    • Implications of tag positioning and performance on the analysis of cetacean movement 

      Mul, Evert; Blanchet, Marie-Anne; Biuw, Martin; Rikardsen, Audun H. (Journal article; Peer reviewed, 2019)
      Background Satellite-linked animal-borne tags enable the study of free-ranging marine mammals. These tags can only transmit data while their antenna is above the surface for a sufficient amount of time. Thus, the position ...

    • Killer whales are attracted to herring fishing vessels 

      Mul, Evert; Blanchet, Marie-Anne; McClintock, Brett; Grecian, James; Biuw, Martin; Rikardsen, Audun H. (Peer reviewed; Journal article, 2020)
      ABSTRACT: Marine mammals and fisheries often target the same resources, which can lead to operational interactions. Potential consequences of operational interaction include entanglements and damaged or reduced catches but ...
