The total ozone column (TOC) in the 'collar' region outside the Antarctic Ozone Hole exhibits a pronounced wave-1 zonal pattern in austral spring. During the period 1979-2005, the zonal minimum of the pattern exhibited a general eastward shift of approximately 45 degrees of longitude…

During the summer of 2008/09, measurements were taken at 34 magnetotelluric (MT) stations along profiles totaling approximately 180 line km in the Prydz Bay region of Antarctica. Prydz Bay comprises several regions of coastal outcrops with distinct geological histories…

We compare thermal tropopause climatology in Arctic and Antarctic by NCEP–NCAR Reanalysis-1 data over the 1979–2008 period. The role of the troposphere and stratosphere in tropopause anomaly distribution is examined using corresponding temperature and geopotential height field.

As part of the global project ORACLE-O3 selected for the IPY, LOLITA-PSC (“Lagrangian Observations with Lidar Investigations and Trajectories in Antarctica and Arctic, of PSC”) is devoted to Polar Stratospheric Clouds (PSCs) studies. Indeed…

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…

Using the Davis (68°S, 78°E) lidar, several observing campaigns recently examined the small scale temperature structure and variability in the Antarctic winter upper troposphere and lower stratosphere (UTLS). Lidar measurements of N2 Raman backscatter were obtained over the altitude range of 8…

The diet of free-living pinnipeds is most frequently estimated through identification of otoliths, squid mouth-parts and exoskeletons … of prey in scats. This is because, although important prey types may not always be detected, sample collection is non-invasive and … analysis is easy.

The Amery Ice Shelf, East Antarctica, undergoes high basal melt rates near the southern … limit of its grounding line where 80% of the ice melts within 240km of becoming afloat. A considerable … portion of this later refreezes downstream as marine ice.

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…

It has recently been shown that sea ice (via frost flowers) is an important source of sea … salt to coastal Antarctica. This has been used to suggest that the sea salt record from … ice cores may reflect a proxy for sea ice extent around Antarctica. In this study…

As revealed by the CALIPSO orbiting lidar, the intense firestorms that occurred … in southern Australia during February 2009 injected a significant plume of … smoke particles into the lower stratosphere. Over the following weeks…

We applied a multivariate statistical modelling technique called boosted regression trees to derive relationships between environmental conditions and the distribution of the adult stage of the cyclopoid copepod Oithona similis in the Southern Ocean.

Spatial and temporal environmental variation in terrestrial Antarctic ecosystems are known to impact … species strongly at a local scale, but the ways in which organisms respond (e.g. physiologically, behaviourally) to such variation are poorly understood. Further…

Two major astronomical experiments are underway at the US Amundsen-Scott South … Pole Station. The first is the South Pole Telescope, a 10m sub-millimetre telescope de- … signed to measure primary and secondary anisotropies in the CMBR…

PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed 2.5-m optical/ … infrared telescope to be located at Dome C on the Antarctic plateau. Conditions at Dome C are known to … be exceptional for astronomy. The seeing (above ¡­30m height), coherence time…

A local scale, time dependent three-dimensional … model of the neutral thermosphere was used to test the applicability … of two previously published empirical relations between … thermospheric vertical wind and velocity divergence, i.e., those due to Burnside et al. (1981) and Brekke (1997).

The Australian Antarctic Data Centre is considering ways to modify the Biodiversity Database to improve the management of non-native species records. A new facility to associate images with species records could assist with species identification…

When resources are limited or patchy, a species may develop some degree of resource … partitioning to reduce intra-specific competition. Development of intra-specific resource partitioning … is more pronounced in species with clear phenotypic variation among individuals (e.g. age or sex).

Accurate measurement of fundamental parameters, such as temperature, density and composition, through the whole atmosphere and over long time scales is vitally important to identify and quantify changes in the earths climate, whether natural or anthropogenic.

This work contributes to the understanding of variation in methanesulphonic (MSA) concentration in an ice core … drilled during the 1996-97 Antarctic Campaign at the coastal plateau site of Talos Dome (East Antarctica)…
