THE OXYGENATION OF EARTH'S EARLY MARINE ECOSYSTEMS
Grant number: DE190100988 | Funding period: 2019 - 2022
This project aims to map out the complex evolution of the Earth’s ocean ecosystems and oxygenation using marine carbonates. The oxygenation of Earth’s surface is one of the most profound processes to shape the planet, affecting all biological and geological systems. However, uncertainties remain in the timing of oxygenation and how it relates to the evolution of life. This project will develop our understanding of how Earth has remained habitable through significant intervals of environmental change. Using the geology of Australia, and elsewhere, this project is expected to derive the oxygenation evolution of ancient seawater and its effect on reef ecosystems during critical intervals of Ear..View full description
