Although satellite passive-microwave remote sensing is the main source of global sea-ice … information, the data products have never been adequately validated for East Antarctic … conditions.
Abstract The diet of pinnipeds is most commonly … inferred from morphologically diagnostic remains of prey … in their scats. Although this method can generate quantitative … estimates of diet simply, important prey types may not … always be detected.
Abstract. A pilot study assessment of the potential exposure to solar ultraviolet radiation (UVR) of expeditioners on the Australian Antarctic resupply voyages was carried out over the summer of 2004/05 using UVR sensitive polysulphone (PS) badges.
Using steel pins inserted into growing moss … colonies near Casey Station, Wilkes Land, continental … Antarctica, we have measured the growth rate of three … moss species: Bryum pseudotriquetrum and Schistidium … antarctici over 20 years and Ceratodon purpureus … over 10 years.
A methodology for the on-site chemical assessment of contaminant metals in soil was successfully … developed, tested and employed to facilitate the clean-up of the abandoned Thala Valley waste disposal site … at Australia’s Casey station in 2003/04.
Improved testing and remediation procedures for sites … contaminated with petroleum hydrocarbons are a priority … in remote cold regions such as Antarctica, where costs are … higher and remediation times are longer.
Long term acoustic records of underwater sound can be used to assess the timing of migrations, peak periods of … relative abundance, and seasonality and overlap of different species’ presence over large spatial scales.
The MarClim project was a four year multi-partner funded project created to investigate the effects of climatic warming on marine biodiversity. In particular the project aimed to use intertidal species, whose abundances had been shown to fluctuate with changes in climatic conditions…
Water collection and treatment is often required for effective cold regions contaminated site clean-up. Large volumes of … meltwater runoff can become contaminated during remediation activities and disperse pollutants into the surrounding environment.
Background: Poorly preserved biological tissues have become an important source of DNA for … a wide range of zoological studies. Measuring the quality of DNA obtained from these samples is … often desired; however…
A new method for estimating illegal fi shing effort is put forward. The results from this … new method are similar to those of the Agnew and Kirkwood (2005) method…
We describe the use of structured graphs for the visual exploration of biodiversity data. A graph consists of a set of nodes, representing entities of interest, linked by edges showing relationships between those entities. For biodiversity data, the nodes are typically chosen to represent taxa…
New techniques have been developed to aid in the remote sensing of type … II Polar Stratospheric Clouds (PSCs) using NASA’s MODIS (MODerate resolution … Imaging Spectroradiometer) nadir imaging satellite.
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.…
Models of variability in Adélie penguin foraging trip durations were constructed and fitted … to data collected at Béchervaise Island over a 12-year period when only natural variation … was known to occur. Variability among trips and penguins was greater in the crèche … stage…
Reduced reproductive success in flipper-banded King Penguins compared to unbanded … penguins has been reported but differences in survival were not found. The “worst-case” survival analysis done by previous researchers assumed that death occurred at the beginning … of the tail chain of absences.
IPS Radio and Space Services, currently operates three four-receiver Canadian Advanced Digital Ionosondes (CADIs), two at mid-latitudes at Canberra and Camden, and the remaining one at Casey station, Antarctica. The deployment of a fourth unit at Macquarie Island is scheduled for this summer.
A common technique for comparing the in situ microbial potential for mineralisation of petroleum hydrocarbons in different environments or under different remediation strategies, is by use of radiolabelled tracer studies.
The distribution and abundance of phytoplankton communities off east Antarctica were surveyed using CHEMTAX analysis of HPLC pigment profiles, supplemented by microscopy. Eight north--south transects … were surveyed between 80°E and 150°E, from approximately 63°S to the sea-ice, during Jan.--Mar.
