Phosphorus spikes linked to ancient marine mass extinctions

Researchers have uncovered new evidence that short-lived spikes in ocean phosphorus may have played a major role in two of the most severe marine extinctions in Earth's history. Dr. Matthew Dodd from The University of Western Australia's School of Earth and Oceans is lead author of the study published in Nature Communications, which sheds new light on how nutrient disruption can destabilize life, climate, and ocean chemistry on a global scale.
