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…
Several fuel spills have occurred on subantarctic Macquarie Island (548300 S 1588570 E) associated with storing fuel and … generating power for the island’s research station. The Australian Antarctic Division began full-scale, on-site remediation of these sites … in 2009.
While definitive winter measurements for Dome C must await until 2004, on the basis of existing data the Antarctic … Dome sites promise the best conditions on the Earth for many astronomical observations. Because atmospheric … turbulence is largely confined to a ~ 100 m ground layer…
Considerable progress in our understanding of the causes of polar stratospheric ozone loss has been made during the past two decades. However, model calculations are still limited by uncertainties in both chemical and dynamical factors.
The ozone loss simulated with climate models is based on laboratory kinetic data. These laboratory data are difficult to conduct at stratospheric pressures and temperatures and there is substantial uncertainty surrounding these parameters.
Sensitive analytical techniques are typically required when dealing with samples from Antarctica as even … low concentrations of contaminants can have detrimental environmental effects. Magnetic Sector ICP-MS is … an ideal technique for environmental assessment as it offers high sensitivity…
Avian and mammalian predators play a key role in the Kerguelen Plateau ecosystem, both with respect to structuring the marine community and its response to anthropogenic influences, such as climate change and commercial fisheries.
Data from a new regional airborne geophysical survey (ICECAP) has transformed our appreciation of the topography … and glaciology associated with the Aurora Subglacial Basin in East Antarctica. Using these data in conjunction … with numerical ice sheet modelling…
Networks – structured graphs consisting of sets of nodes connected by edges – provide a rich framework … for data visualisation and exploratory analyses. Although rarely used for the visualisation of ecological … data, networks are well suited to this purpose…
resulted in devastating bushfires igniting in south-eastern Australia. As a result, a significant amount of smoke aerosols was injected into the upper troposphere-lower stratosphere (UTLS) region. Its properties, in particular H2O enhancement inside the smoke plume…
1. The likelihood that seabirds will be hooked and drowned in longline fisheries increases when baited hooks sink slowly. Fishermen target different fishing depths by setting the mainline through a line shooter, which controls the tension (or slackness) in the line.
Ice cores from coastal East Antarctica provide highly resolved records that capture seasonal variations … in a wide range of climate proxies.
Zonal asymmetry in quasi-stationary ozone distribution is considered in the latitude range 50-80S using satellite total ozone data. Amplitude of the quasi-stationary wave has been determined as a half-difference between maximal and minimal values in 3-month averaged ozone distribution. Besides…
The high-spatial-resolution observations of the auroral … E-region echoes by the Super Dual Auroral Radar Network … (SuperDARN) HF radar at Pykkvibaer, Iceland considered … in a previous study are re-examined.
We analyze the precursor of a Forbush decrease (FD) observed with the Global Muon Detector Network on 2006 … December 14. An intense geomagnetic storm is also recorded during this FD with the peak Kp index of 8+.
Tracking features between pairs of satellite synthetic aperture radar (SAR) images using image crosscorrelation … methods is a powerful tool for defining regions of image movement such as ice flow of Antarctic … glaciers. Unlike optical images…
The atmospheric conditions above Dome A, a currently unmanned location at the highest point on … the Antarctic plateau, are uniquely suited to astronomy. For certain types of astronomy Dome A is … likely to be the best location on the planet…
We have characterised a small, high-efficiency diesel generator selected to power remote experiments on the Antarctic … plateau at altitudes of up to 5000 m.
Changes in buoyancy during an animal’s time at sea are a powerful tool for inferring … spatial and temporal foraging success. Buoyancy can be difficult to measure, but in some species of … seal, drift components of dives can be used.
The mantis shrimps (Stomatopoda) are quintessential marine predators. The combination of powerful raptorial appendages … and remarkably developed sensory systems place the stomatopods among the most effi cient invertebrate predators.
PLATO (PLATeau Observatory) is the third-generation astronomical site-testing laboratory designed by the University … of New South Wales. This facility is operating autonomously to collect both scientific and site-testing data from … Dome A, the highest point on the Antarctic plateau…
Over a decade of site testing in Antarctica has shown that both South Pole and Dome C are exceptional sites for … astronomy, with certain atmospheric conditions superior to those at existing mid-latitude sites. However, the highest … point on the Antarctic plateau, Dome A…
We study two intense Forbush decreases that occurred during two adjacent SOLTIP (Solar connection of Transient Interplanetary … Processes) intervals; namely SOLTIP 1 (22–27 March 1991) and SOLTIP 2 (1–17 June 1991)…
