Enhancing marine bathymetry using new generation satellite sensors. Highly accurate marine bathymetry are currently lacking in 72% of the global ocean including around Australia, particularly in shallow seas and near-shore coastal zones, contributing to various navigation and marine safety accidents. Ship surveys of the seafloor are time-consuming and expensive. Satellite altimetry data provide an alternative solution. This project will improve Australia’s marine bathymetry by using spatially co ....Enhancing marine bathymetry using new generation satellite sensors. Highly accurate marine bathymetry are currently lacking in 72% of the global ocean including around Australia, particularly in shallow seas and near-shore coastal zones, contributing to various navigation and marine safety accidents. Ship surveys of the seafloor are time-consuming and expensive. Satellite altimetry data provide an alternative solution. This project will improve Australia’s marine bathymetry by using spatially comprehensive and unprecedented data from new radar and laser satellite sensors. We aim to develop techniques for integration of the new data with other independent data sources, producing the most precise marine bathymetry for coastal terrain mapping, marine transport and safety management.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
