• Comparison between "underway" and "on station" acoustic measurements made during bottom trawl surveys 

      Nicolas, Bez; Mireille, Bouleau; Godø, Olav Rune; Armstrong, Mike; Gerritsen, Hans D.; Vérin, Yves; Massé, Jacques; Méhault, Sonia (ICES CM Documents;2002/J:3, Working paper, 2002)
      It becomes in many cases, routine, to collect acoustic data during bottom trawl surveys, both during and between trawls providing “on station” and “underway” acoustic data. Still, the combination of trawl and acoustic data ...
    • Differences between near bottom biomass spatial structure observed in the Irish Sea, the North Sea and the Barents Sea in recent years 

      Mireille, Bouleau; Nicolas, Bez; Hjellvik, Vidar; Godø, Olav Rune; Reid, David; Beare, Douglas; Greig, Tony; Armstrong, Mike; Gerritsen, Hans D.; Mackinson, Steven; Neville, Suzanna; Kooij, Jeroen van der; Vérin, Yves; Massé, Jacques (ICES CM documents, Working paper, 2003)
      Based on acoustic data and trawl catches collected during bottom trawl surveys, we compare the spatial structure of the biomass available in the first meters above the bottom in three different regions, the Barents Sea ...
    • Testing various geostatistical models to combine bottom trawl catches and acoustic data 

      Bouleau, Mireille; Bez, Nicholas; Reid, David; Godø, Olav Rune; Gerritsen, Hans D. (ICES CM Documents;2004/R:28, Working paper, 2004)
      The aim of the CATEFA project is to combine information on demersal fish stock abundance from acoustic and bottom trawl surveys. While acoustic data are collected continuously while the research ship is underway, it is ...
