1. An energy–distance trade-off in a central-place forager, the Antarctic fur seal (Arctocephalus gazella)

   We tested the prediction that lactating fur seals (Arctocephalus gazella) at South Georgia will take prey of greater energy density with increasing distance of foraging from the colony. The study […]

2. Statistical relations between the probability of occurrence of Pc3-4 pulsations at high latitudes in the Antarctic regions and the solar wind and IMF parameters

   Geomagnetic pulsation in the Pc3–4 bands have been studied at high Antarctic latitudes during the local summer. The statistical relation between the occurrence probability of Pc3 and Pc4 pulsations and […]

3. Hypoxia tolerance associated with activity reduction is a key adaptation for Laternula elliptica seasonal energetics

   Seasonal dormancy is a widespread mechanism for reducing energy expenditure during periods of low energy availability. Seasonal variation in activity and the cost of pumping water through the siphons were […]

4. Neogene environmental history deduced from glacigenic sediments on James Ross Island, northern Antarctic Peninsula

   The stability, configuration and volume of the Cenozoic Antarctic Ice Sheet (AIS) are poorly known and contentious. Our investigation of late Neogene glacial and interglacial sediments from James Ross Island, […]

5. Jurassic magmatism in Dronning Maud Land: synthesis of results of the MAMOG project

   The Jurassic Karoo large igneous province (LIP) of Antarctica, and its conjugate margin in southern Africa, is critical for investigating important questions about the relationship of basaltic LIPs to mantle […]

6. Segregation between the sexes: Antarctic fur seals, Arctocephalus gazella, foraging at South Georgia

   Antarctic fur seals show extreme sexual size dimorphism and their breeding strategies place very different constraints on the behaviour of males and females. Whereas the foraging behaviour of lactating females […]

7. How well do we know the Antarctic marine fauna? A preliminary study of macroecological and biogeographical patterns in Southern Ocean gastropod and bivalve molluscs

   The aim of this study was to use data for gastropod and bivalve molluscs to determine whether the fauna of the Southern Ocean is sufficiently well known to establish robust […]

8. Satellite tracking and diving behaviour of sub-adult narwhals (Monodon monoceros) in Svalbard, Norway

   Three juvenile narwhals captured during August 1998 in the northeast of Svalbard, Norway, were equipped with satellite-relayed data loggers (SRDLs) that transmitted diving and swim-speed data, in addition to location, […]

9. Borehole optical stratigraphy and neutron-scattering density measurements at Summit, Greenland

   We have made side-by-side measurements in several boreholes at Summit, Greenland, using borehole optical stratigraphy (BOS) and neutron-scattering density logging techniques. The BOS logs show strong positive correlation at shallow […]

10. The effects of rotation and ice shelf topography on frazil-laden ice shelf water plumes

    A model of the dynamics and thermodynamics of a plume of meltwater at the base of an ice shelf is presented. Such ice shelf water plumes may become supercooled and […]

11. Diversity and biogeography of the Antarctic flora

    Aim To establish how well the terrestrial flora of the Antarctic has been sampled, how well the flora is known, and to determine the major patterns in diversity and biogeography. […]

12. Antarctic Peninsula sea levels: A real-time system for monitoring Drake Passage transport

    Sub-surface pressure (SSP) data from tide gauges at three bases on the Pacific coast of the Antarctic Peninsula, together with SSP information from a bottom pressure recorder deployed on the […]
