1.Ecosystem change is predicted to become more prevalent with climate change. Widespread dieback of cushion plants and bryophytes in alpine fellfield on Macquarie Island may represent such change. Loss of the keystone endemic cushion plant, Azorella macquariensis…
A method for combining a proportional-hazards survival time model with a bioassay model where the log-hazard function is modelled as a linear or smoothing spline function of log-concentration combined with a smoothing spline function of time is described.
Terrestrial fuel spills in Antarctica commonly occur on ice-free land around research stations as the result of human activities. Successful clean-up of spills not only requires appropriate remediation strategies and technologies that are effective in cold climates…
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.
Macquarie Island currently has no specific water quality guidelines to indicate a safe level of contamination on the island. This study investigated the toxic effects and accumulation of Cu and Zn in the subantarctic invertebrate, Exosphaeroma gigas. Further to this…
Current interpretation of histological alteration in fish as an indicator of contaminant impact is subjective. Generally severity of alteration is poorly described, and does not allow direct comparison between studies. A histological health index (HHI) modified from Bernet et al (1999)…
During the 2009/2010 summer field season a comprehensive environmental impact assessment (EIA) of the sewage discharge at Davis Station, East Antarctica was conducted. As part of this EIA, a preliminary histopathological survey of the gills and liver in the emerald rock cod (Trematomus bernacchii)…
