About the research project

The ‘critical zone’ is the outermost subsurface layer of our Earth.  In this zone, water interacts with weathered rock and/or loose sediments, and potentially with biological and chemically active material.  Such interactions can cause gradual or sudden failure, and other environmental impacts. In a changing climate, the critical zone is an important but hidden changing layer.  Critical zone investigations are of consequence for the fast-evolving field of planetary geophysics whereby the shallow surface beneath remote landers also provides a challenge for rapid characterisation.

This project will make use of geophysical methods such as seismology and electrical methods that have seen recent technological acceleration such that large numbers of cable-free sensors may be quickly deployed for fast data collection.  Multivariate statistical methods, including machine learning, are also enabling further datasets to be combined for an integrated understanding of the near-surface and how this is changing over time.  The project could focus on theoretical aspects of computer simulation, and/or field data collection and analysis, depending on the interests of the student researcher.  These approaches will lead to a greater understanding of how to detect and manage both gradual change and water ingress due to extreme events on Earth.  The approaches will also enable improved investigations of the shallow and deep interiors of planetary bodies.

Project outcomes will provide the basis of an expanded capability for Australia in detecting change in coastal environments and environments adjacent to other large water bodies.  Newly developed software and workflows will enable near-surface characterization to be rolled out to environmental and/or geotechnical and/or space-industry partners.
