    • Cold Seeps and Coral Reefs in Northern Norway: Carbon Cycling in Marine Ecosystems With Coexisting Features 

      Sert, Muhammed Fatih; Bernstein, Hans Christopher; Dølven, Knut Ola; Petters, Sebastian; Kekäläinen, Timo; Jänis, Janne; Corrales Guerrero, Jorge; Ferré, Benedicte (Journal article; Tidsskriftartikkel; Peer reviewed, 2025-03-20)
      Cold seeps and cold-water corals (CWCs) coexist on Northern Norway's continental shelf at the Hola trough between Lofoten and Vesterålen. Here, cold seeps release methane from the seabed, yet none reaches the sea surface. Instead, the methane dissolves and disperses in the ocean where it is ultimately consumed by methane-oxidizing microorganisms. These microorganisms metabolize methane and release ...
    • Recurrent Lorentzian Weyl Spaces 

      Dikarev, Andrei; Galaev, Anton S.; Schneider, Eivind (Journal article; Tidsskriftartikkel; Peer reviewed, 2024-07-02)
      We find the local form of all non-closed Lorentzian Weyl manifolds (M,c,∇) with recurrent curvature tensor. The recurrent curvature tensor turns out to be weighted parallel, i.e., the obtained spaces provide certain generalization of locally symmetric affine spaces for the Weyl geometry. If the dimension of the manifold is greater than 3, then the conformal structure is flat, and the recurrent Weyl ...
