      Temporally (1965–2015) and spatially (55°–70°N) extensive records of total mercury (Hg) in freshwater fish showed consistent declines in boreal and subarctic Fennoscandia. The database contains 54 560 fish entries (n: pike ...
    • Novel terrestrial haul-out behaviour by ringed seals (Pusa hispida) in Svalbard, in association with harbour seals (Phoca vitulina) 

      Lydersen, Christian; Vaquie-Garcia, Jade; Lydersen, Espen; Christensen, Guttorm; Kovacs, Kit M. (Journal article; Peer reviewed, 2017)
      Ringed seals ( Pusa hispida ) are the most ice-associated of all Arctic pinnipeds. In the Svalbard area, this species has always given birth, moulted and rested on sea ice. In addition, much of their food has been comprised ...
    • Spatial and temporal trends of mercury in freshwater fish in Fennoscandia (1965-2015)

      Mercury (Hg) emissions to the atmosphere cause elevated Hg levels in fish, even in many remote regions of the world. Here we present an extensive database of more than 50 000 measurements of Hg in fish, including 2 775 ...
