Terrestrial fuel spills in Antarctica commonly occur on ice?free land around research stations as the result of human activities. Successful spill clean?ups require appropriate targets that confirm contaminated sites are no longer likely to pose environmental risk following remediation.
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.
A method for combining a proportional-hazards survival time model with a bioassay model where the log-hazard function is modelled as a linear function of log-concentration combined with a cubic smoothing spline function of time is described.
Chemical contamination resulting from human activities has been identified in … nearshore marine environments in the vicinity of Antarctic Research Stations. To better … manage and remediate contaminated sites, and to assess the risks of ongoing activities…
Developing water quality guidelines for Antarctic marine environments requires understanding sensitivity of biota to contaminant exposure. Toxicity tests with Antarctic … invertebrates have shown response times to metal exposure takes far longer than the durations of standard bioassay methods.
As zooplankton is an important food source for consumers, and a major source of recruits to the benthic community, impacts on sensitive zooplankton communities have the potential to significantly alter nearshore marine ecosystems in Antarctica.
Understanding the sensitivity of Antarctic organisms to metal exposure is essential … for developing Antarctic specific Environmental Guidelines to manage contamination risks. For … the first time…
As zooplankton is an important food source for consumers, and a major source of … recruits to the benthic community, impacts on sensitive zooplankton communities have the … potential to significantly alter nearshore marine ecosystems in Antarctica.
Zooplankton species are an important component of the Antarctic coastal ecosystem. The strongly seasonal sea ice cover and phytoplankton availability has driven a modification in the life cycles of many Antarctic zooplankton species. In general only one cycle is completed each year.
Catch per unit effort (CPUE) is often the only data available from historical fisheries for inferring distribution and abundance of exploited populations. CPUE underestimates variations in relative abundance when gross effort data are only measured in total operating days.
Evaluating the demographic trends of marine top predators is critical to understanding the processes involved in the ongoing rapid changes in Antarctic ecosystems. However, the remoteness and logistical complexity of operating in … Antarctica, especially during winter…
We describe a new breeding behaviour discovered in emperor penguins; utilizing satellite and aerial-survey observations four emperor penguin breeding colonies have been recorded as existing on ice-shelves. Emperors have previously been considered as a sea-ice obligate species…
Length frequency data (LFD) are an important input to integrated stock assessments, and statistical tests for variables that significantly influence the length distribution of fish can assist in the definition of effort strata, typically denoted as fisheries or sub-fisheries…
Prior to the satellite era, ice core records have been used as a proxy for past sea-ice extent in Antarctica. This information is important for investigating long-term trends in sea-ice coverage.
To better attribute the total ozone column (TOC) anomalies observed from the ozone … measurements in Ukraine, the climatologies of annual ozone cycle along the latitudinal … band 40–60° N with the 30° step in longitude have been analysed.
The continent of Antarctica has experienced some of the largest rates of both surface warming and cooling found anywhere on the planet. Unlike in the Arctic, where sea ice has been declining…
