    • Nitrate supply and uptake in the Atlantic Arctic sea ice zone: seasonal cycle, mechanisms and drivers 

      Henley, Sian F.; Porter, Marie; Hobbs, Laura; Braun, Judith; Guillaume-Castel, Robin; Venables, Emily J.; Dumont, Estelle; Cottier, Finlo Robert (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-31)
      Nutrient supply to the surface ocean is a key factor regulating primary production in the Arctic Ocean under current conditions and with ongoing warming and sea ice losses. Here we present seasonal nitrate concentration and hydrographic data from two oceanographic moorings on the northern Barents shelf between autumn 2017 and summer 2018. The eastern mooring was sea ice-covered to varying degrees ...

    • A Polar Surface Eddy Obscured by Thermal Stratification 

      Porter, Marie; Henley, Sian F.; Orkney, A.; Bouman, H. A.; Hwang, B.; Dumont, E.; Venables, E. J.; Cottier, Finlo Robert (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-12)
      Mesoscale and submesoscale eddies play an important role in the distribution of heat and biogeochemical properties throughout the global oceans. Such eddies are important in the Arctic Ocean, particularly in the frontal regions, but are difficult to detect using traditional satellite‐based methods. Here we use high‐resolution in situ data from an underwater glider to identify a surface eddy that was ...
