In July 1994 a baseline survey was done to map the distribution of dead and living maerl. The survey was done using a RoxAnn acoustic system supported by direct observation of the seabed using a drop-down video camera and sediment samples collected by grab. Maps of bathymetry and predicted distribution of biotopes were prepared using GIS.

Use scores for soft or hard substrata as appropriate to the area surveyed.
