Remnants of Early Archaean rocks (>FX3000 m.y. old) are reported from most continents. A critical review of the radiometric data shows that few of these are well authenticated and most […]
Following growth under sub-optimal concentrations of nutrients, cells ofChlorella emersonii accumulated lipid and became more resistant to the damage caused by freezing and thawing. These results suggest that the factor […]
Temperatures from 10 m bore holes have been analysed to determine the spatial variation of mean annual surface temperature over the Antarctic Peninsula. In general there is a decrease in […]
The concentrations and distributions of alkanes have been determined in samples of sediment, fish, benthos and a land plant mixture from King Edward Cove, South Georgia. The fish muscle and […]
A major rockfall occurred near the summit of Paulsen Peak (1877 m) and initiated a slide of rock, firn, and ice debris 4 km down the Lyell Glacier, South Georgia, […]
In the calculation of atmospheric total ozone from ultraviolet spectrometry, the particulate scattering term is usually regarded as a linear function of wavelength. A method due to R. E. Basher, […]
1. Rising human activity in Antarctica, combined with continued warming of the polar climate, means the risk of non‐native terrestrial species colonising and establishing in its biodiversity‐ and nutrient‐poor ecosystems […]
Antarctica is isolated, surrounded by the Southern Ocean, and has experienced extreme environmental conditions for millions of years, including during recent Pleistocene glacial maxima. How Antarctic terrestrial species might have […]
In the Southern Ocean the Antarctic Circumpolar Current is significantly steered by large topographic features, and sub-polar gyres form in their lee. The geometry of topographic features in the Southern […]
