    • Algal colonization of young arctic sea ice in spring 

      Kauko, Hanna Maria; Olsen, Lasse Mork; Duarte, Pedro; Peeken, Ilka; Granskog, Mats A.; Johnsen, Geir; Fernández-Méndez, Mar; Pavlov, Alexey; Mundy, Christopher John; Assmy, Philipp (Journal article; Peer reviewed, 2018)
      The importance of newly formed sea ice in spring is likely to increase with formation of leads in a more dynamic Arctic icescape. We followed the ice algal species succession in young ice (≤ 0.27 m) in spring at high ...

    • Light response and acclimation of microalgae in a changing Arctic 

      Kauko, Hanna Maria (Doctoral theses at NTNU;2018:270, Doctoral thesis, 2018)
      Summary of thesis: This thesis investigates ice-associated and under-ice algal communities, and the controlling role of light in the Arctic pack ice region. Changes in the light regime are a consequence of the substantial ...

    • 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 ...

    • Wind-driven upwelling of iron sustains dense blooms and food webs in the eastern Weddell Gyre 

      Moreau, Sebastian; Hattermann, Tore; de Steur, Laura; Kauko, Hanna Maria; Ahonen, Heidi; Ardelan, Murat van; Assmy, Philipp; Chierici, Melissa; Descamps, Sebastien; Dinter, Tilman; Falkenhaug, Tone; Fransson, Agneta; Grønningsæter, Eirik; Hallfredsson, Elvar Halldor; Huhn, Oliver; Lebrun, Anais; Lowther, Andrew; Lübcker, Nico; Monteiro, Pedro; Peeken, Ilka; Roychoudhury, Alakendra; Różańska, Magdalena; Ryan-Keogh, Thomas; Sanchez Puerto, Nicolas; Singh, Asmita; Simonsen, Jan Henrik; Steiger, Nadine; Thomalla, Sandy J.; van Tonder, Andre; Wiktor, Josef M; Steen, Harald (Peer reviewed; Journal article, 2023)
      The Southern Ocean is a major sink of anthropogenic CO2 and an important foraging area for top trophic level consumers. However, iron limitation sets an upper limit to primary productivity. Here we report on a considerably ...
