NITEDC: Winter snow pits for nitrate concentration and oxygen and nitrogen isotopic ratio measurements collected during the winterover 2008/2009/2010.Entry ID: 1011_5_IPEV_FR
Abstract: This dataset presents the concentration and oxygen and nitrogen isotopic ratio profile of snow nitrate collected during the winterover 2008 at the Concordia station (Antarctica). Depth resolution is 2cm and maximum depth 20cm. Sampling frequency is every 10 days. Samples were bagged/sealed and analyzed for concentration on site the next summer season. Isotopic ratio measurements will be performed at Grenoble, France.
Same work as been done for 2009 and 2010.

Horizontal Resolution Range: < 1 meter
Vertical Resolution: 2cm
Vertical Resolution Range: < 1 meter
Quality Isotopic ratios are calibrated against international references held by the IAEA. Concentration measurements are calibrated against internal standards based on mass-weighted nitrate salts.
