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 Review of Water Isotopes in Atmospheric General Circulation Models: Recent Advances and Future Prospects
TL;DR: In this paper, the authors reviewed and synthesized key advances accomplished in modeling surface evaporation, condensation, supersaturation, postcondensation processes, vertical distribution of water isotopes, and spatial δ(18)O-temperature slope and utilizing spectral nudging technique.

Characterization of a carbonate karstic aquifer flow system using multiple radioactive noble gases (3H-3He, 85Kr, 39Ar) and 14C as environmental tracers
Naama Avrahamov,Yoseph Yechieli,Roland Purtschert,Yehuda Levy,Jürgen Sültenfuß,Virginie Vergnaud,Avihu Burg +6 more
TL;DR: In this article, the authors used tritium (3H)-3He, 85Kr CFCs, SF6, and quantification of mixing between them to identify the mixing between young and older water components.
Oxygen and hydrogen isotope study of minerals from metapelitic rocks, staurolite to sillimanite zones, Mica Creek, British Columbia
John R. Bowman,Edward D. Ghent +1 more
TL;DR: In this paper, the authors made a comparison between the results of /sup 18/O and delta D values of coexisting quartz, ilmenite, muscovite and biotite from Late Precambrian metapelitic rocks, staurolite-kyanite to K-feldspar-muscovites-sillimanite zones, from Mica Creek, British Columbia.

Geochemical signature of aquitard pore water and its paleo-environment implications in Caofeidian Harbor, China
TL;DR: Wang et al. as mentioned in this paper found that aquitard pore water was of meteoric origin and was basically not influenced by evaporation, according to the δ18O profile and positive correlation between deuterium and Cl−.

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.
