UV-B screening potential is higher in two cosmopolitan moss species than in a co-occurring Antarctic endemic moss - implications of continuing ozone depletion Global Change Biology, 2006 (Ref: 12867)
Category 1: Peer-reviewed literature

Concentrations of UV-B absorbing pigments and anthocyanins were measured in three moss species, over a summer growing season in Antarctica. Pigment concentrations were compared with a range of climatic variables to determine if there was evidence that pigments were induced by UV-B radiation…

A review of optical sky brightness and extinction at Dome C, Antarctica. Publications of the Astronomical Society of the Pacific, 2006 (Ref: 12300)
Category 1: Peer-reviewed literature

The recent discovery of exceptional seeing conditions at Dome C, Antarctica, raises the possibility … of constructing an optical observatory there with unique capabilities. However, little is known from an astronomer’s … perspective about the optical sky brightness and extinction at Antarctic sites.

Modeling M2 tidal variability in Arctic sea-ice drift and deformation Annals of Glaciology, 2006 (Ref: 12850)
Category 1: Peer-reviewed literature

Semi-diurnal oscillations are a ubiquitous feature of polar sea-ice motion. Over much of the … Arctic basin, inertial and semi-diurnal tidal variability have similar frequencies so that periodicity alone … is inadequate to determine the source of oscillations.

Antarctic sea-ice velocity as derived from SSM/I imagery Annals of Glaciology, 2006 (Ref: 12849)
Category 1: Peer-reviewed literature

Sea-ice velocities derived from remotely sensed microwave imagery of the Special Sensor … Microwave/Imager (SSM/I) have been analyzed for changes over time in Antarctic sea-ice velocity, for … the period 1988–2004.

Meteor radar temperatures estimation using the Davis MST and meteor radars. Proceedings of MST11: Eleventh International Workshop on Technical & Scientific Aspects of MST radar, Gadanki/Tirupati, India, 11-15 December 2006, 2006 (Ref: 12784)
Category 3: Abstract

This paper presents the meteor temperatures estimated using two radars installed … in Davis (69 deg S, 78 deg E), Antarctica. The Davis MST radar was installed in … February 2003, primarily for observation of polar mesosphere summer echoes…

Antarctic meteor observations using the Davis MST and meteor radars. Proceedings of the 36th COSPAR Scientific Assembly, Beijing, China 16-23 July 2006., 2006 (Ref: 12626)
Category 3: Abstract

This paper presents the meteor observations using two radars installed in Davis (69 … deg S, 78 deg E), Antarctica. The Davis MST radar was installed in February 2003, primarily for observation of polar mesosphere summer echoes…

Nitrogen isotope constraints on subantarctic biogeochemistry. Journal of Geophysical Research, 2006 (Ref: 12708)
Category 1: Peer-reviewed literature

We report nitrate (NO3) nitrogen isotope ratios for seawater samples collected in the … Subantarctic Zone of the Southern Ocean during both winter and summer as part of the … Australian Antarctic CRC Subantarctic Zone (SAZ) Project.

Physiological traits of organisms in a changing environment. Trends in Antarctic Terrestrial and Limnetic Ecosystems: Antarctica as a Global Indicator., 2006 (Ref: 12834)
Category 1: Peer-reviewed literature

Antarctic ecosystems represent one extreme of the continuum of environmental … conditions across the planet. To our eyes, the environment appears harsh but, even … though terrestrial biological diversity is restricted, a wide range of life is present … and, locally, thrives. In the Antarctic…

UV-B screening potential is higher in two cosmopolitan moss species than in a co-occurring Antarctic endemic ? implications of continuing ozone depletion. Abstracts of the Combio 2006 Conference, Brisbane Sept 24-28th 2006., 2006 (Ref: 12837)
Category 3: Abstract

Concentrations of UV-B absorbing pigments and anthocyanins were measured in three moss species, over a summer growing season in Antarctica. Significant seasonal differences were found in the potential UV-B screening pigments. The most exposed species, Ceratodon purpureus…

Watching moss grow: radiocarbon reveals growth rate of Antarctic mosses. Abstracts of the SCAR Open Science Conference, Hobart, 12-14 July 2006., 2006 (Ref: 12836)
Category 3: Abstract

Antarctica is both the coldest and most arid continent on Earth, and experiences continuous … light in midsummer and continuous darkness in midwinter. These factors reduce the growth … rate of the continental Antarctic flora (mosses, lichens and algae) to a minimum.

How will climate change affect Antarctic moss species? Abstracts of the SCAR Open Science Conference, Hobart, 12-14 July 2006., 2006 (Ref: 12835)
Category 3: Abstract

Antarctica has been exposed to increases in ultraviolet-B (UV-B) radiation as a result of … ozone depletion for several decades. In addition, climate change will alter temperature and … water availability to plant communities over the next century. Recent studies…

Category 1: Peer-reviewed literature

Antarctic bryophyte communities presently tolerate physiological extremes in water availability, surviving both desiccation and submergence events.

Climate change manipulations show Antarctic flora is more strongly affected by elevated nutrients than water. Global Change Biology, 2006 (Ref: 12682)
Category 1: Peer-reviewed literature

Climate change is expected to affect the high latitudes first and most severely, rendering … Antarctica one of the most significant baseline environments for the study of global … climate change. The indirect effects of climate warming…
