1. Simultaneous observation of chorus and hiss near the plasmapause

   On 4 August 2010 a moderate geomagnetic storm occurred with minimum Dst of −65 nT and maximum Kp of 7−. Shortly after the onset of this storm, VLF chorus was […]

2. Variable temperature effects of Open Top Chambers at polar and alpine sites explained by irradiance and snow depth

   Environmental manipulation studies are integral to determining biological consequences of climate warming. Open Top Chambers (OTCs) have been widely used to assess summer warming effects on terrestrial biota, with their […]

3. Comparison of the structure and function of Southern Ocean regional ecosystems: The Antarctic Peninsula and South Georgia

   The ocean ecosystems around the west Antarctic Peninsula and South Georgia are two of the best described regional ecosystems of the Southern Ocean. They therefore provide a useful basis for […]

4. On the statistical significance of surface air temperature trends in the Eurasian Arctic region

   This study investigates the statistical significance of the trends of station temperature time series from the European Climate Assessment & Data archive poleward of 60°N. The trends are identified by […]

5. Early Cenozoic differentiation of polar marine faunas

   The widespread assumption that the origin of polar marine faunas is linked to the onset of major global cooling in the Late Eocene – Early Oligocene is being increasingly challenged. […]

6. Bacterial biodiversity in deep-sea sediments from two regions of contrasting surface water productivity near the Crozet Islands, Southern Ocean

   The relationship between surface-derived particulate organic matter (POM) and deep-sea sediment bacterial abundance, community structure and composition was investigated in two different sediment layers from two zones of contrasting surface […]

7. Metagenomic analysis of a a southern maritime Antarctic soil

   Our current understanding of Antarctic soils is derived from direct culture on selective media, biodiversity studies based on clone library construction and analysis, quantitative PCR amplification of specific gene sequences […]

8. Scotia Arc Acari: antiquity and origin

   The Scotia Arc comprises South Georgia, South Sandwich, South Orkney and South Shetland Islands together with the Antarctic Peninsula. Free-living Acari of the Scotia Arc contain immigrant and endemic elements. […]

9. Sedimentation on the continental rise west of the Antarctic Peninsula over the last three glacial cycles

   The continental rise west of the Antarctic Peninsula includes a number of large sediment mounds interpreted as contourite drifts. Cores from six sediment drifts spanning some 650 km of the […]

10. Evidence for Gondwanan origins for Sassafras (Lauraceae)? Late Cretaceous fossil wood of Antarctica

    Sassafrasoxylon gottwaldii sp. nov. is a new taxon for fossil wood with a suite of features diagnostic of Sassafras Nees & Eberm. of the Lauraceae. The fossil wood described is […]

11. Illicioxylon, an element of Gondwanan polar forests? Late Cretaceous and early Tertiary woods of Antarctica

    The Late Cretaceous and early Tertiary sediments from the northern Peninsula region of Antarctica yield a rich assemblage of fossil wood with well preserved anatomy. Wood specimens of a previously […]
