Predicting environmental extremes in a period of climate change. This project has the potential to reduce the uncertainty in the predictions of extreme winds and waves used to design and operate coastal and offshore facilities. Predictions are typically achieved by extrapolating recorded data to predict probable extremes. The uncertainties associated with this approach are very large.

This project has the potential to reduce the uncertainty in the predictions of extreme winds and waves used to design and operate coastal and offshore facilities. Predictions are typically achieved by extrapolating recorded data to predict probable extremes. The uncertainties associated with this approach are very large. This project aims to develop a new approach called ‘large ensemble aggregate’ analysis, which brings together data from alternative model predictions or alternative measurement locations to expand the effective data and avoid the necessity for statistical extrapolation. This approach may significantly reduce the uncertainty in estimating extreme values. This would reduce the cost of constructing coastal and offshore facilities and decrease the risk of catastrophic failure.Read moreRead less

This project will examine the mechanisms underpinning the high productivity in Antarctic coastal polynyas, which are ice-free oases within the sea ice supporting abundant marine life. The study expects to generate essential new biochemical and biological observations using autonomous platforms to understand phytoplankton dynamics in these inaccessible habitats along Australia’s Antarctic Territory. Expected outcomes include novel insight into the role of iron supply from melting glaciers in supporting marine production. This should reduce the high uncertainty in prognoses for polynya activity under anthropogenic climate change, and support Australia’s international leadership in conservation and management of important Antarctic ecosystems.Read moreRead less

This project aims to advance research on the internal structure and temporal change in the Antarctic ice sheet by analysing seismic ground motion records of natural sources, including ambient noise. This approach expects to complement existing satellite and airborne methods to resolve glacial structures over large areas and detect changes hidden under snow cover. The intended outcome is new knowledge of the ice sheet’s stratification, its long-term variation due to climate change, and its rapid response to local weather events. The benefits include improving the reliability of ice sheet evolution modelling and sea-level rise prediction, unlocking a polar gateway to study Earth deep interior, and preparing for space missions to icy worlds.

This proposal seeks support for a shared High Resolution Inductively Coupled Plasma Mass Spectrometry facility for Tasmanian researchers. The existing UTAS instrument is approaching end-of-life and is becoming increasingly unreliable. Access to enhanced capabilities embodied in a rejuvenated facility, along with a renewed lifespan, is essential for continued analysis of ultra-trace elements and isotopes in challenging samples from southern environments. The new instrument will allow TAS researchers and their (inter)national collaborators to undertake world-leading research, enhancing competitive profiles in a diverse range of research areas (oceanography, analytical chemistry, Antarctic studies, environmental assessment, geochemistry).

The expected outcomes include ocean model configurations that will improve estimates of key processes affected by tides, such as Antarctic ice shelf melt rates, ocean warming and the ocean's overturning circulation. The project is thus anticipated to provide significant benefits in predicting future climate change, sea level rise, coastal erosion and marine heatwaves. Furthermore, it will enable the Australian and global communities to better target conservation and mitigation efforts, and thus reduce the environmental, social and economic impact of climate change.Read moreRead less
An ensemble approach to studying the ocean's role in climate change. Using a newly-developed ocean model that harnesses the power of graphical processing units (GPUs) instead of the common central processing units (CPUs) we can run global ocean simulations at 1/50th the cost. Utilising this speed up, we aim to pioneer a modelling framework to perform ensembles of eddy-resolving global ocean simulations under various climate-change scenarios. This ensemble approach will enable us to separate the ....An ensemble approach to studying the ocean's role in climate change.

Utilising this speed up, we aim to pioneer a modelling framework to perform ensembles of eddy-resolving global ocean simulations under various climate-change scenarios. This ensemble approach will enable us to separate the changes we see in future projections that are due to climate change from the changes that occur in the due to the natural variations of the climate system. The project's outcomes will increase our confidence in future climate change projections, including ocean heat uptake, and sea level rise.Read moreRead less

They are buried pipes and are often old and deteriorating. Cost-effective methods to assess their physical condition are urgently needed. This research will develop a novel and advanced approach to determine the interior condition of pipes quickly and effectively using small water hammer pulses or waves. Paired pressure sensor arrays will be used to measure reflections of the waves in pipes and these methods will enable finer resolution and identification of pipeline faults, such as wall thickness loss and leakage while at the same time allowing operational continuity. The outcome will be powerful tools to more cost effectively manage these crucial assets.Read moreRead less
