Acoustic estimates of krill density at South Georgia, December/January 1998/99
Abstract: Dual frequency (38 and 120 kHz) acoustic data from grid surveys in two boxes to the north-west and north-east of South Georgia during December/January 1998/99 were used to estimate mean krill density there. Densities (east = 11.1 g m-2, west = 12.0 g m-2) were towards the lower end of

Estimates of global krill abundance based on recent acoustic density measurements and their implications for the calculation of precautionary catch limits and the designation of management areas
Abstract: The global abundance of krill is estimated using recent estimates of krill density from acoustic surveys and historical information on the overall range of krill. The biomass estimates fall between 64 and 137 million tonnes- at the low end of values that have been suggested in the past.

Potential effects of UV-B on krill – experimental and genetic studies
Abstract: We irradiated captive juvenile Euphausia superba in the laboratory with lower than spring surface levels of ultraviolet-B, ultraviolet-A and photosynthetically active radiation, in order to examine their response in terms of mortality and generalised activity. Levels of

Poor breeding success of the Adélie penguin at Béchervaise Island in the 1998/99 season
Abstract: This paper describes the diet and foraging behaviour of Ad6lie penguins at B6chervaise Island during 1998-99, a season of high chick mortality. One thousand nests perished in the three weeks following first hatch, when the chicks were very small. A total of 802 chicks reached crèche age

Correlation between krill and Champsocephalus gunnari stocks in the South Georgia Area 48.3
Abstract: After almost a ten-year gap in fishing for Champsocephalus gunnari in the area of South Georgia and Shag Rocks, the Russian large-sized trawler ZAKHAR SOROKIN (the MOONZUND-type) attempted a short-time fishing operation in February-March, 1999. Overall, 85 pelagic trawlings yielded 264

Light levels experienced by foraging Antarctic fur seals, Arctocephalus gazella
Abstract: This study examined the feasibility of using time depth recorders (TDRs) to measure light levels experienced by a diving marine mammal. TDRs were deployed on 10 female Antarctic fur seals (Arctocephalus gazella) at Bird Island, South Georgia (54° 00' S 38° 02' W) in the 1994/5

Influence of sampling protocol on diet determination of gentoo penguins, Pygoscelis papua and Antarctic fur seals, Arctocephalus gazella
Abstract: The influence of two sampling protocols on diet determination of two marine predators, the Gentoo penguin Pygoscelis papua and Antarctic fur seal Arctocephalus gazella, was investigated. The collection of diet samples on three occasions over a two week period was compared with collecting
