Simulated sea ice thickness in the ORCA2-LIM coupled sea ice–ocean model is … compared with thicknesses from the Antarctic Sea Ice Processes and Climate (ASPeCt) database. We find a qualitative agreement of the large-scale patterns of ice thickness … distribution.
The ‘Norfolk Meeting’ was held in November 2005 as a joint IWC SO GLOBEC initiative to … outline a program of work to expedite integrative circumpolar analyses of existing cetacean … data series for the Antarctic. Our aim was to use the results of these analyses to summarise, on a circumpolar scale…
There is much speculation over the role of frazil ice in both ocean cavities under ice shelves and in the adjacent ocean where Ice Shelf Water (ISW) plumes are found. Traditionally three-dimensional ocean circulation models have ignored this slurry of small, thin…

The Antarctic Sea Ice Processes and Climate (ASPeCt) is a program of multi-disciplinary … Antarctic sea ice zone research which is co-sponsored by the Scientific Committee on … Antarctic Research (SCAR) and the Climate and Cryosphere (CliC) program.
The efforts of Patterson and co-workers (Murozumi et al., 1969) to accurately measure Pb … concentrations in Greenland and Antarctic snow and ice produced the first reliable … determination of Pb pollution of the Earth’s polar ice sheets. Since then…
Antarctic ice is an archive of evidence of climatic conditions and natural phenomena in the … Southern Hemisphere that extends approximately one million years into the past. We can … sense changes through the concentration of atmospheric gases, stable isotope ratios, terrestrial dust levels…
Introduction: Sea ice provides a habitat for algal communities which contribute significantly to … overall primary production of the ice-covered Southern Ocean and may serve as an important … food resource for pelagic herbivores like Antarctic krill…
Conventionally the source of sea salt in the Antarctica was considered to be the ocean … surface. In simple terms, sea salt is ejected into the atmosphere as sea spray droplets, mixed … in the atmosphere, and transported to Antarctica via storm activity. Recently, however…
An ice core, drilled near the margin of the Law Dome ice cap at Cape Folger, has been analysed for trace chemical content.
From its original formulation in 1990 the International Trans-Antarctic Scientific Expedition … (ITASE) has had as its primary aim the collection and interpretation of a continent-wide array of … environmental parameters assembled through the coordinated efforts of scientists from several nations.
Monitoring includes both targeted studies designed to verify the predicted effects of specific … activities and more exploratory studies designed to detect “unknown” or unpredicted impacts. In the marine environment monitoring typically begins with an empirical experiment or survey…
Permeable reactive barriers are used to adsorb contaminants from soil water. Their fillings are granular … materials whose stability under freezing conditions has not been demonstrated. In this research, three granular materials(activated carbon…
As with human cytomegalovirus (HCMV) infection of humans, murine CMV (MCMV) infection is … widespread in its natural host, the house mouse Mus domesticus, and may consist of mixed … infection with different CMV isolates.
The invertebrate animals that inhabit ice-free areas of East Antarctica have been studied … since the earliest days of Antarctic science. However, even though biodiversity and … biogeography is reasonably well known for some regions (e.g. Southern Victoria Land)…
Studies of carbon flux and ecosystem processes require models of the population dynamics … of phytoplankton and other microbial organisms, but with over 500 protistan species known to … inhabit these waters, it is not feasible to model them individually. Instead…
Regionalisation algorithms attempt to partition a broad spatial area into discrete spatial regions, each with relatively homogeneous environmental or biotic conditions. Marine regionalisations commonly make use of data that can be represented naturally in a network context…
Sea ice is an important structuring element of Antarctic marine ecosystems and provides a vast habitat for ice-associated algae forming communities in different horizons of the ice floes.
A solar occultation sensor, the Improved Limb Atmospheric Spectrometer (ILAS)-II, measured 5890 vertical profiles of ozone concentrations in the stratosphere and lower … mesosphere and of other species from January to October 2003. The measurement latitude … coverage was 54–71°N and 64–88°S…
Polar Mesospheric Clouds (PMCs) and Polar Mesospheric Summer Echoes (PMSE) were … simultaneously observed during the 2005-2006 austral summer above Davis, Antarctica … (latitude 68.6°S). This is the first time such observations have been obtained from the … southern hemisphere.
Ground Level Enhancements (GLEs) arise when protons are accelerated to relativistic energies … at the sun, invariably associated with X-class flares, and the protons propagate to Earth and … produce statistically significant increase in ground based cosmic ray detectors.
