2. Interpretation of polarisation behaviour of radar waves transmitted though Antarctic ice shelves

   We have collected polarimetric ice sounding radar data on Brunt, George VI and Ronne ice shelves using a vector network analyser as a continuous wave step-frequency radar. Being a wideband […]

3. A coordinated ground-based and IMAGE satellite study of quiet-time plasmaspheric density profiles

   Cold plasma mass density profiles in the plasmasphere have been determined for the geomagnetically quiet day of 19th August 2000 using the cross-phase technique applied to ground-based magnetometer data from […]

4. Near-surface turbulent fluxes in stable stratification: calculation techniques for use in general-circulation models

   Practically oriented flux-calculation techniques based on correction functions to the neutral drag and heat/mass transfer coefficients are further developed. In the traditional formulation, the correction functions depend only on the […]

5. Scavenging by megabenthos and demersal fish on the South Georgia slope

   The scavenging megafauna of the South Georgia and Shag Rocks slope in the south-west Atlantic (625-15 19 m) were investigated using autonomous baited camera systems. Two surveys were conducted: the […]

6. ULF Pc5-6 magnetic activity in the polar cap as observed along a geomagnetic meridian in Antarctica

   Latitudinal and diurnal distributions of spectral power and spatial coherency parameters of the geomagnetic variations in the Pc5-6 (1–6 mHz) frequency range are analyzed using data of magnetometer stations in […]

7. Distribution of cephalopods recorded in the diet of the Patagonian toothfish (Dissostichus eleginoides) around South Georgia

   The cephalopod component of the diet of Patagonian toothfish, Dissostichus eleginoides, around South Georgia was analysed from stomach contents collected between March and May 2000. Cephalopods occurred in 7% of […]

8. Unusual occurrence of Illex argentinus (Cephalopoda: Ommastrephidae) in the diet of albatrosses breeding at Bird Island, South Georgia

   In Southwest Atlantic waters, the short-finned squid Illex argentinus is distributed along the Patagonian shelf and slope, from approximately 22° to 54°S ( Haimovici et al., 1998). I. argentinus has […]

10. Pigmentation as a survival strategy for ancient and modern photosynthetic microbes under high ultraviolet stress on planetary surfaces

    Solar radiation is the primary energy source for surface planetary life, so that pigments are fundamental components of any surface-dwelling organism. They may therefore have evolved in some form on […]

11. Editorial: The International Journal of Astrobiology

    The launch of a new journal is appropriately like a space mission. It is the result of a scientific need, the inspiration of a group of committed scientists and technologists, […]

12. Data report: Diffuse spectral reflectance data from rise sites 1095, 1096, and 1101 and Palmer Deep sites 1098 and 1099 (Leg 178, western Antarctic Peninsula)

    The routine use of spectrophotometry on the sediment surfaces of archive halves of each section during the onboard sedimentological core description process is a great stride toward development of real-time […]
