Metals are important nutrients to marine life but may cause toxicity at elevated concentrations. There is uncertainty about how sediment metal concentrations influence benthic biodiversity, in part because metal bioavailability depends on sediment properties.
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.
