Acoustic data collected during and between bottom trawl stations: consistency and common trends
Bez, Nicholas; Reid, David; Neville, Suzanna; Vérin, Yves; Hjellvik, Vidar; Gerritsen, Hans D. (Journal article; Peer reviewed, 2007)Acoustic data are often collected during bottom trawl surveys. Their use can potentially improve the precision and accuracy of fish abundance estimates if acoustic data collected between trawl stations are consistent with ... -
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 ...
