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:

Reconstruction of the paleoenvironmental changes around the Miocene–Pliocene boundary along a West–East transect across the Mediterranean
Catherine Pierre,Antonio Caruso,Marie-Madeleine Blanc-Valleron,Jean Marie Rouchy,Fabienne Orzsag-Sperber +4 more
TL;DR: In order to reconstruct the environmental changes at the end of the Messinian salinity crisis, a multidisciplinary study has been carried out with a high sampling resolution of the late Messinian-early Zanclean (Zone MPl 1) sediments along a West-East Mediterranean transect.

Mercury concentrations in landlocked Arctic char (Salvelinus alpinus) from the Canadian Arctic. Part I: Insights from trophic relationships in 18 lakes
Nikolaus Gantner,Nikolaus Gantner,Michael Power,Deborah Iqaluk,Markus Meili,Hans Borg,Marcus Sundbom,Keith R. Solomon,Greg Lawson,Derek C G Muir,Derek C G Muir +10 more
TL;DR: Results indicate that TMFs and food chain length (FCL) are key factors in explaining interlake variability in biomagnification of [Hg] among different lakes.
Journal ArticleDOI
Stable isotope ratios of dissolved inorganic carbon in the Atlantic
W.G. Deuser,J.M. Hunt +1 more
TL;DR: In this paper, a correlation between the concentration of dissolved oxygen and δ 13C is observed at all stations below the top meters, due to the oxidation of organic matter depleted in 13C.

Quantifying water sources to a semiarid riparian ecosystem, San Pedro River, Arizona
Matthew N. Baillie,Matthew N. Baillie,James F. Hogan,Brenda Ekwurzel,Arun K. Wahi,Christopher J. Eastoe +5 more
TL;DR: In this article, the authors investigated the contribution of different water sources (e.g., local recharge during monsoon flood events versus inflow of basin groundwater) to riparian groundwater and river baseflow in the Upper San Pedro River Basin.

Deep circulation in the Late Cretaceous: Oxygen isotope paleotemperatures from Inoceramus remains in D.S.D.P. cores
TL;DR: Inoceramus is an epibenthic bivalve which lived in a wide variety of paleoenvironments encompassing a broad range of paleodepths as mentioned in this paper.

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.
