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

Oceanic Erosion of a Floating Antarctic Glacier in the Amundsen Sea
TL;DR: A survey of the southern Amundsen and Bellingshausen seas in early 1994 included the first deep oceanographic measurements along the calving front of Pine Island Glacier, which drains 2x10^5 km^2 of the marine-based West Antarctic Ice Sheet.

Oxygen isotope constraints on the petrogenesis of volcanic arc magmas from Martinique, Lesser Antilles
TL;DR: In this article, a two-stage model is proposed for the origin and differentiation of island-arc magmas on Martinique, where crystal fractionation is accompanied by contamination with isotopically distinct crust, including terrigenous sediments.

Oxygen Isotope Stratigraphy
TL;DR: In this paper, the authors present oxygen isotope curves for Phanerozoic foraminifera, mollusks, brachiopods, and conodonts, and Precambrian limestones, dolostones, and cherts.

Isotopic disequilibrium in travertine deposition
TL;DR: The isotopic composition of travertines, CO 2, H 2 O and HCO3− from springs, and modern and fossil deposits of Central Italy is reported in this article, which confirms the fact that travertine deposition does not take place at the isotopic equilibrium point.

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.
