Understanding the Geodynamo: Putting Australia on the Map

This Project aims to construct high-quality Australian palaeomagnetic records from lake sediments for incorporation into models of Earths magnetic field history. Earths magnetic field is generated by a dynamo within our planets outer core, it underpins modern navigation and forms a shield against space radiation. International efforts to understand ancient geodynamo evolution lack Australian palaeomagnetic data, a shortcoming referred to as the Australian data wasteland. This Project aims to address this data deficiency and is expected to reinvigorate Australias role in understanding the geodynamo. Furthermore, models of Earths ancient magnetic field are anticipated to provide ages for Australian archaeological and climate records.
