    • Mineralogical distribution and genetic aspects of cobalt at the active Fåvne and Loki’s Castle seafloor massive sulfide deposits, Arctic Mid-Ocean Ridges 

      Sahlström, Fredrik; Strmic Palinkas, Sabina; Dundas, Siv Hjorth; Sendula, Eszter; Cheng, Yanbo; Wold, Marie; Pedersen, Rolf Birger Svarstad (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-12-16)
      The demand for responsibly sourced cobalt has increased dramatically as a result of the global transition to ‘fossil-free’ electromobility. However, the distribution, mineralogical expressions and mechanisms of concentration of Co in different types of hydrothermal ore deposits remain poorly constrained, inhibiting resource assessments and exploration. Here we report Co and other metal concentrations ...

    • The Volcanic Hazards of Jan Mayen Island (North-Atlantic) 

      Gjerløw, Eirik; Höskuldsson, Ármann; Bartolini, Stefania; Biass, Sebastien; Mossoux, Sophie; Gilbert, Jennie S.; Pedersen, Rolf Birger Svarstad; Marti, Joan (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-04)
      Hazard assessment of remote volcanic islands provides many challenges compared to other volcanoes and volcanic fields. Here we present the first systematic volcanic hazard assessment of Jan Mayen Island, a remote island located in the North-Atlantic Ocean and home to the northernmost active subaerial volcano in the world (Beerenberg Volcano), and we discuss some of the challenges and characteristics ...
