The response of large ice sheets to climatic change
Read more of: The response of large ice sheets to climatic changeThe prediction of short-term (100 year) changes in the mass balance of ice sheets and longer-term (1000 years) variations in their ice volumes is important for a range of climatic […]

Use of VLF transmissions in the location and mapping of lightning-induced ionisation enhancements (LIEs)
Read more of: Use of VLF transmissions in the location and mapping of lightning-induced ionisation enhancements (LIEs)Lightning-induced ionisation enhancements (LIEs) are usually produced by short (~ 1 s) bursts of energetic electrons precipitated from the radiation belts in the process of amplifying whistlers. During their short […]

Temperature variation and its biological significance in fellfield habitats on a maritime Antarctic island
Read more of: Temperature variation and its biological significance in fellfield habitats on a maritime Antarctic islandTemperatures within soil and plant habitats on Signy Island in the maritime Antarctic were measured during 1987. Four sites were monitored using minithermistors attached to a data logging system. Three […]

Factors causing the limitation of growth of terrestrial algae in maritime Antarctica during late summer
Read more of: Factors causing the limitation of growth of terrestrial algae in maritime Antarctica during late summerThe factors causing the cessation of growth and decline of microalgal communities on Antarctic fell-field soils during late summer were investigated. Physical and chemical amendments were applied within small enclosures […]
