1. Postsealing genetic variation and population structure of two species of fur seal (Arctocephalus gazella and A. tropicalis)

   Commercial sealing in the 18th and 19th centuries had a major impact on the Antarctic and subantarctic fur seal populations (Arctocephalus gazella and A. tropicalis) in the Southern Ocean. The […]

2. Space Plasma Exploration by Active Radar (SPEAR): an overview of a future radar facility

   SPEAR is a new polar cap HF radar facility which is to be deployed on Svalbard. The principal capabilities of SPEAR will include the generation of artificial plasma irregularities, operation […]

3. Rapid cold hardening: a gut feeling

   This study examined the rate of cold hardening of a field population of Antarctic springtails and the effect of eating food with particular levels of ice nucleating activity on the […]

4. Survival of Heleomyza borealis (Diptera, Heleomyzidae) larvae down to -60oC

   Heleomyza borealis Boh. (Diptera, Heleomyzidae) overwinters as larvae in Arctic habitats, where they may experience winter temperatures below − 15°C. The larvae freeze at c.− 7°C but in acclimation experiments 80% survived […]

5. The effect of feeding on specific soil algae on the cold-hardiness of two Antarctic micro-arthropods (Alaskozetes antarcticus and Cryptopygus antarcticus)

   The effect of consuming terrestrial algae on the cold tolerance of two Antarctic micro-arthropods was examined. From the results of preferential feeding experiments, seven species of Antarctic terrestrial micro-algae were […]

6. Quantifying habitat use in satellite-tracked pelagic seabirds: application of kernel estimation to albatross locations

   We develop a new approach to quantifying habitat use within the foraging ranges of satellite-tracked seabirds. We applied kernel estimation techniques to 167 days (3738 locations) of data from Black-browed […]

7. History of the atmosphere from ice cores

   Ice cores are an excellent way of finding out how the atmosphere has changed because climate signals and many forcing factors for climate are present in the same core. Their […]

10. Detection and attribution of Antarctic climate change

    The current understanding of climate changes that have occurred in the last 50 years over Antarctica is presented with a focus on: (i) a summer warming of the eastern Antarctic […]

11. Efficient flowline simulations of ice-shelf/ocean interactions: Sensitivity studies with a fully coupled model

    Thermodynamic flowline and plume models for the ice-shelf/ocean system simplify the ice and ocean dynamics sufficiently to allow extensive exploration of parameters affecting ice-sheet stability while including key physical processes. […]

12. East Antarctica’s Achilles heel

    The East Antarctic ice sheet is believed to be Earth’s most stable ice sheet. Changes in geochemical composition of offshore sediments suggest that its margin repeatedly retreated by at least […]
