Assessment of the potential consequences of large-scale eradication of rice grass from the Tamar Estuary, Tasmania. Introduced Rice grass has trapped large volumes of intertidal sediment, yet reduced amenity values of the Tamar Estuary, transforming beaches into muddy rice grass meadows, threatening aquaculture industries, and silting up coastal developments. This project will investigate the consequences of rice grass eradication, by determination of sediment volume trapped, contaminants contai ....Assessment of the potential consequences of large-scale eradication of rice grass from the Tamar Estuary, Tasmania. Introduced Rice grass has trapped large volumes of intertidal sediment, yet reduced amenity values of the Tamar Estuary, transforming beaches into muddy rice grass meadows, threatening aquaculture industries, and silting up coastal developments. This project will investigate the consequences of rice grass eradication, by determination of sediment volume trapped, contaminants contained, and monitoring of processes active after removal. The outcomes of this research will enable informed decisions on management of the Tamar rice grass infestation, and provide an understanding the impacts of large scale eradication to management authorities of similar infestations in Victoria, New Zealand, Europe, China and the USA.Read moreRead less

Are coastal wetlands vulnerable to bushfires? The ‘Black Summer’ fires burned extensive areas of coastal wetland not typically associated with fire impact. These wetlands rely upon plant growth and sediment delivery to respond to sea-level rise, processes which may be impacted by fire. This project aims to quantify the distribution and severity of fire impact, and establish post-fire vegetation and surface elevation trajectories. By integrating fire ecology and wetland science approaches, this p ....Are coastal wetlands vulnerable to bushfires? The ‘Black Summer’ fires burned extensive areas of coastal wetland not typically associated with fire impact. These wetlands rely upon plant growth and sediment delivery to respond to sea-level rise, processes which may be impacted by fire. This project aims to quantify the distribution and severity of fire impact, and establish post-fire vegetation and surface elevation trajectories. By integrating fire ecology and wetland science approaches, this project will ascertain the resilience of coastal wetlands to the cumulative impacts of fire and sea-level rise. Expected outcomes of this project include new, spatially-explicit fire management tools which will aid the sustainable, long-term management of coastal wetlands in a changing climate.Read moreRead less
Remotely sensed forest water use in space and time. Remotely sensed forest water use in space and time. This project aims to develop and apply new methods to scale forest water use from plot to catchment-level, using relationships between plot-level annual evapotranspiration and biophysical and biochemical properties of stands detectable by unmanned aircraft systems and other remote sensing platforms. Australia's water security depends on understanding how changes in forests from disturbance and ....Remotely sensed forest water use in space and time. Remotely sensed forest water use in space and time. This project aims to develop and apply new methods to scale forest water use from plot to catchment-level, using relationships between plot-level annual evapotranspiration and biophysical and biochemical properties of stands detectable by unmanned aircraft systems and other remote sensing platforms. Australia's water security depends on understanding how changes in forests from disturbance and climate change influence catchment water yields. This project will estimate water yields over time and space in ungauged catchments with disturbed eucalypt forests. This research is expected to enable more effective risk mitigation and planning for augmentations; improved fire management strategies; and better water management of the Murray Darling Basin.Read moreRead less
Using past climate extremes to guide infrastructure planning for the future. This project aims to analyse a 2000-year palaeoclimate record of single event and complex climate extremes to provide a long-term context for observed changes in climate extremes over recent decades. This project expects to generate new knowledge about long-term variability in the frequency and magnitude of climate extremes that occur on seasonal - decades time-scales. It also expects to provide information about com ....Using past climate extremes to guide infrastructure planning for the future. This project aims to analyse a 2000-year palaeoclimate record of single event and complex climate extremes to provide a long-term context for observed changes in climate extremes over recent decades. This project expects to generate new knowledge about long-term variability in the frequency and magnitude of climate extremes that occur on seasonal - decades time-scales. It also expects to provide information about complex extremes that involve multiple types of impacts (e.g. drought followed by flood, simultaneous drought and fire). Expected benefits of the project include improved understanding of climate extremes and improved risk estimates for the impacts of climate extremes on Australian government and industry infrastructure.Read moreRead less
Physics-aware machine learning for data-driven fire risk prediction. The 2019/20 Australian fire season was unprecedented in its extent, impact, and the response of fire agencies. In this project, we aim to answer the question: was the scale of these fires driven by known drivers of fire (drought, weather, fuels and ignitions), or were fundamentally new undescribed processes and phenomena involved? We will accomplish this by developing an innovative, physics-aware machine learning model of fire ....Physics-aware machine learning for data-driven fire risk prediction. The 2019/20 Australian fire season was unprecedented in its extent, impact, and the response of fire agencies. In this project, we aim to answer the question: was the scale of these fires driven by known drivers of fire (drought, weather, fuels and ignitions), or were fundamentally new undescribed processes and phenomena involved? We will accomplish this by developing an innovative, physics-aware machine learning model of fire risk and spread, trained and validated on a two-decade satellite fire record. The predictive ability of the model will be tested on the 2019/20 fire season to determine if novel drivers of fire can be identified, and the model itself will be operationalised into a novel short-to-mid term fire risk prediction tool.

The drowned: cultural and political geographies. This project aims to reveal and critically analyse the geographies of drowning and the drowned. Drowning is the third most common cause of death worldwide, and a subject of universal interest that is relatively limited in specifically cultural and political geographical research, policy, and debate. The project will be significant by rectifying that gap and investigating shared concerns about drowning’s abiding, widespread, profound effects. The e ....The drowned: cultural and political geographies. This project aims to reveal and critically analyse the geographies of drowning and the drowned. Drowning is the third most common cause of death worldwide, and a subject of universal interest that is relatively limited in specifically cultural and political geographical research, policy, and debate. The project will be significant by rectifying that gap and investigating shared concerns about drowning’s abiding, widespread, profound effects. The expected outcomes will include public debate about drowning and its cultural and political reach and management generated from a book, articles, and blog. Benefits will include new fundamental knowledge and practical insights about how to rethink risks and disasters in rapidly changing environments.Read moreRead less
Effect of climate boundary changes on the Southern Westerly Winds. This project aims to produce high quality data on how the Southern Westerly Winds (SWW) respond to largescale changes in climate boundary conditions over multiple glacial-interglacial cycles. Because the SWW are key drivers of Southern Hemisphere climate, Southern Ocean circulation and global carbon dioxide concentrations, it is important to understand how they respond to changes in boundary conditions. Uncertainty about how they ....Effect of climate boundary changes on the Southern Westerly Winds. This project aims to produce high quality data on how the Southern Westerly Winds (SWW) respond to largescale changes in climate boundary conditions over multiple glacial-interglacial cycles. Because the SWW are key drivers of Southern Hemisphere climate, Southern Ocean circulation and global carbon dioxide concentrations, it is important to understand how they respond to changes in boundary conditions. Uncertainty about how they do so limits attempts at accurate predictive climate modelling. This project will test conceptual models of SWW dynamics and provide essential boundary conditions for predictive climate models. The project intends to simultaneously build and support a research capacity and global network, and advance Australia’s knowledge and contribution in the area of global climate dynamics.Read moreRead less
The puzzle of landfast sea ice: ‘Fast’ ice and near-term climate impacts. Sea ice which is held motionless against the Antarctic coastline (so-called landfast, or 'fast' ice) is hugely important for global climate and Southern Ocean ecosystems but its extent has recently plummeted.
