• Comparison of Northeast Atlantic mackerel (Scomber scombrus) distribution patterns in the Norwegian Sea using lidar, sonar, and trawl 

      Tenningen, Eirik; Godø, Olav Rune; Iversen, Svein A.; Slotte, Aril; Hjellvik, Vidar; Torkelsen, Terje (ICES CM documents, Working paper, 2003)
      In July 2002 the Institute of Marine Research (IMR), Bergen mapped the distribution and density of mackerel in the Norwegian Sea using lidar, sonar and trawl. A major objective was to test the efficiency of the lidar as ...
    • Detecting Atlantic herring by parametric sonar 

      Godø, Olav Rune; Foote, Kenneth G.; Dybedal, Johnny; Tenningen, Eirik; Patel, Ruben (Journal article; Peer reviewed, 2010-03-17)
      The difference-frequency band of the Kongsberg TOPAS PS18 parametric sub-bottom profiling sonar, nominally 1–6 kHz, is being used to observe Atlantic herring. Representative TOPAS echograms of herring layers and schools ...
    • First Test Results from the New Norwegian Lidar for Monitoring of Marine Resources 

      Tenningen, Eirik (ICES CM Documents;2004/R:42, Working paper, 2004)
      Following promising lidar test flights in 2002, Institute of Marine Research (IMR), Bergen in cooperation with NTNU University, Trondheim started the process of designing and building a new lidar to be ready by summer ...
    • Lidar TS measurements on Northeast Atlantic mackerel (Scomber scombrus) 

      Tenningen, Eirik; Churnside, James H.; Slotte, Aril (ICES CM documents, Working paper, 2003)
      A green linearly polarized laser and a digital video camera were used to find the average reflectivity and lidar target strength of live mackerel. The light reflected from the fish was compared to that reflected from a ...
