1. Effects of the Antarctic Circumpolar Current on fishing for squid (Illex Argentinus) in the Atlantic sector of the Southern Ocean

   Abstract:  The paper introduces several approaches to assessment of hydrological situation in the Atlantic sector of the Southern Ocean (the South-West Atlantic). The analysis of the SST maps suggests that hydrological factors depend on the intensity of two currents, the Antarctic Circumpolar

2. Trends of Antarctic fur seal population at SSSI No. 32, Livingston Island, South Shetlands, Antarctica

   Abstract:  We update in this paper the previously reported model for the Antarctic fur seal Arctocephalus gazella population breeding at Cape Shirreff and San Telmo Islets (SSSI No.32), Livingston Island, South Shetland, Antarctica. We also discuss the current reliability of the model and related

3. Estimation of krill biomass from an acoustic survey carried out in 1986, during a study of predator–prey interactions around the western end of South Georgia

   Abstract:  An acoustic survey, designed to study the distribution of shore-breeding, marine predators and their pelagic prey, was carried out in 1986 around the western end of South Georgia. This paper describes how this acoustic data has been used to estimate krill biomass of part of the original

4. Underwater noises produced by research vessels (some comments on acoustic sampling protocol for the Area 48 synoptic survey

   Abstract:  The underwater vessel noise levels perceived by the echosounder EK-500 transducers of three Russian research vessels have been presented. These data have been compared to the estimate of the underwater noise level, produced by the Icelandic R/V B.Saemundsson.. Underwater noise level

5. Interannual variation in the autumn diet of the gentoo penguin Pygoscelis papua at Laurie Island, Antarctica

   Abstract:  The diet of the gentoo penguin Pygoscelis papua was investigated during three different autumn periods at Laurie Island, South Orkney Islands (60°46’S, 44º42’W), Antarctica. Stomach contents of migrant adults were sampled during 1993, 1995 and 1996. Fish were the most important prey by

6. 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

8. 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.

9. The Second International Krill Symposium

   Abstract:  This background paper consists of the agenda and information for the Second International Symposium on Krill which has been partially sponsored by CCAMLR. The symposium will be held at the University of California, Santa Cruz, from 23–27 August 1999. Further information can be found on

10. 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
