PAST EAST ANTARCTIC ICE SHEET AND GLOBAL SEA-LEVEL VARIATIONS. Unique fossil-bearing, open marine sediments occur inland from the modern Antarctic coastline. These were deposited when a now-glaciated Antarctic basin became a marine embayment, during intervals of significantly reduced ice sheet volume and elevated global sea-level in the past. Urgent palaeontological, sedimentological and geochemical research on these sediments are vital to provide: directly datable in situ evidence for major i ....PAST EAST ANTARCTIC ICE SHEET AND GLOBAL SEA-LEVEL VARIATIONS. Unique fossil-bearing, open marine sediments occur inland from the modern Antarctic coastline. These were deposited when a now-glaciated Antarctic basin became a marine embayment, during intervals of significantly reduced ice sheet volume and elevated global sea-level in the past. Urgent palaeontological, sedimentological and geochemical research on these sediments are vital to provide: directly datable in situ evidence for major ice sheet retreat and global sea-level rise in the past; and quantifiable data concerning the environment during such events; an innovative opportunity to improve predictions of Antarctica's response to global warming and answer international debate about past Antarctic Ice Sheet stability.Read moreRead less

Summary
The role of mantle plumes in driving plate tectonics and continental margin evolution. Plumes of molten rock rise from deep within the Earth resulting in massive surface eruptions that can lead to global mass extinction events. Despite their size, the role plumes play in driving movements of the continents is poorly understood. This project combines independent global and Australian geological and geophysical data with open software systems to link deep Earth and surface geological processes.

Plumes of molten rock rise from deep within the Earth resulting in massive surface eruptions that can lead to global mass extinction events. Despite their size, the role plumes play in driving movements of the continents is poorly understood. This project combines independent global and Australian geological and geophysical data with open software systems to link deep Earth and surface geological processes. This approach will result in a clearer understanding of how the internal workings of our planet drive, and interact with, surface geological processes. The project will also show how these interactions shape the environmentally important, and resources rich, continental margins and ocean basins.Read moreRead less

Australian Membership of the Integrated Ocean Drilling Program. Membership of the Integrated Ocean Drilling Program (IODP) will provide high-leverage access to the largest, and most effective international geoscience program.
Results from drilling within Australia's marine jurisdiction will give understanding of the oceans' state under past climates through high resolution records of the range of oceanographic and biological responses to climate change, the role of the deep biosphere in shapin ....Australian Membership of the Integrated Ocean Drilling Program. Membership of the Integrated Ocean Drilling Program (IODP) will provide high-leverage access to the largest, and most effective international geoscience program.
Results from drilling within Australia's marine jurisdiction will give understanding of the oceans' state under past climates through high resolution records of the range of oceanographic and biological responses to climate change, the role of the deep biosphere in shaping oil and gas deposits, hydrothermal and igneous processes involved in ore genesis, and enhanced understanding of some of the world's largest earthquake- and tsunami-generating processes.
