1. 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 […]

2. 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 […]

3. 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 […]

5. 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, […]

6. 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 […]

7. 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 […]

8. 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 […]

10. Giant sediment drifts on the continental rise west of the Antarctic Peninsula

    Multichannel seismic reflection profiles from the continental rise west of the Antarctic Peninsula between 63° and 69°S show the growth of eight very large mound-shaped sedimentary bodies. MCS profiles and […]

11. Geometry, motion and mass balance of Dyer Plateau, Antarctica

    Geodetic surveying and ground-based radar profiling were used to determine geometry and surface motion of the ice sheet on the Dyer Plateau, Antarctica, in the vicinity of an ice-core site […]

12. Monzonite suites: the innermost Cordilleran plutonism of Patagonia

    In Patagonia a Triassic-Early Jurassic Cordilleran interior magmatic belt preceded the widespread eruption of Middle Jurassic syn-extensional rhyolites. Two plutons (La Calandria and La Leona) represent the easternmost plutonic rocks […]
