Seasonal variations in N and O isotopes of nitrate in snow at Summit, Greenland: Implications for the study of nitrate in snow and ice cores

Nitrogen and oxygen isotopes of NO3− have been measured in snow and firn from Summit, Greenland. The 15N/14N and 18O/16O ratios of NO3− in recently fallen snow are similar to those of surface snow. Diurnal variation is observed in 15N/14N of NO3−, and possibly 18O/16O, suggesting fractionating loss...
