description Forsgren, E., Christensen-Dalsgaard, S., Fauchald, P, Järnegren, J. & Næsje, T. F. 2009. Norwegian marine ecosystems – are northern ones more vulnerable to pollution from oil than southern ones? – NINA Report 514. 32 pp. The prospect of petroleum industry activities in northern Norwegian marine areas, from Lofoten and northwards, including the Norwegian part of the Barents Sea, is much debated. This report addresses the question whether the Lofoten-Barents Sea ecosystems are different and more vulnerable to oil pollution as compared to more southern Norwegian marine ecosystems. We summarise a literature review looking for evidence in relation to this. We found that there are a number of aspects which differ between the two areas, in particular with respect to biodiversity (lower in the north), species distributions, and ‘hot spot areas’ with high productivity and animal aggregations (especially significant in the north). Based on this knowledge we focus on the vulnerability of these ecosystems to pollution from oil, and discuss likely general and species specific differences in vulnerability between northern and southern Norwegian marine ecosystems. Cleaning up marine oil spills in remote, icy areas like the Arctic is particularly difficult. Moreover, the Lofoten-Barents Sea ecosystem appears, in several ways, more vulnerable to pollution from oil. This is due to, for instance, lower biodiversity, which has been suggested to be associated with lower resilience. Also, this area is the home of many valuable and vulnerable organisms. For example, the Lofoten-Barents Sea hosts large seabird colonies and contains the nursery area of important fishes. In addition, there are significant conflicts of interest between petroleum activities and other activities in the area, for example, important fisheries and nature conservation.

Norwegian marine ecosystems – are northern ones more vulnerable to pollution from oil than southern ones? – NINA Report 514. 32 pp. Oljeutvinning i nordlige norske havområder (fra Lofoten og nordover) har lenge vært omdiskutert. Denne rapporten tar for seg spørsmålet om de marine økosystemer i LofotenBarentshavet er forskjellige fra og mer sårbare for oljeforurensning enn områder lenger sør i Norge. I rapporten sammenfatter vi en litteraturgjennomgang av kunnskap relatert til dette. Vi fant flere aspekter som er forskjellige mellom disse økosystemene, for eksempel når det gjelder biodiversitet (lavere i nord), og forekomst av høyproduktive områder og ansamlinger av dyr (spesielt i nord). Basert på dette fokuserer vi på sårbarhet hos disse økosystemene med hensyn til oljeforurensing, og diskuterer sannsynlige generelle og artsspesifikke forskjeller i sårbarhet mellom de nordlige og sørlige norske områdene. Oppryddingsaksjoner i arktiske hav er meget vanskelige. Økosystemene i Lofoten-Barentshavet ser dessuten ut til å være mer sårbare for oljeforurensing av flere grunner. Dette skyldes blant annet at det trolig er mindre motstandskraft mot forstyrrelser i et artsfattigere system, og at dette området har mange spesielt verdifulle og sårbare arter. Lofoten-Barentshavet har mange store sjøfugl-kolonier, og er yngelområde for flere viktige fiskearter. I tillegg er det store interessekonflikter mellom oljeaktivitet og andre aktiviteter i området, som meget viktige fiskerier og naturvern. © Norsk institutt for naturforskning.
