3. Development of foraging behaviour and evidence of extended parental care in the gentoo penguin (Pygoscelis papua)

   Abstract:  We used radio telemetry and observations to study the activity patterns and behaviour of gentoo penguin chicks during their “fledging period”; defined as the time between a chick’s first trip to sea and its final dispersal from the breeding colony. Our study was conducted at a colony of

4. Impact of predation by Cape fur seals Arctocephalus pusillus on Cape gannets Morus capensis at Malgas Island, Western Cape, South Africa

   Abstract:  Cape fur seals (Arctocephalus pusillus) were estimated to kill some 6 000 Cape gannet (Morus capensis) fledglings around Malgas Island in the 2000/01 breeding season, 11 000 in 2003/04 and 10 000 in 2005/06. This amounted to about 29%, 83% and 57% of the overall production of fledglings

5. Demography of Antarctic krill in the Lazarev Sea (Subarea 48.6) in the 2005/06 season

   Abstract:  A standardized krill net sampling survey was conducted in the Lazarev Sea (Subarea 48.6) in December 2005. Krill densities were low in the Lazarev Sea. No substantial day/night differences were observed in the catches. Spatial distribution of krill density and size/age classes is

6. Descriptive analysis of mesopelagic backscatter from acoustic data collected in the Ross Sea

   Abstract:  This report presents results from a pilot study to investigate the use of acoustics to estimate middle trophic level prey organisms (e.g., krill and mesopelagic fish) in the Ross Sea. Single frequency (38 kHz) acoustic data were available from New Zealand longline vessels participating

7. A spatial multi-species operating model (SMOM) of krill–predator interactions in small-scale management units in the Scotia Sea

   Abstract:  A Spatial Multi-species Operating Model (SMOM) of the underlying krill-predator-fishery dynamics is developed in response to requests for scientific advice regarding the subdivision of the precautionary catch limit for krill among 15 small-scale management units (SSMUs) in the Scotia Sea

8. Time series of Drake Passage Oscillation Index (DPOI) from 1952 to 2006, Antarctica

   Abstract:  An assessment of the environmental processes influencing variability in the recruitment and density of Antarctic krill (Euphausia superba DANA) is important as variability in krill stocks affects the Antarctic marine ecosystem as a whole. Naganobu et al. (1999) had assessed variability

9. Progress towards a trophic model of the ecosystem of the Ross Sea, Antarctica, for investigating effects of the Antarctic toothfish fishery

   Abstract:  We report on the further development of a carbon-budget trophic-model of the Ross Sea with which to investigate effects of the fishery for Antarctic toothfish (Dissostichus mawsoni). The Ross Sea is a low primary production system, with production being localised in space and time. In

10. An overview of a large ecosystem survey of the southwest Indian Ocean sector of the Southern Ocean (CCAMLR Division 58.4.2)

    Abstract:  This document outlines the preliminary results of an Australian survey of CCAMLR Division 58.4.2 (the South West Indian Ocean Sector of the Southern Ocean 30-80°E) in January-March 2006, which was designed around an acoustic biomass survey for krill and a large-scale oceanographic survey
