  • Bruk og misbruk av klimaframskrivninger 

    Sorteberg, Asgeir (CICERO Senter for klimaforskning, 2009)
    Forskere er avhengig av pålitelige klimaframskrivninger for å kunne si hvilke konsekvenser klimaforandringer får for mennesker og samfunn i framtiden. Men hva kan klimaframskrivninger brukes til og hvordan bør ...

  • Carbon to nutrient ratios in marine systems: understanding natural variability Studies of seasonal, inter-annual and regional variability 

    Frigstad, Helene (The University of Bergen, 2012-06-29)
    Ecological stoichiometry deals with the coupling of the carbon (C), nitrogen (N) and phosphorus (P) cycles at the base of the aquatic food webs. Variation in C:N:P stoichiometry is driven by a multitude of factors, and ...
