This project aims to address critical unsolved problems in global geophysics by probing the structure and dynamics of the inner core, the Earth’s time capsule. It focuses on elucidating the inner core’s nature with the improved tomographic images, critically testing our current understanding of how the inner core is assembled and grows, its thermodynamic state, crystallographic structure, and connection with the Earth’s upper layers and geomagnetic field. Answering these questions can have far-reaching consequences for the current knowledge of fundamental geophysics. Expected benefits include training students and researchers in geophysics and data processing, contributing to a skilled STEM workforce and creating leadership for Australia.

该项目的目的是通过探测地球的时间胶囊内核的结构和动力学，解决全球地球物理学中尚未解决的关键问题。它的重点是阐明内核的性质与改进的断层图像，严格测试我们目前的理解如何内核是组装和增长，其热力学状态，晶体结构，并与地球的上层和地磁场的连接。对这些问题的探讨可能会对基础物理学的现有知识产生深远的影响。预期的好处包括培训学生和研究人员在物理学和数据处理，有助于熟练的STEM劳动力和创造澳大利亚的领导地位。
