1. Acoustic estimates of krill density at South Georgia, 1981 to 1998

   Acoustic estimates of densities of Antarctic krill, Euphausia superba, at South Georgia during 11 austral summers between 1981 and 1998 are presented. Krill density at the island fluctuated widely from […]

2. An analysis of temporal variability in abundance, diversity and growth rates within the coastal ichthyoplankton assemblage of South Georgia (sub-Antarctic)

   The study of spatial and temporal distribution and diversity of ichthyoplankton (fish eggs and larvae) can provide fisheries-independent information on the population dynamics and recruitment processes of marine fish species. […]

3. Concordance of interannual fluctuations in acoustically estimated densities of Antarctic krill around South Georgia and Elephant Island: biological evidence of same-year teleconnections across the Scotia Sea

   Acoustic estimates of the densities of Antarctic krill, Euphausia superba, in areas around South Georgia (SG) and Elephant Island (EI) were compared for seven austral summers between 1981 and 1997. […]

5. Potential for long-distance dispersal of Euphausia crystallorophias in fast current jets

   The euphausiid Euphausia crystallorophias Holt and Tattersall, 1906 is considered to be a neritic species. It has been found in greatest abundance along the Antarctic continental margins, often in association […]

6. A comparison of Antarctic euphausiids sampled by net and from geothermally heated waters: insights into sampling bias

   The Antarctic euphausiids Euphausia superba and E. crystallorophias were sampled using an 8 m2 rectangular midwater trawl inside the caldera of Deception Island. Specimens of the same species were collected on […]

7. Late Jurassic tethyan ancestry of Recent southern high-latitude marine isopods (Crustacea, Malacostraca)

   Isopods are one of the key marine groups that radiated extensively in the southern high-latitude regions, and it is widely assumed that they did so essentially through the Cenozoic era. […]

8. The shelf break front to the east of the sub-Antarctic island of South Georgia

   The sub-Antarctic island of South Georgia lies in polar waters to the south of the Polar Front and is influenced by the Weddell Scotia Confluence whose waters reach the island’s […]

9. Spatial dynamics of two introduced species of carabid beetles on the sub-Antarctic island of South Georgia

   On the sub-Antarctic island of South Georgia two species of predatory beetle, Trechisibus antarcticus and Oopterus soledadinus (Coleoptera, Carabidae), were accidentally introduced. The colonisation process offers unique opportunities for testing […]

10. Heart rate and behaviour of fur seals: implications for measurement of field energetics

    Archival data loggers were used to collect information about depth, swimming speed, and heart rate in 23 free-ranging antarctic fur seals. Deployments averaged 9.6 ± 5.6 days (SD) and totaled […]

11. Heart rate and estimated energy expenditure of flapping and gliding in black-browed albatrosses

    Albatrosses are known to expend only a small amount of energy during flight. The low energy cost of albatross flight has been attributed to energy-efficient gliding (soaring) with sporadic flapping, […]

12. The links between large igneous provinces, continental break-up and environmental change: evidence reviewed from Antarctica

    Earth history is punctuated by events during which large volumes of predominantly mafic magmas were generated and emplaced by processes that are generally accepted as being, unrelated to ‘normal’ sea-floor […]
