1. Peculiarities of Euphausia superba size composition in Statistical Subarea 48.2 (South Orkney Islands)

   Abstract:  Clarification of main tendencies of spatial changeability of size composition of E.superba was undertaken by means of comparision of various size groups of curstacean distribution in the region of the South Orkney islands and adjacent waters. Materials of 14 separte expeditions were used

3. Target strength of Antarctic krill

   Abstract:  In-situ measurements of individual krill target strength are presented (modal value =-69db). Net samples obtained immediately before the experiment indicate that the animals were reproductively mature and averaged 47.44mm in length. Results agree well with recent predictions of acoustic

4. Oceanic condition and zooplankton distribution/ abundance in Bransfield Strait during austral summer 1989/1990

   Abstract:  To delineate zooplankton distribution and abundance in Bransfield Strait, in relation to hydrographic condition, a total of 29 sampling stations was occupied for the CTD casts and plankton towings in a systematic grid from December 29, 1989 to January 7, 1990. Comparisons of temperature

5. Estimation of krill (Euphausia superba) mortality and production rate in the Antarctic peninsula region

   Abstract:  A net sampling survey for krill was carried out by RV ‘Meteor’ along the Antarctic Peninsula from 26 December 1989 to 14 January 1990. Results were compared with data of an identical survey with RV ‘Polarstern’ in 1987/88. Seasonal variation between summer and winter abundance/biomass

9. Small scale krill surveys: simulations based on observed euphausiid distributions

   Abstract:  An observed distribution of Meganyctiphanes norvegica aggregations is used to examine the effects of krill swarm orientation and shape on the success of two proposed survey designs. The simulation involves a number of random paths of parallel or radially arranged transects passing

10. Note on estimating abundance from acoustic data on individual krill aggregations

    Abstract:  The theoretical basis underlying estimation of krill abundance using echo-integration and aggregation information are briefly described. The chief differences of the two approaches are highlighted. It is concluded that the echo-integration approach is superior for the estimation of
