New publication: Sustained increases in atmospheric oxygen and marine productivity in the Neoproterozoic and Palaeozoic eras

New publication: Sustained increases in atmospheric oxygen and marine productivity in the Neoproterozoic and Palaeozoic eras

July 2, 2024By Tais W DahlUncategorized

In 2010, we published an influential paper in PNAS based on molybdenum isotopes in euxinic shales to suggesting Earth’s oxygen level increased in two steps during the rise of animals and rise of land plants. Now, 14 years later, geochemists have collected far more geochemical data from the geological rock record and developed better models … Read More

New study: The Earth system can tip into a state of global marine anoxia

New study: The Earth system can tip into a state of global marine anoxia

June 24, 2024By Tais W DahlPublication, Research

In a new study published in One Earth (Cell Press), Aske L. Sørensen and Tais W. Dahl demonstrates that the Earth system tipped into a state of widespread marine anoxia during the Cambrian SPICE event. A self-cascading mechanism involving anoxia-dependent nutrient release from seafloor sediments has been documented regionally and hypothesized to operate globally. The … Read More
