Present radiative transfer methods in physically based energy budget models of snow do not include adequate spectral or directional resolution to deal with the scattering of solar radiation. This paper […]
A 181 m long ice core was drilled at 79°36′51″ S, 45°43′28″ W, near the summit of Berkner Island, Antarctica (886 m a.s.l.). Berkner Island is located between the Filchner […]
This study examined pituitary sensitivity to exogenous gonadotrophin-releasing hormone (GnRH) in relation to time of year and changes in plasma progesterone, testosterone, luteinising hormone (LH), and follicle-stimulating hormone (FSH) concentrations […]
The calcium (representing dust) concentration record of the last 100,000 years from the Greenland Ice Core Project (GRIP) ice core shows a huge dynamic range (factor>100). The relationship between dust […]
We study an aspect of substorm occurrence during Earth passage of the October 1995 magnetic cloud and the corotating stream overtaking it. The substorms were identified primarily by five latitudinal […]
On 7 December 1992, a moderate substorm was observed by a variety of satellites and ground-based instruments. Ionospheric flows were monitored near dusk by the Goose Bay HF radar and […]
The sea-surface distribution of four selected fossilizable phytoplankton groups (coccolithophores, diatoms, silicoflagellates and dinoflagellates) has been studied along a transect from Cape Town (34°S) to South Sandwich Islands (57°S) during […]
1. Bottom trawl surveys on the South Georgia shelf indicate episodic declines in the abundance of the mackerel icefish Champsocephalus gunnari that, since 1990, are not directly attributable to commercial fishing. […]
A large sample of otoliths from the mackerel icefish (Champsocephalus gunnari) was measured and weighed and their effectiveness as predictors of fish length and fish mass determined. The two measures, […]
The essential aim of biological sampling is to obtain samples that are representative of the targets under consideration. Sampling in support of in situ target strength studies should be aimed […]
Analyses of size at sexual maturity were undertaken on samples of Patagonian toothfish (Dissostichus eleginoides) caught in the commercial fishery within Subarea 48.3. The results for 1996 indicate that Lm50 […]
1. Recently, a small predatory beetle, Trechisibus antarcticus (Carabidae), was accidentally introduced onto the island of South Georgia, sub-Antarctic. 2. From the presumed site of introduction the beetle is invading […]
