The d18O values are in the reported range for atmospheric nitrate in other parts of the globe, and will tend to reflect the relationship between NOy oxygen and H2O þ O2 in the troposphere immediately prior to nitrate deposition. d15N values, however, are lower than those for atmospheric nitrate over most parts of the globe, but show similarities to 15N/14N ratios reported for atmospheric nitrate in the Antarctic.
