    • Borealization of the Arctic Ocean in response to anomalous advection from sub-Arctic seas. 

      Polyakov, Igor V.; Alkire, Mattew; Bluhm, Bodil; Brown, Kristina; Carmack, Eddy C.; Chierici, Melissa; Danielson, Seth L.; Ellingsen, Ingrid H.; Ershova, Elizaveta; Gardfeldt, Katrin; Ingvaldsen, Randi Brunvær; Pnyushkov, Andrey V.; Slagstad, Dag; Wassmann, Paul (Peer reviewed; Journal article, 2020)
      An important yet still not well documented aspect of recent changes in the Arctic Ocean is associated with the advection of anomalous sub-Arctic Atlantic- and Pacific-origin waters and biota into the polar basins, a process ...

    • The Influence of Sea Ice Cover and Atlantic Water Advection on Annual Particle Export North of Svalbard 

      Dybwad, Christine Schumann; Lalande, Catherine; Bodur, Yasemin V.; Henley, Sean; Cottier, Finlo Robert; Ershova, Elizaveta; Hobbs, Laura; Last, Kim S.; Dabrowska, Anna Maria; Reigstad, Marit (Peer reviewed; Journal article, 2022)
      The Arctic Ocean north of Svalbard has recently experienced large sea ice losses and the increasing prominence of Atlantic water (AW) advection. To investigate the impact of these ongoing changes on annual particle export, ...

    • Meroplankton Diversity, Seasonality and Life-History Traits Across the Barents Sea Polar Front Revealed by High-Throughput DNA Barcoding 

      Descoteaux, Raphaelle; Ershova, Elizaveta; Wangensteen, Owen S.; Præbel, Kim; Renaud, Paul Eric; Cottier, Finlo Robert; Bluhm, Bodil (Peer reviewed; Journal article, 2021)
      In many species of marine benthic invertebrates, a planktonic larval phase plays a critical role in dispersal. Very little is known about the larval biology of most species, however, in part because species identification ...

    • Mock samples resolve biases in diversity estimates and quantitative interpretation of zooplankton metabarcoding data 

      Ershova, Elizaveta; Wangensteen, Owen S.; Falkenhaug, Tone (Peer reviewed; Journal article, 2023)
      Metabarcoding is a rapidly developing tool in marine zooplankton ecology, although most zooplankton surveys continue to rely on visual identification for monitoring purposes. We attempted to resolve some of the biases ...

    • North Sea Ecosystem Cruise Report_JH2022206 

      Franzè, Gayantonia; Falkenhaug, Tone; Albretsen, Jon; Ershova, Elizaveta; Gundersen, Kjell; Heldal, Hilde Elise; Lerch, Sarah (Toktrapport;2023 - 2, Research report, 2023)
      The North Sea Ecosystem cruise (NSEC) is a multi-purpose survey established to monitor distribution and interactions of several components that constitute the lower trophic levels of the pelagic food web including ...

    • Origin of marine invertebrate larvae on an Arctic inflow shelf 

      Descoteaux, Raphaelle; Huserbråten, Mats Brockstedt Olsen; Jørgensen, Lis Lindal; Renaud, Paul Eric; Ingvaldsen, Randi Brunvær; Ershova, Elizaveta; Bluhm, Bodil (Peer reviewed; Journal article, 2022)
      Many benthic invertebrate taxa possess planktonic early life stages which drift with water currents and contribute to dispersal of the species, sometimes reaching areas beyond the current ranges of the adults. Until recently, ...

    • Photoperiodism and overwintering in boreal and sub-Arctic Calanus finmarchicus populations 

      Coguiec, Estelle; Last, Kim S.; Cohen, Jonathan H.; Hobbs, Laura; Choquet, Marvin; Ershova, Elizaveta; Berge, Jørgen; Daase, Malin (Journal article, 2023)

    • Seasonal Variability in the Zooplankton Community Structure in a Sub-Arctic Fjord as Revealed by Morphological and Molecular Approaches 

      Coguiec, Estelle; Ershova, Elizaveta; Daase, Malin; Vonnahme, Tobias R.; Wangensteen, Owen S.; Gradinger, Rolf; Præbel, Kim; Berge, Jørgen (Peer reviewed; Journal article, 2021)
      Phyto- and zooplankton in Arctic and sub-Arctic seas show very strong seasonal changes in diversity and biomass. Here we document the seasonal variability in the mesozooplankton community structure in a sub-Arctic fjord ...

    • Thirty years of nutrients and biogeochemistry in the Norwegian, Greenland and Iceland Seas, 1990-2019 

      Gundersen, Kjell; Møgster, Jane S.; Lien, Vidar Surén; Ershova, Elizaveta; Lunde, Linda Fonnes; Arnesen, Hilde; Olsen, Ann-Kristin (Peer reviewed; Journal article, 2023)
      This dataset contains biogeochemical samples analyzed by the Plankton Chemistry Laboratory at the Institute of Marine Research (IMR), from the Norwegian, Greenland and Iceland Seas. Number of surveys and stations have ...
