Broadscale habitat (EUNIS level 3) for Farnes East recommended Marine Conservation Zone (rMCZ)

Description

A broadscale habitat feature class was created to illustrate predicted extent of broadscale habitats present at Farnes East rMCZ. These broadscale habitats include 'Moderate energy circalittoral rock', 'Subtidal coarse sediment', 'Subtidal sand', 'Subtidal mud' and 'Subtidal mixed sediments' as determined from particle size analysis of sediment samples and descriptive analysis of still images from underwater camera data. The assigned classes at each ground-truth stationwere used to inform the semi-automated process of map production using object-based image analysis (OBIA)in combination with regression kriging. Groundtruthing data collected during 2012 on the RV Cefas Endeavour (surveyID CEND0412). Classification system details: EUNIS habitats and a separate FOCI layer. Survey technique details: 0.1m2 mini Hamon grab; Camera sledge; multibeam data colected by EGS under contract in 2012.
