1 January, 1983
The Voyager 1 and 2 flybys of Saturn revealed the presence of a variety of plasma waves associated with Saturn's magnetosphere1,2, some electrostatic in nature, others apparently electromagnetic. Possibly the…Characteristics of VLF emissions manifested by their cross-spectral phase information
1 January, 1983
Natural VLF emissions received by a single antenna can be characterised at each point in the emissions' frequency-time domain by a power and a phase. Emissions received at a single…Read more on Characteristics of VLF emissions manifested by their cross-spectral phase information
In situ measurements of transionospheric VLF wave injection
1 January, 1983
VLF waves at 3.85 kHz from the Siple, Antarctica, transmitter were continuously measured by electric and magnetic receivers on a sounding rocket as the waves propagated through the neutral atmosphere…Read more on In situ measurements of transionospheric VLF wave injection
Sediment dispersal patterns in part of a deformed Mesozoic back-arc basin on South Georgia, South Atlantic
1 January, 1983
The Cumberland Bay Formation is a deformed Late Jurassic-Early Cretaceous volcaniclastic turbidite formation several kilometers thick. It has been interpreted as the fill of a back-arc basin which was active…Activity budgets of southern elephant seals, Mirounga leonina, during the breeding season
1 January, 1983
Elephant seals, Mirounga leonina, of both sexes undergo a prolonged fast during the breeding season when they rely on their reserves of blubber for energy. Activity patterns were observed in…Some aspects of feeding in the Antarctic krill, Euphausia superba
1 January, 1983 by Andrew Clarke, Peter Ward
The interaction between feeding activity, swarming behaviour and vertical migration in Antarctic krill, Euphausia superba Dana, was examined by a combination of laboratory physiology studies and intensive field sampling of…Read more on Some aspects of feeding in the Antarctic krill, Euphausia superba
K-Ar geochronology of the South Shetland Islands, Lesser Antarctica: apparent lateral migration of Jurassic to Quaternary island arc volcanism
1 January, 1983
Approximately 70 K-Ar whole-rock ages for low-K tholeiitic and andesitic volcanic and intrusive rocks from the South Shetland Islands, Antarctica, including about 50 not previously published, are reviewed. Activity mainly…Unique spawning behaviour by the Antarctic limpet Nacella (Patinigera) concinna (Strebel, 1908)
1 January, 1983
The Antarctic limpet Nacella (Patingera) concinna (Strebel, 1908) forms temporary “stacks” before spawning, a behaviour which ensures that gametes are released in close proximity. This promotes the fertilization of a…Recent temperature changes in the Arctic and Antarctic
1 January, 1983
The possibility of a global warming induced by increasing levels of atmospheric carbon dioxide has led to increased interest in monitoring global temperatures. Polar regions are of particular interest because…Read more on Recent temperature changes in the Arctic and Antarctic
Regime of the Filchner–Ronne ice shelves, Antarctica
1 January, 1983
Seismic, radio-echo, TWERLE balloon and oceanographic data of the Filchner-Ronne ice shelves are analysed. A large thin area in the central Ronne Ice Shelf is found to differ from the…Read more on Regime of the Filchner–Ronne ice shelves, Antarctica
Studies of sporadic E (Es) associated with the main ionospheric trough
1 January, 1983
The occurrence of sporadic E (ES) under the main F region trough has been established using ionograms from a vertical incidence ionosonde at Halley Bay, Antarctica (76°S, 27°W; L =…Read more on Studies of sporadic E (Es) associated with the main ionospheric trough
