Terrestrial ecosystems: Antarctica
Read more of: Terrestrial ecosystems: AntarcticaScientific reasons for the study of terrestrial ecosystems in the Antarctic are outlined together with brief descriptions of the maritime and continental zones. Opportunities for ecological research are highlighted in […]

The use of heart rate to estimate oxygen consumption of free-ranging black-browed albatrosses Diomedea melanophrys
Read more of: The use of heart rate to estimate oxygen consumption of free-ranging black-browed albatrosses Diomedea melanophrysHeart rates (fh) and rates of oxygen consumption (V(dot)O2) were measured in eight black-browed albatrosses (Diomedea melanophrys) when walking on a treadmill, with the aim of using fh to predict […]

Two new species ofHalacarellus(Halacaridae: Acari) from South Georgia
Read more of: Two new species ofHalacarellus(Halacaridae: Acari) from South GeorgiaTwo new mite species, Halacarellus porellus n.sp. and H. novellus n.sp., are described. Both species were collected from the littoral zone in a sheltered bay on the northeast coast of […]

Angular unconformity between the López de Bertodano and La Meseta formations (Campanian-Maastrichtian and Eocene), Cockburn Island, northern Antarctic Peninsula
Read more of: Angular unconformity between the López de Bertodano and La Meseta formations (Campanian-Maastrichtian and Eocene), Cockburn Island, northern Antarctic PeninsulaA thick, largely shallow marine succession of Cretaceous and Lower Tertiary strata, deposited in the James Ross Basin, is well exposed on an archipelago of islands at the northern end […]

Seasonal variation in the feeding activity of four species of Antarctic bryozoan in relation to environmental factors
Read more of: Seasonal variation in the feeding activity of four species of Antarctic bryozoan in relation to environmental factorsMany areas of the Antarctic continental shelf support rich communities of benthic suspension feeders, of which Bryozoa are frequently an important component. These communities inhabit an environment characterised by a […]

The atmospheric correction for satellite infrared radiometer data in polar regions
Read more of: The atmospheric correction for satellite infrared radiometer data in polar regionsMie scattering models suggest that the thermal infrared emissivity of snow is relatively insensitive to variations in its properties and is dependent, primarily, on viewing angle. This gives rise to […]

The effect of disturbed-time electric fields on the inner plasmasphere
Read more of: The effect of disturbed-time electric fields on the inner plasmasphereResults from a mathematical model provide a description of the mid-latitude, low L-shell ionosphere and plasmasphere. Variations in the composition and dynamics of the plasmasphere and changes in the nature […]

A case study of storm commencement and recovery plasmaspheric electric fields near L=2.5 at equinox
Read more of: A case study of storm commencement and recovery plasmaspheric electric fields near L=2.5 at equinoxData from the VLF Doppler experiment at Faraday, Antarctica (65○ S, 64○ W) are used to study the penetration of the high-latitude convection electric field to lower latitudes during severely […]
