Potential Adélie penguin breeding habitat (defined as ice-free land with area >4000 m2 and within 500 m of the ocean) in the Australian Antarctic Territory (AAT) was mapped using a GIS…
Tide gauges remain the fundamental instrument used to measure water level in the coastal environment. Issues … surrounding the calibration and vertical datum control of tide gauges are therefore fundamental in studies involving … the determination of absolute sea level and its variation over time.
Identification of DNA sequence diversity is a powerful means for assessing the … species present in environmental samples.
Seismic anisotropy is investigated across the previously unstudied region of central East Antarctica including new coastal locations and remote, temporary stations far inland.
Domain and purposive ontologies provide explicit and formal definitions of real-world concepts. They are indispensable components of any system whose objective is to support the exchange and semantic integration of data and information.
Law Dome, in coastal East Antarctica, is a relatively low-latitude site (6646S) with a strong maritime … climate, dominated by cyclonic precipitation which produces high snow accumulation rates and very … well-resolved ice core records.
The efficacy of a new mass-transfer method for … estimating milk intake was examined in Antarctic fur … seals (Arctocephalus gazella) at Iles Kerguelen. Our … method differed from previous mass-transfer approaches … in that we estimated milk-mass transfer as the maternal … mass lost (MML; kg)…
Extreme solar processes at the Sun on 2001April 15 accelerated protons to relativistic energies, resulting in a groundlevel … enhancement in cosmic rays observed at Earth. The GOES 10 spacecraft measured the proton flux directly…
Previous studies of impacted sites near Casey Station, Antarctica, have revealed elevated concentrations of metals and metalloids, particularly Cd, Cu, Fe, Pb, Sn and Zn in marine sediments. However…
A field trial for removal of dissolved metal contaminants in water from an abandoned waste disposal site, using ion-exchange … columns of an iminodiacetic acid chelating ion-exchange (IDA) resin, was conducted at Casey Station, Antarctica. An on-site … monitoring technique…
Salinity and lowtemperature effects on adsorption of contaminant metals from … water using an iminodiacetic acid (IDA) ion-exchange resin, were investigated under … dynamic flow conditions. The order of selectivity of the resin (20°C and 0% seawater) was: Cu2+Pb2+Cr3+ Ni2+Cd2+Zn2+ Low temperature…
Effects of salinity and low temperature on the removal of dissolved contaminant … metals from water by an iminodiacetic acid (IDA) ion-exchange resin, Amberlite … IRC748, were investigated under batch equilibrium conditions. As expected for ions … retained by chelation…
Sludge reduction and dewatering is an important aspect of water and waste water treatment. This is especially true in the case of … Australia’s Antarctic contaminated site remediation program…
An extensive Pb isotope ratio survey of ∼100 marine sediment samples from near Casey … Station, East Antarctica has been undertaken. Sediment surface grabs and cores were … collected over nine years between 1997–2006 and, following HF total digestion, were … analysed by magnetic sector ICP-MS.
A method is described for determining the relative extent of weathering in moderately biodegraded, hydrocarboncontaminated … soils from Antarctica. Plotting the pristane diastereomer ratio (PrDR) vs. pristane/phytane (Pr/Ph) allows … the relative extent of weathering…
1. Correlational studies of reproductive success are plagued by difficulty over the direction of … causation. For example, improved reproductive success with age can result from increased … experience or reproductive effort, or selection against low-quality phenotypes that survive poorly.
ABSTRACT: Collisions with vessels are a well-documented conservation problem for some populations of large whales (LW) in the Northern Hemisphere. Less attention has been given to incidents in the Southern Hemisphere or to small cetaceans … (SC) worldwide…
In September 2007, a multi-disciplinary sea-ice voyage, jointly organised by the Australian Government Antarctic Division and the Antarctic Climate and Ecosystems Cooperative Research Centre, sailed from Hobart. The focus of the Sea Ice Physics and Ecosystems Experiment (SIPEX)…
The operating principle of atmospheric Rayleigh LIDAR (light … detection and ranging) systems is that the range-corrected return backscatter … signal is directly related to atmospheric density.
Profiling the ground layer turbulence for daytime seeing applications using an array of photodiodes has been documented … in literature, in particular by Beckers who coined the term “SHABAR” for the instrument, short for Shadow Band … Ranger.
Abstract. We examined sexual dimorphism in 11 morphological characters of the Flesh-footed Shearwater (Puffinus … carneipes) and used these characters in a discriminant function analysis (DFA) to enable sexual classification in the field.
Australia’s Antarctic territory contains several hydrocarbon-contaminated sites of varying size and severity as a result of fifty years of human activities in the region. Contaminated site remediation in Antarctica is more challenging than in Australia.
Spatial Data Infrastructures (SDIs) have been developing in some countries for over 10 years but still suffer from … having a relatively small installed base. Most SDIs will soon converge around a service-oriented-architecture (SOA)…
