Comparison of stable isotope reference samples
Use of light stable isotope ratio measurements has proliferated in the past decade. The need for procuring additional stable isotope reference materials was recognized at an International AtomicExpand
Reporting of stable hydrogen, carbon, and oxygen isotopic abundances
To eliminate possible confusion in the reporting of isotopic abundances on non-corresponding scales, the Commission on Atomic Weights and Isotopic Abundances recommended at the 37 th General AssemblyExpand

TLDR
The recommendations presented herein are designed to clarify expression of quantities related to measurement of isotope and gas ratios to ensure that quantity equations instead of numerical value equations are used for quantity definitions. Expand
Distribution of oxygen-18 and deuterium in river waters across the United States†
Reconstruction of continental palaeoclimate and palaeohydrology is currently hampered by limited information about isotopic patterns in the modern hydrologic cycle. To remedy this situation and toExpand
Normalization of oxygen and hydrogen isotope data
To resolve confusion due to expression of isotopic data from different laboratories on non-corresponding scales, oxygen isotope analyses of all substances can be expressed relative to VSMOW or VPDBExpand
New Guidelines for δ13C Measurements
Consistency of δ13C measurements can be improved 39−47% by anchoring the δ13C scale with two isotopic reference materials differing substantially in 13C/12C. It is recommended that δ13C values ofExpand
Reporting of stable hydrogen, carbon, and oxygen isotopic abundances (Technical Report)
To eliminate possible confusion in the reporting of isotopic abundances on noncorresponding scales, the Commission on Atomic Weights and Isoto ic Abundances recommended at the 37* General Assembly atExpand
Oxygen isotopes in nitrate: new reference materials for 18O:17O:16O measurements and observations on nitrate-water equilibration.
TLDR
These new reference materials, combined with previously distributed NO(3) (-) isotopic reference materials IAEA-N3 (=IAEA-NO-3) and USGS32, can be used to calibrate local laboratory reference materials for determining offset values, scale factors, and mass-independent effects on N and O isotope-ratio measurements in a wide variety of environmental NO( 3)(-) samples.

Calibration of the calcite–water oxygen-isotope geothermometer at Devils Hole, Nevada, a natural laboratory
Abstract The δ 18 O of ground water (−13.54 ± 0.05 ‰) and inorganically precipitated Holocene vein calcite (+14.56 ± 0.03 ‰) from Devils Hole cave #2 in southcentral Nevada yield an oxygen isotopicExpand
