Multibeam echosounder data and seabed sampling data acquired during the 2011 MESH Atlantic survey were the primary sources of data used in the generation of this marine habitat map. Data on kinetic energy, derived from oceanographic models, and all of the interpreted survey data, were combined in a GIS environment and used to generate a EUNIS level 5 habitat map using the Maximum Likelihood Classification tool in ArcMap.

Statement
Multibeam echosounder data (MBES) were collected for the MESH Atlantic survey as part of the INFOMAR national seabed mapping project. The MBES data were classified into sediment classes using information from sediment samples. These sediment classes were classified into EUNIS level 5 habitat classes using biological sample data that had been grouped into similar classes using PRIMER. Kinetic energy data derived from oceanographic models in the bay were also incorporated into the final classification. Rock outcrops were digitised from shaded relief imagery and classified to EUNIS level 5 using video footage taken along transects of the rock outcrops.
