Surface snow accumulation along the Chinese ITASE traverse line was measured using … bamboo stakes. Stakes along the initial (coastal) 300 km of the line were installed in 1997. The stake network was extended to 465 km in 1998, to 1100 km in 1999 and finally to 1228 … km (from the coast to Dome A)…
The internal structure of the Law Dome ice cap is being investigated by studying ice cores obtained from several sites along the summit - Cape Folger line. Profiles of measured physical properties for four of the ice cores from near the margin of the ice cap are presented.
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…
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…
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)…
The southern elephant seal (Mirounga leonina) population at Macquarie Island represents … about 10% of the world’s population. The number of adult females breeding at the island has … decreased substantially since the first whole island census was conducted in 1952.
This paper provides the first evidence to relate Leopard Seal numbers with sea-ice … concentrations in a region of the Eastern Antarctic pack ice and to propose a biological … mechanism (krill availability) to link the two. Leopard seals have been periodic, and sometimes numerous…
Studies of carbon flux and ecosystem processes require models of the population dynamics … of phytoplankton and other microbial organisms, but with over 500 protistan species known to … inhabit these waters, it is not feasible to model them individually. Instead…
Monitoring of zooplankton communities in the northern hemisphere has provided valuable … insights into plankton / climate interactions, and changes to plankton communities have been … shown to impact significantly on higher trophic levels.
Significant changes in zooplankton composition have occurred in various ocean systems in … recent years. These changes can be quite dramatic, occurring within one or two seasons, as … happened with the regime shift in the North Sea and North Atlantic in the late 1980s.
We determined the effects of UVR (280 – 400 nm) on Antarctic marine protists over the … summer of 2001/02 in incubation experiments with light exposures of PAR, PAR+UVAR and … PAR+UVAR+UVBR.
The international cooperation that makes Antarctica a continent for science has enabled … observations of the Antarctic middle atmosphere that are not possible anywhere else on … Earth. Atmospheric radars operated by Australia (Davis), Japan (Syowa), the UK and the … USA (Rothera)…
A survey of the size characteristics of the population of icebergs around the whole of the … Antarctic coastline was carried out using synthetic aperture radar images. A total of 36…
A field experiment investigating the effect of oil contamination on benthic microbial communities was conducted near Casey Station, East Antarctica.
Prior to environmental legislation in the 1980s, anthropogenic waste in Antarctica was often deposited into … landfill sites or into the sea. This resulted in metal contamination in terrestrial and near-shore marine … environments. In this study…
Snow accumulation rates at the summit of Law Dome are examined on three different … timescales. For the full record covering the last ~ 90,000 years accumulation rate is … determined as an output of the model used for ice core dating.
The dominant generator of the atmospheric electric circuit is meteorological activity in the … form of thunderstorms and electrified clouds, while the flow of the current within the circuit is … principally controlled by atmospheric ionisation by cosmic rays.
The atmospheric tides are a dominant and persistent feature of the mesosphere and lowerthermosphere … region of the atmosphere which spans from 80 to 120km above the Earth’s … surface. The tides…
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…
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.
