Tracking the global dynamics of Earth’s oxygen and biological production in deep time

In an article published online in PNAS Tuesday Sep 10th, we have demonstrated how a combination of metal isotope analyses in marine sedimentary rocks can constrain the global scale feedbacks between atmospheric oxygen, seafloor oxygenation, and marine biological production. The relationship between O2 and animal life turns out to be more entangled than first thought. […]
