3. Modelling the response of the thermosphere and ionosphere to geomagnetic storms: Effects of a mid-latitude heat source

   The UCL-Sheffield coupled thermosphere/ionosphere model has been used to assess the consequences of a heat source from ring current ion precipitation during a geomagnetic storm. Such a source might in […]

4. Target strengths of Antarctic krill (Euphausia superba) at 38 and 120 kHz

   Encaged aggregations of live krill in good to pristine condition have been ensonified at 38 and 120 kHz. Concurrent underwater television observations of behavior resemble those made by underwater divers […]

9. Annual variation in the timing of reproduction in Antarctic fur seals,Arctocephalus gazella, at Bird Island, South Georgia

   The arrival of Antarctic fur seals at a breeding beach on Bird Island, South Georgia, was studied over five consecutive breeding seasons, 1983 to 1987. Experienced bulls arrived first and […]

10. Seasonal and temporal variations of field-aligned currents and ground magnetic deflections during substorms

    Field‐aligned currents (FACs), also known as Birkeland currents, are the agents by which energy and momentum are transferred to the ionosphere from the magnetosphere and solar wind. This coupling is […]

11. Statistical properties of plasmaspheric hiss from Van Allen Probes observations

    Van Allen Probes observations are used to statistically investigate plasmaspheric hiss wave properties. This analysis shows that the wave normal direction of plasmaspheric hiss is predominantly field aligned at larger […]

12. Geographic variation in the foraging behaviour of South American fur seals

    The implicit assumption of many ecological studies is that animal behaviour and resource use are geographically uniform. However, central place foraging species often have geographically isolated breeding colonies that are […]
