In recent years, stable isotopes of the water molecule (oxygen-18 and deuterium) have become a useful tool for tracking the water cycle. The concentration of these tracers changes with variations of water molecules within the water cycle.

Oxygen isotope ecology of recent planktic foraminifera at the central Walvis Ridge (SE Atlantic) [PDF]
Above the Walvis Ridge, in the SE Atlantic Ocean, we collected living plantkic foraminifera from the upper water column using depth stratified plantkon tows. The oxygen isotope composition (

Stable and radiogenic isotopes as tracers for soil degradation [PDF]
Soil erosion seriously threatens mountain slopes. Direct measurement of soil erosion in the field is difficult and needs long term recording. However, stable and radiogenic isotopes are potential tracers for soil erosion estimation and would enable a ...

Oxygen isotopes of waters from the Coorong Lagoon, South Australia, from 2016-2018
To assess the fractionation of oxygen isotopes into the bivalve species Arthritica helmsi, live bivalve shells were collected alongside the waters in which they inhabit.

Isotopic Fingerprinting: A Promising Tool for Coffee Authenticity Checks
Almost every physical or chemical process in nature favors certain light stable isotopes over others, and thereby leaves an isotopic “fingerprint” on the substances involved.

Subbarrier interactions of the oxygen isotopes [PDF]
We derive a unified description of the low-energy elastic, inelastic, neutron transfer, and fusion cross sections of systems involving two stable oxygen isotopes. Coupled channels equations with an incoming wave boundary condition are employed, as is the no-recoil approximation; the adiabatic approximation, which violates unitarity, is avoided.

Nitrate pollution in surface water has become an environmental problem of global concern. The effective way for controlling the nitrate pollution of surface water is to identify the pollution source and reduce the input of nitrate.

It has been well reported that earthquakes can cause changes in groundwater chemistry and isotopes, and much of those changes were occurred in wells or hot springs; however, changes in cold spring caused by local small earthquakes have received less ...

Research on the Identification of Matheran Wine Region in the East Foot of Helan Mountain
Objective: To explore the feasibility of using stable carbon and oxygen isotopes and mineral elements in small-scale regional wine production identification, the fractionation characteristics of stable isotopes of carbon and oxygen in wine of Matheran ...
