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:

Journal ArticleDOI
High-precision determination of nitrogen stable isotope ratios at the sub-nanomole level
TL;DR: In this paper, the authors describe a mass spectrometer, gas inlet and operating protocol which have been developed for the purpose of making stable isotope measurements of subnanomole quantities of nitrogen gas.

Fundamentals of Stable Isotope Chemistry and Measurement
Todd E. Dawson,Paul D. Brooks +1 more
TL;DR: A good introduction to stable isotope chemistry can be found in this article, where the ratios of biologically relevant lighter stable isotopes of H, C, N, O, and S in the biosphere are measured using modern isotope ratio mass spectrometers (IRMS).
Journal ArticleDOI
Variability of stable isotopes and maximum linear extension in reef-coral skeletons at Kaneohe Bay, Hawaii
TL;DR: Results imply that natural inter- and intraspecific variability in coral skeletal 13C, 18O, and MLSE should be considered when interpreting and comparing coral-based tropical paleoclimate data from various coral species, depths, and field sites.

Calcrete and palustrine assemblages on a distal alluvial-floodplain: A response to local subsidence (Miocene of the Duero basin, Spain)
TL;DR: In the upper Miocene of the eastern Duero basin, two carbonate units (CU-1 and CU-2) display a lateral transition from distal alluvial-floodplain red mudstones to calcrete and an upwards transition from calcrete to palustrine facies as mentioned in this paper.

Late pleistocene/early holocene environments and climates, fauna, and human occupation in the argentine altiplano

TL;DR: The Barro Negro site (23°S lat., 65°37′W long) in the Altiplano (Puna) of northwestern Argentina contains a well stratified sequence of remains of Hippidion, the American extinct horse, camelids, and archaeological materials, which is the focus of.

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.
Journal ArticleDOI
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
Journal ArticleDOI
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.
