    • Assessing net primary production in the northwestern Barents Sea using in situ, remote sensing and modelling approaches 

      Castro de la Guardia, Laura; Hernández Fariñas, Tania; Marchese, Christian; Amargant I Arumi, Marti; Myers, Paul G.; Bélanger, Simon; Assmy, Philipp Kurt Wolf; Gradinger, Rolf Rudolf; Duarte, Pedro (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-24)
      The northwestern Barents Sea (NW-BS) is a highly productive region within the transitional zones of an Atlantic to Arctic-dominated marine ecosystem. The steep latitudinal gradients in sea ice concentration, Atlantic and Arctic Water, offer an opportunity to test hypotheses on physical drivers of spatial and temporal variability of net primary production (NPP). However, quantifying NPP in such a ...

    • Interannual differences in sea ice regime in the north-western Barents Sea cause major changes in summer pelagic production and export mechanisms 

      Amargant I Arumi, Marti; Müller, Oliver; Bodur, Yasemin Vicdan; Ntinou, Iliana Vasiliki; Vonnahme, Tobias; Assmy, Philipp Kurt Wolf; Kohlbach, Doreen; Chierici, Melissa; Jones, Elizabeth Marie; Olsen, Lasse Mork; Tsagaraki, Tatiana; Reigstad, Marit; Bratbak, Gunnar; Gradinger, Rolf Rudolf (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-22)
      The Barents Sea is a highly dynamic and productive marine ecosystem and a hotspot of global warming. Variability in sea ice extent is a common feature in the Barents Sea with substantial movements of the sea ice edge on short-term, seasonal to interannual time scales. Historically the northern Barents Sea (north of 75◦N) has been ice-covered in winter, but recently it has become the area with most ...

    • Seasonal patterns of vertical flux in the northwestern Barents Sea under Atlantic Water influence and sea-ice decline 

      Bodur, Yasemin Vicdan; Renaud, Paul Eric; Goraguer, Lucie Hélène Marie; Amargant I Arumi, Marti; Assmy, Philipp Kurt Wolf; Dabrowska, Anna Maria; Marquardt, Miriam; Renner, Angelika; Tatarek, Agnieska; Reigstad, Marit (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-27)
      The northern Barents Sea is a productive Arctic inflow shelf with a seasonal ice cover and as such, a location with an efficient downward export of particulate organic matter through the biological carbon pump. The region is under strong influence of Atlantification and sea-ice decline, resulting in a longer open water and summer period. In order to understand how these processes influence the ...
