This presentation introduces a recently awarded Australian Antarctic Science (AAS) project as part of the research theme 1 'Climate Processes and Change'. This project utilises the technique of Global Positioning System (GPS) Radio Occultation (RO)…
Environmental pollution resulting from fuel spills in Antarctic waters is increasingly likely with the rise in shipping associated with tourism and research activities, both of which require and transport large quantities of fuel.
Fuel spills in Antarctic waters are increasingly likely with the rise in shipping in the region related to tourism and research activities, both of which require and transport large quantities of fuel. While fuel dispersants are not currently used in the management of fuel spills in Antarctica…
Poa annua is the most widespread alien species in the sub-Antarctic, occurring on all major island groups and is invasive and spreading on the Antarctic Peninsula. P. annua colonises areas disturbed by human activity, seal wallows, penguin rookeries and glacial moraines.
Floral development of two alien species (Cerastium fontanum, Poa annua) were monitored through the summer of 2013/14 at three different altitudinal sites (coastal, hillside and plateau) on the North eastern end of sub-Antarctica Macquarie Island.
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.
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.
Stressors associated with climate change, and contaminants resulting from the activities of humans, are affecting organisms and ecosystems worldwide. Until recently, the impacts of these stressors on marine ecosystems have largely been examined in isolation.
Stressors associated with climate change, and contaminants resulting from the activities of humans, are affecting organisms and ecosystems worldwide. Until recently, the impacts of these stressors on marine ecosystems have largely been examined in isolation. However, with predicted climate change…
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.
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.
