1. A complete arc-trench system recognized in Gondwana sequences of the Antarctic Peninsula region

   Prior to Late Triassic–Early Jurassic times, the geological history of the Antarctic Peninsula region was dominated almost entirely by Gondwana sequences that together comprised a major arc-trench system. Subduction complex, […]

3. ELF radio signals produced in the auroral ionosphere by non-linear demodulation of signals from high-power amplitude-modulated transmitters

   ELF and VLF radio signals were recorded in the afternoon to early morning (local time) between 24 March and 4 April 1979, in Northern Scandinavia. Apart from signals of natural […]

5. The nocturnal intermediate layer over South Georgia

   Detailed analyses of ionograms from South Georgia (54°S, 37°W; L = 1.9) show that a nocturnal intermediate layer is frequently seen between the E- and F-regions in the height range […]

6. The importance of the maximum plasma frequency of the ionosphere in controlling the occurrence of blackout

   For locations normally equatorward of the auroral oval, it is established that there is a strong inverse association between the variations in the maximum plasma frequency of the ionosphere and […]
