1. Numerical weather prediction model performance over high southern latitudes

   Increasingly, output from numerical weather prediction (NWP) models is being used for real-time weather forecasts for the Antarctic and for Antarctic-related climate diagnostics studies. Evidence is presented that indicates that […]

2. Reduced oxygen at high altitude limits maximum size

   The trend towards large size in marine animals with latitude, and the existence of giant marine species in polar regions have long been recognized, but remained enigmatic until a recent […]

3. Bacterioplankton community diversity in a maritime Antarctic lake, determined by culture-dependent and culture-independent techniques

   The biodiversity of the pelagic bacterioplankton community of a maritime Antarctic freshwater lake was examined by cultivation-dependent and cultivation-independent techniques to determine predominant bacterioplankton populations present. The culture-dependent techniques used […]

4. Viruses in Antarctic ecosystems

   This review seeks to highlight the potential importance of viruses in Antarctic ecosystems and describe the limited scope of Antarctic virus studies to date, including studies of marine, terrestrial and […]

5. Bacterioplankton community structure in a maritime Antarctic oligotrophic lake during a period of holomixis, as determined by denaturing gradient gel electrophoresis (DGGE) and fluorescence in situ hybridization (FISH)

   The bacterioplankton community structure in Moss Lake, a maritime Antarctic oligotrophic lake, was determined with vertical depth in the water column, during the ice-free period on Signy Island in the […]

6. On the lifetime and extent of an auroral westward flow channel (AWFC) observed during a magnetospheric substorm

   A -190-nT negative bay in the geomagnetic X component measured at Macquarie Island (-65degreesA) showed that an ionospheric substorm occurred during 09:58 to 11:10 UT on 27 February 2000. Signatures […]

7. Chronological study of the pre-Permian basement rocks of southern Patagonia

   Small outcrops of the basement of the Deseado Massif, consisting of weathered, altered granitoids and their metasedimentary host rocks, were dated by the U-Pb zircon method using thermal ionization mass […]

8. Antiquity of the Rio de la Plata craton in Tandilia, southern Buenos Aires province, Argentina

   Rb-Sr and Sm-Nd whole-rock data for granitoids and orthogneisses from the western part of the Sierras Septentrionales of the southern Buenos Aires province yield an errorchron of 2009 +/- 71 […]

10. Schistidium deceptionense, a new moss species from the South Shetland Islands, Antarctica

    Schistidium is the richest moss genus in the Antarctic consisting of twelve species, one of which, S. deceptionense Ochyra, Bednarek-Ochyra, & Lewis Smith, is here described as new to science […]

11. Palaeo-ice streams, trough mouth fans and high-latitude continental slope sedimentation

    The classical model of trough mouth fan (TMF) formation was developed in the Polar North Atlantic to explain large submarine fans situated in front of bathymetric troughs that extend across […]

12. Oxygen-isotope (delta18O) evidence of Holocene hydrological changes at Signy Island, maritime Antarctica

    A record of Holocene hydrological changes has been produced from variations in oxygen-isotope composition (delta(18)O) preserved in freshwater lake sediments from maritime Antarctica. Small amounts (
