    • Modelling persistent methane seepage offshore western Svalbard since early Pleistocene 

      Knies, Jochen; Daszinnies, Matthias Christian; Plaza-Faverola, Andreia; Chand, Shyam; Sylta, Øyvind; Bünz, Stefan; Johnson, Joel E; Mattingsdal, Rune; Mienert, Jurgen (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-01-31)
      Recent observations of extensive methane release into the oceans and atmosphere have raised concern as to whether rising temperatures across the Arctic could drive rapid destabilization of gas hydrate reservoirs. Here, we report modelling results from hydrate-modulated methane seepage from Vestnesa Ridge, offshore western Svalbard, suggesting that continuous leakage has occurred from the seafloor ...

    • The Plio-Pleistocene seepage history off western Svalbard inferred from 3D petroleum systems modelling 

      Daszinnies, Matthias Christian; Plaza-Faverola, Andreia; Sylta, Øyvind; Bünz, Stefan; Mattingsdal, Rune; Tømmerås, Are; Knies, Jochen (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-05)
      Methane seepage off the coast of Svalbard is demonstrated by active gas flares in the water column today and through precipitation of methane-derived authigenic carbonates (MDAC) over the past 160 000 years. Though submarine discharge of thermogenic methane is well documented, the geological history of past leakage is still debated, largely due to unconstrained free gas sources and seepage trigger ...
