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 ... -
Numerical modelling of permafrost spring discharge and open-system pingo formation induced by basal permafrost aggradation
Hornum, Mikkel Toft; Hodson, Andrew; Jessen, Søren; Bense, Victor; Senger, Kim (Journal article; Peer reviewed, 2020)In the high Arctic valley of Adventdalen, Svalbard, sub-permafrost groundwater feeds several pingo springs distributed along the valley axis. The driving mechanism for groundwater discharge and associated pingo formation ... -
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 ...
