1. A comparison of EISCAT and Dynasonde measurements of the auroral ionosphere

   Incoherent-scatter radar and ionospheric sounding are powerful and complementary techniques in the study of the Earth’s ionosphere. The work presented here involves the use of the Tromsø Dynasonde as a […]

2. Antarctic Peninsula granitoid petrogenesis: a case study from Mount Charity, north-eastern Palmer Land

   At Mount Charity, north-eastern Palmer Land, Rb–Sr whole-rock dating has identified three successive phases of granitoid emplacement in Triassic (232 ± 4 Ma), Jurassic (168 ± 1 Ma), and Cretaceous […]

3. An assessment of the role of the marginal ice zone in the carbon cycle of the Southern Ocean

   The dense phytoplankton blooms observed in earlier studies in the Southern Ocean Marginal Ice Zone (MIZ) may not be representative of all regions, so that some previous assessments of the […]

4. Interpolation errors in UV–visible spectroscopy for stratospheric sensing: implications for sensitivity, spectral resolution, and spectral range

   UV–visible measurements of stratospheric constituents require the ratio of a pair of spectra to be determined. If their wavelength calibrations differ and if an array detector is used, at least […]

5. Cephalopods and mesoscale oceanography at the Antarctic Polar Front:satellite tracked predators locate pelagic trophic interactions

   Predator data and exploratory fishing in the Scotia Sea have revealed the presence of cephalopod stocks in the Antarctic Polar Frontal Zone (PFZ). This is a vast, remote region where […]

6. Role as Consumers

   Cephalopods are voracious, versatile predators. They generally have a short life span and a single spawning event followed by death. Populations are subject to dramatic fluctuations and their impact on […]

7. Diurnal and seasonal occurrence of polar patches

   Analysis of the diurnal and seasonal variation of polar patches, as identified in two years of HF-radar data from Halley, Antarctica during a period near sunspot maximum, shows that there […]

9. Experimental fracture and mechanical properties of Antarctic ice: preliminary results

   An experimental study of the fracture mechanics and rheology of ice from the Ronne Ice Shelf, Antarctica, is currently being undertaken. The apparent critical stress-intensity factor (or apparent fracture toughness, […]

10. Krill caught by predators and nets: differences between species and techniques

    Samples of Antarctic krill collected from 6 seabird species and Antarctic fur seal during February 1986 at South Georgia were compared to krill from scientific nets fished in the area […]

11. The fish diet of black-browed albatross Diomedea melanophris and grey-headed albatrossD. Chrysostoma at South Georgia

    The fish component of the diet of black browed and grey-headed albatrosses at South Georgia was investigated by intercepting 155 meals from adults arriving to feed chicks during February 1986 […]

12. The diet of Antarctic fur seals Arctocephalus gazella during the breeding season at South Georgia

    The diet of lactating female Antarctic fur sealsArctocephalus gazella at South Georgia was investigated during the pup-rearing period (January/March) of 1991–1994. Antarctic krillEuphausia superba was the main prey item, occurring […]
