Stabile isotoper (karbon og nitrogen) analyse av Barentshavet og Polhavet Økosystemer

Arbeider med trofiske interaksjoner i Barentshavet - steg mot en integrert Ecosystem Assessment (tibia) prosjekt, og Strategisk Intitiativ Arktis (SI_ARCTIC). Disse prosjekter vil analysere økosystemkomponenter fra plankton til fisk til bunndyr vha sammensetningen av stabile isotoper, og bruke resultatene til å spore pelagisk-bentiske kobling, trofisk tilkobling og strukturering, og endringer i økosystemet. Resultatene skal brukes til å undersøke strukturen i økosystemene i de ulike områdene, og finne ut av, om det er mulig å måle effekten av miljøendringer over Barentshavet fra sør til nord, og i den norske Polhavet.
