    • Experimental Assessment of the Environmental Impact of Ethanolamine 

      Buvik, Vanja; Strimbeck, Richard; Knuutila, Hanna K (Chapter, 2021)
      The environmental impact of ethanolamine, a common amine for carbon dioxide capture, was experimentally investigated in laboratory scale microcosms. By exposing the plant-soil systems to varying amounts of ethanolamine, ...
    • Life and Light at the Dead of Night 

      Berge, Jørgen; Johnsen, Geir (Chapter, 2020)
      The Polar Nigth as a unique beauty. The aurora borealis, the moonlight, the faint glow of the sun behind white mountains, and, not the least, the mysteries of the living creatures that we have found in the Polar Night – ...
    • Light in the Polar Night 

      Cohen, Jonathan H.; Berge, Jørgen; Moline, Mark A.; Johnsen, Geir; Zolich, Artur Piotr (Chapter, 2020)
      How much light isa vailable for biological processes during Polar Night? This question appears simple enough. But the reality is that conventional light sen- sors for measuring visible light (~350 to ~700 nm) have not been ...
    • Marine Micro- and Macroalgae in the Polar Night 

      Johnsen, Geir; Leu, Eva; Gradinger, Rolf (Chapter, 2020)
      Microalgae have unique adaptions including low metabolic activity, utilization of lipid storage, and resting stage formation to survive the Polar Night. Some species are mixotrophic or heterotrophic and do survive periods ...
    • Operative Habitat Mapping and Monitoring in the Polar Night 

      Johnsen, Geir; Mogstad, Aksel Alstad; Berge, Jørgen; Cohen, Jonathan H. (Chapter, 2020)
      The Polar Night has long been regarded as a period of no biological activity. As a logical consequence, environmental management has mainly been neglected in this period. We will use the Northguider accident in December ...
    • Portable Catamaran Drone - an uncrewed sampling vehicle for micro-plastics and aquaculture research 

      Zolich, Artur Piotr; Faltynkova, Andrea; Johnsen, Geir; Johansen, Tor Arne (Chapter, 2022)
      In this paper, we present a Portable Catamaran Drone (PCD) - an Uncrewed Surface Vehicle (USV) that may significantly improve the scalability of surface water particle sampling using a plankton net. We preset vehicle design ...
    • Solutions to plastic pollution: A conceptual framework to tackle a wicked problem 

      Wagner, Martin (Chapter, 2021)
      There is a broad willingness to act on global plastic pollution as well as a plethora of available technological, governance, and societal solutions. However, this solution space has not been organized in a larger conceptual ...
