TLDR
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.About:

First insights into the structure and environmental setting of cold-seep communities in the Marmara Sea
Bénédicte Ritt,Jozée Sarrazin,Jean-Claude Caprais,Philippe Noel,Olivier Gauthier,Olivier Gauthier,Catherine Pierre,Pierre Henry,Daniel Desbruyères +8 more
TL;DR: A brackish-water cold seep on the North Anatolian Fault (NAF) in the Marmara Sea was investigated with the Nautile submersible during the MarNaut cruise in 2007 as mentioned in this paper.
Journal ArticleDOI
Experimental investigation into partitioning of stable isotopes between scallop (Pecten maximus) shell calcite and sea water
TL;DR: In this paper, the authors show that shell depletions of Pecten maximus can be explained by the difference in solution carbonate chemistry at the site of mineralisation in the extrapallial fluid (EPF) as compared to that of the external sea water medium, from which the EPF is isolated.

Tracking the Hirnantian glaciation using Os isotopes
TL;DR: In this paper, the authors present initial 187 Os/ 188 Os (Osi) values integrated with δ 13 Corg for the first Paleozoic section of the GSSP at Dob's Linn, Scotland.

Effect of graded fructose coingestion with maltodextrin on exogenous 14C-fructose and 13C-glucose oxidation efficiency and high-intensity cycling performance.
TL;DR: Although the effect of fructose quantity on overall sprint power was unclear, the metabolic responses were associated with lower perceptions of muscle tiredness and physical exertion, and attenuated fatigue (power slope) in the Medium-Fructose and High-F fructose conditions.

On the Isotopic Chemistry of Carbonates and a Paleotemperature Scale
TL;DR: In this paper, the temperature variation of the fractionation of oxygen in exchange reactions between dissolved carbonate and water and between calcite and water was calculated on theoretical grounds, and checked experimentally.

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.

Revised carbonate-water isotopic temperature scale
TL;DR: The relationship between temperature and O(18) content relative to that for a Cretaceous belemnite of the Pee Dee formation previously reported (Epstein, Buchsbaum, Lowenstam, and Urey, 1951) has been re-determined using modified procedures for removing organic matter from shells, and is found to be 16.5 - 4.3 δ + 0.14 δ^2

The geochemistry of the stable carbon isotopes
TL;DR: A survey of the variation of the ratio C13/C12 in nature can be found in this paper, where Urey and his co-workers used two complete feed systems with magnetic switching to determine small differences in isotope ratios between samples and a standard gas.
