Biogeochemistry: Less nickel for more oxygen
Mak A. Saito1
Abstract
The availability (or lack) of oceanic trace elements is providing fresh lines of explanation for turning points in Earth's history — the Great Oxidation Event being one such momentous occasion.
About 2.4 billion years ago, the oxygen content of Earth's atmosphere increased in what is called the Great Oxidation Event (GOE).
