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 ... -
Putative novel hydrogen- and iron-oxidizing sheath-producing Zetaproteobacteria thrive at the Fåvne deep-sea hydrothermal vent field
Hribovšek, Petra; Denny, Emily Maria; Dahle, Håkon; Mall, Achim; Viflot, Thomas Øfstegaard; Boonnawa, Chanakan; Reeves, Eoghan; Steen, Ida Helene; Stokke, Runar (Journal article; Peer reviewed, 2023)Iron-oxidizing Zetaproteobacteria are well known to colonize deep-sea hydrothermal vent fields around the world where iron-rich fluids are discharged into oxic seawater. How inter-field and intra-field differences in ... -
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 ...
