1. A review on the feeding conditions of the baleen whales in the Southern Ocean

   Abstract:  Food habits of the southern baleen whales were reviewed being based on the published and unpublished data since 1946. Past geographical distributions of the krill in the whales stomach revealed that the frequency occurrence by krill size showed that the large krill(>50mm) occurs more

2. Distribution of salps near the South Shetland Islands; their ecological significance in the area

   Abstract:  Distribution and abundance of salps were studied near the South Shetland Islands during summer 1990/1991. Total salp biomass ranged between 0.1 and 2021.3 mg WW∙m-3 and was nearly equal to krill biomass in the area. Two species; Salpa thompsoni and Ihlea racovitzai were found, and the

3. Comparison of the distribution of particulate matters and the composition of particulate organic matter in suface waters between the coastal and oceanic areas off the northern South Shetland Islands in summer

   Abstract:  Biogenic silica (BSi), lithogenic silica (LSi), particulate organic carbon (POC) and nitrogen (PON), and chlorophyll a (Chl a) were measured in the surface waters (Author(s):  A. Shiomoto and H. Ishii (Japan) Title:  Comparison of the distribution of particulate matters and the

4. Some idea of numerical model for assessment of Euphausia superba biomass

   Abstract:  A numerical model is being developed for assessment of Euphausia superba in Antarctic Ocean, which consists of: (1)calculation of three dimensional current field using CCSR version (developed by Dr. Yamanaka of Center of Climate System Research, University of Tokyo) of the three

5. Report of an examination of the acoustic data from RV Eduardo L. Holmberg collected during the FIBEX study

   Abstract:  Data from the Eduardo L Holmberg FIBEX survey have been re-examined for incorporation into the BIOMASS Database in the approved standardised format. The results indicate the krill were concentrated to the western end of the South Orkney Islands. Density values are consistent with those

6. 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

7. 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:

8. 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

9. 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

10. 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
