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

8. abyssal peridotites from odp hole 670a (21°10'n, 45°02'w): residues of mantle melting exposed by non-construct ive axial divergence 1
TL;DR: The Ocean Drilling Program's Hole 670A is located 45 km south of the Kane Fracture Zone as discussed by the authors, and the average peridotite in the group of 18 studied has 68% of its original mineralogy replaced by serpentine and related minerals.

The influence of Congo River discharges in the surface and deep layers of the Gulf of Guinea
Annick Vangriesheim,Catherine Pierre,Alain Aminot,Nicolas Metzl,François Baurand,Jean-Claude Caprais +5 more
TL;DR: For example, Ifremer et al. as discussed by the authors investigated the influence of the Congo River discharges, both in the surface layer and in the deep and near-bottom layers.

The ground-based FTIR network's potential for investigating the atmospheric water cycle
TL;DR: In this paper, Tropospheric H216O and HD16O/H216O vapour profiles measured by ground-based FTIR (Fourier Transform Infrared) spectrometers between 1996 and 2008 at a northern hemispheric subarctic and subtropical site (Kiruna, Northern Sweden, 68° N and Izana, Tenerife Island, 28° N, respectively) were compared to an isotope incorporated atmospheric general circulation model (AGCM).

Paleomobility in the Tiwanaku diaspora: Biogeochemical analyses at Rio Muerto, Moquegua, Peru
Kelly J. Knudson,Paul S. Goldstein,Allisen C. Dahlstedt,Andrew D. Somerville,Margaret J. Schoeninger +4 more
TL;DR: Radiogenic strontium and oxygen isotope data from human burials from three cemeteries in the Tiwanaku-affiliated Middle Horizon archaeological site complex of Rio Muerto contribute to the role of diversity in ancient states by demonstrating the range of geographic origins rather than simply colonists from the Lake Titicaca Basin.

Origin of dissolved solids in groundwaters of Mayne Island, British Columbia, Canada
TL;DR: In this article, the authors applied hydrogeological, hydrochemical and isotope techniques to determine the origin of saline groundwaters on Mayne Island in the Strait of Georgia, British Columbia.

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.
