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 […]
Hydrothermal vents at the East Scotia Ridge (ESR) were the first vents to be visually confirmed and surveyed in the Southern Ocean. A trochoid snail was recovered from low diffuse […]
The Southern Ocean and Antarctic region currently best represent one of the few places left on our planet with conditions similar to the preindustrial age. Currently, climate models have low […]
Five main British Antarctic Survey stations were occupied throughout the year. These were Faraday and Halley (the two geophysical observatories), Signy (the main biological station), Grytviken (a multi-disciplinary sub-Antarctic station) […]
During recent years there has been a steady increase in the total world fish catch (including shellfish) to a plateau, reached in the early 1970’s, of around 70 million tonnes. […]
This chapter contains sections titled: Introduction Advantages of the Antarctic Region for Aeronomic Research High-latitude Phenomena shown by Ionograms The F2 Region Over antarctica Future of Ionospheric Research in Antarctica
An empirical model of the variation of electron concentration with height is described which overcomes some limitations found in practice with a previous widely used model (Bradley and Dudeney, 1973). […]
