Two major astronomical experiments are underway at the US Amundsen-Scott South … Pole Station. The first is the South Pole Telescope, a 10m sub-millimetre telescope de- … signed to measure primary and secondary anisotropies in the CMBR…
The remediation of the Thala Valley landfill, Casey Station, East Antarctica, is part of efforts to … clean-up contaminated sites associated with the Australian Antarctic Program. These sites, ranging from abandoned rubbish dumps to fuel spills…
: Recent technological advances in the study and dating of both land and marine glacial geologic features combined with improvements in both glaciological and post-glacial isostatic rebound modelling have led to significant improvements in our knowledge and understanding of the Antarctic Ice Sheets…
We present measurements and analysis of the isotopic composition (ä15Nbulk, ä15Ná, ä15Nâ, and ä18O) of nitrous oxide in 50 samples of tropospheric air collected at Cape Grim, Tasmania between 1978 and 2005 and in 11 samples of firn air from Law Dome, Antarctica…
We discuss an upcoming international airborne survey targeting two of the East Antarctica Ice Sheet's (EAIS) enigmatic … subglacial basins. Using a multi-instrumented long range aircraft we will address key issues in the origin and fate of … Earth's largest ice sheet.
Terrain analysis of vegetation distribution and satellite image classification generally require training data from numerous field sites. On remote subantarctic islands, where access is difficult and the opportunities for aerial photography are limited by cost and weather conditions…
This study implemented and applied a binary ensemble classifier for … identification of grazed vegetation communities on Macquarie Island from very … high resolution Quickbird imagery. Rabbit grazing has severely affected … Macquarie’s unique sub-Antarctic vegetation communities.
Supervised dive classification is a commonly used technique for categorising time-depth profiles of diving … vertebrates. Such analyses permit the description and quantification of dive behaviour and foraging tactics, and highlight feeding locations. Ideally…
Changes in buoyancy during an animal’s time at sea are a powerful tool for inferring … spatial and temporal foraging success. Buoyancy can be difficult to measure, but in some species of … seal, drift components of dives can be used.
The use of sophisticated telemetry logging devices has revealed that short-finned pilot whales employ … energetic sprints to chase down their deep-dwelling prey. These sprints are costly in terms of energy, and therefore oxygen…
Understanding the cryptic lives of wide–ranging wild animals such as seals can be challenging, but with the … advent of miniaturised telemetry and data–logging devices this is now possible and relatively straightforward. However…
Recently, Vergani et al. (2008) examined the … climatic drivers of population dynamics … (weaning mass) and foraging performance … (diet variation) from southern elephant … seals, Mirounga leonina, in the Atlantic sector … of the Southern Ocean.
1. In terrestrially breeding phocid seals males are significantly larger than females with their large … size conferring advantage in male–male competition, and increasing their ability to fast during the … breeding season, prolonging tenure and hence mating opportunities. 2.
The Global Muon Detector Network (GMDN) was … completed by installing a multi-directional cosmic-ray muon … hodoscope in Kuwait University in March 2006. The GMDN is … currently consisting of four multi-directional muon detectors … located at Nagoya (Japan), Hobart (Australia), Sao Martinho …
PLATO (PLATeau Observatory) is the third-generation astronomical site-testing laboratory designed by the University … of New South Wales. This facility is operating autonomously to collect both scientific and site-testing data from … Dome A, the highest point on the Antarctic plateau…
Over a decade of site testing in Antarctica has shown that both South Pole and Dome C are exceptional sites for … astronomy, with certain atmospheric conditions superior to those at existing mid-latitude sites. However, the highest … point on the Antarctic plateau, Dome A…
Pre-HEAT is a 20 cm aperture submillimeter-wave telescope with a 660 GHz (450 micron) Schottky diode heterodyne … receiver and digital FFT spectrometer for the Plateau Observatory (PLATO) developed by the University of New South … Wales. In January 2008 it was deployed to Dome A…
