1. Kelp degradation by Paractora trichosterna (Thomson) (Diptera: Helcomyzidae) at sub-Antarctic South Georgia

   The Diptera are one of the dominant insect consumer groups on sub-Antarctic islands and are thought to contribute significantly to terrestrial ecological processes at many of these islands. The life-cycle […]

3. Origin and composition of settling iron aggregates in oligotrophic Sombre Lake, Signy Island, Antarctica

   Sediment traps were deployed in an oligotrophic, seasonally anoxic maritime Antarctic lake for 15 months. Immediately after the onset of the inflow in spring many iron oxyhydroxide aggregates were collected […]

4. Taxonomy and palaeoecology of Early Cretaceous (Late Albian) angiosperm leaves from Alexander Island, Antarctica

   Seven species of angiospermous leaves from the mid to Late Albian of Alexander Island, Antarctica provide further evidence of angiosperm radiation into high southern palaeolatitudes. The leaves have both palmate […]

6. Moult in relation to some aspects of reproduction and growth in swarms of Antarctic krill,Euphausia superba

   In a 14-d period 38 swarms of Antarctic krill,Euphausia superba Dana, were sampled in an area 55.5 x 55.5 km to the southwest of Elephant Island, at the north of […]

8. In situ photosynthesis and estimated annual production of the red macroalga Myriogramme mangini in relation to underwater irradiance at Signy Island (Antarctica)

   For the first time, photosynthesis of Myriogramme mangini (Gain) Skottsberg, one of the dominant red macroalgae in the sublittoral of Signy Island (South Orkney Islands), was studied in situ under […]

9. A downward developing mesoscale cyclone over the Ross Ice Shelf during Winter

   A case of midtropospheric mesoscale cyclone formation and downward development adjacent to and over the Ross Ice Shelf, Antarctica during May 1988 is presented. This event involved atmospheric phenomena over […]

10. Acoustic targets at South Georgia and the South Orkney Islands during a season of krill scarcity

    Dual frequency (38 and 120 kHz) acoustic surveys of shelf-break regions in the vicinity of the Willis Islands, South Georgia, and Coronation Island, South Orkneys, both in the Atlantic sector […]

11. Status of southern elephant seals at South Georgia

    Approximately 54% of the world population of southern elephant seals (Mirounga leonina) breeds at South Georgia. A partial survey in 1951 and a complete survey in 1985, together with counts […]

12. Dive durations in pinnipeds and seabirds

    Many endothermic divers regularly exceed the theoretical limit to the duration of aerobic dives, suggesting that assumptions about either the oxygen storage capacity of tissues or the metabolic rate of […]
