ARC Linkage Project led by Prof. Miller and Prof. Kennett in collaboration with GSWA (Dr. Gessner and Dr. Murdie), Geoscience Australia (Dr. Allen), and Macquarie Uni (Dr. Yuan) and the Department of Fire and Emergency Services (Grey and Whitney) .  The project aims to produce new 3-D seismic velocity structure models of the southwest region of Australia with new data collected by a two-year deployment of 25 passive seismic recorders. In conjunction with previously collected geophysical datasets by our partners this project will allow the determination of structure in 3-D to lithospheric depths. The objective of this work is to provide a compilation of 3-D models of the crust and lithosphere, which will be an effective characterisation of the 3-D structure of the craton and its margins.

Nature of Project(s): Computational, fieldwork and numerical

Several projects exist to study continental lithospheric structure and formation from a seismological perspective. These projects are primarily computer based, and prior experience with python, Matlab or similar programs would be advantageous. Opportunities to assist in collecting seismic data in the field may also arise during the course of a project.
