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:

Leaf proteome analysis of eight Populus xeuramericana genotypes: genetic variation in drought response and in water-use efficiency involves photosynthesis-related proteins.

TL;DR: Genetic variation of leaf proteome in drought response was investigated among eight Populus ×euramericana genotypes contrasting for their leaf carbon isotope discrimination, suggesting that a large intrinsic water‐use efficiency could be due to higher abundance of ribulose‐1,5‐bisphosphate carboxylase/oxygenase/ Oxygenase activase.

Isotopic ecology of the modern land snail cerion, san salvador, bahamas: preliminary advances toward establishing a low-latitude island paleoenvironmental proxy
TL;DR: In this article, variations in carbon (13C/12C) and oxygen (18O/16O) isotope ratios obtained during whole-shell and sequential-rib analyses of the modern land snail, Cerion, reveal a record of diet and local environment on San Salvador, Bahamas.

Oxygen-isotope studies of clastic diagenesis in the Lower Cretaceous Viking Formation, Alberta: implications for the role of meteoric water
Fred J. Longstaffe,Avner Ayalon +1 more
TL;DR: In this article, the paragenetic sequence of diagenetic minerals from the Lower Cretaceous Viking sandstone and conglomerate from south-central Alberta, Canada have been used to identify changes in porewater composition during diagenesis and to relate these changes to major geological events within the western Canada sedimentary basin.

Fresh-water carbonates from the Lower Freshwater Molasse (Oligocene, western Switzerland): sedimentology and stable isotopes
TL;DR: In this article, stable isotope analyses were carried out on 46 calcite samples and data from matrix and intraclasts reveal typical fresh-water compositions (δ13C = −5 to −75‰ ; δ18O = −55 to −9‰ ) and a weak co-variant trend suggests deposition in hydrologically closed lakes, although the range of δ13c values recorded is also consistent with pedogenetic overprinting associated with subaerial exposure.

Recording of El Niño in ice core δ18O records from Nevado Huascarán, Peru
TL;DR: In this article, the 68-year resolved time series of δ 18 O from ice cores retrieved from the glaciated col of Nevado Huascaran, Peru (9°S, 77°W, 6050 m) reflects climate variability over Amazonia and the western tropical Atlantic.

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.
