A climatology of hydroxyl (6-2) band temperatures has been derived from 15 consecutive years of scanning … spectrometer measurements at Davis station (68°S, 78°E), Antarctica.
The association between Southern Hemisphere cyclones and anticyclones and the El Niño–Southern … Oscillation (ENSO), southern annular mode (SAM), Antarctic sea ice extent (SIE), and rainfall in Perth … and Melbourne is explored. Those cities are, respectively…
Two major astronomical experiments are underway at the US Amundsen-Scott South … Pole Station. The first is the South Pole Telescope, a 10m sub-millimetre telescope de- … signed to measure primary and secondary anisotropies in the CMBR…
The atmospheric conditions above Dome A, a currently unmanned location at the highest point on … the Antarctic plateau, are uniquely suited to astronomy. For certain types of astronomy Dome A is … likely to be the best location on the planet…
A climatological mean distribution for the surface water pCO2 over the global oceans in non-El Niño conditions has been constructed with spatial resolution of 4° (latitude) ×5° (longitude)…
Temperature data from the COSMIC GPS-RO … satellite constellation are used to study the distribution and … variability of planetary wave activity in the low to midstratosphere … (15–40 km) of the Arctic and Antarctic from … September 2006 until March 2009.
Polar stratospheric gravity wave activity is studied using data from the Constellation … Observing System for Meteorology, Ionosphere and Climate (COSMIC) Global … Positioning System Radio Occultation (GPS-RO). Waves with vertical wavelengths of … 2 to 15 km are considered.
Ozone hole over Antarctica exists almost three decades each austral spring.
The zonal anomalies data in total ozone and thermal tropopause height … shows that ozone depletion during austral spring has a strong influence on … the height and sharpness of the tropopause over West Antarctica.
The Antarctic environment poses both physical and … psychological challenges to human performance, particularly during the austral winter. Additionally, Antarctic employment involves prolonged separation … from existing social support networks.
The natural variability of the Weddell Sea variety of Antarctic Bottom Water (AABW) is examined in … a long-term integration of a coupled climate model. Examination of passive tracer concentrations suggests … that the model AABW is predominantly sourced in the Weddell Sea.
We highlight the operational challenges and planned solutions faced by an optical observatory taking advantage of the … superior astronomical observing potential of the Antarctic plateau. Unique operational aspects of an Antarctic optical … observatory arise from its remoteness…
We present the Gattini project: a multisite campaign to measure the optical sky properties above the two high altitude … Antarctic astronomical sites of Dome C and Dome A. The Gattini-DomeC project, part of the IRAIT site testing … campaign and ongoing since January 2006…
The Antarctic Plateau contains sites with the potential to be the best in the world for many astronomical observations. The Plateau has strong advantages in the waveband between thermal-IR and millimetre-waves, for time-based astronomy, and for adaptive optics and interferometry.
ABSTRACT. The PLATeau Observatory (PLATO) is an automated self-powered astrophysical observatory that … was deployed to Dome A, the highest point on the Antarctic plateau, in 2008 January.
In the light of the predicted global climate change, it is essential that the status and … diversity of polar microbial communities is described and understood. In the … present study, molecular tools were used to investigate the marine eukaryotic … communities of Prydz Bay, Eastern Antarctica…
In 2008, the emperor penguin Aptenodytes forsteri colony at Amanda Bay, East Antarctica, was … designated an Antarctic Specially Protected Area by the 31st Antarctic Treaty Consultative Meeting in Kyiv, Ukraine.
We present a computational model of the largescale … cumulative light exposure of sea ice in the Southern … Ocean off East Antarctica (30E–150E). The model uses … remotely sensed or modelled sea ice concentration, snow … depth over sea ice, and solar irradiance data…
In September–October 2005, the juxtaposition of low- and high-pressure anomalies at … 130W and 60W, respectively, created strong and persistent northerly airflow across the … West Antarctic Peninsula (WAP). This had a major impact on regional sea ice conditions…
Ice cores provide a suite of proxy variables which respond to potentially complex and non-linear interactions between … many climatic and environmental variables. This complexity can obscure identification of links between ice core … measurements and classical climate variables.
