    • Atferdsreaksjoner hos Atlantisk torsk (Gadus morhua) som følge av seismikkskyting 

      Walle, Anette (Master thesis; Mastergradsoppgave, 2020-05-15)
      Det har vært en betydelig økning av antropogene lydkilder i akvatiske miljøer de siste 30 årene, deriblant seismiske undersøkelser. Seismikk er en lavfrekvent lyd som har evne til å bre seg over store områder og det er derfor knyttet bekymring til hvorvidt det kan ha negative konsekvenser for marine organismer. I dette studiet har vi undersøkt hvorvidt seismikk kan føre til atferdsendringer hos ...
    • Rekruttering til fiskeri i Lebesby kommune. Hvordan har reguleringssystemet påvirket sysselsettingssystemet i fiske i et lokalsamfunn i Lebesby? 

      Rasmussen, Sofie Krogh (Master thesis; Mastergradsoppgave, 2020-05-15)
      Fiskeri har alltid vært viktig for lokalsamfunnene langs kysten og vært med på å skape levedyktige samfunn. Sysselsettingssystemet har lenge vært under endring og gått fra et tradisjonelt sysselsettingssystem til et mer moderne. Utviklingen med ny teknologi, adgangsbegrensninger og kvoter i fiskeriene har ført til effektivisering og bedre lønnsomhet. Det har også ført til færre fartøy og fiskere ...

    • Amorphous material in experimentally deformed mafic rock and its temperature dependence: Implications for fault rheology during aseismic creep and seismic rupture 

      Marti, Sina; Stünitz, Holger; Heilbronner, Renee; Plümper, Oliver (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-20)
      Amorphous materials are frequently observed in natural and experimentally produced fault rocks. Their common occurrence suggests that amorphous materials are of importance to fault zone dynamics. However, little is known about the physico-chemical impact of amorphous materials on fault rheology. Here we present deformation experiments on mafic fault rock, where amorphous material forms due to intense ...
