ANNEX I habitat for Anton Dohrn Seamount
The cruise took place between the 1st and 29th of July 2009 and surveyed two Areas of Search (AoS) for offshore Special Areas of Conservation (SACs): Anton Dohrn Seamount located 155km west of the St Kilda archipelago, and East Rockall Bank located 260km west of the St Kilda archipelago. The main aims of the survey were to acquire acoustic and photographic ?ground-truthing? data to enable geological, geomorphological and biological characterisation of the Anton Dohrn Seamount and East Rockall Bank AoS. Specifically, the data acquired will lead to the production of broadscale habitat maps, the identification and description of Annex I reef habitats with particular attention to the occurrence of bedrock, stony and biogenic reef, to identify and record any anthropogenic impacts in the areas of search and finally to evaluate data acquisition methods, techniques and equipment.

The M/V Franklin is fitted with a Kongsberg EM710 multibeam echosounder system designed for high-resolution sea-bed mapping in water depths of up to 2000m. The operating frequency range for the system is 70-100 kHz. The multibeam echosounder data acquired during this survey was processed during the cruise by MMT AB staff with remaining processing being carried out post-cruise in advance of final data delivery on the 31st August 2009. Overall, good quality data were obtained and are a significant improvement on the existing multibeam echosounder data acquired during surveys in 2005.
MMT ABÔÇÿs ROTV was offered as an alternative to the EdgeTech 2400-DSS sidescan sonar for use in shallow water (<300m). This piece of equipment provided a steerable vehicle with both sidescan sonar and CHIRP sensors. The ROTV is fitted with an altimeter to help ensure that the equipment maintains an even height above the seafloor. The FOCUS II uses fibre optic telemetry for vehicle and sensor communication providing high data capacity. The system comprised the towed platform together with a user selected instrumentation package; an electro-optic tow cable and a winch with a combined fibre optic & electrical slip ring and a user friendly control and display unit with input and output for user selected sensors and instruments. The system was operated to 400 metres water depth at 5 knots with a layback of up to 1 kilometre. The vehicle was deployed from the A-frame at the stern of the ship using its own dedicated winch.
The Seatronics drop frame camera system was designed to replicate what was used on the 2006 SEA7 and the 2007 Canyons surveys for the DTI and JNCC to maximise comparative data analysis. It was deployed from the starboard side of the vessel. The system comprised a 5 megapixel Kongsberg and Imenco digital stills camera, and an integrated DTS 6000 digital video telemetry system. Both video and stills cameras were mounted at an oblique angle to the sea bed to aid in species identification. Sensors monitored depth, altitude and temperature, and a USBL beacon provided accurate position data for the equipment during data acquisition. The drop frame camera system included four Mk2 SeaLED lamps which produce a typical 1067lux at 1m. These were mounted obliquely, similar to the video and stills cameras, to maximise the illumination of the areas of sea bed covered by the video and stills cameras and to aid in biological species identification.
