1. Interactions between humans and leopard seals

   In July 2003 Kirsty Brown, a marine biologist at Rothera Research Station (West Antarctic Peninsula), was attacked and drowned by a leopard seal (Hydrurga leptonyx). As a direct consequence, a […]

2. Observations of the wavenumber 1 and 2 components of the semi-diurnal tide over Antarctica

   This paper combines four years of radar wind data from Halley and Scott Base in an attempt to resolve the zonal structure of the semi-diurnal tide over Antarctica and to […]

3. Stable isotopes indicate sex-specific and long-term individual foraging specialisation in diving seabirds

   An important aspect of foraging ecology is the extent to which different individuals or genders within a population exploit food resources in a different manner. For diving seabirds, much of […]

4. Development and evaluation of a DNA-barcoding approach for the rapid identification of nematodes

   Free-living nematodes are abundant in all marine habitats, are highly diverse, and can be useful for monitoring anthropogenic impacts on the environment. Despite such attributes, nematodes are effectively ignored by […]

5. Aerosol deposited in East Antarctica over the last glacial cycle: detailed apportionment of continental and sea-salt contributions

   The major ions, sodium (Na+), calcium (Ca2+), and chloride (Cl−), deposited in central Antarctica and preserved in ice cores originate from both marine and continental sources. They provide important proxy […]

6. Evidence for geographic isolation and signs of endemism within a protistan morphospecies

   The possible existence of endemism among microorganisms resulting from and preserved by geographic isolation is one of the most controversial topics in microbial ecology. We isolated 31 strains of “Spumella-like” […]

7. Incursion and excursion of Antarctic biota: past, present and future

   Aim To investigate the major paradigms of intense isolation and little anthropogenic influence around Antarctica and to examine the timings and scales of the modification of the southern polar biota. […]

8. Shallow benthic communities of South Georgia Island

   Benthic communities in several fjords and sheltered bays of the north coast of South Georgia Island were examined using SCUBA and shore sampling in November 2004. It is one of […]

9. Reproductive strategies of sub-Antarctic lithodid crabs vary with habitat depth

   We present the first fecundity and egg size data for three species of lithodid crab from Antarctic waters south of the Polar Front, caught in the fisheries operating around the […]

10. Interpreting ancient ice in a shallow ice core from the South Yamato (Antarctica) blue ice area using flow modeling and compositional matching to deep ice cores

    We explore methods of dating a 101 m ice core from a bare ice ablation area in the Yamato Mountains, Dronning Maud Land, East Antarctica. There are two unknowns, the […]

11. Energetic outer zone electron loss timescales during low geomagnetic activity

    Following enhanced magnetic activity the fluxes of energetic electrons in the Earth’s outer radiation belt gradually decay to quiet-time levels. We use CRRES observations to estimate the energetic electron loss […]

12. Origins of plasmaspheric hiss

    Plasmaspheric hiss is an electromagnetic wave emission responsible for electron loss from the radiation belts, particularly in the slot region (2 < L < 3). There are two leading theories […]
