This project will assess the utility of space and ground based gravity measurements for monitoring changes in the hydrological cycle at regional scales. At present there are no methods available for monitoring changes in terrestrial water storage over the globe, despite their importance for assessing the effects of large-scale changes in land use and climate change. The launch of NASA's Gravity Recovery and Climate Experiment satellites later this year provides a 5-year window of opportunity to undertake ground-based research to test this innovative technique for monitoring terrestrial water storage from gravity measurements - something that has been shown to be possible theoretically, but has not been testable until now.Read moreRead less
Environmental geodesy: variations of sea level and water storage in the Australian region. It is essential for Australia's long-term planning and security that the effects of global warming on our nation's water resources and coastlines are quantified. Sea level variations projected into the future vary around Australia and have large uncertainties, yet the impacts have substantial social and financial ramifications for our community. Australia hasn't yet quantified accurately its critical water ....Environmental geodesy: variations of sea level and water storage in the Australian region. It is essential for Australia's long-term planning and security that the effects of global warming on our nation's water resources and coastlines are quantified. Sea level variations projected into the future vary around Australia and have large uncertainties, yet the impacts have substantial social and financial ramifications for our community. Australia hasn't yet quantified accurately its critical water resources nor how they are changing. This proposal will address both these issues, providing for the first time valuable and accurate information for planning appropriate strategies to mitigate the impact of sea level rise and water storage on the Australian society.Read moreRead less
