Variability of the coastal Antarctic climate derived from fast-ice observations. [Observational] HEIL, Dr Petra Casey, Davis, Mawson

Weekly fast-ice and snow thicknesses from an ongoing long-term time-series together with meteorological data will be used to analyse ice-atmosphere interactions. Interannual changes will be studied for climate effects.

Monitoring for human impacts and introduced species in marine communities at Australia's subantarctic islands SMITH, Dr Stephen (Steve) HIMI, Macquarie Island, Marine Science, Australia (or home country)

To effectively monitor human imapcts on subantarctic ecosystems, in particular the introduction of new ‘pest’ species, long-term monitoring programs must be set in place.

Southern extension of the Trans Antarctic deformation project [observational] JOHNSTON, Mr Gary Transantarctic Mountains, Other

This is a cooperative project with the Ohio State University (OSU) and the United States Geological Survey (USGS).The project will establish a GPS deformation network along the Transantarctic Mountains in the eastern sector of the AAT.

Study of the biodiversity of the nitrogen fixing microbes of Antarctic origin and their physiology, evolution and enzyme structures NAJIMUDIN, Dr Nazalan (Naz) Davis, Mawson, Australia (or home country), Casey

The aim of this project is to determine the biodiversity of Antarctica microorganisms. Environmental samples will be used to grow microbes which will then be tested for their nitrogen fixation capability and other growth characteristics involved in adaptation.

Geophysical imaging, structural analysis, and alteration geochemistry of the Macquarie Island crust, to constrain the tectonic, and hydrothermal history of the ocean floor. DAVIDSON, Dr Garry Australia (or home country), Macquarie Island

Although oceanic crust covers about 60% of the Earth, relatively little is known of its geology and the processes that have created it. Macquarie Island represents a unique subaerial exposure of the seafloor, and an exceptional environment for active study and research into the ocean crust.

Subsurface investigations of Marine Plain GORE, Prof. Damian Vestfold Hills, Davis, Marine Plain Mule Peninsula ASPA, Australia (or home country)

Marine Plain at Vestfold Hills, contains a unique record of sea level, climate and glacial history within its sediments and microfossils. Coring of the deeper sediments will reveal how this part of coastal east Antarctica changed during the Neogene (26 million years-the present).

Identifying global change: stable isotope composition and cuticle characteristics of antarctic plants SCHMIDT, Dr Susanne Australia (or home country)

Plants from herbarium collections dating back to the 19th century will be compared with recent collections to gain an understanding of ecosystems responses to global change.

Introduced invasive terrestrial invertebrates on Macquarie Island: studies on ecology, origins and control STEVENS, Dr Mark New Zealand, Australia (or home country), Macquarie Island

Three soil animals, a land shrimp, a slater and a flat worm, were all introduced to Macquarie Island early last century. The three species were probably imported accidentally with sealers and their supplies from New Zealand.

Limnological and nearshore diatom communities of Heard Island: proxies of subantarctic climate change? MCMINN, Prof. Andrew HIMI

Heard Island offers scientists a unique subantarctic laboratory for investigating climate change.

Oceanographic and climatic evolution of Kerguelen Plateau region: Collaborative research aboard the Japanese research vessel Mirai HOWARD, Dr William (Will) Kerguelen Plateau, Marine Science, Australia (or home country)

This project seeks to monitor Holocene-Quaternary variability of Antarctic bottom water outflow at a known deep pathway (east flank of Kerguelen Plateau) into a major ocean basin.
