1. Prediction of krill target strength by liquid prolate spheroid model

   Abstract:  A theoretical prolate spheroid liquid model is applied to predict the target strength (TS) of krill. Scattering patterns are shown to demonstrate orientation dependence of krill TS. Length-to- wavelength ratio (L/λ) dependencies of reduced (normalized by body length squared) target

2. Hydrographic flux in statistical Area 58 of ccamlr in the Southern Ocean

   Abstract:  This document submits the basic information on the hydrographic flux in Statistical Area 58. Those are surface geostrophic flow in the whole of Statistical Area 58, and vertical distributions of geostrophic flow along 37° E, 75° E,114° E and 155° E. Author(s):  M. Naganobu (Japan) Title:

3. Chlorophyll distributions around the South Shetland Islands

   Abstract:  Aim of this document is to supply a short information of chlorophyll distribution patterns around the South Shetland Islands in the Antarctic survey of R/V the Kaiyo Maru from 13 December 1990 to 11 January 1991 (Leg I) and from 16 January to 11 February 1991 (Leg II). In the north of

4. Orientation of Antarctic krill in an aquarium

   Abstract:  Acoustic methods appear to be the best way to estimate Antarctic krill abundance directly. Information on body orientation, however, is needed to obtain reliable krill acoustic target strength (TS) values, since TS varies with body orientation. Krill body orientation was measured in an

5. An address to citizen’s marine summit

   Abstract:  The main aims of CCAMLR are reviewed in an essay which discusses the advances in the effectiveness of harvesting, arising from developments in science and technology in comparison with the requirements of science to provide information for rational management. It is concluded that co

6. A note on the chlorophyll measurement by satellite remote sensing in the Antarctic Ocean

   Abstract:  This paper describes the usefulness of satellite ocean color remote sensing in the Antarctic Ocean by making a comparison between CZCS chlorophyll images and ship-measured chlorophyll concentrations in the sea area off Enderby Land, Antarctica. In addition, some characteristics of the

7. Peak mortality of krill, fished with midwater trawls and feasible criteria of krill trawls ecological safety

   Abstract:  The mathematical model of a fishery object contact against a mesh, while escaping through a trawl chafer, is presented. Based on it t the equations are provided to calculate the object elimination probability caused by cath and mortality in fishery operations. The coefficient of trawl

8. Estimation of chlorophyll distributions obtained from satellite images (Nimbus-7/CZCS) in the Antarctic Ocean

   Abstract:  Previous studies have established that ocean color information from Nimbus-7/CZCS{Coastal Zone Color Scanner) could be related to distribution of phytoplankton pigment (Chlorophyll-a + pheopigments) concentrations. CZCS data from polar regions have been utilized only a limited number

9. Krill length and age at maturity

   Abstract:  Data from several summer surveys to the Antarctic Peninsula region were analysed to calculate length and age at maturity for the Antarctic krill Euphausia superba. L50 values of 34.62 to 35.90 mm for female krill are the best estimates for the high spawning season. Males attain sexual

10. Antarctic krill, Euphausia superba Dana, demography studies in the seas of Sodruzhestvo and Cosmonauts (Indian Ocean sector of Antarctica)

    Abstract:  The materials on Euphausia superba biological state and size composition in the Indian Antarctic seas for the period from 1985 to 1990 are analyzed to form an opinion about its growth, life duration, as well as about the interannual variability in the above parameters. According to our
