ABSTRACT <\/span><\/p> Vandermeulen, H. 2013. Mapping eelgrass (<\/span>Zostera marina<\/span>) with a novel towfish: Richibucto and Shippagan, New Brunswick. Can. Tech. Rep. Fish. Aquat. Sci. 3064: v + 19 p. <\/span><\/p> A towfish containing sidescan and video hardware was used to map eelgrass in two shallow northern New Brunswick estuaries. The sidescan and video data were useful in documenting suspected impacts of oyster aquaculture gear and eutrophication on eelgrass. With one boat and a crew of three, the mapping was accomplished at a rate of almost 10 km2 per day. That rate far exceeds what could be accomplished by a SCUBA based survey with the same crew. Moreover, the towfish survey applied with a complementary echosounder survey is potentially a more cost effective mapping method than satellite based remote sensing. <\/span><\/p> RÉSUMÉ <\/span><\/p> Vandermeulen, H. 2013. Vandermeulen, H. 2013. Cartographie des zostères (Zostera marina) à l'aide d'un nouveau poisson : Richibucto et Shippagan, Nouveau-Brunswick. Can. Tech. Rep. Fish. Aquat. Sci. 3064: v + 19 p. <\/span><\/p> On utilise un poisson muni d'équipement vidéo et de balayage latéral afin de cartographier les zostères dans deux estuaires peu profonds au nord du Nouveau-Brunswick. Les données recueillies par l'équipement vidéo et de balayage latéral ont servi à documenter l'effet soupçonné des engins d'ostréiculture et de l'eutrophisation sur les zostères. La cartographie a été effectuée à un rythme de près de 10 km2 par jour à bord d'une embarcation comptant trois équipiers. Ce rythme est fort supérieur à celui que l'on obtiendrait en réalisant un relevé en plongée avec le même équipage. De plus, une méthode de cartographie qui combine le relevé par poisson avec le relevé par échosondeur pourrait s'avérer moins coûteuse que la télémesure par satellite. <\/span><\/p> <\/p> Learn more or download this dataset from the Government of Canada's Open data portal.<\/span><\/a><\/p> <\/p> Apprenez-en plus ou téléchargez cet ensemble de données à partir du portail de données ouvertes du gouvernement du Canada.<\/span><\/a><\/p> <\/p><\/div><\/div><\/div>",
