This Project aims to construct high-quality Australian palaeomagnetic records from lake sediments for incorporation into models of Earth’s magnetic field history. Earth’s magnetic field is generated by a dynamo within our planet’s 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 Australia’s role in understanding the geodynamo. Furthermore, models of Earth’s ancient magnetic field are anticipated to provide ages for Australian archaeological and climate records.

该项目旨在从湖泊沉积物中构建高质量的澳大利亚古地磁记录，以纳入地球磁场历史模型。地球的磁场是由我们星球外核内的发电机产生的，它支撑着现代导航，并形成了一个抵御太空辐射的屏障。国际上了解古代地球发电机演化的努力缺乏澳大利亚的古地磁数据，这一缺陷被称为“澳大利亚数据荒地”。该项目旨在解决这一数据不足问题，并有望重振澳大利亚在了解地球发电机方面的作用。此外，地球古代磁场的模型预计将为澳大利亚考古和气候记录提供年龄。
