Looking back to see the future: Change in the Lambert Glacier and the East Antarctic Ice Sheet. To develop a comprehensive understanding of the Lambert Glacier of East Antarctica, from the time of the last maximum glaciation to the present, through an integrated and interdisciplinary study combining new field evidence - ice retreat history, geodetic measurements of crustal rebound, satellite measurements of present ice heights and changes therein - with other geological and glaciological data an ....Looking back to see the future: Change in the Lambert Glacier and the East Antarctic Ice Sheet. To develop a comprehensive understanding of the Lambert Glacier of East Antarctica, from the time of the last maximum glaciation to the present, through an integrated and interdisciplinary study combining new field evidence - ice retreat history, geodetic measurements of crustal rebound, satellite measurements of present ice heights and changes therein - with other geological and glaciological data and numerical geophysical modelling advances. The project contributes to the quantitative characterisation of the complex interactions between ice-sheets, oceans and solid earth within the climate system. Outcomes have implications for geophysics, glaciology, geomorphology, climate, and past and future sea-level change.Read moreRead less
Towards an Active and Passive L- and P-band soil moisture satellite mission. This project tests alternate configurations for remote sensing of soil moisture using a new state-of-the-art Active/Passive (ie radar/radiometer) P-/L-band (ie microwave) satellite concept through a series of airborne field experiments. Timely soil moisture information is critical to improved water management for food production in the face of climate variability. The challenge is to do this accurately over large areas ....Towards an Active and Passive L- and P-band soil moisture satellite mission. This project tests alternate configurations for remote sensing of soil moisture using a new state-of-the-art Active/Passive (ie radar/radiometer) P-/L-band (ie microwave) satellite concept through a series of airborne field experiments. Timely soil moisture information is critical to improved water management for food production in the face of climate variability. The challenge is to do this accurately over large areas with an appropriate spatio-temporal detail, and for a soil depth that closely approximates the layer which impacts crop/pasture growth and influences management decisions. The longer P-band allows deeper penetration into the soil while the active/passive combination uses the respective resolution and accuracy characteristics.Read moreRead less
Improving models of West Antarctic glacial isostatic adjustment through a new surface velocity field. This project seeks to "fix the scales" being used to weigh changes in the Antarctic ice sheet. Present measurements are biased by a failure to accurately account for mass changes beneath the ice and within the Earth itself. This project seeks to use new measurements of the changes in the shape of the Earth to calibrate out that bias.
Quantifying sea-level trends and extremes along Australia's coastal margin. Multi-decadal changes in sea-level, and sea-level extremes, cannot be well quantified along most global coastlines, including Australia's, because the high spatial variability of sea-level is under-sampled by the sparse set of long, high quality tide gauge records. Satellite altimetry provides an alternative data source with greater spatial sampling, yet experiences contamination from land within tens of kilometres from ....Quantifying sea-level trends and extremes along Australia's coastal margin. Multi-decadal changes in sea-level, and sea-level extremes, cannot be well quantified along most global coastlines, including Australia's, because the high spatial variability of sea-level is under-sampled by the sparse set of long, high quality tide gauge records. Satellite altimetry provides an alternative data source with greater spatial sampling, yet experiences contamination from land within tens of kilometres from the coast and also suffers from regionally correlated biases. This project proposes to address these problems through re-tracking radar altimetry waveforms to derive new data in the coastal margin, enabling the production of new inferences on sea-level change and extremes at dramatically improved spatial resolution around Australia.Read moreRead less

Improved Geodetic Modelling through Very Long Baseline Interferometry. We plan to develop a geodetic VLBI capability to provide independent confirmation of results from alternative techniques such as GPS and SLR and allow us to characterise and remove the systematic errors inherent in these systems, to produce an optimum, unified terrestrial reference system based on VLBI measurements, together with GPS/SLR data, especially for the Antarctic region.

We plan to develop a geodetic VLBI capability to provide independent confirmation of results from alternative techniques such as GPS and SLR and allow us to characterise and remove the systematic errors inherent in these systems, to produce an optimum, unified terrestrial reference system based on VLBI measurements, together with GPS/SLR data, especially for the Antarctic region. The ITRF is based on the VLBI ICRF linking our astrometric and geodynamic research programs.
We will estimate motion at sites from the combination of VLBI, GPS, gravity and tide gauge data for geodynamic effects, such as post-glacial rebound and tectonic motion, global mean sea level change and determine length-of-day (LOD) variations, focused primarily on understanding the contribution from the Southern Oceans.

Specifically, a novel UAV soil moisture mapping system based on passive microwave satellite remote sensing technology at L-band will be developed for near-surface soil moisture mapping at accuracies and spatial scales currently not attainable. These soil moisture maps will then be merged with irrigation water delivery models to calibrate for spatial variation in soil properties and/or correct errors in spatial variation of rainfall and evapotranspiration inputs. Ultimately the water balance predictions will be used for implementation of variable rate irrigation control at scales hitherto unattainable.Read moreRead less

Assessment of plant health and productivity is vital to ensure future food security of the global population under a changing climate. Chlorophyll fluorescence (CF), a signal emitted by green plants, can reveal this information.

Assessment of plant health and productivity is vital to ensure future food security of the global population under a changing climate. Chlorophyll fluorescence (CF), a signal emitted by green plants, can reveal this information. Although CF has revolutionised photosynthetic research, current measurements are limited to individual plants. Remote sensing of canopy CF is required for efficient management of agricultural crops, forests, and natural ecosystems and is crucial for accurate estimation of plant carbon assimilation and production. This project will deliver remote sensing technology to bridge the gap between leaf and canopy productivity and pave the way for understanding both artificial and solar induced canopy CF measured from space.Read moreRead less
