1. Near-shore acoustic surveys for Antarctic krill at South Georgia, January 2004

   Abstract:  Dual frequency (120 and 38 kHz) acoustic surveys were conducted around the Willis Islands and off the Barff Peninsula, South Georgia, from a 59 foot yacht in January 2004. The purpose of the surveys was to determine krill density near shore, in regions that have not traditionally been

2. Dynamoe and albatross papers 2003–2004

   Abstract:  This list of publications is for information only; it comprises a set of BAS papers that have relevance to the work of WG-EMM, but which do not relate directly to the current agenda. These papers were produced by two BAS core funded science programmes: Dynamics and Management of Ocean

3. Proposal for an acoustic krill biomass survey in CCAMLR Division 58.4.2

   Abstract:  This document outlines plans by Australia to conduct an acoustic biomass survey for krill in CCAMLR Division 58.4.2 (the South West Indian Ocean Sector) in January-March 2006. The survey is intended to produce a new estimate of B0 for this Division so that a revised precautionary catch

4. Interannual variation in the summer diet of Adélie penguin (Pygoscelis adeliae) at Edmonson Point

   Abstract:  Diet sampling of Adélie penguins (Pygoscelis adeliae) was carried out at two colonies, in the Ross Sea, Antarctica, to study the feeding ecology of this species for the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) Ecosystem Monitoring Program. The study

5. CPUE values derived from Soviet fishery statistics as indicators of Antarctic krill density fluctuations in 1977–1991

   Abstract:  The average CPUE values, annual and calculated for the periods of 1977-1986 and 1986- 1991 are considered. It is assumed that these values adequately describe trends in krill density fluctuations. Rather high stability of the values investigated is revealed. It is proposed that krill

6. Broadbandwidth sound scattering and absorption from krill (Meganyctiphanes norvegica), Mysids (Praunus flexuousus and Neomysis integer) and shrimp (Crangon crangon)

   Abstract:  Sound scattering and absorption measurements were made of Northern krill (Meganyctiphanes norvegica) over the acoustical bandwidth of 30 to 210 kHz and compared to similar scattering measurements made of Antarctic krill (Euphausia superba; Demer and Conti, 2003a). The measurements of

7. Sounds like more krill

   Abstract:  Antarctic krill, Euphausia superba, comprise the foundation of the food-web in the Southern Ocean and are the target of a large fishery. Recently, the total abundance of krill in the Scotia Sea was estimated from an international echosounder and net survey (CCAMLR 2000) to be 44.3

8. Report of scientific observations of commercial krill harvest aboard the Japanese stern trawler Chiyo Maru No. 5 2 August 2003–21 September 2003

   Abstract:  Japan has deployed one scientific observer on a Japanese krill trawler, Chiyo Maru No. 5, from 4 August 2003 to 21 September 2003. The observation was essentially undertaken following the CCAMLR Scientific Observers Manual. Summary of the fishing efforts, processing, fish by-catches,

9. Short note: report of bacterial infectious Antarctic krill (Euphausia superba) in South Georgia

   Abstract:  We report of affected Antarctic krill (Euphausia superba) observed during the observation onboard the F/V Chiyo Maru No.5, from 08/08/03 to 17/09/03 in South Georgia region.

10. Characteristics of seasonal variation in diurnal vertical migration and aggregation of Antarctic krill (Euphausia superba) in the Scotia Sea, using the Japanese fishery data

    Abstract:  We examined seasonal variation in CPUE (catch per volume of trawled water) and diurnal vertical migration of Antarctic krill (Euphausia superba) associated with the brightness categories of the day based upon the angles between the center of the sun and the celestial horizon on the
