    • Air-Sea Interaction in Biophysical Modeling: With focus on Northeast Arctic Cod 

      Strand, Kjersti Opstad (Doctoral thesis, 2019-02-15)
      The focus of this thesis is on upper ocean dynamics and the interactions between the atmosphere and the oceans in relation to early life stages of Northeast Arctic cod. The main spawning sites of Northeast Arctic cod are ...

    • Long-Term Statistics of Observed Bubble Depth Versus Modeled Wave Dissipation 

      Strand, Kjersti Opstad; Breivik, Øyvind; Pedersen, Geir; Vikebø, Frode Bendiksen; Sundby, Svein; Christensen, Kai Håkon (Journal article; Peer reviewed, 2020)
      Air bubble penetration depths are investigated with a bottom‐mounted echosounder at a seabed observatory in northern Norway. We compare a 1‐year time series of observed bubble depth against modeled and estimated turbulent ...

    • The Northeast Greenland shelf as a potential habitat for the Northeast Arctic cod 

      Strand, Kjersti Opstad; Sundby, Svein; Albretsen, Jon; Vikebø, Frode Bendiksen (Peer reviewed; Journal article, 2017-09-26)
      Observations (1978–1991) of distributions of pelagic juvenile Northeast Arctic cod (Gadus morhua L.) show that up to 1/3 of the year class are dispersed off the continental shelf and into the deep Norwegian Sea while on ...

    • On the seasonal signal of the Filchner overflow, Weddell Sea, Antarctica 

      Darelius, Elin Maria K.; Strand, Kjersti Opstad; Østerhus, Svein; Gammelsrød, Tor; Årthun, Marius; Fer, Ilker (Peer reviewed; Journal article, 2014)
      The cold ice shelf water (ISW) that formed below the Filchner–Ronne Ice Shelf in the southwestern Weddell Sea, Antarctica, escapes the ice shelf cavity through the Filchner Depression and spills over its sill at a rate of ...

    • Sub-surface maxima in buoyant fish eggs indicate vertical velocity shear and spatially limited spawning grounds 

      Strand, Kjersti Opstad; Vikebø, Frode; Sundby, Svein; Sperrevik, Ann Kristin (Peer reviewed; Journal article, 2018)
      Observed vertical profiles of buoyant particles, in this case pelagic Northeast Arctic cod eggs, occasionally deviate from the vertical diffusion-buoyancy balance by displaying sub-surface maxima. Here we present a mechanism ...

    • Subsurface maxima in buoyant fish eggs indicate vertical velocity shearand spatially limited spawning grounds 

      Strand, Kjersti Opstad; Vikebø, Frode Bendiksen; Sundby, Svein; Sperrevik, Ann Kristin; Breivik, Øyvind (Peer reviewed; Journal article, 2019-05)
      Observed vertical profiles of buoyant particles, in this case pelagic Northeast Arctic (NEA) cod eggs, occasionally deviate from the vertical diffusion‐buoyancy balance by displaying subsurface maxima. Here, we present a ...

    • Variations of the Ice Shelf Water in the southern Weddell Sea, Antarctica 

      Strand, Kjersti Opstad (Master thesis, 2011)
      Ice Shelf Water (ISW) characteristics are investigated using data from moored instruments in the southern Weddell Sea. Most attention is given to the temperature data, but additional current, salinity and oxygen data are ...

    • Wind Intensity Is Key to Phytoplankton Spring Bloom Under Climate Change 

      Vikebø, Frode Bendiksen; Strand, Kjersti Opstad; Sundby, Svein (Peer reviewed; Journal article, 2019-08-30)
      The onset of the spring bloom (OSB) occurs when phytoplankton growth exceeds losses and is promoted by a transition from deep convection to a shallow mixing layer concurrent with increasing light intensities in nutrient-enriched ...
