• Groundwater Flow Through Continuous Permafrost Along Geological Boundary Revealed by Electrical Resistivity Tomography 

      Hornum, Mikkel Toft; Betlem, Peter; Hodson, Andy (Peer reviewed; Journal article, 2021)
      In continuous permafrost regions, pathways for transport of sub-permafrost groundwater to the surface sometimes perforate the frozen ground and result in the formation of a pingo. Explanations offered for the locations of ...
    • Modelling of the gas hydrate potential in Svalbard's fjords 

      Betlem, Peter; Roy, Srikumar; Birchall, Thomas; Hodson, Andrew; Noormets, Riko; Römer, Miriam; Skogseth, Ragnheid; Senger, Kim (Peer reviewed; Journal article, 2021)
      Large amounts of methane are trapped as natural gas hydrate (NGH) in the sediments of the Arctic. Unlike NGH provinces offshore west of Svalbard (Vestnesa Ridge), NGH potential in Svalbard’s fjords and near-shore environment ...
    • Permafrost trapped natural gas in Svalbard, Norway 

      Birchall, Thomas; Jochmann, Malte Michel; Betlem, Peter; Senger, Kim; Hodson, Andrew; Olaussen, Snorre (Peer reviewed; Journal article, 2023)
      Permafrost is widespread in the High Arctic, including the Norwegian archipelago of Svalbard. The uppermost permafrost intervals have been well studied, but the processes at its base and the impacts of the underlying geology ...
    • Sub-permafrost methane seepage from open-system pingos in Svalbard 

      Hodson, Andrew; Nowak, Aga; Hornum, Mikkel Toft; Senger, Kim; Redeker, Kelly Robert; Christiansen, Hanne H; Jessen, Søren; Betlem, Peter; Thornton, Steve F.; Turchyn, Alexandra V.; Olaussen, Snorre; Marca, Alina (Journal article; Peer reviewed, 2020)
      Methane release from beneath lowland permafrost represents an important uncertainty in the Arctic greenhouse gas budget. Our current knowledge is arguably best developed in settings where permafrost is being inundated by ...
