Electrical conductivity measurements from the GISP2 and GRIP Greenlandice cores
Read more of: Electrical conductivity measurements from the GISP2 and GRIP Greenlandice coresTHE direct-current electrical conductivity of glacial ice depends on its acidity1–3, and can also indicate changes in climate, as ice formed in cold, dusty periods has a high concentration of […]

The local deposition of heavy metal emissions from point sources in Antarctica
Read more of: The local deposition of heavy metal emissions from point sources in AntarcticaSurface snow samples have been analysed for the heavy metals Cd, Cu, Pb and Zn to investigate the spatial scale of local sources of pollution in Antarctica. Samples from around […]

Extreme adaptive life-cycle in a high arctic aphid, Acyrthosiphon svalbardicum
Read more of: Extreme adaptive life-cycle in a high arctic aphid, Acyrthosiphon svalbardicum1 The year-round biology of a high arctic aphid is described for the first time. 2 The life-cycle is shown to be genetically determined, and thus markedly different to temperate […]

The changing face of late Precambrian and early Palaeozoic reconstructions
Read more of: The changing face of late Precambrian and early Palaeozoic reconstructionsThe SWEAT hypothesis, linking the Southwest US and East Antarctica as conjugate rift margins of a Neoproterozoic continent has lead to major revisions of late Precambrian and early Cambrian reconstructions. […]
