The Antarctic Plateau offers many benefits to astronomers, including dark and … transparent infrared skies, long periods of uninterrupted observations, and very low levels … of atmospheric turbulence. Efforts to quantify these benefits are ongoing.
Antarctic ice core records offer a key resource for understanding late Holocene climate … in the high latitude Southern Hemisphere, and potentially beyond.
All-sky imaging Fabry-Perot spectrometers can provide two dimensional maps of thermospheric wind and temperature fields over a circular region spanning around 1400 km in diameter at F-region heights, or about half this in the E-region.
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…
Ice cores from coastal East Antarctica provide highly resolved records that capture seasonal variations … in a wide range of climate proxies.
The Network for the Detection of Mesopause Change (NDMC) is a global program with the mission to promote international cooperation among research groups investigating the mesopause region (80-100km) with the goal of early identification of changing climate signals. From September 01 to October 31…
The Network for the Detection of Mesopause Change (NDMC) is a global program with the mission to promote international cooperation among research groups investigating the mesopause region (80-100 km) with the goal of early identification of changing climate signals.
The Antarctic plateau is a new frontier for … astronomy, offering superior observing … conditions to those of any other groundbased … site across most of the electromagnetic … spectrum.
PLATO (PLATeau Observatory) is the third-generation astronomical site-testing laboratory designed by the University … of New South Wales. This facility is operating autonomously to collect both scientific and site-testing data from … Dome A, the highest point on the Antarctic plateau…
Submillimetre astronomy is the prime technique to unveil the birth and early evolution of stars and galaxies in the local … and distant Universe.
PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed Australian/European optical/infrared … telescope for Dome C on the Antarctic Plateau, with target first light in 2012. The proposed telescope is 2.4m diameter, with overall focal ratio f/10…
The unique atmospheric characteristics found at Dome C on the Antarctic plateau offer significant … advantages for the operation of adaptive optics systems.
Adélie penguin (Pygoscelis adeliae) diet is an important indicator of prevailing environmental conditions and … resource availability. In this study, dietary variation within and between years was studied with fatty acid … signature analysis (FASA), stomach content analysis (SCA)…
Previous studies of Antarctic mosses … employing RAPDs have reported extraordinarily … high levels of genetic variation, even within a single … clump of moss. This is unexpected given their … extreme isolation in Antarctica and lack of sexual … reproduction. We offer an alternative explanation:
Statistically significant (at the 95% significance level) changes in daily cloud cover are … found to occur globally over land coincident with extreme increases in ‘fair-weather’ … measurements of vertical electric field (Ez) measured at Vostok, Antarctica.
Exopolysaccharides (EPSs) are high molecular weight … carbohydrate polymers that make up a substantial … component of the extracellular polymers surrounding … most microbial cells in the marine environment.
Ozone depletion has resulted in large increases in springtime ultraviolet-B radiation (UV) over Antarctic plants since the 1970s. Studies of UV induced DNA damage in three Antarctic moss species have shown Ceratodon purpureus to be the most UV-tolerant…
Summary … • Studies of ultraviolet (UV) light-induced DNA damage in three Antarctic moss … species have shown Ceratodon purpureus to be the most UV tolerant, despite … containing lower concentrations of methanol-soluble UV-screening compounds … than the co-occurring Bryum pseudotriquetrum.
Ice cores from Law Dome, in coastal East Antarctica, provide climate records that have strong connections to … the Southern Ocean and mid-latitude climate in the … Australian region. The overall climate history available from … Law Dome extends back for tens of millennia…
Many methods have been proposed for the detection of exoplanets. The minimum … detectable planetary size and mass, and the maximum distance from us at which exoplanets are … observable, are determined by both technological and environmental constraints.
We present low-resolution turbulence proles of the atmosphere above Dome C, Antarctica, measured with the MASS instrument during 25 nights in March { May 2004. Except for the … lowest layer, Dome C has signicantly less turbulence than Cerro Tololo and Cerro Pachon. In … particular…
FPGA is a potential medium for DSP implementation of direct conversion transmitters and receivers. However analog interface cannot be ruled out since amplification and other tasks are still in the analog domain. In a previous work…
Thicknesses of sea ice and snow are key variables in ice-ocean-atmosphere interactions. Sea ice insulates the warm ocean from polar air and controls the heat exchange, which is … determined by its thickness. Also, sea ice thicknesses, together with sea ice extent…
