Mie 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 […]
Results 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 […]
Data 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 […]
During the austral midsummers of 1989/1990 and 1990/1991, seven grazing experiments were undertaken near South Georgia. The copepods spanned 3 orders of magnitude in body mass, from young copepodids of […]
During seven days of operations involving the setting and hauling of longlines to catch the toothfish Dissostichus eleginoides around the South Sandwich Islands, actual and potential interactions with seabirds were […]
Southern elephant seals Mirounga leonina display extreme sexual dimorphism. In addition females show great variation in size and stored resources at parturition. Therefore they present an excellent opportunity for examination […]
A method for extending the calibrated temperature rang of a solid-state capacitive humidity sensor is presented. This technique is applicable to relative humidity instruments that are based around solid-state sensors.
Continuous electrical records covering a climatic cycle are presented for the Greenland Ice Core Project deep ice core from Greenland. Electrical conductivity measurement (ECM) measures the acid content of the […]
Nitrate is one of the major impurities in polar snow, and is relatively easy to analyse. Large amounts of data therefore exist, including some from cores extending into the last […]
The occurrence of PMSEs with time of day shows a semi-diurnal variation with minima at 8 and 20 h LT. PMSE layers observed for more than 30 min show an […]
The Antarctic Peninsula magmatic arc was the site of Andean-type subduction from at least Silurian times to the late Cenozoic. Hydrothermal galenas from eight localities in accretionary complex, arc volcanic […]
