East Antarctica: subglacial heat flux constraints for ice sheet modelling. This project aims to quantify the heat flux from the East Antarctic continent into the base of the ice sheet via the derivation of a large geochemical database, together with elevation-based modelling and new heat flux measurements in regions formerly contiguous with East Antarctica. This subglacial heat flux is poorly constrained in current ice sheet models, but directly affects ice sheet behaviour. The output of this pr ....East Antarctica: subglacial heat flux constraints for ice sheet modelling. This project aims to quantify the heat flux from the East Antarctic continent into the base of the ice sheet via the derivation of a large geochemical database, together with elevation-based modelling and new heat flux measurements in regions formerly contiguous with East Antarctica. This subglacial heat flux is poorly constrained in current ice sheet models, but directly affects ice sheet behaviour. The output of this project will be a greatly improved heat flux map for East Antarctica that can be used in ice sheet modelling studies. This should drive significant improvement in models for the evolution of the East Antarctic Ice Sheet, resulting in more accurate projections of ice discharge and associated sea level change.Read moreRead less
How do sediments become magnetised? Construction of an empirical-numerical framework. The magnetism of sediments provides information on the past behaviour of the Earth's magnetic field. This project will study sediments from the oceans around Australia to understand how the field was recorded and use this information to construct a new generation of computer models that will provide insights into the physics of the recording process.
Gaining insights into mine waste dumps to avoid environmental legacies. The project aims to develop new methods for identifying pollution source hotspots and pathways inside mine waste rock dumps. This addresses the national need for effective management of Acid and Metalliferous Drainage (AMD), which is now a critical consideration in the viability of new mines and in confronting pollution legacies of old mines. The research will develop and test innovative methods of geophysical and geochemica ....Gaining insights into mine waste dumps to avoid environmental legacies. The project aims to develop new methods for identifying pollution source hotspots and pathways inside mine waste rock dumps. This addresses the national need for effective management of Acid and Metalliferous Drainage (AMD), which is now a critical consideration in the viability of new mines and in confronting pollution legacies of old mines. The research will develop and test innovative methods of geophysical and geochemical analysis and their integration that provide 3-dimensional mapping of key physical and chemical features of the dump. Expected outcomes include greater confidence in the ability of the mining industry to manage its AMD liability. Read moreRead less
