Understanding the Deep Carbon Cycle from Icehouse to Greenhouse Climates

Sydney Research Excellence Initiative grant (2017-2018) Research area, key questions, significance, and innovation. The planet is experiencing a major transition from an icehouse climate, one dominated by permanent continental ice sheets at high latitudes, to a greenhouse climate that favours ice-free conditions. Although part of the deglaciation trend is influenced by a natural orbital cycle, … Read more…

Earth's climate throughout the Phanerozoic

Eocene topo bath

Eocene topo bathProject Summary
EarthByte is involved in a series of projects aimed at understanding and modeling Earth’s climate throughout the Phanerozoic. Some of these projects include:

  • Future Fellowship of Maria Seton on “Oceanic gateways: a primary control on global climate change?”
  • Basin GENESIS Hub activities, related to the effect of the mantle, crustal deformation, erosion and sedimentary processes on sedimentary basins
  • ATOM – a coupled atmospheric-ocean circulation code jointly developed by Prof. Roger Grundmann and EarthByte.

EarthByte’s expertise in tectonics, geodynamics and surface process modeling is enhanced by close collaborations with leading palaeoclimate modellers and geochemical oceanographers.  … Read more…

GPlates

raster_0029Ma

GPlates Raster 0029MaGPlates is desktop software for the interactive visualisation of plate tectonics.

The EarthByte Group leads the development of the open-source plate reconstruction software GPlates. GPlates enables the interactive manipulation of plate tectonic reconstructions and the visualisation of geodata through geological time, and it facilitates interoperability of plate tectonic data and models with geodynamic computing services for applied and fundamental research purposes.

The EarthByte Group is now exploring new directions of e-research by enabling GPlates technology in the Cloud, as part of our ongoing collaborative project researching Big Data Knowledge Discovery for Natural Sciences, … Read more…

The Basin GENESIS Hub

Basin GENESIS Hub logo

Basin GENESIS Hub logoThe ARC Research Hub for Basin Geodynamics and Evolution of Sedimentary Systems (Basin GENESIS Hub) is a showcase of connecting “Big Data” analysis and high-performance computing in an open innovation framework. The hub will fuse multidimensional data into 5D basin models (space and time, with uncertainty estimates) by coupling the evolution of mantle flow, crustal deformation, erosion and sedimentary processes using open-source modelling tools.

The project will develop quantitative, cutting edge data analysis techniques to underpin the testing of new concepts for understanding basin structures, and aid in driving sustainable use of basin resources. The development of new high-performance simulation and data mining tools, making use of new petascale computing capabilities, will connect big, multidimensional data sets to cutting edge machine learning and modelling algorithms to cross a wide spectrum of spatial and temporal scales. … Read more…

The Virtual Geological Observatory: a 4D view into the earth through deep-time data-mining (VIRGO)

Presentations Image

Project Summary
Australian Laureate Fellow Prof. Dietmar Müller and the EarthByte Group within the University of Sydney’s School of Geosciences are embarking on an ambitious new research program: building a Virtual Geological Observatory.

Fifty percent of Australia’s export income comes from the minerals and energy sector. Over three-quarters of these exports come from deposits discovered prior to 1980. … Read more…

Gondwanaland extension, breakup and continental margin evolution

Project Summary
Plate reconstruction models for the rifting and separation of Gondwanaland’s conjugate margins continue to be poorly constrained in detail. We propose to develop a new plate model for the entire Indian ocean by synthesizing old and new geological and geophysical data using our plate tectonic software system. We will test continental fit reconstruction hypotheses and alternative models for the early opening of the Indian Ocean by using a variety of reconstructed gridded and vector data sets.  … Read more…

Understanding the deep driving forces of Earth’s large-scale topography through time

Global paleogeography figureProject Summary
Continents and sedimentary basins through time record fundamental Earth system cycles, reflecting environmental change, migration of fauna and flora and shifting coastlines. It was originally thought that successive advances and retreats of shallow inland seas mainly reflect global sea level variations (eustasy). It is now well known in principle that large-scale surface morphology such as the high topography of the East African Rift, the low-lying Amazon River Basin and the southwest to northeast tilt of the Australian continent are strongly controlled by processes deep within the Earth, but progress has been slow in quantifying the magnitude and time-dependence of these relationships. … Read more…

Australian Paleo-stress map project

Fig12_0Ma-6Ma_asmUsing the engineering finite element modelling software package ABAQUS we have modelled the horizontal compressive stress of the Indo-Australian plate for time periods dating from the mid-Cretaceous. This work was carried out as part of the Tectonic Reactivation and Palaeo-Stress (TRAPS) Linkage project in collaboration with Shell, BHP Billiton,Woodside Petroleum and SANTOS in order to create a framework for predicting the tectonic reactivation of faults through time.
