Description: Title Marine biodiversity from south coast of Sagres (South of Portugal-Algarve): identification and characterization of biotopes Alternate title PT000012 Date 2012-02-10T18:21:00 Date type Creation: Date identifies when the resource was brought into existence Edition 2012 Presentation form Digital map: Map represented in raster or vector form Abstract Under the MeshAtlantic project (2010-2013) the habitat of an area off the south coast of Portugal (Sagres) was classified. The biological data was gathered from surveys carried out during 2012. Stratified sampling by depth and bottom substrate was performed using underwater visual census, Van Veen grab and beam trawl to estimate fauna densities and quadrate method to estimate macroalgae coverage. Additional and significant data was obtained from image analysis of video records collected during Remote Operated Vehicle (ROV) surveys carried out under the UALG/CCMAR programme or from strict cooperation with the NGO OCEANA. Both these surveys began with a previous acoustic mapping of the seabed by means of Side Scan Sonar and Multi-beam, followed by sediment type classification and ground truthing validation using Van Veen grab sampling. Purpose Provide information on the EUNIS Habitat Status Completed: Production of the data has been completed Individual name Pedro Monteiro & Jorge Gonçalves Organisation name University of Algarve (UAlg-FCT)- Centre of Marine Sciences (CCMAR) Data owner: Instituto Español de Oceanografía (IEO)
