The Latitudinal Gradient Proiect LGP) is a successful multidisciplinary, international Antarctic … research programme. lts approach focuses on marine, terrestrial and freshwater ecosystems … along the nofth-south latitudinal gradient between nofthern Victoria Land (72 degrees S)…
The evolutionary and biogeographic history of the contemporary Antarctic terrestrial and marine biotas … reveals many components of ancient origin. For large elements of the terrestrial biota, long-term … isolation over timescales from hundreds of thousands to tens of millions of years…
The height of the atmospheric boundary layer on the Antarctic plateau is of particular interest to meteorologists and designers of optical telescopes for Antarctica. “Snodar”…
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.
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…
The unique atmospheric conditions present at sites such as Dome C on the Antarctic plateau are … very favorable for high spatial resolution astronomy. At Dome C…
Snodar is a 5 kHz monostatic acoustic radar designed to measure the atmospheric turbulence within the first 200 m of the … atmosphere with a vertical resolution of 1 m. An in situ calibration target is used to give absolute intensity calibration.
PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed 2.5-m optical/ … infrared telescope to be located at Dome C on the Antarctic plateau. Conditions at Dome C are known to … be exceptional for astronomy. The seeing (above ¡30m height), coherence time…
PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed 2.5-m optical/ … infrared telescope to be located at Dome C on the Antarctic plateau. The atmospheric conditions at Dome C … deliver a high sensitivity, high photometric precision, wide-field, high spatial resolution…

The Antarctic plateau contains the best sites on earth for many forms of astronomy, but … none of the existing bases was selected with astronomy as the primary motivation. In this paper, we try to systematically compare the merits of potential observatory sites. We include South … Pole, Domes A…
We have characterised a small, high-efficiency diesel generator selected to power remote experiments on the Antarctic … plateau at altitudes of up to 5000 m.
Terrestrial systems in Antarctica are characterized by substantial spatial and temporal variation. However, few studies have addressed the paucity of data on metabolic responses to the unpredictable … Antarctic environment, particularly with regard to terrestrial biota.
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)…
A new all-sky imaging Fabry-Perot spectrometer … has been installed at Mawson station (67360 S, 62520 E), Antarctica. This instrument is capable of recording independent … spectra from many tens of locations across the sky simultaneously. Useful operation began in March 2007…
A local scale, time dependent three-dimensional … model of the neutral thermosphere was used to test the applicability … of two previously published empirical relations between … thermospheric vertical wind and velocity divergence, i.e., those due to Burnside et al. (1981) and Brekke (1997).
Two endemic orchid species, Nematoceras dienemum and N. sulcatum, are known from sub-Antarctic Macquarie Island. Several additional orchid populations on the island are reported and cleistogamy is documented in N. dienemum for the first time. The known population sizes…
Species of the genus Pyramimonas (Prasinophyceae) are a common, widespread, but minor component of the Antarctic marine phytoplankton. They are … often associated with the seasonal sea-ice environment. Pyramimonas gelidicola … (McFadden, Moestrup & Wetherbee, 1982)…
We examine global phylogeography of the two forms of giant petrel Macronectes spp. Although previously … considered to be a single taxon, and despite debate over the status of some populations and the … existence of minimal genetic data (one mitochondrial cytochrome b sequence per form)…
Atmospheric ionization during Solar Proton Events (SPE) has traditionally … been modeled using top-of-atmosphere (TOA) particle fluxes measured by near- … Earth spacecraft, and as a consequence the modeling has been restricted to … particle energies below ¡ 500 MeV. However…
Recent model calculations have attempted to quantify the contribution of … major energetic solar cosmic ray (SCR) events to 10Be production.1,2 In this … study we compare modeled 10Be production by SCR events to measured … 10Be concentrations in a Law Dome snow pit record.
