Antarctic phytoplankton community composition and size structure: importance of ice type and temperature as regulatory factors
Read more of: Antarctic phytoplankton community composition and size structure: importance of ice type and temperature as regulatory factorsClimate change at the Western Antarctic Peninsula (WAP) is predicted to cause major changes in phytoplankton community composition, however, detailed seasonal field data remain limited and it is largely unknown […]

Deposition, recycling and archival of nitrate stable isotopes between the air-snow interface: comparison between Dronning Maud Land and Dome C, Antarctica
Read more of: Deposition, recycling and archival of nitrate stable isotopes between the air-snow interface: comparison between Dronning Maud Land and Dome C, AntarcticaThe nitrogen stable isotopic composition in nitrate (δ15N-NO−3) measured in ice cores from low-snow-accumulation regions in East Antarctica has the potential to provide constraints on past ultraviolet (UV) radiation and […]

Survey reduction for glacier movement studies
Read more of: Survey reduction for glacier movement studiesSurveys of glaciers require special reduction techniques because of the continuous movement of ice. In the past, a minimum of two surveys of a network was needed to determine glacier […]

ELF radio signals in the auroral ionosphere generated by non-linear demodulation of LF and/or MF transmissions
Read more of: ELF radio signals in the auroral ionosphere generated by non-linear demodulation of LF and/or MF transmissionsWe have conducted experiments measuring ELF and VLF radio signals in the afternoon to early morning (local time) between 24 March and 4 April 1979 in Northern Scandinavia. Apart from […]

Systematic errors in VLF direction-finding of whistler ducts—II
Read more of: Systematic errors in VLF direction-finding of whistler ducts—IIIn the previous paper (Strangeways, 1980) it was shown that the systematic error in the azimuthal bearing due to multipath propagation and incident wave polarisation (when this also constitutes an […]
