Abstract

Simulation of δ15N and δ18O scale contraction, given the observation of the fraction of O atom exchange with water and blanks.

Sampling and analytical procedures: 

Effects of sample volume and salinity on O atom exchange with water

δ15O and δ18O scale contraction were simulated given the observations of the fraction of O atom exchange with water during denitrification, blanks originating from the bacterial concentrates, from equilibration with atmospheric N2O, or from NO3- contamination of the water into which the standards were diluted.
