A climate threshold for ocean deoxygenation during the Early Cretaceous

Nature, Published online: 04 September 2024; doi:10.1038/s41586-024-07876-1

Rapid ocean deoxygenation during the Early Cretaceous OAE1a is shown to provide evidence for a strong link between volcanic CO2 emissions, weathering and ocean oxygen content that is characterized by a climate threshold.
