The formation of the continents has been obscured by billions of years of history. It has been proposed that the Ontong Java Plateau is a modern day analogue for the continents. The Ontong Java Plateau is a huge submerged volcanic edifice, half the size of Australia. This project will seismically image the interior of the Earth beneath the Ontong Java Plateau and use these images as constraints to develop a model for its origin and evolution. This work has implications for understanding the formation of the continents and the factors that have enabled their stability for billions of years. A better understanding of continent formation may benefit Australia by yielding insights into economic resources, plate tectonics and geohazards.

大陆的形成被数十亿年的历史所掩盖。有人提出，翁通爪哇高原是现代大陆的类似物。Ontong Java Plateau是一个巨大的水下火山建筑物，面积相当于澳大利亚的一半。该项目将对Ontong Java高原下的地球内部进行地震成像，并利用这些图像作为约束条件，开发其起源和演变的模型。这项工作对于理解大陆的形成以及使其稳定数十亿年的因素具有重要意义。更好地了解大陆的形成可能会使澳大利亚受益，因为它可以深入了解经济资源、板块构造和地质灾害。
