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

Vertical profiles of HDO/H2O in the troposphere
TL;DR: In this paper, the authors reanalyzes the measurements of the D content in tropospheric water vapor by Ehhalt (1974) correcting for the isotopic contamination by wall water in the sampling tubes.

Development of Magnesian Carbonates in Quaternary Soils on the Island of Hawaii
TL;DR: In this article, the conditions of the development of sedimentary magnesian carbonates were investigated in a Quaternary weathering chronosequence (5-350 ka) on the island of Hawaii.
Stable and strontium isotopic profiles through hydrothermally altered upper oceanic crust, Hole 504B
TL;DR: In this paper, the authors reported that the lower dikes were altered by seawater-derived hydrothermal fluids, with little change in the Sr concentrations of the rocks, and the seawater component of the fluids increased through time, as documented by Sr/Sr ratios of 0.7028-0.7034 for amphibole and chlorite.

Intense silicification of footwall sedimentary rocks in the stockwork alteration zone beneath the Brunswick No. 12 massive sulphide deposit, Bathurst, New Brunswick
TL;DR: The Brunswick No. 12 massive sulphide deposit in northern New Brunswick as discussed by the authors resembles silicified volcaniclastic mudstones described in the immediate footwall of the first section of this paper.

Calibration of δ17O and δ18O of international measurement standards – VSMOW, VSMOW2, SLAP, and SLAP2
TL;DR: In this article, two replacement calibration materials, Vienna Standard Mean Ocean Water (VSMOW) and Standard Light Antarctic Precipitation (SLAP), were created with isotopic compositions as close as possible to the original standards in their D/H and 18O/16O ratios.

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.
