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.
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.
Within the Pycnogonida, genetic studies have … revealed that Colossendeis megalonyx Hoek (Challenger … Report, Zoology, 3(X), 1–167, 1881), consists of a complex of … several cryptic or overlooked species.
Stressors associated with global climate change and local human activities are affecting marine organisms worldwide. Stressors include changes in temperature, salinity and acidification, in addition to contaminants including metals and hydrocarbons.
Metals at contaminated sites in Antarctica rarely occur in isolation, but rather occur in complex mixtures with a number of contaminants. Despite this, the majority of previous ecotoxicological studies on Antarctic marine biota have investigated the toxicity of single metals only.
Sewage discharge into near-shore marine ecosystems is one of the most common forms of contamination that occurs in Antarctica today, and is likely to impact on the biota living in these habitats. In this study the morphological responses of four species of Abatus heart urchins (A. philippii, A.
Despite the widespread use and transport of fuels in Antarctica, there is very limited data available on the behaviour and weathering of these fuels in the Antarctic marine environment. The potential impacts of a fuel spill on marine biota are largely unknown.
