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

Practice and Principles of Isotopic Measurements in Organic Geochemistry
TL;DR: Meinschein this paper provided the notes for a short course offered in connection with the 1983 National Meeting of the Geological Society of America, but the short course drew inadequate enrollment and was cancelled.

TL;DR: In this article, the authors present results from the first worldwide round robin laboratory intercomparison, which showed large differences in retrieved isotopic signatures among participating laboratories linked to soil type and soil water content with mean differences compared to the reference water ranging from +18.1 to −108.4

Groundwater recharge, flow and hydrogeochemical evolution in a complex volcanic aquifer system, central Ethiopia
TL;DR: In this article, the authors used multivariate statistical and inverse hydrogeochemical modeling techniques to investigate groundwater recharge, flow and the hydrochemical evolution within the Akaki volcanic aquifer system, central Ethiopia.

TL;DR: It is suggested that the preferential use of deep water by red oaks allows the species to continue transpiration and growth during soil water limitations, and deeper roots may provide a buffer against drought-induced mortality.

Oxygen isotope studies of granite and migmatite, Grenville province of Ontario, Canada
TL;DR: O 18 /O 16 ratios have been obtained for rocks and minerals along a 200 mile traverse from near the Grenville front north of Lake Nipissing to the Paleozoic contact to the east of Georgian Bay.

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.
