Geometry Type: esriGeometryPolygon

Description: As part of the Canada's commitment to the identification and protection of sensitive benthic marine ecosystems, maps of the location of significant concentrations of corals and sponges on the east coast of Canada were produced through quantitative analyses of research vessel trawl survey data, supplemented with other data sources where available. The taxa analyzed are sponges (Porifera), large and small gorgonian corals (Alcyonacea), and sea pens (Pennatulacea). However, only the sponges (Porifera) and sea pens (Pennatulacea) have been considered in the analysis concerning the Gulf of St. Lawrence biogeographic unit.This data layer only present the results for sponges. #Fra Dans la foulée de l’engagement du Canada visant l’identification et la protection des habitats benthiques vulnérables, des cartes de l’emplacement des concentrations importantes de coraux et d’éponges sur la côte est du Canada ont été produites au moyen d’analyses quantitatives des données des relevés au chalut effectués sur un navire scientifique ainsi que d’autres sources de données lorsque cela était possible. Les taxons analysés sont les éponges (Porifera), les grandes et petites gorgones (Alcyonacea) et les pennatules (Pennatulacea). Par contre, seules les éponges (Porifera) et les plumes de mer (Pennatulacea) sont considérées dans l’analyse concernant la bioregion du golfe Saint-Laurent. Cette couche ne présente que les résutats pour les éponges.
