Oil transportation along the coastline of northern Norway has been one of the hottest topics discussed in the Barents Region for the recent two years. It is also an important issue of today"s political agenda and bilateral discussion between Norway and Russia. This Report is an extended and updated version of a similar report published back in 2003. The purpose of this new edition is to provide the reader with new and additional information. We believe this is of crucial importance as the organisation of the oil shipment through the Barents Sea is constantly changing. The new report presents the ongoing oil transportation activities in the Russian part of the Barents Region. Moreover, the report gives an overview of the existing reserves of hydrocarbons, oil production facilities, transportation routes (oil loading terminals, transshipment schemes, export routes) and transport systems (railways, waterways and pipelines), as well as some environmental aspects of the oil shipment (environmental policies and prevention systems). The authors also give their reflections and comments about oil transportation safety, and point out factors tat they believe are essential to achieve efficient oil spill protection inside the Russian Barents and further along the Norwegian coast. The report is prepared and published by Bioforsk Svanhovd (former Svanhovd Environmental Centre) with support from the Norwegian Barents Secretariat and the WWF Arctic Programmme. The report is also available in Russian.

Here we report on low molecular weight organic acids in root exudates and soil solutions of Norway spruce and silver birch grown in rhizoboxes, sterile microcosms and the field. Monocarboxylic acids dominated in all three experimental systems. Formic, shikimic and oxalic acids were found in both spruce and birch microcosms. Fumaric acid was exclusive for spruce, while lactic, malonic, butyric and phthalic acids were only found in the birch microcosms. In spruce rhizoboxes oxalic, lactic, formic, butyric and pthalic acids were found. In addition, citric, adipic, propionic, succinic and acetic acids were observed in the rhizosphere of birch. Behind root windows in the field, only oxalic and lactic acids were found in the rhizosphere of spruce fine roots, whereas also formic and phthalic were observed close to birch fine roots, all at low concentrations. The rhizosphere of mycorrhizal short roots of birch contained butyric acid along with the acids observed for birch fine roots. Our results emphasise that characteristics of both the trees e.g. species, developmental stage, root density, mycorrhizal status, and the experimental system, i.e. growth conditions are important for the composition and the amount of organic acids. We conclude that the rhizosphere of birch contains more organic acids at higher concentrations than spruce. (C) 2004 Elsevier Ltd. All rights reserved.

Tre typer organisk materiale, torv, hage/park-avfallskompost og kloakkslamkompost (1/3 kloakkslam + 2/3 granbark) ble sammenlikna som tilsetning til rotsonelaget på sandbaserte USGA-greener i et lysimeterforsøk på Planteforsk Landvik i 2003-2004. Kontrollruter med rein sand, uten organisk tilsetning, etablerte seg 2-3 måneder seinere og hadde i denne perioden signifikant større utvasking av gjødselnitrogenenn enn ruter med organisk materiale. Ruter med hage/parkavfallskompost etablerte seg raskere, men hadde også større utvasking av N,P og K, enn ruter med torv eller kloakkslamkompost. Til tross for svært forskjellige pH-verdier, ble ruter med torv og ruter med hage/parkavfallskompost likt angrepet av rotdreper(Gaeumannomyces graminis), mens ruter uten organisk materiale og ruter med kloakkslamkompost var praktisk talt fri for denne sjukdommen. I middel for første år etter såing hadde ruter med kloakkslamkompost best greenkvalitet.
