High-latitude gravity wave processes and their 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.

Age and origin of the magmatism along the transpressional Australian-Pacific plate boundary JOURDAN, A/Prof. Fred Macquarie Island, Australia (or home country)

Located ~1500 km southeast of Tasmania, Macquarie Island is the only place on Earth where oceanic crust and mantle are preserved and undeformed above sea level.

Totten Ice Dynamics and Evolution KING, Prof. Matthew Other Antarctic Location (Territory of Heard Island and McDonald Islands), Australia (or home country)

Global sea level fluctuations are driven by changes in the mass balance of the world's ice sheets and mountain glaciers. These fluctuations arise from either the increased discharge of ice into the oceans or through increases in snowfall over these ice masses.

Drift of the Antarctic ice edge BENNETTS, Dr Luke Australia (or home country)

The project has the potential to transform understanding of the physical processes governing drift of the Antarctic ice edge.

CAMMPCAN – Chemical and Mesoscale Mechanisms of Polar Cell Aerosol Nucleation SCHOFIELD, Dr Robyn Marine Science, Australia (or home country)

Concentrations of aerosols in the polar front atmosphere above the Antarctic sea-ice differ significantly from those in the adjacent regions of the Antarctic continent and the Southern Ocean.

Reconstructing Carbon-14 of Carbon Monoxide to Constrain Long-Term Atmospheric Hydroxyl Variability ETHERIDGE, Dr David Casey, Australia (or home country)

We propose to investigate changes in Southern Hemisphere (SH) hydroxyl radical concentration ([OH]) over the industrial period.

A new approach to ice melting rates: Direct numerical simulation HOGG, A/Prof. Andrew (Andy) Australia (or home country)

Melting of grounded ice mass in the Arctic and Antarctic may play a key role in future global sea level rise and Earth's climate system. The Antarctic Ice Sheet is losing ice at an increasing rate, primarily due to ocean-driven melting beneath ice shelves.

Response of the Totten Glacier to past climate warming NOBLE, Dr Taryn Australia (or home country)

Understanding how, where and why ice sheets lose mass is an international scientific priority to meet the challenges of global change. The Totten Glacier is a major outlet glacier draining a large area of East Antarctica.

Physical drivers of ice-algal biomass and characterisation of under-ice habitats in the Antarctic pack-ice zone MEINERS, Dr Klaus Marine Science, Australia (or home country)

Sea ice plays a key role in Southern Ocean physics and biogeochemical cycles, and is a major driver of Antarctic marine ecosystem processes. In terms of supporting marine food webs, sea ice provides a substrate for ice algae which serve as food source for pelagic herbivores.

Atmospheric carbon fixation: a novel strategy driving niche development and climate adaptation in polar desert soils FERRARI, A/Prof. Belinda Casey, Australia (or home country)

The aim of this project is to challenge our global understanding of carbon fixation. In most ecosystems, phototrophic carbon fixation by plants, algae and cyanobacteria is the primary production strategy supporting higher trophic life.
