    • The rise and decline of fishing industry support – with a translation from Norwegian of Bjørn S. Brochmann's 1981 article ‘long-term effects of government support to the fisheries’ 

      Flaaten, Ola (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-21)
      Input and output measures, including the use of (Pigou) taxes, have been recommended to bridge the gap between average and marginal revenues in fisheries. Several countries have improved management, but few have followed the fiscal recommendations. On the contrary, subsidies that can expand capacity and effort have been and still are used. For decades, international organizations such as the WTO, ...

    • Seasonal shifts of microbial methane oxidation in Arctic shelf waters above gas seeps 

      Gründger, Friederike; Probandt, David; Knittel, Katrin; Carrier, Vincent; Kalenitchenko, Dimitri; Silyakova, Anna; Serov, Pavel; Ferré, Benedicte; Svenning, Mette Marianne; Niemann, Helge (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-07)
      The Arctic Ocean subseabed holds vast reservoirs of the potent greenhouse gas methane (CH<sub>4</sub>), often seeping into the ocean water column. In a continuously warming ocean as a result of climate change an increase of CH<sub>4</sub> seepage from the seabed is hypothesized. Today, CH<sub>4</sub> is largely retained in the water column due to the activity of methane-oxidizing bacteria (MOB) that ...
