• Microplastic accumulation by tube-dwelling, suspension feeding polychaetes from the sediment surface: A case study from the Norwegian Continental Shelf 

      Knutsen, Heidi; Cyvin, Jakob Bonnevie; Totland, Christian; Wade, Emma Jane; Castro, Veronica; Pettersen, Arne; Laugesen, Jens; Møskeland, Thomas; Arp, Hans Peter; Lilleeng, Øyvind (Peer reviewed; Journal article, 2020)
      Sediment samples (0–1 cm) and tube-dwelling polychaetes from the Norwegian Continental Shelf and the Barents Sea were collected, including areas close to oil and gas installations and remote locations. Microplastics (≥45 μm) ...
    • Snow creep pressure on mast constructions 

      Larsen, Jan Otto; Laugesen, Jens (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 1990)
      In Norway snow-creep quite often causes damage on mast constructions on hillsides exposed to deep snow-cover. An extensive snow-creep measurement program has therefore been carried out for different constructions at NGI's ...
    • Snow-creep pressure on masts 

      Larsen, Jan Otto; Laugesen, Jens; Kristensen, Krister (Journal article, 1989)
      Snow-pressure measurements have been carried out on two masts at the NGI avalanche station in Grasdalen, western Norway. These two tubular masts have diameters of 0.22 and 0.42 m, respectively, and are situated on a 25° ...
