    • Ocean predation and mortality of adult Atlantic salmon 

      Strøm, John Fredrik; Rikardsen, Audun Håvard; Campana, Steven E.; Righton, David; Carr, Jonathan; Aarestrup, Kim; Stokesbury, Michael J.W.; Gargan, Patrick; Javierre, Pablo Caballero; Thorstad, Eva Bonsak (Journal article; Peer reviewed, 2019-05-27)
      Predation and mortality are often difficult to estimate in the ocean, which hampers the management and conservation of marine fishes. We used data from pop-up satellite archival tags to investigate the ocean predation and mortality of adult Atlantic salmon (Salmo salar) released from 12 rivers flowing into the North Atlantic Ocean. Data from 156 tagged fish revealed 22 definite predation events (14%) ...
    • An investigation of the robustness of distance measure-based supervised labelling of segmented remote sensing images 

      Kiærbech, Åshild (Master thesis; Mastergradsoppgave, 2019-06-03)
      Unsupervised clustering methods on remote sensing images have shown good results. However, this type of machine learning needs additional labelling to be an end-to-end classification in the same manner as traditional supervised classification. The automation of the labelling needs further exploration. We want to investigate the robustness of a supervised automatic labelling scheme by comparing a ...
    • On the relationship between global mean temperature in historical runs of Earth system models and equilibrium climate sensitivity 

      Haug, Sofie Flyvholm (Master thesis; Mastergradsoppgave, 2019-05-31)
      Equilibrium climate sensitivity (ECS) measures the long-term global surface temperature response due to a doubling of CO2 in the atmosphere. Estimates of ECS is not well constrained, 1.5-4.5C [Pachauri et al., 2014], and there is a wide spread between different Earth system models (ESMs). Recently it has been suggested that ECS can be constrained using an observed relationship between the statistical ...
