Survey report from the joint Norwegian/Russian ecosystem survey in the Barents Sea August-October 2004, Volume 1
MetadataVis full innførsel
The 2nd joint ecosystem survey was carried out during the period 1st of August to 4th of October 2004. This survey encompasses various surveys that previously have been carried out jointly or at national basis. Joint investigations include the 0-group survey, the acoustic survey for pelagic fish (previously known as the capelin survey), and the investigations on young Greenland Halibut north and east of Spitsbergen. Oceanographic investigations have always formed a part of these surveys, and studies on plankton have been included for many years. In recent years, observations of sea mammals, seabirds, bottom fishes, and benthos have been included. Consequently, from 2003, these surveys were called "ecosystem surveys". The present report from the survey will cover many but not all the aspects of the survey. Main focus is on the hydrographical conditions of the Barents Sea, the results from the 0-group investigations and from the acoustic investigation on pelagic fish (capelin, young herring and polar cod). Materials on sea mammals and seabird observations are also presented in volume 1 of the report. Results from the investigations on plankton, bottom fishes and benthos will only be briefly mentioned, since the reporting of these investigations will have to await further working up of material in the laboratories. Those investigations will be included in volume 2. The 1st volume of the report was made during a meeting between scientists participating in the survey, in Kirkenes 5-8th October.
