  • Updated habitat map resulting from an integrated analysis of the 2013 dedicated survey data (collected on cruise CEND0613) for South West Deeps (West) recommended Marine Conservation Zone (rMCZ). A new habitat map for the site was produced by analysing and interpreting the available acoustic data and the ground-truth data collected by the dedicated surveys of South West Deeps West rMCZ. The process is a combination of two approaches, auto-classification (image analysis) and expert interpretation. The routine for auto-classification is flexible and dependent on site-specific data, allowing for application of a bespoke routine to maximise the acoustic data available. ArcGIS was used to perform an initial unsupervised classification on the supplied backscatter image. The single band backscatter mosaic was filtered and smoothed prior to the application of an Iso cluster/maximum likelihood classification routine. For further information, refer to the South-West Deeps (West) rMCZ Post-survey Site Report.

  • SmartDots is a platform that facilitates exchanges and workshops to assess fish age readings and fish maturity. Experts estimate fish age by analyzing otolith pictures, using the SmartDots app. Fish maturity is determined by analysing gonad pictures in the web app. These readings are used to facilitate fish stock assessments.

  • Seabed habitat map (Habitat directive classification system) performed by Andromede Oceanologie within the framework of CARTHAM ("cartographie des habitats marins") project coordinated by the French Biodiversity Agency (Agence française pour la biodiversité, AFB). Digital data sources : Side scan sonar (2008), bathymetrics (2007), orthophotos (2008), historical maps (2009). Ground truth data sources (2012) : Diving with underwater cameras (2 points), direct human observations (2 points). Map confidence rated by Ifremer : 82%.

  • Seabed habitat map (Habitat Directive classification system) performed by Stareso, Evemar and Sintinelle within the framework of CARTHAM ("cartographie des habitats marins") project coordinated by the French Biodiversity Agency (Agence française pour la biodiversité, AFB). Digital data sources: sonar (2010-2011), orthos (2010-2011), historical data (Pasqualini, 1997) Ground truth data sources (2002-2012): diving, sea-viewer, direct human observations Map confidence rated by Ifremer : 87%

  • Updated habitat map resulting from an intergrated analysis of the acoustic and ground truth survey data in 2014 (onboard the RV Cefas Endeavour). Broadscale habitats at each ground truth station were used to inform a semi-automated mapping process using object-based image analysis (OBIA). The majority of the seabed was classified as the BSH 'A4.1 High energy circalittoral rock/A4.2 Moderate energy circalittoral rock', with a with a large sediment bank in the north of the rMCZ made up of the BSHs 'A5.1 Subtidal coarse sediment' and 'A5.2 Subtidal sand'.

  • Broadscale habitat (EUNIS level 3) for Land's End (Runnels Stone) recommended Marine Conservation Zone (rMCZ) Updated habitat map resulting from an intergrated analysis of the acoustic and ground-truth survey data from 2013 (onboard the Coastal Survey Vessel (CSV) Water Guardian on cruise wgdn0112). Sediment types at each groundtruthing station were used to inform a semi-automated process of map production using object-based image analysis (OBIA).
