Scientists have developed a powerful new way to trace the journey of water across the planet by reading tiny atomic clues hidden inside it. Slightly heavier versions of hydrogen and oxygen, called ...

The isotopic compositions of hydrocarbon compounds are like a fingerprint. They can clearly indicate the way in which hydrocarbons like methane, ethane, propane, butane and pentane are formed. When ...

Stable isotopes in precipitation are important indicators for studying changes in the earth's water cycle and reconstructing the paleoclimate history. Previous studies have shown that the ...

Hydrocarbons, which are an essential component of crude oil and natural gas, form under pressure and high temperatures in the deep ocean floor. In the Guaymas Basin in the Gulf of California, ...
