The three most stable isotopes of hydrogen: protium (A = 1), deuterium (A = 2), and tritium (A = 3).

An introduction to the stable H- and O-isotopes, their spatial distribution, and what they are good for. Background information specific to WaterIsotopes.org content.

Jan 31, 2022 · Water isotopes refer to atoms of oxygen (O) and hydrogen (H) in water molecules (H 2 O) that have slightly different atomic masses due to different numbers of neutrons in their …

Water consists of two hydrogen atoms and one oxygen atom – H2O. At first thought, it would seem there should only be one kind of water. This is not accurate, however. That is so …

Two stable isotopes of hydrogen (1 H and 2 H) and three of oxygen (16 O, 17 O and 18 O) occur naturally in waters and in biological and geological materials. Of these, 1 H, 2 H, 16 O and 18 …

The most commonly used isotope application in hydrology uses hydrogen and oxygen isotopes to evaluate sources or age of water, ice or snow. Isotopes in ice cores help to reveal conditions …

Hydrogen has three naturally occurring isotopes, denoted 1 H, 2 H and 3 H. Other, highly unstable nuclei ( 4 H to 7 H) have been synthesized in the laboratory but are not observed in nature. 1 …

Mar 5, 2025 · Water availability is controlled by processes that can be hard to measure, like the process of groundwater discharging from a streambed that becomes streamflow. Naturally …

Mar 31, 2020 · This article provides an overview of the use of stable isotopes to analyze (i) groundwater recharge from both rainfall and irrigation water, and presents case studies that …

May 16, 2023 · The stable isotope ratios of oxygen and hydrogen in water provide a unique opportunity to evaluate hydrological processes and investigate their role in the variability of the …
