Active Ice-Shelf Rift Systems on the Amery Ice Shelf, East Antarctica. Our work will inform the public on how the Antarctic might contribute to global sea level rise, e.g., are current iceberg production rates accelerating and causing inland ice to flow into the sea more rapidly? Furthermore, a greater understanding of the important Earth systems, including the ocean-ice-atmosphere system, is important to a society contemplating the responsibilities of stewardship of the planet as we move into t ....Active Ice-Shelf Rift Systems on the Amery Ice Shelf, East Antarctica.

Furthermore, a greater understanding of the important Earth systems, including the ocean-ice-atmosphere system, is important to a society contemplating the responsibilities of stewardship of the planet as we move into the era of potentially profound effects from global climate change.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
Tracking the response of terrestrial and ocean waters to climate variations using space gravity observations. Climate change puts Australia at risk from sea level rise and an increase in the occurrence and intensity of droughts. We need to learn about issues concerning the water cycle that are still poorly understood, such as whether droughts cause a reduction in only surface water or also water stored in underground reservoirs and what happens to ocean waters when thermal expansion causes an in ....Tracking the response of terrestrial and ocean waters to climate variations using space gravity observations. Climate change puts Australia at risk from sea level rise and an increase in the occurrence and intensity of droughts. We need to learn about issues concerning the water cycle that are still poorly understood, such as whether droughts cause a reduction in only surface water or also water stored in underground reservoirs and what happens to ocean waters when thermal expansion causes an increase in sea surface height in some regions but not others. This proposal will provide new and accurate scientific information on the risks of sea level rise through the effects of thermal expansion of the oceans, in particular in shallow coastal zones. It will help us to understand droughts, variations in water resources and groundwater recharge patterns.Read moreRead less
