Standard for Reporting Concentrations of Deuterium and Oxygen-18 in Natural Waters.
TLDR
A standard, based on the set of ocean water samples used by Epstein and Mayeda to obtain a reference standard for oxygen-18 data, but defined relative to the National Bureau of Standards isotopic reference water sample, is proposed for reporting both deuterium and oxygen- 18 variations in natural watersrelative to the same water.Abstract:
A standard, based on the set of ocean water samples used by Epstein and Mayeda to obtain a reference standard for oxygen-18 data, but defined relative to the National Bureau of Standards isotopic reference water sample, is proposed for reporting both deuterium and oxygen-18 variations in natural waters relative to the same water. The range of absolute concentrations of both isotopes in meteoric-waters is discussed.read more

Selected challenges in runoff generation research in forests from the hillslope to headwater drainage basin scale
TL;DR: In this paper, the authors focus on watershed watersheds to identify the most vulnerable areas to increased storm runoff and erosion in forest land management issues such as the impacts of logging or forest conversion to other land uses.

Recorders of reef environment histories: stable isotopes in corals, giant clams, and calcareous algae
TL;DR: Time series δ18O and δ13C records from cohabiting massive coralPorites australiensis and giant clamTridacna gigas from the Great Barrier Reed of Australia, and from calcareous green algae in a core through modernHalimeda bioherm accreting in the eastern Java Sea, provide insights into the complex links between environmental factors and stable isotopes imprinted in these reef skeletal materials as discussed by the authors.

Oxygen-18 variations in sulfate ions in sea water and saline lakes
A. Longinelli,Harmon Craig +1 more
TL;DR: A new method measures the oxygen-isotopic composition of dissolved sulfate ions and barium sulfate, finding that the value of the highest enrichment observed is about the same as that of atmospheric oxygen.

Oxygen isotope analysis in a land of environmental extremes: the complexities of isotopic work in the Andes
TL;DR: In this article, the advantages and disadvantages of oxygen isotope analysis in the Andes, and beyond, were explored using isotope data from archaeological human enamel and bone from Peru, Bolivia and Chile (c. AD 1-1500).

Carbon, hydrogen, and oxygen isotope studies of the regional metamorphic complex at Naxos, Greece
TL;DR: In this paper, a migmatite dome is surrounded by schists and marbles of decreasing metamorphic grade, and the δ18O values of silicate minerals and quartz segregations in marble-rich zones are usually very large and were controlled by exchange with the adjacent marbles.

Isotopic Variations in Meteoric Waters
TL;DR: The relationship between deuterium and oxygen-18 concentrations in natural meteoric waters from many parts of the world has been determined with a mass spectrometer and shows a linear correlation over the entire range for waters which have not undergone excessive evaporation.

Isotopic standards for carbon and oxygen and correction factors for mass-spectrometric analysis of carbon dioxide
TL;DR: 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.

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.

Effect of Low Concentrations of Carbon Dioxide on Photosynthesis Rates of Two Races of Oxyria.
TL;DR: Alpine plants of Oxyria digyna have higher apparent photosynthesis rates at various carbon dioxide concentrations than arctic, sea-level plants of the same species, which may be involved in the survival of plants at high elevations.
