Standard for Reporting Concentrations of Deuterium and Oxygen-18 in Natural Waters.
TLDR
A standard, based on the set of ocean water samples used by Epstein and Mayeda to obtain a reference standard for oxygen-18 data, but defined relative to the National Bureau of Standards isotopic reference water sample, is proposed for reporting both deuterium and oxygen- 18 variations in natural watersrelative to the same water.Abstract:
A standard, based on the set of ocean water samples used by Epstein and Mayeda to obtain a reference standard for oxygen-18 data, but defined relative to the National Bureau of Standards isotopic reference water sample, is proposed for reporting both deuterium and oxygen-18 variations in natural waters relative to the same water. The range of absolute concentrations of both isotopes in meteoric-waters is discussed.read more

A model of the Earth's Dole effect
Georg Hoffmann,Matthias Cuntz,Christine Weber,Philippe Ciais,Pierre Friedlingstein,Martin Heimann,Jean Jouzel,Jörg Kaduk,Ernst Maier-Reimer,Ulrike Seibt,Katharina Six +10 more
TL;DR: In this article, a model of the Earth's Dole effect was developed by combining the results of three-dimensional models of the oceanic and terrestrial carbon and oxygen cycles with results of atmospheric general circulation models with built-in water isotope diagnostics.

Oxygen isotope fractionation between zoisite and water
TL;DR: In this article, the zoisite-waier exchange reaction takes place extremely slowly and consequently direct-exchange calibration of equilibrium 18 O 16 O fractionation factors was possible only at 600 and 700°C.

Isotopic Variations in Meteoric Waters
TL;DR: The relationship between deuterium and oxygen-18 concentrations in natural meteoric waters from many parts of the world has been determined with a mass spectrometer and shows a linear correlation over the entire range for waters which have not undergone excessive evaporation.

Isotopic standards for carbon and oxygen and correction factors for mass-spectrometric analysis of carbon dioxide
TL;DR: In this paper, Niee's and Solenhofen standards were compared to the Chicago PDB standard for carbon and oxygen isotope ratios, and the correction factors for instrumental effects and for the nature of the mass spectra were derived.

Variation of O18 content of waters from natural sources
S Epstein,Toshiko K. Mayeda +1 more
TL;DR: A number of marine water and fresh water samples were examined for the relative O18O16 ratio, and the variation of this ratio was determined to a precision of ± 1% as mentioned in this paper.

Effect of Low Concentrations of Carbon Dioxide on Photosynthesis Rates of Two Races of Oxyria.
TL;DR: Alpine plants of Oxyria digyna have higher apparent photosynthesis rates at various carbon dioxide concentrations than arctic, sea-level plants of the same species, which may be involved in the survival of plants at high elevations.
