Survey at the Swallow Sand rMCZ, occupying stations on the pre-planned survey grid. A total of 104 stations were sampled, 103 by Hamon and 38 by camera sledge. On completion of the sampling grid an additional multibeam (bathymetry and backscatter) survey was undertaken in the western region of the rMCZ to target areas of coarse sediments identified to be present by the ground-truthing survey and the opportunistic multibeam survey.

A seabed survey for the purpose of habitat identification and mapping at the North St George's Channel recommended Marine Conservation Zone (rMCZ) site. Ground-truth sampling by grabs and underwater cameras (video & stills images). Multibeam bathymetry and backscatter collected opportunistically on transit between stations. Broadscale habitat (BSH) and habitat FOCI (Features of Conservation Interest) recorded at time of sampling and included in cruise/survey report. More in-depth interpretation to be made in a Post-Survey Site Report, following integrated assessment of acoustics and outputs from laboratory analysis of benthic samples.
