    • Compositional differences in dissolved organic matter between Arctic cold seeps versus non-seep sites at the Svalbard continental margin and the Barents sea 

      Sert, Muhammed Fatih; D’Andrilli, Juliana; Gründger, Friederike; Niemann, Helge; Granskog, Mats; Pavlov, Alexey K.; Ferré, Benedicte; Silyakova, Anna (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-07)
      Dissociating gas hydrates, submerged permafrost, and gas bearing sediments release methane to the water column from a multitude of seeps in the Arctic Ocean. The seeping methane dissolves and supports the growth of aerobic methane oxidizing bacteria (MOB), but the effect of seepage and seep related biogeochemical processes on water column dissolved organic matter (DOM) dynamics is not well ...

    • Marine CDOM accumulation during a coastal Arctic mesocosm experiment: No response to elevated pCO2 levels 

      Pavlov, Alexey K.; Silyakova, Anna; Granskog, Mats A.; Bellerby, Richard; Engel, Anja; Schulz, Kai G.; Brussaard, Corina P. D. (Journal article; Tidsskriftartikkel; Peer reviewed, 2014-05-22)
      A large-scale multidisciplinary mesocosm experiment in an Arctic fjord (Kongsfjorden, Svalbard; 78°56.2′N) was used to study Arctic marine food webs and biogeochemical elements cycling at natural and elevated future carbon dioxide (CO2) levels. At the start of the experiment, marine-derived chromophoric dissolved organic matter (CDOM) dominated the CDOM pool. Thus, this experiment constituted a ...
