Prediction of Sea Level Change around Australia and its Calibration and Validation by Satellite-Geodetic Measurements. The redistribution of mass and loading due to deglaciation will change the gravity field, spin axis and centre of mass of the Earth. As such, global sea level will not rise by the same amount in all places, and will even fall in some. This project will extend our realistic Earth model, constructed from a previous ARC grant, to simulate such changes in sea level. These simulat ....Prediction of Sea Level Change around Australia and its Calibration and Validation by Satellite-Geodetic Measurements. The redistribution of mass and loading due to deglaciation will change the gravity field, spin axis and centre of mass of the Earth. As such, global sea level will not rise by the same amount in all places, and will even fall in some. This project will extend our realistic Earth model, constructed from a previous ARC grant, to simulate such changes in sea level. These simulated values will be compared with contemporary estimates of ice mass balance and temporal gravity changes measured by satellite geodesy. Ultimately, this will allow for more informed management of sea level change in Australasia.Read moreRead less
The Integration of Built and Natural Environmental Datasets in National Spatial Data Infrastructure Initiatives. Delivering sustainable development nationally assumes knowledge about the natural and built environment. This requires access to data about these two environments which is facilitated by establishing a National Spatial Data Infrastructure (NSDI).

Delivering sustainable development nationally assumes knowledge about the natural and built environment. This requires access to data about these two environments which is facilitated by establishing a National Spatial Data Infrastructure (NSDI). The problem in Australia is that the states are the custodians of large to medium built and natural datasets while the Federal Government is the custodian of small scale natural datasets. While Australia has seen some success, the integration of these datasets is hampered by jurisdictional, institutional, administrative and legal issues. This research will investigate the differences in these forms of data and the justification and policy framework to integrate them in a NSDI.Read moreRead less

A multi-frequency microwave radiometer system for environmental research: A new capability for airborne remote sensing of key environmental variables will be established. The unique P-, Ku- and Ka-band passive microwave radiometer system will provide information on soil moisture, surface temperature and vegetation, and allow for a new satellite concept to be demonstrated. By combining with an existing L-band radiometer, data can be collected simultaneously at P-, L-, Ku- and Ka-bands, with increased spatial resolutions accordingly. The shorter wavelength, but higher spatial resolution data can be used to enhance the spatial resolution of the longer wavelength data, resulting in a capability to derive long wavelength observations from space at unprecedented spatial resolution.Read moreRead less

A long-term soil moisture record for Australia is critical to understanding climate change feedback mechanisms and their impacts on water management. This project will validate, downscale and harmonise soil moisture retrievals from three satellite missions across this decade, each using a new and different low resolution antenna technology and interpretation approach. Moisture Monitor, the framework to deliver this soil moisture record, will be verified using airborne campaigns and hydrological monitoring infrastructure in the Murrumbidgee catchment. Important outcomes will be validation of a new soil moisture satellite and development of a high resolution soil moisture product for improved land and water management and policy for Australia.Read moreRead less

Interferometric Synthetic Aperture Radar (InSAR) can be used to monitor ground deformation at high spatial resolution. When integrated with Global Positioning Systems (GPS) so that atmospheric disturbance in InSAR result can be corrected, deformation can be resolved at sub-centimetre accuracy. The corrected InSAR result can be exported as a data layer into Geographic Information Systems (GIS) for further analysis. In collaboration with Hong Kong Polytechnic University researchers, the integrated InSAR-GPS-GIS system will be tested in both Hong Kong and Australia. The expected outcomes include a suite of algorithms and software tools capable of operational, cost-effective ground deformation monitoring.Read moreRead less
Protecting Critical Transport Infrastructure using Hybrid Approaches for Interference and Spoofer Detection and Localisation. Modern infrastructure increasingly relies on the positioning and timing capabilities provided by the Global Navigation Satellite Systems (GNSS). GNSS signals, however, are vulnerable to interference and spoofing attacks. This vulnerability is aggravated as satellite navigation becomes more central to the operation of airports, ports, railways, and communications systems. ....Protecting Critical Transport Infrastructure using Hybrid Approaches for Interference and Spoofer Detection and Localisation. Modern infrastructure increasingly relies on the positioning and timing capabilities provided by the Global Navigation Satellite Systems (GNSS). GNSS signals, however, are vulnerable to interference and spoofing attacks. This vulnerability is aggravated as satellite navigation becomes more central to the operation of airports, ports, railways, and communications systems. Building on from earlier work by University of New South Wales, University of Adelaide and GPSat Systems, this project aims to create a system for locating interference and spoofers to GNSS of any power in real time, providing layered monitoring and reactive mitigation solutions against interference and spoofing attacks.Read moreRead less
Caught in a vice: Modelling crustal deformation in Papua New Guinea. Papua New Guinea is trapped between the collision of the Australian and Pacific Plates. This proposal uses GPS methods to measure and model the tectonic motion across Papua New Guinea, identifies and quantifies areas undergoing regional deformation near plate boundaries and within tectonic blocks, and evaluates the tectonic processes associated with such deformation. Numerical models will be developed to match the observed site ....Caught in a vice: Modelling crustal deformation in Papua New Guinea. Papua New Guinea is trapped between the collision of the Australian and Pacific Plates. This proposal uses GPS methods to measure and model the tectonic motion across Papua New Guinea, identifies and quantifies areas undergoing regional deformation near plate boundaries and within tectonic blocks, and evaluates the tectonic processes associated with such deformation. Numerical models will be developed to match the observed site motions, thereby revealing the nature of the active plate boundaries and the characteristics of the Earth's crust and mantle. The project will produce new results necessary for assessing the tectonic hazards of Papua New Guinea.

Due to the vast expense and difficulties to access many areas from the ground, there is currently no effective system for assessing and managing water resources over many large semi-arid regions of the world. Through the study of two complementary Basins - The Murray and Lake Chad Basins - we propose a new approach based on satellite imagery to provide regular and detailed information on the state of our water resources in these areas. These innovative techniques will yield new information on critical water issues: water availability, salinity, groundwater/surface water interactions, climate and land use change impact. This project provides the basis for sustainable water use in regional Australia.Read moreRead less

Effectively managing water resources within Australia is critical for social and economic growth. The large-scale of Australian catchments means that many lakes are unmonitored due to time and costs required for on-ground programs. This research project directly addresses the lack of observations. Information on water quality from satellite, on-ground, and modeling investigations are integrated to develop an operational monitoring system for surface water quality. Results are used to model the sensitivity of the water quality to changes in climate and land use. The monitoring system can be used to protect catchment assets by risk assessment and provide insights into management scenarios.Read moreRead less
