2. Dawn-dusk (y) component of the interplanetary magnetic field and the local time of the harang discontinuity

   We describe a simple method for determining the time at which the meridian of a sub-auroral magnetic observatory crosses that of the Harang discontinuity—the separation of the eastward and westward […]

5. Spread-F ionospheric irregularities and their relationship to stable auroral red arcs at magnetic mid-latitudes

   The signature of the stable auroral red arc (SAR arc) as it appears on ionograms is described. The key features are a very significant increase in the amount of spread-F […]

6. Estimation by use of field weighings of metabolic rate and food conversion efficiency in albatross chicks

   A knowledge of the assimilation of food and of the energetic demands of chicks at different stages in the growth period can provide a basis for understanding growth strategies of […]

8. Automated measurement of meal sizes and feeding frequency in albatrosses

   An artificial nest incorporating an automated weighing device, suitable for chick growth studies on some species of seabirds, is described. (2) The operating weight range is 1-7 kg, with an […]

9. Activity budgets of foraging gray-headed albatrosses

   Activity recorders were attached to 13 Gray-headed Albatrosses (Diomedea chrysostoma) rearing chicks at South Georgia in February 1982. During foraging trips to sea totalling 284 bird-days, an average of 74% […]

10. Accelerating flow of the Brunt Ice Shelf, Antarctica

    Position fixes made at the British Antarctic Survey station, Halley, on the Brunt Ice Shelf are considered for the period 1968–82. These show an initial westward velocity of approximately 400 […]

11. Electrical resistivity of ice from the Antarctic Peninsula, Antarctica

    Georesistivity soundings have been carried out at four sites in the Antarctic Peninsula. The objective of the work was to investigate the electrical behaviour of ice from an area where […]

12. Glaciological and oceanographic calculations of the mass balance and oxygen isotope ratio of a melting ice shelf

    Glaciological estimates of the ice supply to George VI Ice Shelf are obtained by integrating the accumulation over the catchment. The basal melt (or possible shelf thickening) rates for the […]
