Summary
GeoWulf: An Inference Engine for Complex Earth Systems. The project is to build a `Beowulf' cluster as a platform for solving
complex data inference problems in the Earth sciences, and in
particular the fields of thermochronology, seismology, crustal and
mantle dynamics, and landform evolution. A Beowulf cluster is a
network-linked set of commonly available `off-the-shelf' PC-computers
configured to give unprecedented performance/cost ratio. Projects

network-linked set of commonly available `off-the-shelf' PC-computers
configured to give unprecedented performance/cost ratio. Projects
using the Beowulf facility will combine state-of-the-art computational
techniques recently developed at ANU, and high quality data sets
collected over the past decade to address fundamental questions in
the Geosciences.Read moreRead less
The dynamic strength of continents and how they break apart. Sedimentary basins formed as a result of continental extension are the source of many oil and gas and geothermal resources. The geometries of the deepest part of these basins and their temporal and thermal evolution, are essential for basin prospectivity, but can seldom be investigated directly. This Australia-based project is expected to overhaul how we understand continental deformation, which is a crucial, but relatively vaguely und ....The dynamic strength of continents and how they break apart. Sedimentary basins formed as a result of continental extension are the source of many oil and gas and geothermal resources. The geometries of the deepest part of these basins and their temporal and thermal evolution, are essential for basin prospectivity, but can seldom be investigated directly. This Australia-based project is expected to overhaul how we understand continental deformation, which is a crucial, but relatively vaguely understood, component of plate tectonics. By modelling continental extension, the project will improve our understanding of basin development, deep geometry, and heat distribution, providing the basis for new applied and specific research projects directed at enhancing energy resource exploration.

The eruption, emplacement and characteristics of extremely large volume pyroclastic flow deposits (ignimbrites). Pyroclastic flows are hot, turbulent, flows of volcanic gas, pumice, rock debris and fine ash often produced during major explosive volcanic eruptions. Most historic and researched events have been mostly small volume examples. In this research we propose to investigate the characteristics of 3 extremely large volume (>1,000 km3) pyroclastic flow deposits in the Andes of South America ....The eruption, emplacement and characteristics of extremely large volume pyroclastic flow deposits (ignimbrites). Pyroclastic flows are hot, turbulent, flows of volcanic gas, pumice, rock debris and fine ash often produced during major explosive volcanic eruptions. Most historic and researched events have been mostly small volume examples. In this research we propose to investigate the characteristics of 3 extremely large volume (>1,000 km3) pyroclastic flow deposits in the Andes of South America, to understand the eruption origins and the flow dynamics of such large volume and potentially far flowing (up to 200 km from the vent) pyroclastic flows. These are potentially more destructive than the Indian Ocean tsunami event, and eruptions of this magnitude could occur in Indonesia, PNG and New Zealand.Read moreRead less
Neotectonics of the Indo-Australian plate. This project will contribute fundamental insights into the dynamics of our planet, towards earthquake risk assessment and to evolution of Australia's distinctive landscapes. The benefit of this project can therefore be evaluated in light of its contribution to the social and economic repercussions of improved understanding of earthquake risk and our landscapes and our place in them.
Volcanology of voluminous felsic lavas. Eruptions of voluminous lavas (>100km3)have occurred throughout geological time but not in recorded human history. These lavas are a major part of very large volcanic areas that form the continents. Excellent examples have been identified in the Gawler Range Volcanics, South Australia. Little is known about the eruption mechanisms and yet these events are the key to understanding large-scale melting processes deep in the Earth and continent formation. This ....Volcanology of voluminous felsic lavas. Eruptions of voluminous lavas (>100km3)have occurred throughout geological time but not in recorded human history. These lavas are a major part of very large volcanic areas that form the continents. Excellent examples have been identified in the Gawler Range Volcanics, South Australia. Little is known about the eruption mechanisms and yet these events are the key to understanding large-scale melting processes deep in the Earth and continent formation. This research will use field data from one of the South Australian examples to constrain the nature and position of the source volcanic centre and to clarify outflow mechanisms.Read moreRead less
Megafauna and mega-extinction: assessing palaeocommunity change using dental complexity and shape analyses. This research will address an important issue of national interest - the causes of the extinction of the Australian megafauna. By furthering research on the causes of this historic event, valuable insights will be gained into possible causes of current extinction events and the future impact of climate change. It will bring to Australia new technologies and methods developed overseas by an ....Megafauna and mega-extinction: assessing palaeocommunity change using dental complexity and shape analyses. This research will address an important issue of national interest - the causes of the extinction of the Australian megafauna. By furthering research on the causes of this historic event, valuable insights will be gained into possible causes of current extinction events and the future impact of climate change. It will bring to Australia new technologies and methods developed overseas by an Australian researcher, and put Australia at the forefront of several areas of research including 3D scanning and analysis. This project will form part of an international collaboration called the MorphoBrowser, an exciting advance in the study of biological diversity. This will help maintain Australia as a pre-eminent country for palaeontology research.Read moreRead less
Wave-ice models of Antarctic sea ice. This project aims to design and execute autonomous observations above (unmanned aerial vehicles), below (autonomous underwater vehicles) and within (wave-ice interaction buoys) sea ice on international Antarctic research voyages. The project intends to advance the parameterisation of wave-ice interaction, critical to the seasonal advance and retreat of Antarctic sea ice, in climate models that do not reproduce the observed trends in regional Antarctic sea ic ....Wave-ice models of Antarctic sea ice. This project aims to design and execute autonomous observations above (unmanned aerial vehicles), below (autonomous underwater vehicles) and within (wave-ice interaction buoys) sea ice on international Antarctic research voyages. The project intends to advance the parameterisation of wave-ice interaction, critical to the seasonal advance and retreat of Antarctic sea ice, in climate models that do not reproduce the observed trends in regional Antarctic sea ice extent. The project expects to improve prediction of sea ice’s responses and feedbacks to changes in ocean and atmospheric forcing around the Southern Ocean. This work should place Australia at the forefront of polar climate research. Greater accuracy in climate projections will help to optimise the balance between human populations, economic growth and environmental protection in an uncertain future.Read moreRead less

This research will examine the south eastern tectonic plate boundary of Australia, providing analogues for seafloor spreading related crustal processes that relate to present plate boundaries and ancient examples now joined to the Australian continent. The scientific innovation represented by this project will help Australian scientists to better understand an important part of the plate tectonic cycle. This project will be of direct relevance to the Australian minerals exploration industry and will provide better constraints on rift-related metallogenesis.Read moreRead less
Quantifying the Phanerozoic thermal evolution and long-term stability of cratonic lithosphere using integrated low temperature thermochronology. The Earth's most ancient crustal regions (i.e. cratons) are thought to have remained remarkably stable since their formation >2.5 billion years ago. This project will re-evaluate this paradigm by applying low temperature thermochronology by the fission track and (U-Th)/He methods to three key cratons, to detect and quantify previously unknown episodes o ....Quantifying the Phanerozoic thermal evolution and long-term stability of cratonic lithosphere using integrated low temperature thermochronology. The Earth's most ancient crustal regions (i.e. cratons) are thought to have remained remarkably stable since their formation >2.5 billion years ago. This project will re-evaluate this paradigm by applying low temperature thermochronology by the fission track and (U-Th)/He methods to three key cratons, to detect and quantify previously unknown episodes of significant cooling and denudation (i.e. low-level instability) which are invisible to other analytical techniques. The outcomes will open a new research avenue in these terrains, which host some of the world's most valuable mineral resources, underlie important petroleum basins and are potential long-term repositories for radioactive waste.
