(Eds.), Filin, A., Hansen, J.R., Høines, Å., Marasaev, S. (Co-eds.) 2009. Joint Norwegian-Russian environmental status 2008. Report on the Barents Sea Ecosystem. Part II – Complete report. IMR/PINRO Joint Report Series, 2009(3), 375 pp. ISSN 1502-8828. Electronical version on internet portal Our report is also published on internet using the URL http://www.barentsportal.com. The web publication is identical to the printed report, but you will in addition find ads that supplements and broadens some aspects in the contents. Furthermore, you will find a Web Map Service which gives you the opportunity to have a more geographic focus on some of the thematic presentation of environmental issues, and e.g. add other maps on top for comparison. An interesting feature is the possibility to give your comments on all text and figures. Hopefully, these comments will stimulate to debates on environmental issues, condition and future development in the Barents Sea – or bring up questions on topics that are difficult to conceive or should be broaden more. If prosperous, the web publication will be the main form for updating and developing of the Joint Norwegian-Russian environmental status reports on the Barents Sea Ecosystem.
