Six ice cores were collected during the 1997/1998 summer season along the 2000 m contour of Wilhelm II Land (ASAC 2085), followed by fifteen cores the following season from the 1800, 1500 and 1000 m contours in the same area (ASAC 1109)…
Over the past three years a successful collaboration between a university scientist, the AADC … and EPPS has occurred, where old field data from the 1980s has been resurrected using new … mapping technologies to produce a detailed vegetation map of Heard Island. In this paper…
Monitoring includes both targeted studies designed to verify the predicted effects of specific … activities and more exploratory studies designed to detect “unknown” or unpredicted impacts. In the marine environment monitoring typically begins with an empirical experiment or survey…
In the Antarctic summer of 2003/04 Australia began the remediation of an abandoned waste … disposal site at Casey Station, East Antarctica. Waste material and contaminated soil were … removed via excavation and returned to Australia for appropriate treatment and disposal.
Permeable reactive barriers are used to adsorb contaminants from soil water. Their fillings are granular … materials whose stability under freezing conditions has not been demonstrated. In this research, three granular materials(activated carbon…
As with human cytomegalovirus (HCMV) infection of humans, murine CMV (MCMV) infection is … widespread in its natural host, the house mouse Mus domesticus, and may consist of mixed … infection with different CMV isolates.
Once again Antarctica is under threat with the proposal by Senator Barnaby Joyce to have mining sanctioned by the Australian Government. Dr Tracey Rogers, presenter of the 2006 J D Stewart Address at the University of Sydney Faculty of Veterinary Science…
During every austral summer season, the Japanese Antarctic Research Expedition (JARE) has been conducting routine zooplankton observations with a NORPAC standard net since … 1972 (JARE 14). The NORPAC standard net method seems to be suitable for analyzing … macroscale distributions. However…
Antarctica remains one of the last bastions of exploratory limnology. Lakes in many regions … remain completely unknown, in part because of their often cryptic nature. Of particular interest … is whether the biological communities present in these isolated lakes consist of recent (postglacial)…
The invertebrate animals that inhabit ice-free areas of East Antarctica have been studied … since the earliest days of Antarctic science. However, even though biodiversity and … biogeography is reasonably well known for some regions (e.g. Southern Victoria Land)…
