TLDR
The isotopic composition of precipitation and river runoff in the vicinity of the North American Great Lakes is characterized by a higher deuterium-excess value than observed in the advecting air masses as discussed by the authors.
Abstract
The isotopic composition of precipitation and river runoff in the vicinity of the North American Great Lakes is characterized by a higher deuterium-excess value than observed in the advecting air masses. It is suggested that this indicates that evaporated moisture from the surface waters is mixed with the atmosphere waters. A preliminary estimate of the atmospheric water balance during summer and autumn indicates that between 4.6%–15.7% of the atmospheric water content downwind from the Great Lakes is derived from lake evaporation during summer.

Oxygen and hydrogen isotopes in the hydrologic cycle

TL;DR: In this article, the isotope fractionations that accompany the evaporation from the ocean and other surface waters and the reverse process of rain formation account for the most notable changes.

Interpolating the isotopic composition of modern meteoric precipitation

TL;DR: In this paper, the accuracy of interpolated bD and δ 1 8 O estimates made using four methods is tested using resampling, and the best method lowers estimation error by 10-15% relative to others tested and gives an average error, using all available data, 2.5% of the global range.

Global application of stable hydrogen and oxygen isotopes to wildlife forensics.

TL;DR: The precipitation maps show that the greatest potential for applying hydrogen and oxygen isotope forensics exists in mid- to high-latitude continental regions, where strong spatial isotope gradients exist and where strong, mechanistic relationships link precipitation and isotope ratios in biological tissue exist.

Distribution of oxygen-18 and deuterium in river waters across the United States†

TL;DR: In this article, more than 4800, depth-and width-integrated, stream samples from 391 selected sites within the USGS National Stream Quality Accounting Network (NASQAN) and Hydrologic Benchmark Network (HBN) were analyzed for δ18O and δ2H (http://water.usgs.gov/pubs/ofr/Ofr/of r00-160/pdf/Of r00 -160.pdf).

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.

Global climatic interpretation of the deuterium‐oxygen 18 relationship for precipitation

TL;DR: In this paper, a theoretical model is derived to account for the deuterium-oxygen 18 relationship measured in meteoric waters, where a steady state regime is assumed for the evaporation of water at the ocean surface and the subsequent formation of precipitation.

Deuterium and oxygen 18 in precipitation: Modeling of the isotopic effects during snow formation

TL;DR: In this paper, the authors present a new model that takes into account the existence of an isotopic kinetic effect at snow formation as a result of the fact that vapor deposition occurs in an environment supersaturated over ice.
