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 determination of the D/H ratio of non-exchangeable hydrogen in cellulose extracted from aquatic and land plants
TL;DR: In this article, a method has been developed for the analysis of D/H ratios of non-exchangeable hydrogen in plant cellulose and the overall relationship is linear with slope of one and intercept of −22%.

Snowmelt runoff from measurements of tritium and oxygen‐18
TL;DR: In this paper, the tritium and oxygen-18 content of precipitation, snowpack, and runoff in a small mountain basin in Northern Czechoslovakia was studied by measuring the trite content of the baseflow and the subsurface runoff.

Recharge mechanisms and geochemical processes in a semi-arid sedimentary basin, Eastern Cape, South Africa
TL;DR: In this article, stable isotope (18 O and 2 H) and geochemical signatures are used to gain some insight into recharge processes and groundwater salinization mechanisms in a semi-arid rangeland catchment.

Geochemistry and origin of formation waters in the western Canada sedimentary basin—I. Stable isotopes of hydrogen and oxygen
Brian Hitchon,Irving Friedman +1 more
TL;DR: In this article, stable isotopes of hydrogen and oxygen, together with chemical analyses, were determined for 20 surface waters, 8 shallow potable formation waters, and 79 formation waters from oil fields and gas fields.

Stable isotope survey of the fresh water occurrences in Israel and the Northern Jordan Rift Valley
J.R. Gat,W. Dansgaard +1 more
TL;DR: In this article, the stable isotope composition (Oxygen-18 and Deuterium) of the meteoric water cycle in Israel is presented, and the isotope data are used to assess the hydrographical structure of the combined Jordan flow and the role water loss by evaporation plays in the system's water balance.

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.
