4. Life cycles of Calanoides acutus, Calanus simillimus and Rhincalanus gigas (Copepoda: Calanoida) within the Scotia Sea

   The life cycles and distribution of three dominant copepods,Calanoides acutus, Calanus simillimus andRhincalanus gigas were studied from the “Discovery” collections in the Scotia Sea earlier this century.C. simillimus is a […]

5. The rapid fading of radio waves reflected from sporadic-E ionization

   A digital ionosonde has been used at Halley (75°31′S, 26°59′W) to examine the fading on time scales of a few seconds of 4.5 MHz signals reflected from sporadic-E ionization. Fourier […]

6. lonosonde signatures of Pc1 pulsations

   The first observations of the signatures of Pc1 pulsations in ionosonde echo data are reported. Oscillations are frequently observed in Doppler velocity, echo amplitude, group range and skymap echo-location position, […]

8. The effects of electric field and ring current energy increases onFlayer irregularities at auroral and subauroral latitudes

   A model of the dynamics of magnetic storms is proposed which describes the effects of magnetospheric activity on irregularities at F layer heights for auroral and subauroral latitudes. For high […]

9. Acanthocephalan infection of inshore fish in two fjords at South Georgia

   An examination of 111 fish of eight species, including 92 immature Notothenia rossii Richardson revealed nine acanthocephalan species, including four Echinorhynchida occurring in the alimentary tract and five Polymorphida in […]

10. Digenean Trematoda infection of inshore fish at South Georgia

    A sample of 111 fish of eight species caught in two fjords at South Georgia were examined for digenean trematode parasites. The alimentary tracts of all specimens were infected with […]

11. An assessment of the L shell fitting beam-swinging technique for measuring ionosphericEregion irregularity drift patterns

    The majority of current ground‐based radar experiments measuring ionospheric convection flows derive the ionospheric flow vectors from line‐of‐sight (l‐o‐s) velocity measurements made from a single radar site. In order to […]
