Portland Broadscale, Annex 1 Reef survey 2006/7
Broadscale EUNIS habitat map covering ~3,400 sq km lying >12 km off Portland/Lyme Bay, to the UK/France median line. Aimed at searching for Annex I 'Rocky reef' habitats. Based on expert interpretation of multiple data sets including using Benthic Terrain Modeller applied to full-coverage single-beam digital bathymetry (licensed from SeaZone), complementary Cefas acoustic surveys with directed ground truth sampling (video and still images), and the BGS seabed sediments chart modified according to the simplified 4-class Folk trigion used by MESH and EUNIS (Coarse, Mixed, Sand, Mud).
