We carried out a superposed epoch analysis, using a database of substorm chorus events observed at Halley, Antarctica, within an hour of magnetic midnight, to define a set of 123 […]
Dynamic provenance variations are deduced from sand-grain detrital modes in samples obtained from the CRP-2/2A drillcore. Below an important unconformity at 307 metres below sea floor (mbsf), sand grains in […]
Phagocytosis was studied in vitro using coelomic fluid of the Antarctic starfish Odontaster validus at 0°C. The number of coelomocytes present was determined and the phagocytic activity of the phagocytic […]
The British Antarctic Survey (BAS) maintains a research and support station on Rothera Point (67 degrees 34’S, 68 degrees 08’W), located on the southeastern side of Adelaide Island, about 15 […]
We present an overview of exisiting problems in air-mass factor calculations for NO2 vertical column measurements by UV-visible ground-based spectrometry, Sensitivity studies made using different radiative transfer models allow us […]
Field studies and sampling of terrestrial invertebrates for ecophysiological experiments were undertaken in the summer of 1994 and 1995 in different geographic regions of the Asian Transect (Krasnoyarsk to Karaul) […]
In order to estimate past changes in atmospheric NOx concentration, nitrate, an oxidation product of NOx, has often been measured in polar ice cores. In the frame of the European […]
In January 1998 an imaging riometer system was deployed at Halley, Antarctica (76°S, 27°W), involving the construction of an array of 64 crossed-dipole antennas and a ground plane. Weather conditions […]
Magnetospheric line radiation (MLR) events are relatively narrowband VLF signals that sometimes drift in frequency and have been observed in both ground-based and satellite data sets. We present the results […]
Magnetospheric line radiation (MLR) events are relatively narrowband VLF signals (∼30 Hz) that sometimes drift in frequency and that have been observed in both ground-based and satellite data sets. We […]
