The Antarctic Ice Sheet is a key feature of the global climate engine today, and has been so for most of its 35 Myr or longer history. It influences global […]
The Antarctic cryosphere has had a major effect on Cenozoic global climates, sea levels, oceanography, and Southern Hemisphere biota. Yet the climatic history of Antarctica and its contribution to global […]
A new numerical model of the high latitude ionosphere is used in conjunction with data from the EISCAT radar facility to study the formation and structure of polar patches. Inputs […]
Band-limited Pc-3 pulsations were observed on one day with pulsation magnetometers, photometers and in VLF activity at South Pole and simultaneously, electric field pulsations were observed in the ionospheric cusp […]
Twelve epipelagic copepod species were reviewed to compare their adaptations to the short primary production season and low temperatures which characterise the Southern Ocean. The species show a spectrum of […]
Longlining operations for Dissostichus eleginoides off South Georgia were assessed for interactions with seabirds and the effectiveness of measures employed by CCAMLR to mitigate seabird mortality. Following an agreement between […]
Management of the mackerel icefish (Champsocephalus gunnari) at South Georgia is complicated by the likelihood of substantial periodic variations in natural mortality rates. These may be associated with increased consumption […]
HF radar data during equinoctial, small IMF By conditions have enabled the substorm growth phase to be studied in both hemispheres. This has revealed highly conjugate behavior during the substorm […]
For activity and survival in extreme terrestrial Antarctic habitats, lithobiontic cyanobacteria depend on key biomolecules for protection against environmental stress and for optimization of growth conditions. Their ability to synthesize […]
