2. Geomagnetic activity and polar surface air temperature variability

   Here we use the ERA-40 and ECMWF operational surface level air temperature data sets from 1957 to 2006 to examine polar temperature variations during years with different levels of geomagnetic […]

3. Effects of simulated light regimes on gene expression in Antarctic krill (Euphausia superba Dana)

   A change in photoperiod has been implicated in triggering a transition from an active to a quiescent state in Antarctic krill. We examined this process at the molecular level, to […]

4. The role of eddies in the Southern Ocean temperature response to the Southern Annular Mode

   The role of eddies in modulating the Southern Ocean response to the southern annular mode (SAM) is examined, using an ocean model run at multiple resolutions from coarse to eddy […]

5. Growth, dynamics and deglaciation of the last British-Irish ice sheet: the deep-sea ice-rafted detritus record

   The evolution and dynamics of the last British-Irish Ice Sheet (BIIS) have hitherto largely been reconstructed from onshore and shallow marine glacial geological and geomorphological data. This reconstruction has been […]

6. A new method for high-resolution methane measurements on polar ice cores using continuous flow analysis

   Methane (CH4) is the second most important anthropogenic greenhouse gas in the atmosphere. Rapid variations of the CH4 concentration, as frequently registered, for example during the last ice age, have […]

7. Assessment of soil moisture fields from imperfect climate models with uncertain satellite observations

   We demonstrate that global satellite products can be used to evaluate climate model soil moisture predictions but conclusions should be drawn with care. The quality of a limited area climate […]

8. Quantitative relationships between benthic diatom assemblages and water chemistry in Macquarie Island lakes and their potential for reconstructing past environmental changes

   This study is the first published survey of diatom-environment relationships Oil sub-Antarctic Macquarie Island. Fifty-eight sites in 50 coastal and inland lakes were sampled for benthic diatoms and water chemistry. […]

9. Seasonal changes in basal conditions at Briksdalsbreen, Norway: the winter-spring transition

   The winter-spring transition is a dynamic time within the glacier system, because it marks a period of instability as the glacier undergoes a change in state from winter to summer. […]

10. Geolocators map the wintering grounds of threatened Lesser Kestrels in Africa

    Aim To identify the wintering grounds of the threatened western European Lesser Kestrels to focus conservation efforts in those areas. Location Huelva Province, southern Spain, as breeding range, and western […]

11. Effects of geolocator attachments on breeding parameters of Lesser Kestrels

    Light level geolocators, also known as GLS loggers, are electronic devices intended for tracking the location of wide-ranging animals using ambient light to estimate latitude and longitude. Miniaturized geolocators that […]

12. Vegetation cover regulates the quantity, quality and temporal dynamics of dissolved organic carbon and nitrogen in Antarctic soils

    Populations of the two native Antarctic vascular plant species (Deschampsia antarctica and Colobanthus quitensis) have expanded rapidly in recent decades, yet little is known about the effects of these expansions […]
