Background: Free ocean CO2 enrichment experiments (FOCE) were developed to address the need for information on community level response to ocean acidification in natural habitats. The antFOCE project was the first polar FOCE system and was run at Casey Station, East Antarctica…
Better characterisation of aerosol processes in pristine, natural environments, such as Antarctica, have recently been shown to lead to the largest reduction in uncertainties in our understanding of radiative forcing.
Aerosol observations above the Southern Ocean and Antarctic sea ice are scarce. Measurements of aerosols and atmospheric composition were made in East Antarctic pack ice on-board the Australian icebreaker Aurora Australis during the spring of 2012.

Polar communities are expected to experience the impacts of ocean acidification sooner and more heavily than other regions, and serve as indicators of the consequences we can expect from increasing ocean CO2 concentrations.
We review the 2012 Antarctic ozone hole, making use of various meteorological … reanalyses, remotely sensed ozone measurements and ground-based measurements … of ultra-violet radiation. Based on analysis of 33 years of satellite records…
1.Ecosystem change is predicted to become more prevalent with climate change. Widespread dieback of cushion plants and bryophytes in alpine fellfield on Macquarie Island may represent such change. Loss of the keystone endemic cushion plant, Azorella macquariensis…
Two sets of historical 3-ensemble simulations have been obtained with versions 1.0 and 1.3 of the Australian Community Climate and Earth System Simulator (ACCESS) to examine the effects of ozone change since 1960.
The Antarctic ozone hole of 2011 is reviewed from a variety of perspectives, making … use of various data and analyses. The ozone hole of 2011 was relatively large … in terms of maximum area, minimum ozone level and total ozone deficit…
Understanding the sensitivities of Antarctic organisms to metal exposure is essential when developing protective environmental quality criteria for Antarctica. This study takes a community based approach to determine the potential effects of metal contamination on coastal Antarctic zooplankton.
Passive acoustic tracking of blue whales has been proposed as a key component in a strategy to obtain a circumpolar abundance for Antarctic blue whale as proposed in a project of the IWC Southern Ocean Research Partnership.
The Antarctic plateau provides the best terrestrial sites for infrared and sub-millimetre astronomy. In this paper we examine the relative importance of temperature…
