Monitoring
To ensure the comparability of observation results and to estimate seasonal and year-to year variations in oceanographic variables, it was suggested in Stockholm as early as 1899 that measurements should be made at standard depths and on standard sections. At the beginning of the 20th century observations started on the Kola Section in the Barents Sea (Knipovich 1906), and by the 1930s, a network of such sections had been developed in the area (Figure 3.2.1).

Standard sections contain some of our longest marine time series, reaching back more than 100 years.
At the beginning of the 20-th century observations started on the Kola Section in the Barents Sea (Knipovich 1906), and by the 1930s, a network of such sections had been developed in the area (Figure 3.2.1). During the last decades, zooplankton has also been sampled at some of these sections. An ove...

Area-surveys are conducted throughout the year. The number of vessels in each survey differs, not only between surveys but may also change from year to year for the same survey. However, most surveys are conducted with only one vessel. It is not possible to measure all ecosystem components during each survey. Also, an investigation should not take too long time in order to give a synoptic picture ...

The survey is carried out during February-early March, and covers the main cod distribution area in the Barents Sea. The coverage is in some years limited by the ice distribution. Three vessels are normally applied, two Norwegian and one Russian. The main observations are made with bottom trawl, pelagic trawl, echo sounder and CTD. Plankton studies have been done in some years. Cod and haddock ar...

The main spawning grounds of North East Arctic cod are in the Lofoten area. Echosounder equipment was first used in 1935 to detect concentrations of spawning cod, and the first attempt to map such concentrations was made in 1938 (Sund, 1938). Later investigations have provided valuable information on the migratory patterns, the geographical distribution and the age composition and abundance of the...

The BarnetsPortal is a combined web site. It consist of two main elements; presentation of the Joint Norwegian-Russian environmental status report and the Map service. The Report will be updated at regular intervals - initially started with data from 2008. The Map service will continually publish environmental theme data as they become available. Read more...
More than 100 experts from a total of 9 Russian and 20 Norwegian institutions have participated in the preparation of the report, and the work has been organized in 13 expert groups. The work has been led by Sevmorgeo and PINRO on Russian side and on Norwegian side by the Institute of Marine Research and the Norwegian Polar Institute..
