1. Twentieth century increase in snowfall in coastal West Antarctica

   The Amundsen Sea sector of the West Antarctic ice sheet has been losing mass in recent decades; however, long records of snow accumulation are needed to place the recent changes […]

2. Solar wind-atmospheric electricity-cloud microphysics connections to weather and climate

   We review recent research articles that present observations of the large-scale day-to-day dynamic tropospheric response to changes in the downward current density Jz of the global atmospheric electric circuit (GEC). […]

3. Long-term changes in population size, distribution and productivity of skuas (Stercorarius spp.) at Signy Island, South Orkney Islands

   In this study, we investigate the numbers, productivity and territory distribution of the two species of skuas (brown Stercorarius lonnbergi and south polar Stercorarius maccormicki) breeding at Signy Island, South […]

4. Rock comminution as a source of hydrogen for subglacial ecosystems

   Substantial parts of the beds of glaciers, ice sheets and ice caps are at the pressure melting point1. The resulting water harbours diverse subglacial microbial ecosystems2, 3 capable of affecting […]

5. The migration of the great snipe Gallinago media: intriguing variations on a grand theme

   The migration of the great snipe Gallinago media was previously poorly known. Three tracks in 2010 suggested a remarkable migratory behaviour including long and fast overland non-stop flights (Klaassen et […]

6. Biogeography of cephalopods in the Southern Ocean using habitat suitability prediction models

   Our understanding of how environmental change in the Southern Ocean will affect marine diversity, habitats and distribution remain limited. The habitats and distributions of Southern Ocean cephalopods are generally poorly […]

7. Usnea antarctica, an important Antarctic lichen, is vulnerable to aspects of regional environmental change

   Studies of cryptogam responses to climate change in the polar regions are scarce because these slow-growing organisms require long-term monitoring studies. Here, we analyse the response of a lichen and […]

8. Antarctic scientific collaboration. The role of the SCAR

   The early national expeditions to Antarctica were short-term, with science usually driven by the interests and opportunities of those scientists who were taken along. Some expeditions made important collections of […]

9. Observations of surface momentum exchange over the marginal-ice-zone and recommendations for its parametrisation

   Comprehensive aircraft observations are used to characterise surface roughness over the Arctic marginal ice zone (MIZ) and consequently make recommendations for the parameterization of surface momentum exchange in the MIZ. […]

10. The cephalopod prey of the Weddell seal, Leptonychotes weddellii, a biological sampler of the Antarctic marine ecosystem

    Weddell seals, Leptonychotes weddellii, are important apex predators in the food web of the Antarctic marine ecosystem. However, detailed information on their trophic relationships with cephalopods is scarce. Moreover, cephalopods […]

11. Marine colonization and biodiversity at Ascension Island and remote islands

    Little is known about colonization of remote island coasts by marine invertebrates, other than corals. The structure of hard substrata assemblages was investigated across Ascension Island’s littoral zone in comparison […]
