Oxygenation history of the Earth and the evolution of complex life. This project will investigate how and when the atmosphere became oxygen-rich by analyzing ancient barrier reefs and other rocks that formed between 1000 to 300 million years ago, spanning the appearance and diversification of animals and plants. The project is significant because the buildup of oxygen in the atmosphere was arguably the most important chemical process ever to have occurred on Earth and controlled the evolution of ....Oxygenation history of the Earth and the evolution of complex life. This project will investigate how and when the atmosphere became oxygen-rich by analyzing ancient barrier reefs and other rocks that formed between 1000 to 300 million years ago, spanning the appearance and diversification of animals and plants. The project is significant because the buildup of oxygen in the atmosphere was arguably the most important chemical process ever to have occurred on Earth and controlled the evolution of environments, climate and life. A major outcome will be an improved understanding of how the Earth's atmosphere and climate are regulated by geological processes. This project will generate new knowledge about how sedimentary zinc, lead and copper ore deposits form, which may guide exploration for these commodities.Read moreRead less

Summary
The oxygenation of Earth’s early marine ecosystems. 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 habitab ....The oxygenation of Earth’s early marine ecosystems. 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 Earth’s history.Read moreRead less
