The structural basement of Alexander Island consists of a wide belt of accretionary complex rocks, the LeMay Group (Bum 1984). This is overlain by ?Cretaceous-Tertiary calcalkalinevolcanic rocks (Bum 1981), and […]
Microbial activity in a marine sediment in Factory Cove, Signy Island (60°43′S, 45°38′W), South Orkney Islands in the maritime Antarctic was examined during December 1987 and January 1988. The sediment […]
This paper is a review of the literature on turbulent transfer processes over snow and ice surfaces. Current techniques for modelling these transfers for hydrological purposes are discussed.
New interferometric observations of the Wolf-Rayet star AS431 using the MERLIN network are presented. These observations had a sensitivity sufficient to map the stellar-thermal continuum radio emission with a beam […]
A 133 m deep Antarctic ice core from Dolleman Island, Antarctic Peninsula, has been profiled by dielectric measurements in the AF‐LF (20 Hz ‐ 100 kHz) frequency range. This has […]
A general method for testing the stability of a stratified, parallel shear flow is presented. The technique allows the routine determination of unstable modes from any high resolution radiosonde data […]
A mid-Palaeozoic basement to the Antarctic Peninsula is confirmed by a geochronological study of the gneissose country rock of the Mesozoic magmatic arc of eastern Graham Land. Rb–Sr whole-rock ages […]
The southern elephant seal is among the most sexually dimorphic and polygynous of all mammals: males may be more than 10 times the weight of reproducing females and only the […]
As part of the Winter Weddell Sea Project 1986 (WWSP 86), a buoy, transmitting via TIROS-N satellites to Service Argos, was inserted into an ice floe in the southern Weddell […]
Introduced mammals have had a major impact on the biota of islands in the Southern Ocean. Management plans for some islands include control measures for both introduced herbivores and carnivores […]
