    • Latitudinal, seasonal and depth-dependent variation in growth, chemical composition and biofouling of cultivated Saccharina latissima (Phaeophyceae) along the Norwegian coast 

      Forbord, Silje; Matsson, Sanna; Brodahl, Guri Ellila; Bluhm, Bodil; Broch, Ole Jacob; Handå, Aleksander; Metaxas, Anna; Skjermo, Jorunn; Steinhovden, Kristine; Olsen, Yngvar (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-23)
      The Norwegian coastline covers more than 10° in latitude and provides a range in abiotic and biotic conditions for seaweed farming. In this study, we compared the effects of cultivation depth and season on the increase in biomass (frond length and biomass yield), chemical composition (protein, tissue nitrogen, intracellular nitrate and ash content) and biofouling (total cover and species composition) ...

    • Temporal dynamics of carbon sequestration in coastal North Atlantic fjord system as seen through dissolved organic matter characterisation 

      Mathew, K Avarachen; Ardelan, Murat Van; Villa Gonzalez, Susana; Vadstein, Olav; Sajith Vezhapparambu, Veena; Leiknes, Øystein; Mankettikkara, Rahman; Olsen, Yngvar (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-19)
      Fjord systems in higher latitudes are unique coastal water ecosystems that facilitate the study of dissolved organic matter (DOM) dynamics from surface to deeper waters. The current work was undertaken in the Trondheim fjord characterized by North Atlantic waters, and compared DOM fractions from three depths - surface (3 m), intermediate (225 m) and deep (440 m) in four seasons, from late spring to ...
