Polar Mesospheric Clouds (PMCs) and Polar Mesospheric Summer Echoes (PMSE) were … simultaneously observed during the 2005-2006 austral summer above Davis, Antarctica … (latitude 68.6°S). This is the first time such observations have been obtained from the … southern hemisphere.

During early August 2005, the size of the Antarctic ozone hole, as measured by the area … enclosing the 220 Dobson Unit contour of the total ozone column, grew more rapidly than … previously observed for that time of year. Using global ozone and meteorological data…

A mechanism where reconnection between the Solar Interplanetary Magnetic Field and the … Geomagnetic field, deposits energy in the polar atmosphere was first observed in Antarctica. The propagation and attenuation of plasma waves occurs in the polar ionospheric waveguide … at 300km altitude…

Considerable debate is ongoing as to whether there is a temperature difference between the … northern and southern hemisphere polar mesopause regions of the atmosphere. In part this … debate has been fuelled by the reported lack of southern hemisphere Polar Mesosphere … Summer Echoes (PMSE)…

This talk will describe the cosmic ray physics behind different cosmic ray muon telescopes, such as Hobart Scintillator Telescope, Nagoya Scintillator Telescope, Matsumoto and Mawson … Proportional Counter,MuSTAnG and SanMartinho ScintillatorTelescopes.

Ground Level Enhancements (GLEs) arise when protons are accelerated to relativistic energies … at the sun, invariably associated with X-class flares, and the protons propagate to Earth and … produce statistically significant increase in ground based cosmic ray detectors.

A review of the present Australian activity in SpaceWeather research and forecasting is presented … together with a summary of the Australian SpaceWeather Plan to 2010 and beyond. Australian … researchers are in the process of developing a decadal plan for all solar-terrestrial research…

It is well known that Geomagnetic Storms change the geomagnetic field configuration, thus … changing the local geomagnetic cut-off. The effect of such changes on cosmic ray induced … charged particle fluxes at aircraft altitudes is investigated.

Thermal infrared images of the cloud-free surface of the Antarctic ice sheet exhibit subtle … stream-like features that can be traced over hundreds of kilometres. The stream features are … superimposed on other features in the temperature field related to the surface topography of … the ice sheet.

We present results of modelling iceberg tracks around East Antarctica, using the observed … long-term tracks of massive icebergs as reference data.

The collapse of the Larsen A and B and other ice shelves fringing the Antarctic Peninsula … coastline raises questions about the status of ice shelves in other parts of the continent. Are … the large ice shelves along the East Antarctic coast also in danger of permanent collapse…

The initial aim of the research, beginning in the 02/03 season, was to undertake some … regional mapping of the ice shelf, and to determine if marine ice could be differentiated from … meteoric ice employing the seismic technique. In 2002/2003…

An air-borne radio echo sounding survey was conducted over the Amery Ice Shelf, East … Antarctica, in December 2003. Nine transverse profiles were obtained approximately normal … to the flow direction, together with one longitudinal profile for a total length of flight lines of … about 1000 km.

Comparison of surface elevations measured by terrestrial survey in 1987 over the grounded … part of Totten Glacier with elevations measured by the Geophysical Laser Altimeter System … on NASA’s ICESat in 2003 shows that there has been substantial lowering of the surface of … around 10 m over 16…

Glaciological and over snow programs were the only possible avenues available for … determining dh/dt and mass balance in the 1960s. Law Dome in East Antarctica was … extensively traversed with several methodologies including gravity during the 1960s and into … the 1970s.

The phase lag between atmospheric composition (air bubbles) and temperature (water isotopes) can be quantified from ice cores provided that the age difference between entrapped air and the surrounding air can be correctly estimated. This difference depends on the lock-in depth (LID)…

Numerical simulations and laboratory experiments confirm my initial research hypothesis stating that dense water cascading down a submarine canyon induces localised upwelling of deeper water onto the shelf. This process, not described before…

Water mass volumes in the Southern Ocean are evaluated in a section between … Antarctica and Tasmania for the period 1991–1996. Antarctic Bottom Water … consisted of Weddell Sea Bottom Water and water formed along the Ade´ lie … Coast.
