Submarine springs in the Great Barrier Reef Lagoon: the geological origin, physical properties and ecological significance of Wonky Holes. This project investigates submarine groundwater discharge (SGD) to the Great Barrier Reef (GBR) lagoon. As groundwaters often contain high loads of nutrients and other pollutants, point source SGDs called Wonky Holes, reputedly common yet scientifically unexplored in the GBR or elsewhere, may represent a significant pathway for the land-sea flux of these mat ....Submarine springs in the Great Barrier Reef Lagoon: the geological origin, physical properties and ecological significance of Wonky Holes. This project investigates submarine groundwater discharge (SGD) to the Great Barrier Reef (GBR) lagoon. As groundwaters often contain high loads of nutrients and other pollutants, point source SGDs called Wonky Holes, reputedly common yet scientifically unexplored in the GBR or elsewhere, may represent a significant pathway for the land-sea flux of these materials. This project will define the incidence and origin of Wonky Holes and determine the magnitude and physical and chemical properties of their discharge. These studies will advance our understanding of land-sea interactions, assist management of the GBR and improve regional hydrogeological models.Read moreRead less
Acoustic observation of Antarctic ice rifting and calving events using remote hydroacoustic listening stations. The calving activity of the Antarctic ice shelves is one of the major indicators of global climate change. Global warming induced by an increase in atmospheric CO2 will affect the Antarctic Ice Sheet, primarily in form of disintegration of the Antarctic ice shelves surrounding the continent. The processes of calving on the ice shelves may lead to a substantial increase of sea level aro ....Acoustic observation of Antarctic ice rifting and calving events using remote hydroacoustic listening stations. The calving activity of the Antarctic ice shelves is one of the major indicators of global climate change. Global warming induced by an increase in atmospheric CO2 will affect the Antarctic Ice Sheet, primarily in form of disintegration of the Antarctic ice shelves surrounding the continent. The processes of calving on the ice shelves may lead to a substantial increase of sea level around the world, with devastating effects on the continental coasts and low-lying islands. The method of remote acoustic observations investigated in this project is a new approach to the problem of creating an efficient and cost effective system to monitor rifting and calving of the Antarctic ice shelves.

Targeting organically-complexed iron species in seawater using selective solid-phase adsorbent resins. Iron limits primary productivity in 40% of the oceans. Its accurate determination is thus critical to understanding the functioning of marine ecosystems and their role in moderating Earth's climate. Recent findings indicate that serious discrepancies exist in iron concentrations obtained using different analytical methods. These discrepancies are believed to be due to the lability of organic ....Targeting organically-complexed iron species in seawater using selective solid-phase adsorbent resins. Iron limits primary productivity in 40% of the oceans. Its accurate determination is thus critical to understanding the functioning of marine ecosystems and their role in moderating Earth's climate. Recent findings indicate that serious discrepancies exist in iron concentrations obtained using different analytical methods. These discrepancies are believed to be due to the lability of organic and colloidal iron species to extraction by adsorbent preconcentration resins. This project will design and synthesise a range of functionalised resins for the selective extraction of iron species from seawater, advancing our knowledge of its bioavailability and leading to the generation of class-specific analytical methodologies.Read moreRead less
Pulsed oscillating mass analyser. Mass spectrometers are ubiquitous components in chemical analysis, but are often large and expensive. We have developed a new method for mass analysis, which is smaller and cheaper than existing technology. However, the analyser needs further research to determine whether it has the performance specifications to match the other technologies. The objective of this research is to characterise, explore and extend the prototype and to develop the appropriate math ....Pulsed oscillating mass analyser.

Friction and deformation occur from the mutual motion and interaction of microscopic particles and surfaces. This research aims to develop new theories and measurement techniques for these non-equilibrium phenomena by combining mathematical analysis and numerical computations with dynamic force measurement, surface modification, and surface characterisation on nanometre and molecular length scales.

Australian advances in quantitative x-ray imaging are at the leading edge of international efforts to permit 3D characterisation of the structure of materials and dynamic studies of structural changes. They have proven to be sensitive to local arrangement of materials at the nanometre scale, and they are emerging as critical tools in the development of advanced materials, which is a national research priority. This facility will allow the non-destructive 3D imaging of nanostructured materials to be performed as continual experimental development - something that is very difficult to achieve at synchrotron sources where access can be sporadic. The newly developed techniques will be applied to critical problems in emerging nanotechnologies.Read moreRead less
