3. An improved model of the variation of electron concentration with height in the ionosphere

   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). […]

4. Climatic change and geomagnetic field reversals: A statistical correlation

   Dates of climatic episodes recorded in deep-sea cores are compared with the dates of palaeomagnetic polarity transitions during the Upper Pliocene period. The chance that the number of observed coincident […]

5. Dissipation of tidal energy by Antarctic ice shelves

   FLEXING of ice shelves may dissipate enough tidal energy to have a significant effect on the Moon’s retreat from the Earth. It is generally agreed that tidal friction slows the […]

7. Theoretical models for interpreting the dielectric behaviour of HF-doped ice

   To understand the recent dielectric measurements made on HF-doped ice single crystals requires a full knowledge of the concentration of electrical defects present in ice and their subsequent interactions. Previous […]

8. The effect of induced currents in the sea on magnetic bays observed at a coastal observatory

   It is widely accepted that return currents from the auroral electrojet are responsible for the magnetic bays in the D component. The different directions of the return currents, at either […]

9. Man’s impact on seals

   The major direct effects of man on seal populations are caused by hunting. Subsistence hunting using traditional methods has a long history and generally resulted in a balance between the […]

11. Metabolic adaptations of antarctic terrestrial micro-arthropods

    1. 1. Comparative analyses of standard metabolism, as measured by weight specific oxygen consumption, for Antarctic and temperate terrestrial Acari show that polar forms of the Cryptostigmata and Mesostigmata exhibit […]

12. Oxygen Uptake by Cryptopygus antarcticus (Collembola) at South Georgia

    Determinations of oxygen uptake of size classes I, II, III and IV of the collembolan Cryptopygus antarcticus Willem at +5°, +10° and +20°C were made at South Georgia, sub-Antarctic. The […]
