1. Localized structure in the cusp and high-latitude ionosphere: a modelling study

   The ionospheric signature of a flux transfer event (FTE) seen in EISCAT radar data has been used as the basis for a modelling study using a new numerical model of […]

2. Comparative thermal tolerance of herbivorous and predatory beetles on South Georgia, Sub-Antarctic

   On the sub-Antarctic island of South Georgia the field distributions of two herbivorous perimyloid beetles Hydromedion sparsutum and Perimylops antarcticus overlap with the latter occurring at higher altitudes. An introduced […]

3. Krill-copepod interactions at South Georgia, Antarctica, II. Euphausia superba as a major control on copepod abundance

   Euphausia superba (hereafter ‘krill’) and copepods are major zooplankton taxa in the Southern Ocean, but there is little information on how they interact. This paper investigates their coincidence across a […]

4. On the SuperDARN autocorrelation function observed in the ionospheric cusp

   The SuperDARN radars are proving to be a very powerful experimental tool for exploring solar wind-magnetosphere-ionosphere interactions. They measure the autocorrelation function (ACF) of the transmitted signal backscattered from the […]

5. Microsatellite analysis of genetic diversity in the squid Illex argentinus during a period of intensive fishing

   Levels of genetic diversity and population differentiation were examined in temporally (1990 to 1997) and geographically separated samples of the argentine short-finned squid Illex argentines using 7 microsatellite loci. Number […]

6. Highly polymorphic microsatellite loci of the heavily fished squid genus Illex (Ommastrephidae).

   Ommastrephid squid of the genus Illex form an important trophic component of large areas of the Atlantic ocean, both as prey for fish, seabirds, whales and other cephalopods, and as […]

7. Mapping sub-pixel fluvial grain sizes with hyperspatial imagery

   This paper presents an investigation of image texture approaches for mapping sub-pixel fluvial grain-size features from airborne imagery, allowing for the rapid acquisition of surface sand and coarse fraction (>1.41 […]

8. Air–snow transfer of nitrate on the East Antarctic Plateau – Part 1: Isotopic evidence for a photolytically driven dynamic equilibrium in summer

   Here we report the measurement of the comprehensive isotopic composition (δ15N, Δ17O and δ18O) of nitrate at the air–snow interface at Dome C, Antarctica (DC, 75°06′ S, 123°19′ E), and […]

9. First record of Trichoceridae (Diptera) in the maritime Antarctic

   During the austral summer of 2006–07, abundant Diptera were found in the sewage system of the Base Científica Antártica Artigas on King George Island. These are here identified as Trichocera […]

10. Laser-derived, particle size data from CRP-2/2A: implications for sequence and seismic stratigraphy

    Gravel-free, high-resolution (1-metre spacing, 32 channel) particle size data from the CRP-2/2A drill core indicate that many of the diamictites were likely deposited from floating ice. Textural dislocations occur at […]
