The parties to the Montreal Protocol are informed by three panels of experts. One of these is the … Environmental Effects Assessment Panel (EEAP), which deals with two focal issues. The first focus is … the effects of increased UV radiation on human health, animals, plants, biogeochemistry…
Although huddling was shown to be the key by which emperor penguins (Aptenodytes forsteri) save energy and sustain their breeding fast … during the Antarctic winter, the intricacies of this social behavior have been poorly studied.

Bromine explosion events that occur over first year sea ice in the polar spring cause mercury deposition and dramatically alter the oxidative capacity of the polar boundary layer. Atmospheric chemical measurements made during the Sea Ice Physics and Ecosystems eXperiment (SIPEX II)…
Results from the chemistry—atmosphere—climate model version of the Australian Community Climate and Earth System Simulator (ACCESS) are presented. ACCESS is based on the UK Met Office Unified Model version 7.3 (UM 7.3) including the United Kingdom Chemistry and Aerosols (UKCA) module.
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…

Antarctic ice core records offer a key resource for understanding late Holocene climate … in the high latitude Southern Hemisphere, and potentially beyond.
The pycnogonids of the Southern Ocean have been studied for almost two centuries and have played a key role in shaping previous biogeographic regions for the Antarctic benthos.
The joint TOT-Cal / CryoVExANT2011 project contributes to the validation of the CryoSat-2 altimetry mission through investigations of a key portion of the East Antarctic ice sheet near Australia’s Casey Station. Spanning parts of Law Dome and the Totten Glacier…
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 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.
Sub-Antarctic islands are the only landmasses between Antarctica and South America, Africa and Australia where terrestrial climate and ecosystem records are available, making them crucial locations for linking southern mid and high latitude regions. However…
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.
For Emperor penguins (Aptenodytes forsteri), huddling is the key to survival during the Antarctic winter. Penguins in a … huddle are packed so tightly that individual movements become impossible, reminiscent of a jamming transition in … compacted colloids. It is crucial, however…
The Antarctic has experienced major changes in temperature, wind speed and stratospheric ozone levels during the last 50 years. However until recently continental Antarctica appeared to be little impacted by climate warming, thus biological changes were predicted to be relatively slow.
