2014 Scottish Natural Heritage (SNH) Fetlar to Haroldswick MPA (Shetland Islands) benthic camera survey
The main aim of this survey in the Fetlar to Haroldswick MPA, north-east Shetland Islands was to improve knowledge of the occurrence and distribution of the species and habitats of recognised conservation importance. The survey was undertaken by SNH and Marine Scotland Science (MSS) on board the MRV Alba na Mara (cruise 1414A) on the 15th and 16th August 2014. A drop-down video survey of benthic habitats was undertaken at 21 sites within the MPA. Analysis of seabed video and still photographic imagery is used to describe the nature of the seabed in terms of the physical structure and the species assemblages. Runs and run segments were assessed for the presence of protected features and other PMFs, as well as for the presence of species and habitats of recognised conservation importance. This survey was part of a two week research cruise undertaking work in the MPAs Wester Ross, Fetlar to Haroldswick, Mousa to Boddam and Noss Head collecting drop-down video footage, grab samples and sandeel dredge tows.

This subtidal seabed data from the Fetlar to Haroldswick MPA in north-east Shetland was collected during a research cruise run by SNH on board the MSS vessel MRV Alba na Mara (cruise 1414A) on the 15th and 16th August 2014. Video images were obtained using a Kongsberg video camera 14-366-1306 from 21 drop-down video drifts that each lasted a minimum of 5 minutes, with the speed of tow varying depending on the weather. The video footage was recorded to a Panasonic DMR-EX83 DVD recorder straight to DVD. Track position and depth data were displayed on a SD video overlay system. HD video footage was recorded at a resolution of 1920x1080. The drop down video camera frame was custom built and also carried a vertically orientated digital stills camera, which took photographs of the seabed opportunistically if specific features of interest were encountered, and a laser scaling system. Analyses of the video footage was undertaken by SNH contractor Dr Colin Moore 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. Where the video run traversed a sequence of biotopes, the run is split into corresponding segments with the transition points recorded using the time, position and depth.
