    • Assessing the patchiness of early life stage of a fish stock (Gadus morhua) and its contribution to the stock recruitment 

      Dupont, Nicolas; Vikebø, Frode Bendiksen; Langangen, Øystein Ole Gahr (Peer reviewed; Journal article, 2022)
      Patchiness, defined as spatial heterogeneity in distribution of organisms, is a common phenomenon in zooplankton including ichtyoplankton. In heterogeneous landscapes, depending on the scale of prey and predatory distributions, ...

    • Coastal water darkening and implications for mesopelagic regime shifts in Norwegian fjords 

      Aksnes, Dag Lorents; Dupont, Nicolas; Staby, Arved; Fiksen, Øyvind; Kaartvedt, Stein; Aure, Jan (Journal article; Peer reviewed, 2009-07-28)
      The light regime of the water column has a strong structuring effect on aquatic food webs and it has been previously hypothesized that coastal water darkening has increased the success of tactile predators relative to ...

    • Micronekton biomass distribution, improved estimates across four north Atlantic basins 

      Klevjer, Thor A.; Melle, Webjørn Raunsgård; Knutsen, Tor; Strand, Espen; Korneliussen, Rolf; Dupont, Nicolas; Salvanes, Anne Gro Vea; Wiebe, Peter H. (Peer reviewed; Journal article, 2019)
      Distribution of micronekton was investigated during early summer of 2013, using data from a cruise covering the central parts of four north Atlantic basins, the Norwegian Sea (NS), Iceland Sea (ICS), Irminger Sea (IRS), ...

    • Plankton community structure and fish spawning area indicators in the Bay of Biscay, using Laser Optical Plankton Counter 

      Dupont, Nicolas; Planque, Benjamin (ICES CM Documents;2005/P:13, Working paper, 2005)
      In the Bay of Biscay, regular fisheries acoustic cruises are conducted to assess small pelagic fish stocks. Within the frame of the Bay of Biscay integrated project, measurements of additional biotic and abiotic variables ...

    • Sea ice, temperature, and prey effects on annual variations in mean lengths of a key Arctic fish, Boreogadus saida, in the Barents Sea 

      Dupont, Nicolas; Durant, Joel Marcel; Langangen, Øystein; Gjøsæter, Harald; Stige, Leif Christian (Peer reviewed; Journal article, 2020)
      Oceanographic conditions in the Arctic are changing, with sea ice cover decreasing and sea temperatures increasing. Our understanding of the effects on marine populations in the area is, however, limited. Here, we focus ...

    • Structure and functioning of four North Atlantic ecosystems - A comparative study 

      Melle, Webjørn Raunsgård; Klevjer, Thor A.; Drinkwater, Kenneth F.; Strand, Espen; Naustvoll, Lars Johan; Wiebe, Peter H.; Aksnes, Dag Lorents; Knutsen, Tor; Sundby, Svein; Slotte, Aril; Dupont, Nicolas; Salvanes, Anne Gro Vea; Korneliussen, Rolf; Huse, Geir (Peer reviewed; Journal article, 2020)
      The epi- and mesopelagic ecosystems of four sub-polar ocean basins, the Labrador, Irminger, Iceland and Norwegian seas, were surveyed during two legs from Bergen, Norway, to Nuuk, Greenland, and back to Bergen. The survey ...

    • The circumpolar impacts of climate change and anthropogenic stressors on Arctic cod (Boreogadus saida) and its ecosystem 

      Geoffroy, Maxime; Bouchard, Caroline; Flores, Hauke; Robert, Dominique; Gjøsæter, Harald; Hoover, Carie; Hop, Haakon; Hussey, Nigel E.; Nahrgang, Jasmine; Steiner, Nadja; Bender, Morgan; Berge, Jørgen; Castellani, Giulina; Chernova, Natalia; Copeman, Louise; David, Carmen; Deary, Alison; Divoky, George; Dolgov, Andrey; Duffy-Anderson, Janet; Dupont, Nicolas; Durant, Joël M.; Elliott, Kyle; Gauthier, Stéphane; Goldstein, Esther D.; Rolf, Gradinger; Hedges, Kevin; Herbig, Jennifer; Laurel, Ben; Loseto, Lisa; Maes, Sarah; Mark, Felix; Mosbech, Anders; Pedro, Sara; Petitt-Wade, Harri; Prokopchuk, Irina; Paul E, Renaud; Schembri, Sarah; Vestfals, Cathleen; Walkusz, Wojciech (Peer reviewed; Journal article, 2023)
      Arctic cod biomass are predicted. In most Arctic seas, the relative abundance of Arctic cod within the fish community will likely fluctuate in accordance with cold and warm periods. A reduced abundance of Arctic cod will ...
