The Antarctic Circumpolar Current (ACC) crosses rugged topography to the north of South Georgia. In this region the subsurface expression of the Polar Front (PF) is generally thought to occur […]
In terms of the convention governing the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), management advice for the Antarctic krill (Euphausia superba) fishery should take the needs […]
Observations of field strengths of signals from a number of VLF transmitters, after propagation over long paths in the Earth–ionosphere waveguide, have been used to examine changes in the daytime […]
CRP-2/2A hole, drilled at 77.006oS and 163.719oE, about 14 km east of Cape Roberts, in the Ross Sea, reached 624 metres below sea floor and recovered a thick Miocene-Oligocene succession […]
It has been suggested that the dynamics of the magnetotail may exhibit forced and/or self-organized critical behaviour. Recent analysis of experimental data seem to be in concert with this idea. […]
Recent suggestion and experimental indications that the magnetotail dynamics exhibit self-organized critical behavior have re-motivated interest in sandpile (avalanche) models. Some examples of specific interest for geomagnetic activity have the […]
High-density SNP arrays developed for humans and their companion species provide a rapid and convenient tool for generating SNP data in closely-related non-model organisms, but have not yet been widely […]
We detected a compound previously unreported in the atmosphere, trifluoromethyl sulfur pentafluoride (SF5CF3). Measurements of its infrared absorption cross section show SF5CF3 to have a radiative forcing of 0.57 watt […]
Examination of fracture surfaces near the fusion crust of the martian meteorite Allan Hills (ALH) 84001 have been conducted using scanning electron microscopy (SEM) and atomic force microscopy (AFM) and […]
An account is given of phanerogams and cryptogams(bryophytes and lichens) growing in extreme habitats in Antarctica. These include high altitude and far southern sites, geothermal sites in volcanic areas, and […]
The ammonium, calcium, and sodium concentrations from three intermediate depth ice cores drilled in the area of Dronning Maud Land, East Antarctica, have been investigated. Since all measurements were performed […]
For the first time, annually resolved accumulation rates have been determined in central Antarctica by means of counting seasonal signals of ammonium, calcium, and sodium. All records, obtained from three […]
