1. A comparison of Antarctic krill (Euphausia superba Dana) caught by nets and taken by macaroni penguins (Eudyptes chrysolophus Brandt): evidence for selection?

   Abstract:  Using stomach lavage samples from macaroni penguins (Eudyptes chrysolophus Brandt) breeding at Bird Island, South Georgia and concurrent net samples caught within the penguin foraging range, we examined the potential selection of different length and maturity stages of Antarctic krill

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

   Abstract:  Samples of Antarctic krill collected from six seabird species and Antarctic fur seal during February 1986 at South Georgia were compared to krill from scientific nets fished in the area at the same time. The length-frequency distribution of krill was broadly similar between predators and

3. Dynamics of Antarctic penguin populations in relation to inter-annual variability in sea-ice distribution

   Abstract:  To investigate the role of sea ice cover on penguin populations we used principal component analysis to compare population variables of Adélie (Pygoscelis adeliae) and chinstrap (Pygoscelis antarctica) penguins breeding on Signy Island, South Orkney Islands with local (from direct

4. The fish diet of black-browed albatross Diomedea melanophrys and grey-headed albatross D. chrysostoma at South Georgia

   Abstract:  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 and 1994. Fish represented 30% and 72% by mass of the diet of black-browed albatrosses and 14%

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

   Abstract:  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 large epipelagic cephalopods aggregate into highly mobile schools making them difficult to locate and

8. A history of the acquisition and analysis of sea-ice data by CCAMLR

   Abstract:  This paper was requested by WG-EMM in 1995 (SC-CAMLR-XIV, Annex 4, paragraph 6.49). In the early years of development of the ecosystem monitoring program sea ice data, especially derived from satellite images, was recognised as an important source of information for interpreting changes
