    • Effects of climate change on methane emissions from seafloor sediments in the Arctic Ocean: A review 

      James, Rachel; Bousquet, Philippe; Bussmann, Ingeborg; Haeckel, Matthias; Kipfer, Rolf; Leifer, Ira; Niemann, Helge; Ostrovsky, Ilia; Piskozub, Jacek; Rehder, Gregor; Treude, Tina; Vielstadte, Lisa; Greinert, Jens (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-17)
      Large quantities of methane are stored in hydrates and permafrost within shallow marine sediments in the Arctic Ocean. These reservoirs are highly sensitive to climate warming, but the fate of methane released from sediments is uncertain. Here, we review the principal physical and biogeochemical processes that regulate methane fluxes across the seabed, the fate of this methane in the water column, ...

    • Water column methanotrophy controlled by a rapid oceanographic switch 

      Steinle, Lea; Graves, Carolyn A.; Treude, Tina; Ferré, Benedicte; Biastoch, Arne; Bussmann, Ingeborg; Berndt, Christian; Krastel, Sebastian; James, Rachel H.; Behrens, Erik; Böning, Claus W.; Greinert, Jens; Sapart, Célia-Julia; Scheinert, Markus; Sommer, Stefan; Lehmann, Moritz F.; Niemann, Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-20)
      Large amounts of the greenhouse gas methane are released from the seabed to the water column, where it may be consumed by aerobic methanotrophic bacteria. The size and activity of methanotrophic communities, which determine the amount of methane consumed in the water column, are thought to be mainly controlled by nutrient and redox dynamics. Here, we report repeated measurements of methanotrophic ...
