NITEDC: Spatial variability at the meter scale of nitrate concentration and isotopic composition based on three shallow snow pits (70cm depth) dug at the Concordia station (Antarctica) in summer field season 2007/2008.
This dataset presents the concentration and oxygen and nitrogen isotopic ratios of nitrate in three 70 cm depth snow pits collected in the clean area of the Concordia station during the field season 2007/2008. The first snow pit was collected 2007-12-18, the second 2007-12-28 and the third 2008-01-15. Resolution is around 2cm depth. Dataset gives depth, concentration in ppbw and isotopic ratios (in permil with respect of SMOW and Air-N2 reference scales).
