1. An assessment of the L shell fitting beam-swinging technique for measuring ionosphericEregion irregularity drift patterns

   The majority of current ground‐based radar experiments measuring ionospheric convection flows derive the ionospheric flow vectors from line‐of‐sight (l‐o‐s) velocity measurements made from a single radar site. In order to […]

4. The importance of understanding annual and shorter-term temperature patterns and variation in the surface levels of polar soils for terrestrial biota

   Ground temperatures in the top few centimetres of the soil profile are key in many biological processes yet remain very poorly documented, especially in the polar regions or over longer […]

5. ‘Business as usual’: drilling predation across the K-Pg mass extinction event in Antarctica

   A survey of 759 predatory drill holes in Late Cretaceous and Paleogene molluscan and serpulid worm prey from Seymour Island (Antarctica) has allowed exploration of the effects of the K-Pg […]

6. The internal structure of the Brunt Ice Shelf from ice-penetrating radar analysis and implications for ice shelf fracture

   The rate and direction of rift propagation through ice shelves depends on both the stress field and the heterogeneity, or otherwise, of the physical properties of the ice. The Brunt […]

7. A New Daily Observational Record from Grytviken, South Georgia: Exploring Twentieth-Century Extremes in the South Atlantic

   The sparse nature of observational records across the mid- to high latitudes of the Southern Hemisphere limits the ability to place late-twentieth-century environmental changes in the context of long-term (multidecadal […]

8. Non-native microbial introductions: what risk to Antarctic ecosystems?

   Antarctica’s biodiversity and its intrinsic values are potentially at risk from the introduction of non-native species, derived from a range of sources including human activities. Whilst controls on introducing plants […]

9. The devil is in the detail: small-scale sexual segregation despite large-scale spatial overlap in the wandering albatross

   Sexual segregation in foraging habitat occurs in many marine predators and is usually attributed to competitive exclusion, different parental roles of each sex or niche specialisation associated with sexual size […]

10. Life in the intertidal: cellular responses, methylation and epigenetics

    1.Phenotypic plasticity is essential for the persistence of organisms under changing environmental conditions but the control of the relevant cellular mechanisms including which genes are involved and the regulation of […]

11. Spacecraft surface charging induced by severe environments at geosynchronous orbit

    Severe and extreme surface charging on geosynchronous spacecraft is examined through the analysis of 16 years of data from particles detectors on-board the Los Alamos National Laboratory spacecraft. Analysis shows […]

12. Arctic Sea Ice Loss in Different Regions Leads to Contrasting Northern Hemisphere Impacts

    To explore the mechanisms linking Arctic sea ice loss to changes in midlatitude surface temperatures, we conduct idealized modeling experiments using an intermediate general circulation model and with sea ice […]
