Summary
Investigating the formation of the continents: Ontong Java Plateau as a modern day analogue. 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 develo ....Investigating the formation of the continents: Ontong Java Plateau as a modern day analogue. 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.Read moreRead less

Summary
Earth’s response to ice unloading: a unique GPS measurement from Antarctica . Earth's response to ice unloading - a unique GPS measurement from Antarctica: This project aims to deploy geophysical equipment including global navigation satellite systems within Antarctica to understand how Earth responds to changes in stress (rheology) within the crust and upper mantle (the upper ~660 km). It exploits a globally-unique natural experiment that commenced in 2002 with the break-up of the Larsen B Ice ....Earth’s response to ice unloading: a unique GPS measurement from Antarctica . Earth's response to ice unloading - a unique GPS measurement from Antarctica: This project aims to deploy geophysical equipment including global navigation satellite systems within Antarctica to understand how Earth responds to changes in stress (rheology) within the crust and upper mantle (the upper ~660 km). It exploits a globally-unique natural experiment that commenced in 2002 with the break-up of the Larsen B Ice Shelf and which was followed by large-scale ice-mass unloading and rapid surface deformation. New broadband passive seismic and geodetic deformation measurements offer the promise of resolving a dichotomy between laboratory and millennial-scale determinations of Earth rheology through uniquely studying a time-scale mid-way between these extremes, whilst further strengthening Australia's emerging expertise in polar geophysics.Read moreRead less
Establishing the reference frame using astronomical and space-geodetic observations. Australia is increasingly dependent on spatial positioning and spatial data, yet mostly relies upon international agencies and research organisations to provide regular updates of coordinates and reference frame definition used on Earth. Improving the accuracy of the reference frame definition and our understanding of errors in the space-based measurements will provide new insights for studies of the Earth.

Australia is increasingly dependent on spatial positioning and spatial data, yet mostly relies upon international agencies and research organisations to provide regular updates of coordinates and reference frame definition used on Earth. Improving the accuracy of the reference frame definition and our understanding of errors in the space-based measurements will provide new insights for studies of the Earth. The research will yield results in studies of national significance, such as sea level rise, the effects of melting polar regions, and crustal deformation, as well as developing Australia's expertise in exploiting observations of the Earth from space.Read moreRead less
