Isotopic identification of soil and permafrost nitrate sources in an Arctic tundra ecosystem

The nitrate (NO 3 – ) dual isotope approach was applied to snowmelt, tundra active layer pore waters, and underlying permafrost in Barrow, Alaska, USA, to distinguish between NO 3 – derived from atmospheric deposition versus that derived from microbial nitrification.
