Australia-China Ozone Research Nexus (ACORN) KLEKOCIUK, Dr Andrew Australia (or home country), Davis

We will extend the detailed measurement record of atmospheric ozone in the vicinity of Davis station in East Antarctica using routinely launched balloon-borne ozone sensors.

The Antarctic Clouds and Radiation Experiment (ACRE) ALEXANDER, Dr Simon Macquarie Island, Marine Science, Australia (or home country), Davis

Clouds and their radiative effects have very large uncertainties in present climate models and their quantification continues to be a challenge. The inadequate representation of clouds and moist convection in climate models is the main limitation in current representations of the climate system.

Impact of changes in sea ice extent on primary productivity in the Southern Ocean: links between the iron and carbon cycles in fast ice and the marginal ice zone LANNUZEL, Prof. Delphine Davis, Casey, Marine Science, Australia (or home country)

Despite its potential to naturally fertilize the Southern Ocean with iron and to stimulate the biological carbon pump, the marginal ice zone has been understudied compared to other naturally fertilized areas.

Ice rheology for ice sheet modelling TREVERROW, Dr Adam Australia (or home country)

Presently the greatest source of uncertainty in forecasts of global sea level is the rate at which ice grounded on the Antarctic continent is discharged into the ocean. This uncertainty has driven significant recent developments in ice sheet modelling capability.

Ocean forced evolution of the Antarctic Ice Sheet GALTON-FENZI, Dr Benjamin (Ben) Other Antarctic Location (Territory of Heard Island and McDonald Islands), Australia (or home country)

Preparing for the impacts of sea-level rise needs an improved understand of the response of the Antarctic Ice Sheet to changing ocean conditions.

Detecting potential fishery related and climate change impacts through the CCAMLR Ecosystem Monitoring Program (CEMP) SOUTHWELL, Dr Colin Australia (or home country), Mawson

CCAMLR manages the harvest of Antarctic marine living resources so it is sustainable to both harvested and dependent species. The CCAMLR Ecosystem Monitoring Program is one means of achieving this objective.

The Role of Magnetospheric Plasma Waves in Driving Space Weather WATERS, Prof. Colin Other Antarctic Location (Territory of Heard Island and McDonald Islands), Casey, Australia (or home country), Davis, Macquarie Island, Mawson

Space weather is a significant hazard to modern technology. It results from energization of the Earth’s radiation belts and subsequent transport of relativistic particles to low altitudes.

Monitoring the status and trends of Antarctic seabirds to improve fisheries management and detect climate change impacts in east Antarctica SOUTHWELL, Dr Colin Australia (or home country), Casey, Davis, Mawson

Seabirds are useful indicators of fisheries and climate change impacts in the Southern Ocean. This project aims to develop and apply cost-effective monitoring approaches to determine population status and trends of a suite of seabirds across the AAT.

Long-term measurements of atmospheric nitrogen dioxide at Macquarie Island QUEREL, Dr Richard Macquarie Island

Measurements of nitrogen dioxide (NO2), one of the key trace gases in the atmosphere, improve our understanding of the changes in atmospheric chemistry which are caused by emissions of man-made gases (such as N2O, CFCs or GHGs) and natural events (such as volcanic eruptions).

Grass of the Oceans: quantifying biodiversity, environmental and climatic connectivity from a decade-long capture of Southern Ocean diatoms. ARMAND, A/Prof. Leanne Australia (or home country)

An Australian sediment trap program was launched between the Roaring 40’s and Furious 50’s in 1997. The three aligned sites were defined by varying nutrient, physical and carbon export properties.
