Dawn-dusk (y) component of the interplanetary magnetic field and the local time of the harang discontinuity
Read more of: Dawn-dusk (y) component of the interplanetary magnetic field and the local time of the harang discontinuityWe 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 […]

Spread-F ionospheric irregularities and their relationship to stable auroral red arcs at magnetic mid-latitudes
Read more of: Spread-F ionospheric irregularities and their relationship to stable auroral red arcs at magnetic mid-latitudesThe 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 […]

Estimation by use of field weighings of metabolic rate and food conversion efficiency in albatross chicks
Read more of: Estimation by use of field weighings of metabolic rate and food conversion efficiency in albatross chicksA 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 […]

Activity budgets of foraging gray-headed albatrosses
Read more of: Activity budgets of foraging gray-headed albatrossesActivity 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% […]

Accelerating flow of the Brunt Ice Shelf, Antarctica
Read more of: Accelerating flow of the Brunt Ice Shelf, AntarcticaPosition 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 […]
