  • In May 2008 (18-27 May), a survey commissioned by JNCC undertook seabed habitat investigations of two Areas of Search (AoS) for offshore SACs. The objectives of this survey, within the Submarine structures in the mid-Irish Sea AoS and the Solan Bank AoS, were to acquire high quality acoustic data capable of identifying and delineating habitats listed under Annex I of the 1992 EC Habitats Directive; primarily the Annex I habitat Submarine structures made by leaking gases in the former AoS and Annex I Reef habitat in the latter AoS. Surveys consisted of both broad-scale and fine-scale acoustic techniques, utilising sidescan sonar and multibeam swathe bathymetry, along with a variety of ground-truthing techniques including towed and drop down video/stills and Hamon grab sampling. A Rock dredge was also used at a few stations in order to gather samples of epibiota from hard substrata to assist with the taxonomic identification of the video and still images. The range of sampling techniques employed ensured that any Annex I habitats could be adequately described and characterised. For both AoSs survey planning and interpretation of survey data utilised extensive pre-existing data sets.

  • 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.

  • Opportunistic survey of the sandbank in offshore waters east of the Isle of Man as part of JNCC offshore Natura 2000 site assessment processes. Grab sampling, AGDS, side scan sonar and video data were obtained on 3 separate cruises. Data was worked up by AFBI and QUB as part of an MoA between JNCC and AFBI/DARD (NI).

  • This data was gathered as part of the MESH SW Approaches canyons survey; a collaborative survey involving the Joint Nature Conservation Committee, the Marine Institute, the British Geological Survey and the University of Plymouth. Defra Natural Environment Group Science Division (CRO 361) made a significant contribution to this work. The work contributed to the MESH project that received European Regional Development Funding through the INTERREG IIIb Community Initiative. The aims of the survey were to acquire high resolution multibeam, sub-bottom profiler and seabed imagery data in the SW Approaches area, located approximately 320km southwest of Land's End. The cruise not only mapped the variable morphology of the area, but also investigated the biological communities within the canyon system for the assessment of a potential SAC under the EC Habitats Directive. The cruise also tested the application of the survey standards and protocols developed under the MESH project. The cruise was the first thorough test for the recently completed MESH Guidance Framework, providing a 'proof of concept' from planning to completion.

  • Two surveys of the sediments and macro-invertebrates of intertidal areas of the Wash were undertaken during late September to early November 1998 and 1999. In 1998, 113 sites, each 1 ha in area were sampled, 91 of which were sampled in Institute of Terrestrial Ecology's survey of 1986. In 1999, 103 sites were sampled, 82 of which had been first sampled in 1986.

  • Acoustic mapping of the seabed of the Menai Strait. Local classification, seperated into acoustic ground characteristics: hard/soft and smooth/rough. Swellies.

  • 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.

  • 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.

  • SeaMap were contracted by SNH to review and analyse acoustic data collected from the sea around St Kilda and to interpret these data using ground truth records.

  • Data that contributed to the MB0102 Task 2I English intertidal habitats dataset. Originally produced as part of the Iterreg IIIB Harmonised River Basins Strategies North Sea (HARBASINS) project.
