2. Tardigrades of the Australian Antarctic: Hypsibius heardensis (Eutardigrada: Hypsibiidae: dujardini group) a new species from sub-Antarctic Heard Island

   A new species, Hypsibius heardensis sp. nov. (Tardigrada: Eutardigrada: Hypsibiidae) is described from samples collected during the Australian National Antarctic Research Expeditions (ANARE) 1986-87 expedition to Heard Island, in the […]

3. Biogeological Raman spectroscopic studies of Antarctic lacustrine sediments

   Analysis of lacustrine sediments is an accepted method for deciphering the palaeoenvironment of a lake’s catchment area, as each strata of the sediment gives information about the rock type it […]

4. Molecular detection and isolation from Antarctica of methylotrophic bacteria able to grow with methylated sulfur compounds

   This study is the first demonstration that a diverse facultatively methylotrophic microbiota exists in some Antarctic locations. PCR amplification of genes diagnostic for methylotrophs was carried out with bacterial DNA […]

5. Isolation and properties of methanesulfonate-degrading Afipia felis from Antarctica and comparison with other strains of A. felis

   Three novel strains of methylotrophic Afipia felis were isolated from several locations on Signy Island, Antarctica, and a fourth from estuary sediment from the River Douro, Portugal. They were identified […]

6. Daily otolith increment validation in larval mackerel icefish, Champsocephalus gunnari

   Mackerel icefish, Champsocephalus gunnari, larvae were sampled by weekly plankton tows in Cumberland Bay South Georgia. The formation of daily growth increments in sagittal otoliths was validated from larvae sampled […]

7. Evidence against an Antarctic stratospheric vortex split during the periods of pre-IGY temperature measurements

   Historic upper-air observations from Antarctica are inspected to investigate the uniqueness of the vortex split in the Antarctic spring of 2002. No comprehensive meteorological observations are available prior to the […]

8. Sequential reduction of UV-B radiation in the field alters the pigmentation of an Antarctic leafy liverwort

   UV-B radiation (280–315 nm), incident on the leafy liverwort Cephaloziella varians growing at Rothera Point on the Western Antarctic Peninsula, was manipulated in late austral spring 1998 by screens consisting […]

9. Mackerel icefish size and age differences and long-term change at South Georgia and Shag Rocks

   This study analysed the total length (LT)-frequency distribution of mackerel icefish Champsocephalus gunnari at South Georgia and Shag Rocks from nine bottom trawl surveys at South Georgia and eight at […]

10. Flow of the West Antarctic Ice Sheet on the continental margin of the Bellingshausen Sea at the Last Glacial Maximum

    Geophysical data show that during the last glaciation the West Antarctic Ice Sheet (WAIS) drained to the continental shelf edge of the Bellingshausen Sea through a cross-shelf bathymetric trough (Belgica […]

11. Flow dynamics and till genesis associated with a marine-based Antarctic palaeo-ice stream

    Geophysical and geological data indicate that during the last glacial cycle a palaeo-ice stream drained the Antarctic Peninsula Ice Sheet (APIS) through Marguerite Bay to the edge of the continental […]

12. Planetary wave coupling from the stratosphere to the thermosphere during the 2002 Southern Hemisphere pre-stratwarm period

    Temperature observations between 20 and 120 km from the SABER instrument on the TIMED spacecraft are used to investigate the nature of planetary wave activity during the 60 days prior […]
