    • 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; Tidsskriftartikkel; Peer reviewed, 2022-04-20)
      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 neutrally buoyant plume layer. Considering the number and extent of actively venting hydrothermal sites in the oceans, their contribution to the oceanic DOM pool may be substantial. ...

    • 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; Tidsskriftartikkel; Peer reviewed, 2022-10-31)
      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 rift-valley floor, but deep-tow camera and sidescan surveys reveal the site to be ≥100 m across—unusually large for a volcanically hosted vent on a slow-spreading ridge and more ...
