Using expressions for ice-shelf creep derived by Weertman (1957) and Thomas (1973[b]) a general method is developed for calculating equilibrium thickness profiles, velocities, and strain-rates for any ice shelf. This […]
Samples from 15 Antarctic and Subantarctic localities were measured and subjected to discriminatory analysis of shell morphology. Only two species were recognized as belonging to the genus Yoldia Möller, 1842: […]
Two species of moss growing in Moss Lake on Signy Island, South Orkney Islands, had unusual morphologies with large leaves and long internodes. Both Calliergon sarmentosum and Drepanocladus cf. aduncus […]
Large numbers of the Southern Hemisphere lamprey, Geotria australis, have been found in the regurgitated food of albatrosses breeding on South Georgia. This finding suggests that this lamprey is found […]
THE presence of both paraffinic and polycyclic aromatic hydrocarbons (PAH) in sediments and soils from the Northern Hemisphere has been well documented1–5. Paraffinic hydrocarbons are generally assumed to be derived […]
The annual rate of sediment accumulation and the proportion due to resuspension in a sheltered sub-Antarctic bay has been deduced from sediment trap experiments and vertical profiles of organic matter […]
