    • An Arctic natural oil seep investigated from space to the seafloor 

      Panieri, Giuliana; Argentino, Claudio; Ramalho, Sofia P.; Vulcano, Francesca; Savini, Alessandra; Fallati, Luca; Brekke, Trond; Galimberti, Giulia; Riva, Federica; Balsa, João; Eilertsen, Mari Heggernes; Stokke, Runar; Steen, Ida Helene; Sahy, Diana; Kalenitchenko, Dimitri Stanislas Desire; Bünz, Stefan; Mattingsdal, Rune (Journal article; Peer reviewed, 2023)
      Due to climate change, decreasing ice cover and increasing industrial activities, Arctic marine ecosystems are expected to face higher levels of anthropogenic stress. To sustain healthy and productive ocean ecosystems, it ...

    • A chemosynthetic weed: the tubeworm Sclerolinum contortum is a bipolar, cosmopolitan species 

      Georgieva, Magdalena N.; Wiklund, Helena; Bell, James B; Eilertsen, Mari Heggernes; Mills, Rachel A; Little, Crispin T S; Glover, Adrian G. (Peer reviewed; Journal article, 2015-12-14)
      Background Sclerolinum (Annelida: Siboglinidae) is a genus of small, wiry deep-sea tubeworms that depend on an endosymbiosis with chemosynthetic bacteria for their nutrition, notable for their ability to colonise a multitude ...

    • Do ampharetids take sedimented steps between vents and seeps? Phylogeny and habitat-use of Ampharetidae (Annelida, Terebelliformia) in chemosynthesis-based ecosystems 

      Eilertsen, Mari Heggernes; Kongsrud, Jon Anders; Alvestad, Tom; Stiller, Josefin; Rouse, Greg W; Rapp, Hans Tore (Peer reviewed; Journal article, 2017-10-31)
      Background: A range of higher animal taxa are shared across various chemosynthesis-based ecosystems (CBEs), which demonstrates the evolutionary link between these habitats, but on a global scale the number of species ...

    • Evolutionary history, connectivity and habitat-use of annelids from deep-sea chemosynthesis-based ecosystems, with an emphasis on the Arctic mid-Ocean Ridge and the Nordic Seas 

      Eilertsen, Mari Heggernes (Doctoral thesis, 2018-03-16)
      The enigmatic fauna of chemosynthesis-based ecosystems (CBEs), i.e. hydrothermal vents, cold seeps and organic falls, has been the subject of intensive research over the last decades. However, there are still many aspects ...

    • Genetic connectivity from the Arctic to the Antarctic: Sclerolinum contortum and Nicomache lokii (Annelida) are both widespread in reducing environments 

      Eilertsen, Mari Heggernes; Georgieva, Magdalena N.; Kongsrud, Jon Anders; Linse, Katrin; Wiklund, Helena; Glover, Adrian G.; Rapp, Hans Tore (Peer reviewed; Journal article, 2018-03-19)
      The paradigm of large geographic ranges in the deep sea has been challenged by genetic studies, which often reveal putatively widespread species to be several taxa with more restricted ranges. Recently, a phylogeographic ...

    • Hot Vents Beneath an Icy Ocean: The Aurora Vent Field, Gakkel Ridge, Revealed 

      Ramirez-Llodra, Eva; Argentino, Claudio; Baker, Maria; Boetius, Antje; Costa, Carolina; Dahle, Håkon; Denny, Emily Maria; Dessandier, Pierre-Antoine; Eilertsen, Mari Heggernes; Ferré, Benedicte; German, Cristopher R.; Hand, Kevin; Hilário, Ana; Hislop, Lawrence; Jamieson, John W.; Kalenitchenko, Dimitri; Mall, Achim; Panieri, Giuliana; Purser, Autun; Ramalho, Sofia P.; Reeves, Eoghan; Rolley, Leighton; Pereira, Samuel; de Azevedo Ribeiro, Pedro Miguel; Sert, Muhammed Fatih; Steen, Ida Helene; Stetzler, Marie Helene Paula; Stokke, Runar; Victorero, Lissette; Vulcano, Francesca; Vågenes, Stig; Waghorn, Kate Alyse; Bünz, Stefan (Journal article; Peer reviewed, 2022)
      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. ...

    • A New Species of Osedax (Siboglinidae: Annelida) From Colonization Experiments in the Arctic Deep Sea 

      Eilertsen, Mari Heggernes; Dahlgren, Thomas Gunnar; Rapp, Hans Tore (Journal article; Peer reviewed, 2020)
      Large parcels of organic matter in the deep sea, such as whale carcasses, harbor a very specialized fauna, most famously the bone-eating worms in the genus Osedax (Annelida, Siboglinidae). Although Osedax was first described ...
