    • Sea ice meiofauna distribution on local to pan-Arctic scales 

      Bluhm, Bodil A.; Hop, Haakon; Vihtakari, Mikko; Gradinger, Rolf; Iken, Katrin; Melnikov, Igor A.; Søreide, Janne E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-29)
      Arctic sea ice provides microhabitats for biota that inhabit the liquid‐filled network of brine channels and the ice–water interface. We used meta‐analysis of 23 published and unpublished datasets comprising 721 ice cores to synthesize the variability in composition and abundance of sea ice meiofauna at spatial scales ranging from within a single ice core to pan‐Arctic and seasonal scales. Two‐thirds ...

    • Seasonal dynamics and life histories of three sympatric species of Pseudocalanus in two Svalbard fjords 

      Ershova, Elizaveta A; Nyeggen, Margot U.; Yurikova, Daria A.; Søreide, Janne E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-10)
      Small copepods are the most diverse and numerous group in high-latitude zooplankton, yet our knowledge of important species remains poor because of the difficulties involved in correct species identification. In this study, we use a molecular method of identification, a species-specific polymerase chain reaction, to provide the first description of the seasonal dynamics and life histories of the ...

    • Seasonal riverine inputs may affect diet and mercury bioaccumulation in Arctic coastal zooplankton 

      Carrasco, Nathalie; Mcgovern, Maeve; Evenset, Anita; Søreide, Janne E.; Arts, Michael T.; Jonsson, Sofi; Poste, Amanda Elizabeth (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-10-06)
      Climate change driven increases in permafrost thaw and terrestrial runoff are expected to facilitate the mobilization and transport of mercury (Hg) from catchment soils to coastal areas in the Arctic, potentially increasing Hg exposure of marine food webs. The main aim of this study was to determine the impacts of seasonal riverine inputs on land-ocean Hg transport, zooplankton diet and Hg bioaccumulation ...

    • Seasonal variability in non-consumptive mortality of Arctic zooplankton 

      Daase, Malin; Søreide, Janne E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-04)
      Recent observations from high-latitude marine ecosystems indicate that non-consumptive mortality may be particularly high in Arctic zooplankton during the polar night. Here we have estimated the contribution of dead organisms to the mesozooplankton community in the high Arctic (Svalbard 78–81oN) during the polar night (January), in spring (May) and in late summer (end of August). To identify in situ ...

    • Spatio-Temporal Variability of Suspended Particulate Matter in a High-Arctic Estuary (Adventfjorden, Svalbard) Using Sentinel-2 Time-Series 

      Walch, Daniela M. R.; Singh, Rakesh K.; Søreide, Janne E.; Lantuit, Hugues; Poste, Amanda (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-29)
      Arctic coasts, which feature land-ocean transport of freshwater, sediments, and other terrestrial material, are impacted by climate change, including increased temperatures, melting glaciers, changes in precipitation and runoff. These trends are assumed to affect productivity in fjordic estuaries. However, the spatial extent and temporal variation of the freshwater-driven darkening of fjords remain ...
