Denitrification is the main source of N2O emissions from cryoturbated peat circles in the Eastern European Arctic tundra. These permafrost-affected bare peat circles lack vegetation, have a high amount of available nitrate, and a low carbon to nitrogen ratio. Together with a soil moisture of ~ 70%,...
