Background … Incomplete species inventories for Antarctica represent a key challenge for comprehensive ecological research and conservation in the region. Additionally, data required to understand population dynamics, rates of evolution, spatial ranges, functional traits…
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…
One of the serious threats to the Antarctic marine ecosystem is the release of large volumes of petroleum fuel. Numerous fuel spill incidents have occurred and risks of a major spill are increasing due to continued expansion of human activity in the Antarctic region.
Antarctica is often considered a pristine wilderness, however, as human occupation and activities in the region increase, it is becoming increasingly apparent that this is not the case.
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…
The basis of using isotopic measurements to study trophic structure lies in documenting a regular and consistent pattern of isotopic enrichment with increasing trophic level. Nitrogen isotope ratios (δ 15N) in consumers become enriched in 15N by 3-4 % relative to their food…
Species of the genus Pyramimonas (Prasinophyceae) are a common, widespread, but minor component of the Antarctic marine phytoplankton. They are … often associated with the seasonal sea-ice environment. Pyramimonas gelidicola … (McFadden, Moestrup & Wetherbee, 1982)…
The brightness of the night sky at an astronomical site is one of the principal factors that determine the quality … of available optical observing time. At any site the optical night sky is always brightened with airglow, zodiacal … light, integrated starlight…
The water quality of a marine embayment (Brown Bay) was monitored during the remediation of an abandoned waste disposal site at … Casey Station, East Antarctica, using a combination of biomonitoring and chemical methods. The Antarctic amphipod Paramoera walkeri…
Remediation of the Thala Valley waste disposal site near Casey Station, East Antarctica was conducted in the austral summer of … 2003/2004. Biomonitoring of the adjacent marine environment was undertaken using the gammaridean amphipod Paramoera walkeri … as a sentinel species [Stark, J.S.…
In the Antarctic summer of 2003/04 Australia began the remediation of an abandoned waste … disposal site at Casey Station, East Antarctica. Waste material and contaminated soil were … removed via excavation and returned to Australia for appropriate treatment and disposal.
The Antarctic continent covers an area of nearly 14 million square kilometres, representing one-sixteenth of the Earths land surface. Ninety-eight percent of this area is covered by ice. The remaining 2% comprises widely scattered patches of rock and mineral terrain surrounded by snowfields…
