Gravity wave drag parameterization in climate models MURPHY, Dr Damian Australia (or home country), Davis

Gravity waves are atmospheric waves that play a critical role in defining the dynamical state of our atmosphere.

Experimental krill biology: Response of krill to environmental change KAWAGUCHI, Dr So Australia (or home country), Marine Science

The experimental krill research project is designed to focus on obtaining life history information of use in managing the krill fishery - the largest Antarctic fishery. In particular, the project will concentrate on studies into impacts of climate change on key aspects of krill biology and ecology.

Development of environmental risk assessment and remediation guidelines for Antarctic and subantarctic marine and terrestrial environments. KING, Dr Catherine (Cath) Casey, Macquarie Island, Australia (or home country)

The risk of contaminants to marine and terrestrial ecosystems in the Antarctic and subantarctic are poorly understood. This information is crucial for development of site specific environmental standards.

Remediation of petroleum contaminants in the Antarctic and subantarctic SPEDDING, Mr Timothy (Tim) Davis, Australia (or home country), Casey, Macquarie Island

Fuel contamination poses a major threat to Antarctic ecosystems as fuel is persistent & potentially toxic in the environment. Natural attenuation in Antarctica is slow with intervention required to minimise environmental damage.

A multi-instrument approach to derive East Antarctic sea-ice dynamics HEIL, Dr Petra Marine Science, Australia (or home country)

In-situ and remotely sensed observations of sea-ice drift from the East Antarctic [EA] together with auxiliary data will provide a baseline of sea-ice motion and deformation, including any high-frequency processes that may be resolved from the available time-series.

How do Antarctic space-weather disturbances propagate northward to influence ionospheric density and structure above Australia and the Southern Ocean? CONDE, Dr Mark Mawson, Davis

A long-standing problem is why the mid-latitude ionosphere (eg over Australia) is sometimes enhanced during space weather storms, and sometimes depleted.

Geoscience Australia geodetic and geophysical monitoring program BATHGATE, Mr Jonathan Australia (or home country), Casey, Davis, Macquarie Island, Mawson, Other Antarctic Location (Territory of Heard Island and McDonald Islands)

Geoscience Australia operates an integrated geophysical observing system in Australia, its neighbouring region and Antarctica. This program represents the Antarctic and sub-Antarctic components of this system. It consists of four key elements:

Signature biomarkers for contaminant exposure associated with sewage and refuse legacy waste disposal sites in Antarctic fish and bivalves MONDON, Dr Julie Davis, Casey, Australia (or home country)

Chemical contamination of marine sediment and waters adjacent to Antarctic Research Station refuse disposal and sewage outfalls represent significant ecological risk.

Monitoring Ecosystem Stability in Model Marine-Derived Antarctic Lake Systems CAVICCHIOLI, Prof. Ricardo (Rick) Davis

We will examine ecosystem-wide stability of microbial communities in several marine derived lakes in the Vestfold Hills. Our studies to date reveal that the communities are very delicate.

Conservation Decision-making in Antarctic Terrestrial Ecosystems: 1.Alien Species BERGSTROM, Dr Dana Australia (or home country), Macquarie Island

This collaborative postdoctoral research project between the AAD and University of Queensland aims to undertake innovative analyses in conservation and ecology, with a focus on alien species distributions and associated ecosystem restructuring in the Antarctic and sub-Antarctic.
