    • International cooperation in the Arctic – 20 year anniversary 

      Hoel, Alf Håkon (Journal article; Peer reviewed, 2011-11-30)

    • Marine mammal hotspots in the Greenland and Barents Seas 

      Hamilton, Charmain Danielle; Lydersen, Christian; Aars, Jon; Biuw, Martin; Boltunov, Andrei; Born, Erik W.; Dietz, Rune; Folkow, Lars; Glazov, Dmitry M.; Haug, Tore; Heide-Jørgensen, Mads-Peter; Kettemer, Lisa Elena; Laidre, Kristin L.; Øien, Nils Inge; Nordøy, Erling Sverre; Rikardsen, Audun H.; Rosing-Asvid, Aqqalu; Semenova, Varvara; Shpak, Olga V.; Sveegaard, Signe; Ugarte, Fernando; Wiig, Øystein; Kovacs, Kit M. (Peer reviewed; Journal article, 2021)
      Environmental change and increasing levels of human activity are threats to marine mammals in the Arctic. Identifying marine mammal hotspots and areas of high species richness are essential to help guide management and ...

    • Niches of marine mammals in the European Arctic 

      MacKenzie, Kirsteen M.; Lydersen, Christian; Haug, Tore; Routti, Heli Anna Irmeli; Aars, Jon; Andvik, Clare Margaret; Borgå, Katrine; Fisk, A.T.; Meier, Sonnich; Biuw, Martin; Lowther, Andrew; Lindstrøm, Ulf Ove; Kovacs, Kit M. (Peer reviewed; Journal article, 2022)
      The Arctic is warming rapidly, with concomitant sea ice losses and ecosystem changes. The animals most vulnerable to Arctic food web changes are long-lived and slow-growing such as marine mammals, which may not be able to ...

    • Ocean temperature oscillations enable reappearance of blue mussels Mytilus edulis in Svalbard after a 1000 year absence 

      Berge, Jørgen; Johnsen, Geir; Nilsen, Frank; Gulliksen, Bjørn; Slagstad, Dag (Journal article; Peer reviewed, 2005-11-21)
      We report the first observations of settled blue mussels Mytilus edulis L. in the high Arctic archipelago of Svalbard for the first time since the Viking Age. A scattered population was discovered at a single site at the ...

    • One mechanism contributing to co-variability of the Atlantic inflow branches to the Arctic 

      Lien, Vidar S.; Vikebø, Frode B.; Skagseth, Øystein (Journal article; Peer reviewed, 2013-02-12)
      The two-branched inflow of warm and saline Atlantic Water to the Arctic is the major contributor of oceanic heat to the Arctic climate system. However, while the Atlantic Water entering the Arctic through the Fram Strait ...

    • A risk assessment review of mercury exposure in Arctic marine and terrestrial mammals 

      Dietz, Rune; Letcher, Robert J.; Aars, Jon; Andersen, Magnus; Boltunov, Andrei; Born, Erik W.; Ciesielski, Tomasz Maciej; Das, Krishna; Dastnai, Sam; Derocher, Andrew E.; Desforges, Jean-Pierre; Eulaers, Igor; Ferguson, Steve; Hallanger, Ingeborg G.; Heide-Jørgensen, Mads P.; Heimbürger-Boavida, Lars-Eric; Hoekstra, Paul F.; Jenssen, Bjørn Munro; Kohler, Stephen Gustav; Larsen, Martin M.; Lindstrøm, Ulf Ove; Lippold, Anna; Morris, Adam; Nabe-Nielsen, Jacob; Nielsen, Nynne H.; Peacock, Elizabeth E.; Pinzone, Marianna; Rigét, Frank F.; Rosing-Asvid, Aqqalu; Routti, Heli Anna Irmeli; Siebert, Ursula; Stenson, Garry; Stern, Gary; Strand, Jakob; Søndergaard, Jens; Treu, Gabriele; Víkingsson, Gisli A.; Wang, Feiyue; Welker, Jeffrey M.; Wiig, Øystein; Wilson, Simon J.; Sonne, Christian (Peer reviewed; Journal article, 2022)
      There has been a considerable number of reports on Hg concentrations in Arctic mammals since the last Arctic Monitoring and Assessment Programme (AMAP) effort to review biological effects of the exposure to mercury (Hg) ...

    • Short-term hydrographic variability in a stratified Arctic fjord 

      Skarðhamar, Jofrid; Svendsen, Harald (Journal article; Peer reviewed, 2010)
      Fjords in the Arctic often have a more complex circulation pattern than the classical two dimentional estuarine circulation. This is due to the effects of the Earth’s rotation on stratified waters in wide fjords. Observations ...

    • The Arctic Ocean in summer: A quasi-synoptic inverse estimate of boundary fluxes and water mass transformation 

      Tsubouchi, T.; Bacon, S.; Garabato, A.C. Naveira; Aksenov, Y.; Laxon, S.W.; Fahrbach, E.; Beszczynska-Möller, A.; Hansen, E.; Lee, Craig M.; Ingvaldsen, Randi (Journal article; Peer reviewed, 2012-01-31)
      The first quasi-synoptic estimates of Arctic Ocean and sea ice net fluxes of volume, heat and freshwater are calculated by application of an inverse model to data around the ocean boundary. Hydrographic measurements from ...

    • Trans-polar drift-pathways of riverine European microplastic 

      Huserbråten, Mats Brockstedt Olsen; Hattermann, Tore; Broms, Cecilie; Albretsen, Jon (Peer reviewed; Journal article, 2022)
      High concentrations of microplastic particles are reported across the Arctic Ocean–yet no meaningful point sources, suspension timelines, or accumulation areas have been identified. Here we use Lagrangian particle advection ...
