[1] We describe a novel technique for measuring the basal melt rate at a point on an ice shelf. The method uses a phase-sensitive radar to observe the change in […]
The terrestrial biota of the Antarctic Peninsula region are experiencing marked changes in climate, especially rising temperatures, precipitation, and UV-B radiation-a combination unique worldwide. These changes, combined with the inherent […]
The oceanic islands in the Southern Ocean can be considered amongst the remotest shores as, not only are they uninhabited (except for small research stations) and geographically isolated, but they […]
There is increasing evidence supporting rapid trajectories of environmental change in the Antarctic. This study describes preliminary data on soil faunal responses to artificial environmental amelioration obtained using a ‘greenhouse’ […]
During January 2000 a baited video camera system was deployed fifteen times at depths of 719-1518 m around the Subantarctic island of South Georgia. Four species of lithodid (Anomura: Lithodidae) […]
Cephalopods (n = 515) were identified from a series of plankton and fine meshed mid-water trawls, taken between 1977 and 1999, around the British Isles. The collections were not directed […]
Three species of cirrate octopod are reported from deep-sea collections around the coasts of Greenland and Iceland in the North Atlantic. Twenty-one specimens of Stauroteuthis syrtensis were caught from east […]
Bacillus subtilis spore biological dosimeters and electronic dosimeters were used to investigate the exposure of terrestrial microbial communities in micro-habitats covered by snow and ice in Antarctica. The melting of […]
Asteroid and comet impacts on Earth are commonly viewed as agents of ecosystem destruction, be it on local or global scales. However, for some microbial communities, impacts may represent an […]
Impact craters contain ecosystems that are often very different from the ecosystems that surround them. On Earth over 150 impact craters have been identified in a wide diversity of biomes. […]
Of Martian expeditionary accomplishments, the Trans-Mars Expedition is the most audacious in terms of the logistical challenges imposed upon it and diversity of scientific foci it could encompass. The similar […]
Because of the ubiquity of subsurface microbial life on Earth, examination of the subsurface of Mars could provide an answer to the question of whether microorganisms exist or ever existed […]
