Aerosol observations above the Southern Ocean and Antarctic sea ice are scarce. Measurements of aerosols and atmospheric composition were made in East Antarctic pack ice on-board the Australian icebreaker Aurora Australis during the spring of 2012.
The parameterization of gravity waves in the NCAR Whole Atmosphere Community Climate Model (WACCM) includes orographic, convective, and frontal sources. Even with these, the model simulates temperatures in the Antarctic lower stratosphere during winter and spring that are much lower than observed.
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)…
We review the 2012 Antarctic ozone hole, making use of various meteorological … reanalyses, remotely sensed ozone measurements and ground-based measurements … of ultra-violet radiation. Based on analysis of 33 years of satellite records…
Protoxylem plays an important role in the hydraulic function of vascular systems of both herbaceous and woody plants, but relatively little is known about the processes underlying maintenance of protoxylem function in long-lived tissues. In the present study…
The gammarid Paramoera walkeri is one of the most abundant amphipods in near-shore Antarctic waters. There has been increasing interest in P. walkeri as a test species for ecotoxicology studies and bio-monitoring for contaminants in Antarctica…
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.
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)…
Two sets of historical 3-ensemble simulations have been obtained with versions 1.0 and 1.3 of the Australian Community Climate and Earth System Simulator (ACCESS) to examine the effects of ozone change since 1960.
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…
Poa annua L. is the most widespread weed in the sub-Antarctic, present on all major island groups and on the Antarctic Peninsula. Its ability to withstand heavy grazing has enabled it to spread significantly on islands with introduced herbivores.
