  • Large mesopelagic fishes biomass and trophic efficiency in the open ocean 

    Irigoien, Xabier; Klevjer, Thor A.; Røstad, Anders; Martinez, U.; Boyra, G.; Acuna, J. L.; Bode, A.; Echevarria, F.; Gonzalez-Gordillo, J. I.; Hernández-León, Santiago; Augsti, S.; Aksnes, Dag Lorents; Duarte, C. M.; Kaartvedt, Stein (Nature Publishing Group, 2014-02-07)
    With a current estimate of ~1,000 million tons, mesopelagic fishes likely dominate the world total fishes biomass. However, recent acoustic observations show that mesopelagic fishes biomass could be significantly larger ...
  • Mesoscale Eddies Are Oases for Higher Trophic Marine Life 

    Godø, Olav Rune; Samuelsen, Annette; Macaulay, Gavin J.; Patel, Ruben; Hjøllo, Solfrid Sætre; Horne, John; Kaartvedt, Stein; Johannessen, Johnny A. (Public Library of Science, 2012-01-17)
    Mesoscale eddies stimulate biological production in the ocean, but knowledge of energy transfers to higher trophic levels within eddies remains fragmented and not quantified. Increasing the knowledge base is constrained ...
  • Vertical distribution and trophic interactions of zooplankton and fish in Masfjorden, Norway 

    Giske, Jarl; Aksnes, Dag Lorents; Balino, Beatriz M.; Kaartvedt, Stein; Lie, Ulf; Nordeide, Jarle Tryti; Salvanes, Anne Gro Vea; Wakili, Sami M.; Aadnesen, Agnes (The University of Bergen, 1990)
    The distribution, biomass, and predator-prey relationships of the pelagic assemblage in Masfjorden, western Norway, was studied in January 1989. The pelagic biomass was dominated by particulate organic matter. Biomasses ...
