Water is made of hydrogen and oxygen, and sometimes these atoms are slightly heavier than usual. These heavier forms are called isotopes. As water evaporates or moves through the atmosphere, the ...

Archaeologists at UC Santa Cruz used predictive modeling to map strontium isotope ratios across all of modern-day Angola, a region in Southwest Africa that was once a major hub for the transatlantic ...

The continental volcanism, oceanic volcanism and mid-ocean ridge volcanism emit Hg to the atmosphere and ocean. Mercury in atmosphere deposit to aquatic and terrestrial systems via wet or dry ...
