    • Biogeochemical evidence of anaerobic methane oxidation on active submarine mud volcanoes on the continental slope of the Canadian Beaufort Sea 

      Lee, Dong-Hun; Kim, Jung-Hyun; Lee, Yung Mi; Stadnitskaia, Alina; Jin, Young Keun; Niemann, Helge; Kim, Young-Gyun; Shin, Kyung-Hoon (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-20)
      In this study, we report lipid biomarker patterns and phylogenetic identities of key microbial communities mediating anaerobic oxidation of methane (AOM) in active mud volcanoes (MVs) on the continental slope of the Canadian Beaufort Sea. The carbon isotopic compositions (δ13C) of sn-2- and sn-3-hydroxyarchaeol showed the highly 13C-depleted values (−114 ‰ to −82 ‰) associated with a steep depletion ...

    • Life on the edge: Active microbial communities in the Kryos MgCl2-brine basin at very low water activity 

      Steinle, Lea; Knittel, Katrin; Felber, Nicole; Casalino, Claudia; de Lange, Gert; Tessarolo, Chiara; Stadnitskaia, Alina; Sinninghe Damsté, Jaap S.; Zopfi, Jakob; Lehmann, Moritz F.; Treude, Tina (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-04-17)
      The Kryos Basin is a deep-sea hypersaline anoxic basin (DHAB) located in the Eastern Mediterranean Sea (34.98°N 22.04°E). It is filled with brine of re-dissolved Messinian evaporites and is nearly saturated with MgCl<sub>2</sub>-equivalents, which makes this habitat extremely challenging for life. The strong density difference between the anoxic brine and the overlying oxic Mediterranean seawater ...
