1. The theory of radio windows in planetary magnetospheres

   The theory of radio windows given in two previous papers for a stratified cold plasma is extended to apply in a warm plasma. It is used to investigate one suggested […]

2. Theory of wave polarization of radio waves in magnetospheric cavities

   When interpreting observations of radio waves of low frequency in magnetospheric cavities, it is often assumed that the electron concentra­tion is small enough for the ray paths to be treated […]

4. Zooplankton-mediated carbon flux in the Southern Ocean: influence of community structure, metabolism and behaviour

   The biological carbon pump (BCP) exerts an important control on climate, exporting organic carbon from the ocean surface to interior. Zooplankton are a key component of the BCP and may […]

5. Metapopulation dynamics of roseate terns: Sources, sinks and implications for conservation management decisions

   Habitat management to restore or create breeding sites may allow metapopulations to increase in size and reduce the risk of demographic stochasticity or disasters causing metapopulation extinction. However, if newly […]

6. Factors influencing the habitat use of sympatric albatrosses from Macquarie Island, Australia

   Differences in habitat use of sympatric species are influenced by variability in functional morphology and life history trade-offs and are expected to shape species resilience to environmental change. To determine […]

7. The effects of enhanced sea ice export from the Ross Sea on recent cooling and freshening of the Southeast Pacific

   The top 2000 m of the Southern Ocean has freshened and warmed over recent decades. However, the high-latitude (south of 50°S) southeast Pacific was observed to be cooler and fresher […]

8. Responses of sub-ice platelet layer thickening rate and frazil-ice concentration to variations in ice-shelf water supercooling in McMurdo Sound, Antarctica

   Persistent outflow of supercooled ice-shelf water (ISW) from beneath McMurdo Ice Shelf creates a rapidly growing sub-ice platelet layer (SIPL) with a unique crystallographic structure under the sea ice in […]

9. Scaling of size, shape and surface roughness in Antarctic krill swarms

   Antarctic krill are obligate swarmers and the size and shape of the swarms they form can have a major influence on trophic interactions and biogeochemical fluxes. Parameterizing variability in size […]

10. Thurston Island (West Antarctica) between Gondwana subduction and continental separation: a multi-stage evolution revealed by apatite thermochronology

    The first low‐temperature thermochronological data from Thurston Island, West Antarctica, provide insights into the poorly constrained thermo‐tectonic evolution of the paleo‐Pacific margin of Gondwana since the Late Paleozoic. Here we […]

11. Expired drugs in the remote environment

    The British Antarctic Survey Medical Unit works in a very remote area of the world, with several Antarctic bases receiving only a single annual resupply of consumable goods. Pharmaceuticals supplied […]

12. Respiration rates and active carbon flux of mesopelagic fishes (Family Myctophidae) in the Scotia Sea, Southern Ocean

    Mesopelagic fish have recently been highlighted as an important, but poorly studied component of marine ecosystems, particularly regarding their role in the marine pelagic food webs and biogeochemical cycles. Myctophids […]
