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

Isotope analysis of the nutrient supply in Xiangxi Bay of the Three Gorges Reservoir
TL;DR: In this article, stable isotopes of hydrogen (δD) and oxygen (γ 18 O), nutrients, and flow velocity were observed from September 2012 to December 2013 in Xiangxi Bay (XXB), the largest tributary bay in the lower reach of the Three Gorges Reservoir (TGR).

Oxygen isotope evidence for the genesis of Upper Paleozoic granitoids from southwestern Nova Scotia
TL;DR: The oxygen isotope ratios for 127 rocks and coexisting minerals from Paleozoic granitoids and clastic metasedimentary rocks of southwestern Nova Scotia have been measured as mentioned in this paper.

Land-air boundary environment as recorded by the18O/16O and13C/12C isotope ratios in the shells of land snails
TL;DR: In this paper, a yearly cycle of carbon and oxygen isotope composition of shells of the Israeli land snail Xeropicta vestalis is presented, which indicates that the snails use water from the land-air boundary zone.

CO2 intrusion in freshwater aquifers: Review of geochemical tracers and monitoring tools, classical uses and innovative approaches
TL;DR: A review of applied geochemical methods for monitoring CO2 leakage focusing on shallow freshwater aquifers overlying CO2 storage areas is presented in this article, where the authors classified the monitoring/tracing tools into two groups: (A) direct indicators of the CO2 itself, and (B) indirect indicators (i.e. reaction products) of the presence of CO2 that take into account displacement of the chemical equilibria under the conditions imposed by CO2 dissolution.

Isotope geochemistry of water in Gulf Coast salt domes
TL;DR: Water found as active leaks and isolated pools in the Weeks Island, Jefferson Island, and Belle Isle salt mines of south Louisiana has delta/sup 18/O values ranging from -4 to +11.1.

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.
Journal ArticleDOI
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.
