• Abiotic synthesis of methane and organic compounds in Earth’s lithosphere 

      Reeves, Eoghan; Fiebig, Jens (Journal article; Peer reviewed, 2020)
      Accumulation of molecular hydrogen in geologic systems can create conditions energetically favorable to transform inorganic carbon into methane and other organic compounds. Although hydrocarbons with a potentially abiotic ...
    • Compositions of dissolved organic matter in the ice-covered waters above the Aurora hydrothermal vent system, Gakkel Ridge, Arctic Ocean 

      Sert, Muhammed Fatih; Niemann, Helge; Reeves, Eoghan; Granskog, Mats A.; Hand, Kevin P.; Kekäläinen, Timo; Jänis, Janne; Rossel, Pamela; Ferré, Benedicte; Silyakova, Anna; Gründger, Friederike (Journal article; Peer reviewed, 2022)
      Hydrothermal vents modify and displace subsurface dissolved organic matter (DOM) into the ocean. Once in the ocean, this DOM is transported together with elements, particles, dissolved gases and biomass along with the ...
    • Hot Vents Beneath an Icy Ocean: The Aurora Vent Field, Gakkel Ridge, Revealed

      Evidence of hydrothermal venting on the ultra-slow spreading Gakkel Ridge in the Central Arctic Ocean has been available since 2001, with first visual evidence of black smokers on the Aurora Vent Field obtained in 2014. ...
    • Phylogenetic and functional diverse ANME-1 thrive in Arctic hydrothermal vents 

      Vulcano, Francesca; Hahn, Cedric Jasper; Roerdink, Desiree Lisette; Dahle, Håkon; Reeves, Eoghan; Wegener, Gunter; Steen, Ida Helene; Stokke, Runar (Journal article; Peer reviewed, 2022)
      The methane-rich areas, the Loki's Castle vent field and the Jan Mayen vent field at the Arctic Mid Ocean Ridge (AMOR), host abundant niches for anaerobic methane-oxidizers, which are predominantly filled by members of the ...
    • Tailoring Hydrothermal Vent Biodiversity Toward Improved Biodiscovery Using a Novel in situ Enrichment Strategy 

      Stokke, Runar; Reeves, Eoghan; Dahle, Håkon; Fedøy, Anita-Elin; Viflot, Thomas Øfstegaard; Onstad, Solveig L.; Vulcano, Francesca; Pedersen, Rolf Birger; Eijsink, Vincent; Steen, Ida Helene (Journal article; Peer reviewed, 2020)
      Deep-sea hydrothermal vents are amongst the most extreme environments on Earth and represent interesting targets for marine bioprospecting and biodiscovery. The microbial communities in hydrothermal vents are often dominated ...
    • Volcanically hosted venting with indications of ultramafic influence at Aurora hydrothermal field on Gakkel Ridge 

      German, Christopher R.; Reeves, Eoghan; Türke, Andreas; Diehl, Alexander; Albers, Elmar; Bach, Wolfgang; Purser, Autun; Ramalho, Sofia P.; Suman, Stefano; Mertens, Christian; Walter, Maren; Ramirez-Llodra, Eva; Schlindwein, Vera; Bünz, Stefan; Boetius, Antje (Journal article; Peer reviewed, 2022)
      The Aurora hydrothermal system, Arctic Ocean, hosts active submarine venting within an extensive field of relict mineral deposits. Here we show the site is associated with a neovolcanic mound located within the Gakkel Ridge ...
