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:

Isotopic fractionation and the quantification of 17O anomalies in the oxygen three-isotope system: an appraisal and geochemical significance
TL;DR: In this article, the relationship between δ17O and δ18O for entity a measured with respect to reference b is accurately represented by the linear function: 1000 ln 1+ δ 17 O 1000 =λ1000 ln [1+k a,b ](α 18/16 ) λ where ka,b is a measure of the offset (if any) of a from the mass-dependent fractionation line, of slope on which b lies.

Microfossil Assemblages and the Cenomanian-Turonian (late Cretaceous) Oceanic Anoxic Event
Ian Jarvis,G.A. Carson,M. K. E. Cooper,Malcolm B. Hart,Paul N. Leary,Bruce A. Tocher,D. Horne,A. Rosenfeld +7 more
TL;DR: The effects of the Cenomanian-Turonian Oceanic Anoxic Event (OAE) in the Chalk Sea of NW Europe have been investigated using published macrofossil records combined with new detailed sedimentological, foraminiferal, ostracod, calcareous nannofossil, dinoflagellate cyst and stable-isotope data from Dover, England as mentioned in this paper.
Book
An introduction to the chemistry of the sea
TL;DR: The authors provides students with an accessible introduction to marine chemistry, highlighting geochemical interactions between the ocean, solid earth, atmosphere and climate, enabling students to appreciate the interconnectedness of Earth's processes and systems and elucidates the huge variations in the oceans' chemical environment, from surface waters to deep water.
Journal ArticleDOI
Measurement of O18O16 ratios of total oxygen of carbonates
TL;DR: The commonly used phosphoric acid procedure for the determination of oxygen isotope abundances in carbonates involves a large kinetic isotope effect as mentioned in this paper, which leads to an overestimate of the dolomite-calcite oxygon isotope fractionation by 0.8 per mil.
Journal ArticleDOI
The marine oxygen isotope record in Pleistocene coral, Barbados, West Indies☆
TL;DR: The reef-crest coral Acropora palmata from late Pleistocene reefs on Barbados has recorded the same global variations in oxygen isotopes as planktonic and benthonic foraminifera as discussed by the authors.

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.
