Broadscale habitat (EUNIS level 3) for East of Haig Fras recommended Marine Conservation Zone (rMCZ)

Description

Updated habitat map resulting from an integrated analysis of the 2012 (CEND 3/12a) and 2013 (CEND 5/13) dedicated survey data for East of Haig Fras recommended Marine Conservation Zone (rMCZ). It shows the seabed at the site to be a heterogenous fine scale mosaic of sand, coarse and mixed sediments, with mud habitat in deeper areas. The two broadscale habitats ÔÇÿA5.1 Subtidal coarse sedimentÔÇÖ and ÔÇÿA5.4 Mixed sedimentsÔÇÖ are presented as a complex ÔÇÿA5.1/A5.4 Subtidal coarse/mixed sedimentsÔÇÖ. They show no differentiation in their acoustic or topographical properties that would allow them to be mapped separately. The ÔÇÿA4 Circalittoral rockÔÇÖ habitat is present in scattered small patches. Created with Object Based Image Analysis (OBIA) on acoustic data and groundtruthed samples. Acoustic data gathered by Gardline under tender, groundtruthing gathered by Cefas on cruises CEND 3/12a and CEND 5/13.
