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

TL;DR: In this paper, the authors present a new method allowing for an extensive and straightforward characterisation of the complex nature of such isotopologue remote sensing datasets, and they demonstrate that the MUSICA humidity profiles are representative for most of the troposphere with a vertical resolution ranging from about 2 km (in the lower troposphere) to 8 km(in the upper troposphere), with an estimated precision of better than 10%.

sol18O16O of Archean clastic metasedimentary rocks: a petrogenetic indicator for Archean gneisses?
TL;DR: The oxygen isotopic compositions of over 100 Archean clastic metasedimentary, felsic metavolcanic and gneissic rocks from selected areas within the Superior Province have been determined.

Oxygen isotopes in marine diatoms: A comparative study of analytical techniques and new results on the isotope composition of recent marine diatoms
TL;DR: In this article, the isotope analysis of marine diatoms was performed in two independent ways: stepwise fluorination of hydrous opal-A and a method of controlled isotope exchange before silica dehydration.

Field applicability of Compound-Specific Isotope Analysis (CSIA) for characterization and quantification of in situ contaminant degradation in aquifers
TL;DR: This mini-review aims at guiding practical users towards the sound interpretation of CSIA field data for the characterization of in situ contaminant degradation by evaluating factors that can influence isotope fractionation during biodegradation, as well as potential isotope-fractionating and non-isotope- fractionating physical processes governing observed isotope fractions in the field.

Variations of 18O/16O in plants from temperate peat bogs (Switzerland): implications for paleoclimatic studies
TL;DR: In this article, a detailed study of surface waters within one bog showed that δ18O-values vary widely and are closely related to the micro-topography of the bog surface.

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.
