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

Carbonate aquifers threatened by legacy mining: hydrodynamics, hydrochemistry, and water isotopes integrated approach for spring water management
Marco Doveri,Stefano Natali,Stefano Natali,Linda Franceschi,Matia Menichini,Sandra Trifirò,Roberto Giannecchini +6 more
TL;DR: In this paper, the authors investigated the origin and hydrochemical evolution of groundwater and evaluated their possible interactions with sources of potentially toxic elements, such as acid mine drainages and thallium-contaminated surface waters.

Formation of hydrothermal carbonate in Lake Tanganyika, East-Central Africa
P. Stoffers,Reiner Botz +1 more
TL;DR: In this paper, carbonates are associated with recent and sub-recent hydrothermal fluids emerging from the lake floor, probably from mixtures of aragonite and calcite with lake water.

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.
