Polar Stratospheric Cloud (PSC) composition class information is extracted from the Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) curtains for four Antarctic PSC seasons (2007 - 2010) and four Arctic PSC seasons (2006/07 - 2009/10). Orographic gravity wave (OGW)…
The 2013 ozone hole was relatively small, with about 15-17 ozone holes out of the last 20 (1994-2013) having been bigger/deeper (depending on the metric used), and only 2-4 having been smaller (2002, 2004, 2010, 2012).
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 cause of seasonal trends in the zonal asymmetry of the total ozone column (TOC) at high southern latitudes are examined. Using ERA-Interim assimilated meteorological data, we examine characteristics of extra-tropical Rossby waves…
Links between changes in the southern polar stratosphere and tropospheric climate have been identified in both modelling and observational studies, highlighting the importance of an accurate stratosphere in climate models. However…
We use a set of metrics for the polar atmosphere to compare coupled ocean-atmosphere general circulation models (AOGCMs) experiments for the 5th Coupled Model Intercomparison Project (CMIP5) with results from chemistryclimate models (CCMs) of the 2nd Chemistry-Climate Model Validation (CCMVal-2)…
Antarctic krill (hereafter krill) is the key species of the Antarctic marine ecosystem as well as a target of commercial fishery in the Southern Ocean, which compels careful predictions about potential impacts of Ocean Acidification (OA)…
This paper aims to provide the overview needed to include krill in food-web models and to guide modellers to key sources of data. It describes the strengths of each method of sampling krill, i.e. with nets (for historical time series, demographic information and live krill), acoustics (distribution…
Protection of the wilderness and aesthetic values of Antarctica is mandated by the Protocol on Environmental Protection to the Antarctic Treaty, the “Madrid Protocol,” which came into force in 1998. Despite the passage of over 13 years…

Antarctic ice core records offer a key resource for understanding late Holocene climate … in the high latitude Southern Hemisphere, and potentially beyond.
This study aimed to describe the migratory distribution and behaviour of pygmy blue whales … that feed in the Perth Canyon region off the coast of Western Australia.
CryoSat-2 was launched in April 2010, as part of the European Space agency's (ESA) Earth Opportunity Programmes.
The TotCal / CryoVExANT2011 project is an Australian and German collaboration that contributes to the validation of the CryoSat-2 radar altimetry mission through investigations of a key portion of East Antarctica near the Australian Casey Station.

The origins and evolution of sub-Antarctic island floras are not well understood. In particular there is … uncertainty about the ages of the contemporary floras and the ultimate origins of the lineages they contain. Pringlea R. Br. (Brassicaceae)…
For many species trophic interactions are difficult to study because of their cryptic habits and/or the unfavourable characteristics of samples for traditional diet techniques. DNA-based diet techniques are sensitive…
