Robotic Science from the High Plateau BURTON, Prof. Michael Australia (or home country), Other

Australia's astronomers are exceptionally well placed to lead and to partner major international programs in Antarctic astronomy. These bring Australian industry increased access to cutting edge technology, and create business opportunities in the infrastructure and support of Antarctic research.

Vulnerability of Antarctic marine benthos to increased temperatures and ocean acidification associated with climate change BYRNE, Prof. Maria Davis

Ocean acidification and warming are global phenomena that will impact marine biota through the 21st century.

An assessment of variability in the influx of cosmic dust during the Holocene and the potential effect on iron concentrations in the Southern Ocean. CROPP, Dr Roger Macquarie Island, Australia (or home country)

This research will determine variability in the influx and mineralogy of cosmic dust to the Southern Ocean during the Holocene from peat bog cores. Cosmic dust contains significant quantities of soluble iron, a micronutrient required for photosynthesis.

Spatial analysis of changing terrestrial ecosystems in the Windmill Islands and the sub-Antarctic LUCIEER, Prof. Arko Macquarie Island, Clark Peninsula ASPA, NE Bailey Peninsula ASPA, Australia (or home country), Casey, Windmill Islands

High latitude terrestrial ecosystems are experiencing rapid change, which is most likely caused by climate change, human impacts, and invasive species. Up-to-date and accurate spatial data at a range of scales are of crucial importance for mapping changes in these fragile ecosystems.

Monitoring climate change induced desertification of Antarctica using stable isotopic signatures ROBINSON, Prof. Sharon Wilkes Land Coast, Australia (or home country), Casey, Clark Peninsula ASPA, Davis, NE Bailey Peninsula ASPA, Vestfold Hills

We will use mosses to investigate the changing climate in Antarctica and the implications this has for terrestrial biodiversity.

Proteorhodopsins in Southern Ocean Bacteria BOWMAN, Dr John Mawson, Australia (or home country), Davis, Vestfold Hills

Bacteria in marine environments have been found to be able to partially support growth by using light to generate energy in a non-photosynthetic process. This is possible due to a special protein called proteorhodopsin.

Mass balance of the Totten basin in East Antarctica: Estimation and calibration from ground, air and space-based observations (TOT-Cal) WATSON, Dr Christopher Casey

Regions of Antarctica are undergoing significant change in response to the Earth's changing climate.

Southern Ocean nutrients and their links to climate change: insights from the metal and silicon isotope signature of diatoms ELLWOOD, Prof. Michael Australia (or home country)

Microscopic plankton (e.g. diatoms) form the base of the marine food-chain and account for ~40% of global primary production, and hence moderating our climate through the ocean's ability to drawdown CO2.

THE POLAR FÖHN OF THE McMURDO DRY VALLEYS: AN AGENT OF ENVIRONMENTAL CHANGE AND LANDSCAPE EVOLUTION MCGOWAN, A/Prof. Hamish Australia (or home country), Other

The McMurdo Dry Valleys represent the largest snow and ice free region on Antarctica. This unique landscape is believed to have remained essentially unchanged for > 13 million years and is the closest Earth analogue to conditions on Mars.

Quantifying the effects of long term environmental change on World Heritage Macquarie Island. SAUNDERS, Dr Krystyna Macquarie Island, Australia (or home country)

Climate change and feral animals are having profound effects on Macquarie Island, threatening its World Heritage values.
