1. Diet and long-term changes in population size and productivity of brown skuas Catharacta antarctica lonnbergi at Bird Island, South Georgia

   Breeding ecology of brown skuas (Catharacta antarctica lonnbergi) was studied at Bird Island, South Georgia in the austral summers of 2000/2001-2003/2004. A complete census recorded 467 breeding pairs in 3.55 […]

2. A white-capped albatross, Thalassarche [cauta] steadi, at South Georgia: first confirmed record in the south-western Atlantic

   Although albatrosses typically show strong natal philopatry, a small proportion of birds emigrate to distant colonies, occasionally establishing new breeding sites and potentially initiating speciation events. Patterns of albatross distribution […]

3. Movements and burrowing activity in the Antarctic bivalve molluscs Laternula elliptica and Yoldia eightsi

   Burrowing was investigated in two Antarctic infaunal bivalve molluscs, Laternula elliptica and Yoldia eightsi, representing amongst the least and most active members of the class Bivalvia in the Southern Ocean. […]

4. Metabolic flexibility: the key to long-term evolutionary success in Bryozoa?

   Oxygen consumption (MO2) and activity were evaluated in Antarctic Bryozoa. Three species representing two different morphologies, flat sheet, laminar forms, Isoseculiflustra tenuis and Kymella polaris, and the bush form Camptoplites […]

6. Physiological flexibility: the key to success and survival for Antarctic fairy shrimps in highly fluctuating extreme environments

   1. The anostracan fairy shrimp Branchinecta gaini inhabits one of the most hostile environments on earth, living in pools and lakes in Antarctica. Between January 2002 and January 2003 temperatures […]

7. The UV environment of the Beagle 2 landing site: detailed investigations and detection of atmospheric state

   December 25th 2003 will see the Beagle 2 lander arrive at the surface of Mars in the Isidis region, allowing for the first time in situ measurements of ultraviolet (UV) […]

8. Magnetic local time, substorm, and particle precipitation-related variations in the behaviour of SuperDARN Doppler spectral widths

   Super Dual Auroral Radar Network (DARN) radars often detect a distinct transition in line-of-sight Doppler velocity spread, or spectral width, from 200 m s(-1) at higher latitude. They also detect […]

9. Additions and corrections to the lichens of Antarctica and South Georgia

   The taxonomic listing given in Lichens of Antarctica and South Georgia (Øvstedal & Lewis Smith 2001) has been updated. 17 additional taxa of lichenised fungi are described, including several nomenclatural […]

10. A ‘low-level’ explanation for the recent large warming event trend over the western Antarctic Peninsula involving blocked winds and changes in zonal circulation

    [1] We demonstrate a mechanism whereby the impact of stronger circumpolar westerly winds on the mountains of the Antarctic Peninsula contributes significantly to the enhanced warming trend observed over its […]

11. Prydz Bay fan and the history of extreme ice advances in Prydz Bay

    During the late Neogene, the Lambert Glacier–Amery Ice Shelf drainage system flowed across Prydz Bay in an ice stream that reached the shelf edge and built a trough mouth fan […]

12. The impact of PMSE and NLC particles on VLF propagation

    PMSE or Polar Mesosphere Summer Echoes are a well-known phenomenon in the summer northern polar regions, in which anomalous VHF/UHF radar echoes are returned from heights similar to85 km. Noctilucent […]
