We report measured levels of very low frequency (VLF) radio noise at ∼10 kHz, due to lightning sferics, observed at Halley Station, Antarctica (76°S, 27°W) between 1971 and 1996. The […]
Antarctic krill, Euphausia superba Dana, a major component in the southern ocean food web, typically occur in aggregations that range from small, discrete swarms and schools through to layers and […]
We have found flow burst features in the nightside ionosphere that are thought to be the ionospheric signature of distant tail reconnection. These are observed to form just prior to […]
New Pb, Nd, and Sr isotope data are presented for geochemically similar, ∼1.1–1.2 Ga, granitoids and tonalitic‐granitic orthogneisses from Antarctica, southern Africa, and the Falkland Islands and adjoining plateau, areas […]
Egg hatching times were determined at a range of temperatures for four species of commonly occurring Antarctic copepods. At a given temperature the eggs of Rhincalanus gigas took longest to […]
The dispersion of unducted lightning-generated whistlers observed by Voyager 1 in the warm torus around density peaks at L = 5.7 and L = 5.9 are analyzed using the HOTRAY […]
The dominant features of Jovian whistlers observed by Voyager 1 in the inner cold torus around RJ ≈ 5.3 are studied using the technique of ray tracing with an offset […]
Seasonal haul-out patterns and diet of individually marked leopard seals (Hydrurga leptonyx) were investigated at Bird Island, South Georgia during the 1983–96 winters. A total of 2956 leopard seal sightings […]
Results of an HF radar study of convection during an extended quiet solar wind interval on March 10 1997 are presented. After thirty hours during which the solar wind met […]
Records of atmospheric nitrate were obtained by year-round aerosol sampling at Neumayer and Dumont D’Urville stations, located in the Atlantic and Pacific sector of coastal Antarctica, respectively. Where possible, evaluation […]
Continuous year round records of atmospheric sea-salt concentrations have been recovered at three coastal Antarctic stations (Halley, Dumont D’Urville, and Neumayer) at temporal resolutions typically between 1 day and 2 […]
This study is based on the large, mostly unreported collections of histioteuthids that have accumulated since the family was first revised by Voss in 1969. Of primary importance are the […]
