The international standard is Vienna Pee Dee Belemnite (VPDB).

CARBON RELIANCE ON DISSOLVED INORGANIC CARBON OF JUNIOR AND MATURED REED BEDS INDICATED BY STABLE ISOTOPE ANALYSIS

The values of the isotopic ratios of carbon ([delta][.sup.13]C) and nitrogen ([delta][.sup.15]N) ([per thousand]) were compared with the universal references of PDB (Pee Dee Belemnite) and atmospheric nitrogen (Fry, 2003), respectively.

The procedures for calculating isotope ratios are universally based on the following calculations: the isotopic differences between various materials are exceedingly small, so isotopic composition is reported relative to an internationally accepted standard (air for N and Pee Dee Belemnite for C).
