• Atlantic Water Pathways Along the North-Western Svalbard Shelf Mapped Using Vessel-Mounted Current Profilers 

      Menze, Sebastian; Ingvaldsen, Randi Brunvær; Haugan, Peter M.; Fer, Ilker; Sundfjord, Arild; Beszczynska-Moeller, Agnieszka; Falk-Petersen, Stig (Journal article; Peer reviewed, 2019)
      A large amount of warm Atlantic water (AW) enters the Arctic as a boundary current through Fram Strait (West Spitsbergen Current [WSC]) and is the major oceanic heat source to the Arctic Ocean. Along the north‐western ...
    • Autonomous Surface and Underwater Vehicles as Effective Ecosystem Monitoring and Research Platforms in the Arctic—The Glider Project 

      Camus, Lionel; Andrade, Hector; Aniceto, Ana Sofia; Aune, Magnus; Bandara, Kanchana; Basedow, Sünnje Linnéa; Christensen, Kai Håkon; Cook, Jeremy; Daase, Malin; Dunlop, Katherine Mary; Falk-Petersen, Stig; fietzek, Peter; Fonnes, Gro; Ghaffari, Peygham; Gramvik, Geir; Graves, Inger; Hayes, Daniel; Langeland, Tom; Lura, Harald; Marin, Trond Kristiansen; Nøst, Ole Anders; Peddie, David; Pederick, Joel; Pedersen, Geir; Sperrevik, Ann Kristin; Sørensen, Kai; Tassara, Luca; Tjøstheim, Sigurd; Tverberg, Vigdis; Dahle, Salve (Peer reviewed; Journal article, 2021)
      Effective ocean management requires integrated and sustainable ocean observing systems enabling us to map and understand ecosystem properties and the effects of human activities. Autonomous subsurface and surface vehicles, ...
    • Density in sub-arctic zooplankton 

      Falk-Petersen, Stig; Køgeler, J. W.; Kristensen, Åge; Pettersen, Fritz; Dalen, John (ICES CM documents, Working paper, 1985)
      Seasonal variations in specific density were measured for Thysanoessa inermis, Thysanoessa raschii, Meganyctiphanes norvegica, Calanus finmarchicus and Calanus hyperboreus. The density of a 20 mm T. inermis was lowest in ...
    • Fatty acid composition as indicator of food intake in cod larvae (Gadus morhua L.) from Lofoten, northern Norway 

      Tilseth, Snorre; Klungsøyr, Jarle; Falk-Petersen, Stig; Sargent, J.R. (ICES CM Documents;1987/L:31, Working paper, 1987)
      The year class strength of the Arcto-Norwegian cod is mainly determined during the early life stages. The mortality is caused both by starvation and predation which are linked to environmental factors during this period. ...
    • Inverse method applied to autonomous broadband hydroacoustic survey detects higher densities of zooplankton in near-surface aggregations than vessel-based net survey 

      Dunn, Muriel Barbara; Pedersen, Geir; Basedow, Sünnje Linnéa; Daase, Malin; Falk-Petersen, Stig; Bachelot, Loic; Camus, Lionel; Geoffroy, Maxime (Peer reviewed; Journal article, 2022)
      Throughout all oceans, aggregations of zooplankton and ichthyoplankton appear as horizontal sound scattering layers (SSLs) when detected with active acoustic techniques. Quantifying the composition and density of these ...
    • Model-informed classification of broadband acoustic backscatter from zooplankton in an in situ mesocosm 

      Dunn, Muriel Barbara; McGowan-Yallop, Chelsey; Pedersen, Geir; Falk-Petersen, Stig; Daase, Malin Hildegard Elisabeth; Last, Kim; Langbehn, Tom; Fielding, Sophie; Brierley, Andrew S.; Cottier, Finlo Robert; Basedow, Sünnje Linnéa; Camus, Lionel; Geoffroy, Maxime (Peer reviewed; Journal article, 2023)
      Classification of zooplankton to species with broadband echosounder data could increase the taxonomic resolution of acoustic surveys and reduce the dependence on net and trawl samples for ‘ground truthing’. Supervised ...
    • Seasonal ecology in ice-covered Arctic seas - Considerations for spill response decision making 

      Aune, Magnus; Aniceto, Ana Sofia; Biuw, Martin; Daase, Malin; Falk-Petersen, Stig; Leu, Eva; Ottesen, Camilla; Sagerup, Kjetil; Camus, Lionel (Peer reviewed; Journal article, 2018)
      Due to retreating sea ice and predictions of undiscovered oil and gas resources, increased activity in Arctic shelf sea areas associated with shipping and oil and gas exploration is expected. Such activities may accidentally ...
