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:

Rapid Growth Rates of Syndepositional Marine Aragonite Cements in Steep Marginal Slope Deposits, Bahamas and Belize
G. Michael Grammer,Robert N. Ginsburg,Peter K. Swart,Donald F. McNeill,A. J. Timothy Jull,Dennis R. Prezbindowski +5 more
TL;DR: Growth rates of marine botryoidal aragonite cements from steep (35-45°) marginal slope deposits in the Bahamas and Belize have been determined by accelerator mass spectrometer radiocarbon dating of samples taken at the base and top of individual botryoids.
Journal ArticleDOI
Diurnal fluxes and the isotopomer ratios of N2O in a temperate grassland following urine amendment
TL;DR: The first terrestrial source values of N( 2)O isotopomers are presented and it is confirmed that the enhanced tropospheric N(2)O site preference value could be the result of the back injection from the stratosphere.

Dolomitization of Atolls by Sea Water Convection Flow: Test of a Hypothesis at Niue, South Pacific
Paul Aharon,R. A. Socki,Lui Chan +2 more
TL;DR: In this article, a model of sea water convection is proposed for atoll dolomitization on the basis of a thermal gradient between the atoll and the ambient ocean water.
Journal ArticleDOI
Water-CO2 exchange set-up for the routine 18oxygen assay of natural waters.
TL;DR: The standard reproducibility of sample preparation is better than ±0·3 per mille and no difference in isotopic composition to that of samples prepared in the classical manner has been detected.

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.
