Measurement of the spatial distribution of temperature and velocity in lakes using Acoustic Tomography. This project will investigate the use of acoustic tomography in lakes to continuously measure the lake-wide distribution of temperature and velocity. The challenges with lake acoustic tomography are the accuracy required in the travel time measurements over shorter distances, acoustic losses due to reflections and ensuring enough rays travel through the thermocline, the region of greatest inte ....Measurement of the spatial distribution of temperature and velocity in lakes using Acoustic Tomography. This project will investigate the use of acoustic tomography in lakes to continuously measure the lake-wide distribution of temperature and velocity. The challenges with lake acoustic tomography are the accuracy required in the travel time measurements over shorter distances, acoustic losses due to reflections and ensuring enough rays travel through the thermocline, the region of greatest interest in lakes. A pilot experiment in a deep lake will investigate the quality of travel time measurements computed from rays travelling through the thermocline of a strongly stratified lake. This has wide applications for the water quality management of lakes and reservoirs.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.

Infrared sensors and systems are finding increasing use in Australia's core industries: particularly defence, mineral exploration, environmental monitoring, precision agriculture, homeland security, and medical diagnostics. Due to the reduced cooling requirements, the Infrared detector structures to be investigated in this project have the potential to deliver high performance infrared technology at a significantly lower cost and, hence, widening its applications. The new science proposed in this project, and new technological knowledge expected from its application, will allow Australian researchers to participate and significantly contribute to the international effort in this field and to exploit any developed intellectual property.

Many important semiconductor devices for communications, lasers, high speed electronics and optical sensing are based on materials grown by Molecular Beam Epitaxy (MBE). This research will provide the first measurements of the reactions taking place during MBE and thus enable accurate growth of the complex multi-layered material required for improved semiconductor devices. In particular, this project will make a major contribution to Australia's established capability to produce and develop state-of-the art infrared sensors as required for defence applications, remote sensing of minerals and pollutants, chemical analysis, and health diagnostics. PhD students will be trained in advanced semiconductor growth and optical sensing technologies.Read moreRead less

Recently, advances in femtosecond lasers enabled access to T-ray frequencies, producing an important new imaging modality for non-invasive sensing of materials and structures. Internationally, T-rays represent a rich new science leading to advanced forms of biophotonics, biomedical imaging and spectroscopy. Non-invasive T-ray diagnostics of nano- and bio-materials are being hotly pursued. The outcome will be a strategically important Australian T-ray facility that will provide immediate and transparent nationwide access. Historically, industry is transformed every time a new part of the electromagnetic spectrum becomes accessible - T-rays are the next frontier.Read moreRead less
