Mechanisms of proxy uptake in biominerals. This project plans to combine nano-analytical and aquaculture methods to develop new models that improve the reliability of paleoclimate reconstructions. The compositions of shells and skeletal materials of marine invertebrates are essential archives for quantifying temperatures and environmental conditions before modern climate records began.

This project plans to combine nano-analytical and aquaculture methods to develop new models that improve the reliability of paleoclimate reconstructions. The compositions of shells and skeletal materials of marine invertebrates are essential archives for quantifying temperatures and environmental conditions before modern climate records began. However, their reliability relies on understanding their formation. Emerging knowledge from material sciences indicates that these biocarbonates form via transient precursors rather than direct precipitation from seawater, profoundly affecting their interpretation. This project plans to transfer this new understanding to the earth sciences using nanoscale analytical methods including in vitro geochemical partitioning experiments. This would enable realistic models for geochemical proxy behaviour to be developed, significantly improving paleoclimate interpretations and assessments of ocean acidification effects on marine calcifiers.Read moreRead less
How the complexity of continental breakup controls ocean circulation. This project aims to address the evolution of oceanic seaways formed during separation of tectonic plates (such as Australia and Antarctica). The seaways that form are key components modulating the global ocean circulation system and are implicated in major glacial expansion events. This project aims to unravel their role relative to other drivers for example carbon dioxide (CO2). Unravelling the influence of seaway opening co ....How the complexity of continental breakup controls ocean circulation. This project aims to address the evolution of oceanic seaways formed during separation of tectonic plates (such as Australia and Antarctica). The seaways that form are key components modulating the global ocean circulation system and are implicated in major glacial expansion events. This project aims to unravel their role relative to other drivers for example carbon dioxide (CO2). Unravelling the influence of seaway opening compared with declining CO2 in the onset of Antarctic and Northern hemisphere glaciation will enable more accurate future climate simulations. The project will also give international exposure and training to the next generation of numerically adept geoscientists and oceanographers.Read moreRead less
The stratigraphic architecture of continental margins (MARGINS). The project seeks to increase our understanding of how continental margins develop. Emphasis is given to studying the controls exerted on sedimentation by sea-level change, climate cycling, ocean front location, current-deposition and tectonics, using the southwest Pacific (temperate eastern NZ) as the prime fieldwork area. Sediment being transported across continental margins passes through a number of energy fences (e.g. piedmont ....The stratigraphic architecture of continental margins (MARGINS). The project seeks to increase our understanding of how continental margins develop. Emphasis is given to studying the controls exerted on sedimentation by sea-level change, climate cycling, ocean front location, current-deposition and tectonics, using the southwest Pacific (temperate eastern NZ) as the prime fieldwork area. Sediment being transported across continental margins passes through a number of energy fences (e.g. piedmont, shoreline, wave-base, storm-zone, shelf-edge), which together modulate sediment transport and deposition. These fences differ in their relative positions, magnitudes and effects on different margins. The research will combine onland and offshore studies, builds on data collected during ODP Leg 181, and is integrated with the international MARGINS "source to sink" program.Read moreRead less

The integrity of 3D geological models heavily relies on robust and consistent data interpretation. This project proposes an innovative workflow for 3D modelling to minimise geological uncertainty. Advanced visualisation and intelligent decision support methods will be combined to assist geological interpretation. Feedback on interpretation will be provided based on data evidence and consistency with expert knowledge and previous interpretations. The process can be considered as a spelling and grammar checker for geological interpretation. The outcome of this study aims to achieve an improved workflow that reduces model uncertainty, resulting in a broad and significant impact on the management of Australian mineral, energy and water resources.Read moreRead less
