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 atmospheric water cycle of a coastal lagoon: An isotope study of the interactions between water vapor, precipitation and surface waters
Daniele Zannoni,Hans Christian Steen-Larsen,Giancarlo Rampazzo,Giuliano Dreossi,Barbara Stenni,Andrea Bergamasco +5 more
TL;DR: In this paper, the authors presented a framework of the isotopic composition of the atmospheric water cycle components (water vapor and precipitation) for the coastal lagoon of Venice (Italy) and discussed the interaction between the atmospheric component and the surface component of the local water cycle.

Groundwater hydrochemistry and isotope geochemistry in the Turpan Basin, northwestern China
TL;DR: In this paper, the relationship of major elements (K+, Na+, Ca2+, Mg2+, HCO3−, SO42− and Cl−) and environmental isotopes (δ18O, δ2H and T) in groundwater were analyzed to investigate the evolution of the regional hydrochemistry within the Turpan Basin.

Biogeochemical reconstructions of life histories as a method to assess regional interactions: Stable oxygen and radiogenic strontium isotopes and Late Intermediate Period mobility on the Central Peruvian Coast
TL;DR: In this article, the authors assess the potential for radiogenic strontium and stable oxygen isotopic reconstruction of mobility over the life course to shed light on the regional interactions of coastal Ychsma groups during the Late Intermediate Period.

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.
