• Algal hot spots in a changing Arctic Ocean: Sea-ice ridges and the snow-ice interface 

      Fernández-Méndez, Mar; Olsen, Lasse Mork; Kauko, Hanna M.; Meyer, Amelie; Rösel, Anja; Merkouriadi, Ioanna; Mundy, Christopher John; Ehn, Jens K.; Johansson, Malin; Wagner, Penelope Mae; Ervik, Åse; Sorrell, BK; Duarte, Pedro; Wold, Anette; Hop, Haakon; Assmy, Phillipp (Journal article; Peer reviewed, 2018)
      During the N-ICE2015 drift expedition north-west of Svalbard, we observed the establishment and development of algal communities in first-year ice (FYI) ridges and at the snow-ice interface. Despite some indications of ...
    • Black-legged kittiwakes as messengers of Atlantification in the Arctic 

      Vihtakari, Mikko; Welcker, Jorg; Moe, Børge; Chastel, Olivier; Tartu, Sabrina; Hop, Haakon; Bech, Claus; Descamps, Sébastien; Gabrielsen, Geir W. (Journal article; Peer reviewed, 2018)
      Climate warming is rapidly altering marine ecosystems towards a more temperate state on the European side of the Arctic. However, this “Atlantification” has rarely been confirmed, as long-term datasets on Arctic marine ...
    • DNA barcoding of the northern Northeast Atlantic skates (Chondrichthyes, Rajiformes), with remarks on the widely distributed starry ray 

      Lynghammar, Arve; Christiansen, Jørgen Schou; Griffiths, Andrew M.; Fevolden, Svein-Erik; Hop, Haakon; Bakken, Torkild (Journal article; Peer reviewed, 2014)
      The skate fauna in the northern Northeast (NE) Atlantic is poorly investigated, and misidentifications are common. Here, ‘DNA barcoding’ was used to analyse 105 specimens of 15 species previously reported from the area to ...
    • Leads in Arctic pack ice enable early phytoplankton blooms below snow-covered sea ice 

      Assmy, Philipp; Fernández-Méndez, Mar; Duarte, Pedro; Meyer, Amelie; Randelhoff, Achim; Mundy, Christopher John; Olsen, Lasse; Kauko, Hanna M.; Bailey, Allison; Chierici, Melissa; Cohen, Lana; Doulgeris, Anthony Paul; Ehn, Jens K.; Fransson, Agneta; Gerland, Sebastian; Hop, Haakon; Hudson, Stephen R.; Hughes, Nick; Itkin, Polona; Johnsen, Geir; King, Jennifer A.; Koch, Boris P.; Koenig, Zoe; Kwasniewski, Slawomir; Laney, Samuel R.; Nikolaus, Marcel; Pavlov, Alexey K.; Polashenski, Christopher M.; Provost, Christine; Rösel, Anja; Sandbu, Marthe; Spreen, Gunnar; Smedsrud, Lars H.; Sundfjord, Arild; Taskjelle, Torbjørn; Tatarek, Agnieszka; Wiktor, Josef; Wagner, Penelope Mae; Wold, Anette; Steen, Harald; Granskog, Mats A. (Journal article; Peer reviewed, 2017)
      The Arctic icescape is rapidly transforming from a thicker multiyear ice cover to a thinner and largely seasonal first-year ice cover with significant consequences for Arctic primary production. One critical challenge is ...
    • Pelagic occurrences of the ice amphipod Apherusa glacialis throughout the Arctic 

      Kunisch, Erin; Bluhm, Bodil; Daase, Malin; Gradinger, Rolf; Hop, Haakon; Melnikov, Igor A.; Øystein, Varpe; Berge, Jørgen (Journal article; Peer reviewed, 2020)
      Apherusa glacialis is a common, sea ice-associated amphipod found throughout the Arctic Ocean and has long been considered permanently associated with the sea ice habitat. However, pelagic occurrences of A. glacialis have ...
    • Sea ice thermohaline dynamics and biogeochemistry in the Arctic Ocean: Empirical and model results 

      Duarte, Pedro; Meyer, Amelie; Olsen, Lasse Mork; Kauko, Hanna Maria; Assmy, Philipp; Rösel, Anja; Itkin, Polona; Hudson, Stephen R.; Granskog, Mats A.; Gerland, Sebastian; Sundfjord, Arild; Steen, Harald; Hop, Haakon; Cohen, Lana; Peterson, Algot Kristoffer; Jeffery, Nicole; Elliott, Scott M.; Hunke, Elizabeth Clare; Turner, Adrian K. (Journal article; Peer reviewed, 2017)
      Large changes in the sea ice regime of the Arctic Ocean have occurred over the last decades justifying the development of models to forecast sea ice physics and biogeochemistry. The main goal of this study is to evaluate ...
