment under Greenland Ice Sheet (GrIS) were only recently discovered and it is yet to be determined how important it is for the panarctic carbon budget. We measured in situ net gaseous emissions of subglacial CH4 and CO2, dissolved concentrations and isotopic composition of gases (13C and 2H) at the onset, near maximum, and at the end of the melt season in 2018 and 2019. We found a tight relation between gaseous and dissolved CH4 and CO2, respectively, indicating that degassing from the subglacial meltwater is the main source of these gases in the subglacial air. The diurnal variability of in situ mole fractions of CH4 and CO2 in subglacial air was ...
