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

Oxygen and hydrogen isotope ratios of monthly collected waters from Nasudake Volcanic Area, Japan
TL;DR: In this article, the authors measured the monthly variation of δD and δ18O of two fumarolic condensates, five hot spring waters, two stream waters, and meteoric precipitation at the Nasudake volcanic area of Japan.

TL;DR: It was observed that temporal variations of δ18O and δ2H in precipitation were consistent with the meteorological parameters derived from HYSPLIT, particularly precipitation amount along the trajectory and mix depth, but are not dependent on vapour residence time in the atmosphere.

Oxygen isotope study of evaporating brines in Sambhar Lake, Rajasthan (India)
TL;DR: In this article, the isotopic evolution of oxygen in the lake waters during the annual evaporation cycle is explained through the Craig-Gordon model taking into account the fluctuation in lake water volumes due to evapuration, equilibrium and kinetic fractionation factors, and the effect of changing seasonal temperature and humidity.

Self‐diffusion of carbon and oxygen in dolomite
TL;DR: In this article, self-diffusion coefficients of both carbon and oxygen in dolomite are approximately 100 times larger than the values in calcite over the temperature range investigated.

Identification of geographical influences and flow regime characteristics using regional water isotope surveys in the lower Nelson River, Canada
TL;DR: A 3-year monitoring initiative (2010-2013) of stable water isotopes (δ18O and δ2H) at over 50 hydrometric sites in the lower portion of the Nelson River Basin, a key freshwater-marine corridor in Canada with global significance is reported in this paper.

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.
