The primary objective of this survey was to fill data gaps - improving knowledge on the distribution biotopes of recognised conservation importance. A total of 42 video stations and 10 grab stations were surveyed over two days in August 2016.

Ten grab samples were collected throughout the lochs using a 0.1m2 Day grab. Each infaunal sample was passed through a 1mm mesh sieve, and the residue retained and fixed using buffered formalin. A small sub-sample was removed from each grab for Particle Size Analysis (PSA) which was stored frozen until laboratory analysis. Laboratory methodologies were undertaken in line with NMBAQC Scheme guidelines. Identification of infaunal samples was to the lowest possible taxonomic level (e.g. species). Measurements (max length) of up to 50 live maerl fragments were undertaken from six grab samples. At one station, Limaria hians speciemens were also measured to the nearest mm. Video images were obtained from 42 drop-down video drifts. The video frame carried a laser scaling system and the facility to take digital still photographs at intervals. Video overlay display provided date, time, and position data along runs. Depth details were provided for the start and end of the runs. Analysis of the video footage was undertaken to describe the physical structure and species assemblages present. Species present were identified and quantified using the semi-quantitative MNCR SACFOR scale, as far as possible. Biotopes were allocated based on the biological and physical attributes. SNH contracted Dr Colin Moore to analyse the underwater video footage from this survey and Precision Marine Survey Ltd to undertake faunal analysis and PSA of the samples from this survey.
