J.; Horaud, Mathilde; Kershaw, Joanna; Miller, Patrick J. O.; Øien, Nils Inge; Pallin, Logan J.; Rikardsen, Audun H. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-06)
      Migration patterns are fundamentally linked to the spatiotemporal distributions of prey. How migrating animals can respond to changes in their prey’s distribution and abundance remains largely unclear. During the last decade, humpback whales (Megaptera novaeangliae) used specific winter foraging sites in fjords of northern Norway, outside of their main summer foraging season, to feed on herring ...

    • Hungry during migration? Humpback whale movement from the Barents Sea to a feeding stopover in northern Norway revealed by photo-ID analysis 

      Ramm, Theresia (Master thesis; Mastergradsoppgave, 2020-06-01)
      In the last nine winters, a humpback whale feeding aggregation has been observed in the nearshore waters and fjords of northern Norway. This seasonal humpback whale occurrence is presumably driven by a shift in the overwintering distribution of Norwegian spring spawning (NSS) herring into these coastal areas. Eastern North Atlantic humpback whales feed during summer in relative remote regions in ...
