Association of substorm chorus events with drift echoes
Over recent years, substorm chorus events (SCEs) have been proposed as a useful indicator of substorm onset. The events are regularly seen in the data from the VELOX (VLF/ELF Logger […]

Statistical characteristics of the spatial distribution of Pc3-4 geomagnetic pulsations at high latitudes in the Antarctic regions
Read more of: Statistical characteristics of the spatial distribution of Pc3-4 geomagnetic pulsations at high latitudes in the Antarctic regionsThe diumal variations in the parameters of Pc3 (20–60 mHz) and Pc4 (10–19 mHz) pulsations at latitudes of the dayside cusp and polar cap have been studied using data of […]

An introduction to EASIZ (Ecology of the Antarctic Sea Ice Zone): an integrated programme of water column, benthos and bentho-pelagic coupling in the coastal environment of Antarctica
Read more of: An introduction to EASIZ (Ecology of the Antarctic Sea Ice Zone): an integrated programme of water column, benthos and bentho-pelagic coupling in the coastal environment of AntarcticaThe EASIZ (Ecology of the Antarctic Sea Ice Zone) programme ran from 1994 to 2004, and involved over 150 scientists from more than 17 countries. The main scientific aim was […]

Climate, energy and diversity
Read more of: Climate, energy and diversityIn recent years, a number of species–energy hypotheses have been developed to explain global patterns in plant and animal diversity. These hypotheses frequently fail to distinguish between fundamentally different forms […]

The importance of atmospheric precipitation in storm-time relativistic electron flux drop outs
Read more of: The importance of atmospheric precipitation in storm-time relativistic electron flux drop outsDuring the sudden decrease of geosynchronous electron flux (>2 MeV) of 17:10–17:20 UT, January 21, 2005 large-scale precipitation into the atmosphere was observed. Estimates from ground-based radio propagation experiments at […]

Modeling polar ionospheric effects during the October-November 2003 solar proton events
Read more of: Modeling polar ionospheric effects during the October-November 2003 solar proton eventsAt Ny Ålesund, Svalbard (78°54′N, 11°53′E, L ∼ 18), a narrowband VLF receiver was used to monitor the behavior of the amplitude of several high-power transmitters located in the Northern […]

Hypolithic colonization of opaque rocks in the Arctic and Antarctic polar desert
Read more of: Hypolithic colonization of opaque rocks in the Arctic and Antarctic polar desertThe colonization of the underside of rocks normally requires that the material is sufficiently translucent to allow the penetration of photosynthetically active radiation. We examined the underside of 950 opaque […]

Responses of terrestrial Antarctic ecosystems to climate change
Read more of: Responses of terrestrial Antarctic ecosystems to climate changeAntarctic terrestrial biota are generally limited by the inexorably linked environmental factors of low summer temperature and lack of available water. However, in parts of the Antarctic, both these factors […]

Morphological differences in Lissarca notorcadensis Melvill and Standen, 1907 from the Scotia, Weddell and Ross Seas
Read more of: Morphological differences in Lissarca notorcadensis Melvill and Standen, 1907 from the Scotia, Weddell and Ross SeasThe isolated Southern Ocean has given rise to specially adapted, endemic species. The uniformity of physical conditions within the Southern Ocean south of the Polar Front is thought to limit […]

ULF Doppler oscillation of L = 2.5 flux tubes
Read more of: ULF Doppler oscillation of L = 2.5 flux tubesPlasmaspheric ducts may execute Doppler oscillations driven by propagating ultra-low frequency (ULF) waves. We examined about 100 such events recorded over 1 year under magnetically quiet conditions at L = […]
