Fuel spills are a major source of contamination in terrestrial environments in Antarctica. Little is known of the effects of hydrocarbon contaminants in fuels on Antarctic terrestrial biota, and how these change as fuel ages within soil.
During the last deglaciation (21,000 to 7,000 years ago) global sea level rise was punctuated by several abruptmeltwater spikes triggered by the retreat of ice sheets and glaciers world-wide. However, questions regarding therelative timing…
Several fuel spills have occurred near Australia’s Antarctic stations, associated with the use of SAB diesel for power generation. This has resulted in significant petroleum hydrocarbon contamination in soils.
The Australian Antarctic Division is currently remediating fuel spills on Macquarie Island. To contribute to the development of appropriate remediation targets, the present study examines the response of springtail assemblages to Special Antarctic Blend (SAB) diesel.
There have been a number of fuel spills (diesels and lubricating oils) on sub-Antarctic Macquarie Island associated with fuel storage and power generation for the island’s research station. The Australian Antarctic Division is currently working to remediate these sites over the next 5-10 years.
A series of fuel spills (diesels and lubricating oils) have occurred on Macquarie Island associated with fuel storage and power generation for the Island’s research station. The Australian Antarctic Division is currently remediating these sites.
Fuel spills have occurred in Antarctic and sub-Antarctic regions, and comprehensive remediation strategies have recently been established to clean-up fuel spills at Australia’s Casey Station and Macquarie Island. However…
Numerous fuel spills associated with human activities in Antarctica have occurred and significant levels of petroleum hydrocarbon contamination have been reported near Antarctic stations.
Special Antarctic Blend (SAB) is a light end diesel fuel, comprised mainly of petroleum hydrocarbons (alkanes nC9-C14, trace levels of nC15-23). It is used as the main source for power generation at Australia’s Research Stations in Antarctica and the subantarctic, including Macquarie Island.
Manipulative field studies are useful for investigating cause–effect relationships between contamination and benthic community health. However…
Several fuel spills have occurred on subantarctic Macquarie Island (548300 S 1588570 E) associated with storing fuel and … generating power for the island’s research station. The Australian Antarctic Division began full-scale, on-site remediation of these sites … in 2009.
In response to several fuel spills on sub-Antarctic Macquarie Island associated with research station operations, the Australian Antarctic Division has initiated a 5-10 year plan to remediate the island’s contaminated sites using low cost in-situ techniques.
The Antarctic has experienced major changes in temperature, wind speed and stratospheric ozone levels during the last 50 years. However until recently continental Antarctica appeared to be little impacted by climate warming, thus biological changes were predicted to be relatively slow.
A baseline for persistent organohalogen compound (POC) accumulation in the Antarctic … keystone species, Antarctic krill (Euphausia superba) has been established for a 50¡ã longitudinal … range of the eastern Antarctic sector. Samples of adult krill…
In this talk we describe the intra- and inter-annual variability in the timing of breeding phenology over a 16 year period for the Adélie penguin (Pygoscelis adeliae) colony at Béchervaise Island, East Antarctica.
A 5 yr field experiment was carried out comparing the effects of Special Antarctic Blend (SAB) diesel, synthetic lubricant (Mobil 0W40), used synthetic lubricant (used Mobil 0W40) and a biodegradable lubricant (Titan GT1) on Antarctic benthic microbial communities.
In 2001 a unique field experiment was established to compare the longevity and effects of four different oils on the Antarctic benthic ecosystem. Clean sediment was collected, spiked with one of the oils: Special Antarctic Blend (SAB) diesel, synthetic lubricant (Mobil 0W-40)…
Sub-Antarctic islands have been subjected to petroleum hydrocarbon spills, yet no information is available regarding … the toxicity of petroleum hydrocarbons to these subpolar soils.
Detection of long-term climate change requires knowledge of natural variability in the oceanatmosphere … system. In the Southern Hemisphere, climate variability is evident on time-scales … of days to centuries, yet we know relatively little about how this forces interior ocean … fluctuations…
Current research utilises the recently installed Southern Hemisphere Imaging Riometer (SHIRE) located at Australia’s Davis Antarctic station to study riometer signatures associated with cusp-latitude magnetic impulse events (MIE’s) detected in co-located fluxgate magnetometer data.
