    The result of a multidisciplinary field survey of the Haig Fras SAC which was initiated in January and completed during March/April 2011. The current study was initiated to investigate the extent of Annex I reef habitat at Haig Fras. Cefas and JNCC collected full-coverage multibeam bathymetric and backscatter data and associated ground-truthing data. This data has been analysed to update the extent of the Annex I reef and produce a broadscale habitat map. Seven biotopes were identified from drop camera transects with the predominant biotope characterised by Devonshire cup corals, sponges and crustose communities on wave-exposed circalittoral rock. The broadscale habitat map indicates the presence of four main biotopes; high energy circalittoral rock, moderate energy circalittoral rock, deep circalittoral coarse sediment and deep circalittoral sand.

    The purpose of this study was to re-survey six locations on the rocky shore within the Teesmouth and Cleveland Coast European Marine Site which had originally been surveyed in November 2003 in order to make an assessment of these habitats as a food resource for shorebirds. The original survey also provided data on the biotope composition and biodiversity of the site in order to inform Natural England on the status of the large shallow inlets and bays feature of the site.

    The purpose of the current study was to initiate site condition monitoring of the reefs of Loch Creran. This was done to establish a baseline biological data set that would facilitate the assessment of the condition of the reef habitats in the future and to allow a judgement to be formed on the current condition of these habitats. The approach taken to achieve these objectives was to assess the extent and distribution of serpulid reefs from observations by diver along 110 transects around the loch. Detailed studies were also performed at four of the major serpulid reef sites in the loch. Here, distribution was examined with sidescan sonar, reef density by video and the community of organisms associated with the habitat by diver survey of the reefs themselves and of the surrounding sediment. The distribution and abundance of Modiolus was examined along seven relocatable transects and, at one of the major mussel beds, the size structure of the population and associated community surveyed. Subtidal rocky reefs were surveyed by diver along relocatable transects at three sites.

    Emu Limited was commissioned by Natural England to carry out an acoustic and ecological survey of the subtidal zone (areas below the Mean Low Water mark) within the Solent Maritime Special Area of Conservation (SAC). The remit of the survey was to produce data and maps characterising the overall subtidal seabed surface topography, surface sediment composition and the main subtidal biotopes which fall within the Solent Maritime SAC's designated boundaries using rapid field assessment techniques with the minimal environmental impact.

    Within the last 5 years, widespread uptake of multi-beam sonar technology within the offshore survey industry has meant that swath bathymetry is becoming economic even within the nearshore region. As a result, the Southeast Strategic Regional Coastal Monitoring Programme has been able to upgrade their single-beam bathymetric surveys to achieve 100% seafloor coverage to IHO Order 1a standard through collaboration with the Maritime and Coastguard Agencyâ??s Civil Hydrography Programme. Although the main purpose is to survey the bathymetry of the seabed, the full coverage bathymetry combined with acoustic backscatter information collected during the swath bathymetry survey can be integrated with ground-truthing information to produce a series of detailed maps.
