2. The atmospheric HCHO budget at Dumont d’Urville (East Antarctica): Contribution of photochemical gas-phase production versus snow emissions

   HCHO was monitored throughout the year 2009 at the coastal East Antarctic site of Dumont d’Urville (DDU) using Aerolaser AL-4021 analyzers. The accurate determination of less than 100 pptv required […]

3. Experimental influence of pH on the early life-stages of sea urchins II: increasing parental exposure times gives rise to different responses

   Many studies into the responses of early life-stages to ocean acidification utilise offspring obtained from parents reared under present-day conditions. Their offspring are directly introduced to altered-pH conditions. This study […]

4. Characterisation of vertical BrO distribution during events of enhanced tropospheric BrO in Antarctica, from combined remote and in-situ measurements

   Tropospheric BrO was measured by a ground-based remote-sensing spectrometer at Halley in Antarctica in spring 2007, and BrO was measured by satellite-borne remote-sensing spectrometers using similar spectral regions and similar […]

5. The structure and effect of suture zones in the Larsen C Ice Shelf, Antarctica

   Ice-shelf fractures frequently terminate where they encounter suture zones, regions of material heterogeneity that form between meteoric inflows in ice shelves. This heterogeneity can consist of marine ice, meteoric ice […]

6. Isochronous information in a Greenland ice sheet radio-echo sounding dataset

   The evaluation of ice sheet models is one of the pressing problems in the study of ice sheets dynamics. Here we examine the question of how much isochronous information is […]

7. Annotated zoogeography of non-marine Tardigrada. Part I: Central America

   Dividing the world into nine regions, this first paper describes literature records of the limno-terrestrial tardigrades (Tardigrada) reported from Central America. Updating previously published species lists we have revised the […]

9. The effects of experimental temperature elevation on populations of cryptostigmatic mites in high Arctic soils

   Soil warming experiments were conducted in tundra heath and polar semi-desert soils at the High Arctic location of Ny-Alesund, West Spitsbergen, Svalbard, The warming treatment resulted in an 8-10% increase […]

10. A 25-year record of 10 kHz sferics noise in Antarctica: Implications for tropical lightning levels

    We report measured levels of very low frequency (VLF) radio noise at ∼10 kHz, due to lightning sferics, observed at Halley Station, Antarctica (76°S, 27°W) between 1971 and 1996. The […]

11. Layers of Antarctic krill, Euphausia superba  : are they just long krill swarms?

    Antarctic krill, Euphausia superba Dana, a major component in the southern ocean food web, typically occur in aggregations that range from small, discrete swarms and schools through to layers and […]

12. Localized activation of the distant tail neutral line just prior to substorm onsets

    We have found flow burst features in the nightside ionosphere that are thought to be the ionospheric signature of distant tail reconnection. These are observed to form just prior to […]
