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

Carbon- and oxygen-isotope composition of the cuttlebone of Sepia officinalis: a tool for predicting ecological information?
V. Bettencourt,Ángel Guerra +1 more
TL;DR: The first detailed work undertaken on the isotope composition of coleoid cephalopods with a maximum life span of 2 yr, a year-round spawning season, and variable growth rates among and within individuals have been inferred from the isotopic temperatures.

Limnology of two Antarctic epishelf lakes and their potential to record periods of ice shelf loss
James Smith,James Smith,Dominic A. Hodgson,Michael J. Bentley,Elie Verleyen,Melanie J. Leng,Steven J. Roberts,Steven J. Roberts +7 more
TL;DR: In this article, the authors measured water column chemistry and sampled the water column and sediments of two epishelf lakes along vertical and horizontal transects, Moutonnee and Ablation, to detect past changes in the presence or absence of the ice shelf.

Decrease of river runoff in the upper waters of the Eurasian Basin, Arctic Ocean, between 1991 and 1996: Evidence from δ18O data

TL;DR: In this article, the authors measured the H218O/H216O ratio of water from two sections crossing the Eurasian Basin in 1991 and 1996 and found that the observed decrease in the freshwater contained in the upper waters of the Amundsen Basin during the 1990s is due to decrease in meteoric water (mainly river runoff).

Forest-tundra water balance signals traced by isotopic enrichment in lakes
TL;DR: In this paper, isotopic signals in each lake trace water balance and atmospheric conditions integrated over different time-periods and spatial areas, as determined by lake water-residence time and catchment drainage area.

TL;DR: The leading cause of outliers appeared to be improper calibration or compromised storage of laboratory standard and primary reference waters; hence the importance of judicious storage of lab standards cannot be understated.

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.
