Chemical alteration of rock in the Antarctic is considered to be less dominant than physical weathering processes. The research presented in this discussion represents investigations to determine the extent of […]
Aerobiological studies were conducted for >1 year using arrays of rotorod samplers at three sites on Signy Island, South Orkney Islands, maritime Antarctic. Spores of five bryophyte taxa were identified, […]
The dispersal of algae and cyanobacteria at three Antarctic fellfield sites was investigated using microscopic and culture analysis of samples from active and passive air samplers Intersite variation in the […]
Airborne fungal spores were monitored over periods of up to 131/2 months at three sites on Signy Island in the maritime Antarctic. Fungal spore concentrations in the air were much […]
In order to operate successfully and reliably in inhospitable polar climates, an aerobiological sampler requires a number of characteristics. It must sample a large volume of air, sample extremes of […]
The effectiveness of ERS 1 scatterometer data as a tool for studying the wind fields of Antarctic mesocyclones is analyzed by using 1 year’s observations of these systems derived from […]
Fore-arc magmatic sequences associated with high Mg number andesite lavas unconformably overlie LeMay Group accretionary complex in Alexander Island. High-resolution 40Ar/39Ar, U–Pb zircon, fission track and K–Ar ages demonstrate that […]
Wind fields derived from ERS-1 scatterometer data, acquired over the open water present in the western Ross Sea during the summer season, are used to study the patterns of mesoscale […]
Late Cretaceous–early Tertiary subduction-related fore-arc volcanic rocks are exposed in a north–south linear belt along the length of Alexander Island. The age and tectonic setting of these rocks is well […]
Cold-resistance studies of marine invertebrates have concentrated on intertidal sedentary organisms, which are often subjected to subzero air temperatures in winter. Mobile rock pool inhabitants have been rarely studied because […]
