3. Microbial colonization processes in Antarctic fellfield soil – an experimental overview

   The process of colonization of Antarctic fellfield soils by micro- organisms has two phases: Firstly, the immigration, survival and establishment of microbial propagules thenlselves, and secondly the stabilization of the […]

6. A comparison of plasma densities by EISCAT and the Dynasonde from auroral altitudes: evidence of intense structure

   Under conditions of moderately-energetic particle precipitation typical of the equatorward side of the auroral oval, plasma densities obtained from routine analysis of EISCAT Common Program data are often a factor […]

7. Ionogram inversion for a tilted ionosphere

   Digital ionosondes such as the Dynasonde disclose that the ionosphere is seldom horizontal even when it is plane stratified to a good approximation. The local magnetic dip does not then […]

9. Signals of atmospheric pollution in polar snow and ice

   In their upper layers, the polar ice sheets contain a detailed record of changes in the atmosphere over the industrial period. Measurements from air bubbles in ice have shown that […]

11. Factors affecting variation in foraging and activity patterns of gentoo penguins (Pygoscelis papua) during the breeding season at Bird Island, South Georgia

    (1) Radio-telemetry was used to study the activity patterns of gentoo penguins, Pygoscelis papua, at Bird Island, South Georgia, throughout the breeding season, to assess variation in foraging effort (foraging […]
