1. Spatial distribution of predator/prey interactions in the Scotia Sea: implications for measuring predator/fisheries overlap

   Abstract:  The measurement of spatial overlap between predators and fisheries exploiting a common prey source is dependent upon the measurement scale used and the use of inappropriate scales may provide misleading results. Previous assessments of the level of overlap between predators and fisheries

2. Conflict or co-existence? Foraging distribution and competition for prey between Adélie and chinstrap penguins

   Abstract:  Adélie (Pygoscelis adeliae) and chinstrap penguins (P. antarctica) are morphologically and ecologically very similar, have very similar diet and breed sympatrically in the Scotia Arc from the South Sandwich Islands to the Antarctic Peninsula. To investigate how these two species co-exist

3. Krill population dynamics in the Scotia Sea: variability in growth and mortality within a single population

   Abstract:  Understanding the demographics of Antarctic krill over large scales may be complicated by regional differences in the 11 processes that govern population structure. The influence of regional differences in growth and mortality on population size 12 structure was examined using data on

4. Current temperature conditions off South Georgia during recent years (satellite data on Subarea 48.3)

   Abstract:  Satellite monitoring of sea surface temperatures (SST) off South Georgia (Subarea 48.3) which includes both analysis of real-time data from vessels and buoy stations provides constant information on the temperature conditions of the area. Weekly SST maps constructed from GOES-E and

5. The US commercial krill fishery in Area 48: development, fishing patterns, and decision making

   Abstract:  A U.S. flagged commercial factory trawler, the Top Ocean, started fishing operations for krill (Euphausia superba) in Area 48 in July, 2000. This fishery has continued and expanded each year since the initial fishing trials. This paper presents information on the development, yields, and

6. Combined standardised indices of predator performance at Bird Island, South Georgia, 1973¬–2002

   Abstract:  Long-term data on the reproductive performance of krill predators at Bird Island, South Georgia where used to produce Combined Standardised Indices (CSI) that reflect processes operating over different time-scales. The output from all three CSIs indicated that in 2002 there were no

7. Are krill recruitment indices from meso-scale survey representative for larger areas?

   Abstract:  The present contribution uses data from German surveys in the 1980’ies and the US LTER programme which continuously collected krill demography data since 1993 during the austral summer season in the upstream area of the Elephant Island mesoscale survey. The intention was to compare the

10. CEMP indices 2002: analysis of anomalies and trends

    Abstract:  The CCAMLR Ecosystem Monitoring Program uses indices derived from data on indicator species and the environment collected by standard methods within the three Integrated Study Regions of the Convention Area. Standardised index values are re-calculated each year as new data become
