Simultaneous conjugate observations of dynamic variations in high-latitude dayside convection due to changes in IMFBy
Read more of: Simultaneous conjugate observations of dynamic variations in high-latitude dayside convection due to changes in IMFByTwo conjugate HF radars are currently operating at Goose Bay, Labrador, and Halley Station, Antarctica, and are providing continuous, high temporal resolution measurements of plasma convection over large areas of […]

Interpretation of reconnaissance gravity and aeromagnetic surveys of the Antarctic Peninsula
Read more of: Interpretation of reconnaissance gravity and aeromagnetic surveys of the Antarctic PeninsulaTwo‐dimensional models are presented for the crustal structure of the Antarctic Peninsula, a Mesozoic‐Cenozoic magmatic arc on the southeast Pacific margin. The models are constrained by measured rock properties. The […]

Modelling the response of the thermosphere and ionosphere to geomagnetic storms: Effects of a mid-latitude heat source
Read more of: Modelling the response of the thermosphere and ionosphere to geomagnetic storms: Effects of a mid-latitude heat sourceThe 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 […]

Target strengths of Antarctic krill (Euphausia superba) at 38 and 120 kHz
Read more of: Target strengths of Antarctic krill (Euphausia superba) at 38 and 120 kHzEncaged 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 […]

Annual variation in the timing of reproduction in Antarctic fur seals,Arctocephalus gazella, at Bird Island, South Georgia
Read more of: Annual variation in the timing of reproduction in Antarctic fur seals,Arctocephalus gazella, at Bird Island, South GeorgiaThe 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 […]
