Building the thermodynamic framework for modelling the Earth
Grant number: DP0987731 | Funding period: 2009 - 2014
The Earth holds resources essential for society, such as metals and petroleum, but it also presents risks to society, such as earthquakes and volcanoes. To understand these, we need to understand how the Earth works, and not just at or close to the Earth's surface where these things are found or are felt. This fellowship aims to provide the framework and the tools for modelling the processes involved in how the Earth works. Such tools will, for example, dramatically improve our ability to understand, and therefore to find, ore deposits.
