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

The tropospheric cycle of H2: a critical review
Dieter H. Ehhalt,Franz Rohrer +1 more
TL;DR: In this paper, the distribution, budget and isotope content of molecular hydrogen (H 2 ) in the troposphere is reviewed and the current budget analyses can be divided in two classes: bottom-up, in which the source and sink terms are estimated separately based on emission factors and turnover of precursors and on global integration of regional loss rates, respectively.

Oxygen isotope ratios in coexisting minerals of regionally metamorphosed rocks
G. Donald Garlick,Samuel Epstein +1 more
TL;DR: The O 18 /O 16 ratios of coexisting minerals from a number of regionally metamorphosed rocks have been measured, using a bromine pentafluoride extraction-technique as discussed by the authors.

Holocene changes in atmospheric circulation recorded in the oxygen-isotope stratigraphy of lacustrine carbonates from northern Sweden.
TL;DR: In this article, the oxygen-isotope composition of local precipitation (delta(18)O(P)) is reconstructed from carbonate lake-sediment components in a sediment core covering the last 10000 calendar years from Lake Tibetanus, a small, hydrologically open, groundwater-fed take in the Abisko area, northern Sweden.
Journal ArticleDOI
DH Ratios and late-stage dehydration of shales during burial
TL;DR: In this paper, the isotope fractionation factor (α) between the OH hydrogen in clay minerals and water was estimated to decrease by about 0.00016 ± 0.00003 per °C increase in temperature (in the range 29-120°C).

Oxygen isotopic evidence for vigorous mixing during the Moon-forming giant impact
Edward D. Young,I. E. Kohl,Paul H. Warren,David C. Rubie,Seth A. Jacobson,Seth A. Jacobson,Alessandro Morbidelli +6 more
TL;DR: The results indicate that the late veneer impactors had an average Δ′17O within approximately 1 per mil of the terrestrial value, limiting possible sources for this late addition of mass to the Earth-Moon system.

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.
