    • Biogeochemical consequences of a changing Arctic shelf seafloor ecosystem 

      März, Christian; Freitas, Felipe; Faust, Johan Christoph; Godbold, Jasmin A.; Tessin, Alyson; Abbott, Geoffrey D.; Airs, Ruth; Arndt, Sandra; Barnes, David K.A.; Grange, Laura; Gray, Neil; Head, Ian M.; Hendry, Katharine R; Hilton, Robert; Reed, Adam J.; Ruhl, Saskia; Solan, Martin; Stevenson, Mark A; Tait, Karen; Ward, James M.; Widdicombe, Stephen; Souster, Terri A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-10-09)
      Unprecedented and dramatic transformations are occurring in the Arctic in response to climate change, but academic, public, and political discourse has disproportionately focussed on the most visible and direct aspects of change, including sea ice melt, permafrost thaw, the fate of charismatic megafauna, and the expansion of fisheries. Such narratives disregard the importance of less visible and ...

    • Response of Methanogens in Arctic Sediments to Temperature and Methanogenic Substrate Availability 

      Blake, Lynsay; Tveit, Alexander Tøsdal; Øvreås, Lise; Head, Ian M.; Gray, Neil (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-06-17)
      Although cold environments are major contributors to global biogeochemical cycles, comparatively little is known about their microbial community function, structure, and limits of activity. In this study a microcosm based approach was used to investigate the effects of temperature, and methanogenic substrate amendment, (acetate, methanol and H2/CO2) on methanogen activity and methanogen community ...
