Stable isotope analysis has become an indispensable tool in deciphering the complexities of the water cycle and climate variability. By measuring the ratios of stable isotopes such as δ18O and δ2H in ...

Sixty years ago, the very first samples of rainwater were collected for the Global Network of Isotopes in Precipitation (GNIP), while the science of isotope hydrology was still taking its first steps.

This publication is a result of the Coordinated Research Project (CRP) F32008 "Global Monitoring of Nitrogen Isotopes in Atmospheric Waters" implemented by the IAEA’s Isotope Hydrology Section in 2018 ...

Scientists have used clues locked into tree rings to reveal major changes in the Amazon's rainfall cycle over the last 40 years: wet seasons are getting wetter and dry seasons drier. Oxygen isotope ...

Quantifying ecosystem respiration remains challenging in aquatic ecosystems. Most investigators assume that nighttime and daytime respiration are equal. Recent studies suggest measuring dissolved ...

Corals and cave carbonates can reveal the temperatures that prevailed at the Earth's surface at the time they formed. An international team of geoscientists has developed a new method that makes it ...

CORVALLIS, Ore. – At times in the distant past, an abrupt change in climate has been associated with a shift of seasonal monsoons to the south, a new study concludes, causing more rain to fall over ...
