    • Fatty acid composition of the postlarval daubed shanny (Leptoclinus maculatus) during the polar night 

      Pekkoeva, Svetlana N.; Murzina, Svetlana A.; Nefedova, Zinaida A.; Falk-Pedersen, Stig; Berge, Jørgen; Lønne, Ole Jørgen; Nemova, Nina N. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-23)
      Recent discoveries of high levels of biological activity in the Arctic marine ecosystems during the polar night raise questions regarding the ecophysiology of the pelagic postlarval daubed shanny Leptoclinus maculatus. Of special interest is the composition of the lipid sac—a unique feature not found in other Arctic fishes. Analysis of the fatty acid content of major classes of lipids as membrane—total ...

    • First records of Atlantic mackerel (Scomber scombrus) from the Svalbard archipelago, Norway, with possible explanations for the extension of its distribution 

      Berge, Jørgen; Heggland, Kristin N.; Lønne, Ole Jørgen; Cottier, Finlo R.; Hop, Haakon; Gabrielsen, Geir W.; Nøttestad, Leif; Misund, Ole Arve (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-03)
      Atlantic mackerel (Scomber scombrus) were recorded in Isfjorden, Svalbard (78˚15ʹ N, 15˚11ʹ E) in late September 2013. This record is the northernmost known occurrence of mackerel in the Arctic and represents a possible northward expansion (of ca. 5˚ latitude) of its distributional range. The examined specimens of mackerel were between 7 and 11 years old, with a mean size of 39 cm and a mean ...

    • In the dark: a review of ecosystem processes during the Arctic polar night 

      Berge, Jørgen; Renaud, Paul; Darnis, Gérald; Cottier, Finlo; Last, Kim; Gabrielsen, Tove M.; Johnsen, Geir; Seuthe, Lena; Weslawski, Jan Marcin; Leu, Eva; Moline, Mark A.; Nahrgang, Jasmine; Søreide, Janne; Varpe, Øystein; Lønne, Ole Jørgen; Daase, Malin; Falk-Petersen, Stig (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-28)
      Several recent lines of evidence indicate that the polar night is key to understanding Arctic marine ecosystems. First, the polar night is not a period void of biological activity even though primary production is close to zero, but is rather characterized by a number of processes and interactions yet to be fully understood, including unanticipated high levels of feeding and reproduction in a ...

    • Introduction to the special issue on polar night studies conducted onboard RV Helmer Hanssen in the Svalbard area
