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

Isotopic characteristics of ice cover in a large northern river basin
John J. Gibson,Terry D. Prowse +1 more
TL;DR: In this paper, the isotope stratigraphy of river-ice covers can be applied to reconstruct time-series of the stable isotopic composition of winter streamflow, although careful attention to ice type, morphology and location of sampling is required to obtain useful results.

Oxygen isotopic compositions of Central Andean plutonic and volcanic rocks, latitudes 26°–29° south
TL;DR: Oxygen isotope data for 27 igneous rocks of Mesozoic to Quaternary age from the Central Andes were reported in this article, with δ 18 O values between 6.2 and 8.3.
Climatic controls on water vapor deuterium excess in the marine boundary layer of the North Atlantic based on 500 days of in situ, continuous measurements

TL;DR: In this article, continuous, in situ measurements of water vapor isotopic composition have been conducted in the North Atlantic, at the Bermuda Islands (32.26° N, 64.88° W), between November 2011 and June 2013, using a cavity ring-down spectrometer water vapor analyzer and an autonomous self-designed calibration system.

How Rossby wave breaking modulates the water cycle in the North Atlantic trade wind region

TL;DR: In this paper, stable water isotopes are used as tracers for the origin of air parcels arriving in the sub-cloud layer above Barbados, measured continuously in water vapour at the Barbados Cloud Observatory during a 24-day measurement campaign.

Black shale deposition and early diagenetic dolomite cementation during Oceanic Anoxic Event 1: The mid-Cretaceous Maracaibo Platform, northwestern South America

TL;DR: In this paper, the authors show that the interstitial euhedral dolomite has a medium crystallinity and exhibits unusual textural relations with framboidal pyrite and gypsum, which can be genetically related to minor sea-level changes, proximal turnovers in marine productivity, and sudden climate shifts affecting mid-Cretaceous shoaling upward, shallow marine, carbonate cyclicity.

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.
