The purpose of this benthic survey (cruise 1211S) south-west of Scalloway, Shetland Isles, was to improve knowledge of the occurrence and distribution of species and habitats of recognised conservation importance, particularly priority marine features (PMFs). An underwater video and still photograph survey was conducted by MSS for MSS on the 16th October 2011 to collect detailed biological information on the seabed species and habitat features present. Drop-down video drift tows were undertaken at 3 sites in the area. The images, analysed under SNH contract by Dr Colin Moore, were used to describe the nature of the seabed in terms of the physical structure and the species assemblages. MSS used the vessel MRV Scotia for this survey - footage was collected from Fetlar and off Armadale on the same cruise.
