The evaluation of ice sheet models is one of the pressing problems in the study of ice sheets dynamics. Here we examine the question of how much isochronous information is […]
Dividing the world into nine regions, this first paper describes literature records of the limno-terrestrial tardigrades (Tardigrada) reported from Central America. Updating previously published species lists we have revised the […]
Soil warming experiments were conducted in tundra heath and polar semi-desert soils at the High Arctic location of Ny-Alesund, West Spitsbergen, Svalbard, The warming treatment resulted in an 8-10% increase […]
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 […]
