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).
The composition of the stratosphere is driven by transport, temperatures and processes in the tropical tropopause layer – this has implications for ozone, radiation, and surface climate. The properties of the tropical tropopause layer have changed in recent decades, e.g.
The ozone hole over Antarctica is formed inside polar stratospheric vortex, which is under influence of large-scale planetary waves. The Quasi-stationary wave (QSW) in the spring Southern Hemisphere (SH)…
Antarctic ice core records offer a key resource for understanding late Holocene climate … in the high latitude Southern Hemisphere, and potentially beyond.
We present the almost complete (16,007 bp) mitochondrial genome of a Colossendeis megalonyx specimen from the Southern Ocean and discuss gene order and tRNA structure in a comparative phylogenetic context.

The 2012 ozone hole was one of the smallest since the late 1980fs due to a warmer than normal mid]lower … stratosphere over the Antarctic region this year. The development and recovery of the 2012 ozone hole will … be shown via a set of metrics based on the Ozone Monitoring Instrument (OMI)…
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)…
The Australian Antarctic Division has developed a long term coastal monitoring program at Australia’s Casey Station in East Antarctica. This evolved out of a series of field programs beginning in the mid-1990s.
Shallow-water benthic communities throughout coastal Antarctica share many species and are governed by similar physico-oceanographic processes.
La Trobe University has recently installed a new all-sky imaging Fabry-Perot spectrometer at Mawson Station, Antarctica. It is capable of recording independent spectra from many tens of locations across the sky simultaneously…
Large-etalon Fabry-Perot Spectrometers (FPS) measure upper atmosphere winds and temperatures by observing spectral profiles of atmospheric emission lines with sufficient resolution to determine the Doppler broadening, from which temperature is deduced…
