This report is a contribution to the Strategic Environmental Assessment (SEA3) conducted by the Department of Trade and Industry (now Department of Energy and Climate Change). It provides an overview of the various management plans which have been developed for the coastal zone, coastal defence, estuaries, biodiversity and coastal habitats in the SEA3 area of the North Sea. Numerous dynamic processes, both natural and man-made, affect the SEA3 coastline. After reviewing these processes, the report reviews the various coastal initiatives and management strategies which have been established to minimise their detrimental effects. Various coastal fora provide a lead in developing management strategies for the enhancement and protection of the environment in their areas. Plans include European marine site management schemes, shoreline management plans prepared by coastal defence authorities, estuary management plans, coastal habitat management plans and biodiversity action plans.

As part of the Department of Trade and Industry (now Department of Energy and Climate Change) Strategic Environmental Assessment for Area 6 (SEA6) an environmental survey was carried out from Kommandor Jack during October 2003. The aim of the survey was to acquire seabed and water samples for biological, physical and chemical analysis together with video and digital stills photography to ground-truth the geophysical data ans enable a general characterisation of seafloor habitats and community types present within a number of offshore areas containing pockmarks and shallow gas seeps within the Irish Sea. The areas surveyed were: St Georges Wall; Yuan's Pockmarks; Pisces Reef; Texel 11, Codlings Extension; Harvey's Trench; Texel 10. This report provides a log of the field sampling work undertaken.

As part of the Department of Trade and Industry's (now Department of Energy and Climate Change) Strategic Environmental Assessment (SEA2), this report briefly describes the evidence for the origin of shallow gas in Outer Moray Firth open blocks 15/20c and 15/25d. Sea floor pockmarks are known to occur within these blocks, and they indicate the seepage of gas from shallow levels into the local water column. An environmental concern is that any industry activity in these blocks must not plumb into any component of the system that is sustaining the gas seepages at sea bed. The study area covers two part-blocks within the eastern part of the Witch Ground Graben within the UK Central North Sea. This study follows on from the DTI 2001 SEA research on pockmarks.

This report is a contribution to the Strategic Environmental Assessment (SEA3) conducted by the Department of Trade and Industry (now Department of Energy and Climate Change). This report summarises sites which are protected for reasons other than nature conservation in the SEA3 area of the North Sea. They include sites of geological importance, archaeological importance, sites of designated water quality for bathing, and areas of bivalve shellfish production. Sites of geological importance include Geological Conservation Review sites (GCRs), geological Special Sites of Scientific Interest (SSSI) and Regionally Important Geological and Geomorphological sites (RIGS). Sites of archaeological importance include wrecks and scheduled monuments. A large number of wrecks exist in the SEA3 area, most uncharted. The majority of wrecks are found in coastal waters. Important historic wrecks in UK waters are protected under the Protection of Wrecks Act 1973. Water samples are regularly taken from numerous beaches along the east coast for physical, chemical and microbiological analysis. Bathing beaches are classified according to national and European standards for quality. In the UK, shellfish for human consumption must be harvested from designated production areas.

As part of the Department of Trade and Industry's (now Department of Energy and Climate Change) Strategic Environmental Assessment (SEA6) a seabed survey was carried out. The survey comprised photography and seabed sediment and water sampling. The purpose of these surveys was to shed light on the distribution and extent of methane-derived autigenic carbonate (MDAC) in the Irish Sea. 942 photographs are available. Cruise report is available.

This report describes fieldwork operations of the North Sea Strategic Environmental Assessment (SEA2) Survey, Leg 3 (crests survey) conducted for he Department of Trade and Industry (now Department of Energy and Climate Change) from R/V Vigilance between 14 and 22 June 2001. The survey objectives were to carry out quantitative seabed sampling and seabed photography in SEA2 Survey Area 1 (sand bank / wave study areas, off the Norfolk coast). The report contains a brief description of seabed appearance and epifauna. 82 samples were collected.

This report is a contribution to the Strategic Environmental Assessment (SEA5) conducted by the Department of Trade and Industry (now Department of Energy and Climate Change). The purpose of this report is to present an up-to-date synthesis of current information on the benthic environment and the benthic communities and associations in the Strategic Environmental Assessment (SEA) region 5 and, additionally, to highlight areas considered to be particularly vulnerable to anthropogenic influences. The synthesis has been prepared from the information available on seabed habitats, species and communities to the east of Orkney and Shetland and extending down the east coast of Scotland. The area includes the major east coast features, the Moray Firth, the Firth of Forth, and the Tay estuary, and the inner Firths of Dornoch, Cromarty and Inverness, the Ythan Estuary and the Montrose basin.

This report is a contribution to the Strategic Environmental Assessment (SEA4) conducted by the Department of Trade and Industry (now Department of Energy and Climate Change). The report identifies coastal and near-shore conservation sites within the SEA4 area which are protected by international, national and local conservation designations as well as describing the sites and reasons for their protected status. At the northern extremity of Britain, the SEA4 area combines very productive waters with spectacular and distinctive coastal scenery. The combination of rich food sources and relative lack of disturbance make it host to abundant bird populations, including rare species not found elsewhere in the United Kingdom. Among the conservation sites are sea inlets, mud and sand flats, lagoons, salt marshes, sand dunes, shingle, sea cliffs, fresh water bogs and marshes, heath, scrub and grassland.

As part of the Department of Trade and Industry's (now Department of Energy and Climate Change) 1999 Strategic Environmental Assessment SEA1 (White Zone) Environmental Survey: Seabed survey of the deep-waters to the north and west of Scotland. The aims were to : Complete TOBI sidescan sonar survey of the "White Zone" begun on RRS Charles Darwin cruise 119C leg A; To carry out photographic surveys of the "White Zone" to ground truth the sidescan sonar imagery and provide an assessment of the seabed fauna; To carry out seabed sampling to further ground truth the sidescan sonar imagery and generate samples for the future analysis of selected environmental parameters (hydrocarbons, elements, particle size). 39 samples were collected. Raw TOBI Bathymetry - includes sidescan sonar, sub-bottom profiler and magnetometer data and Mosaiced TOBI sidescan imagery are available. The survey report is also available. The preliminary report describes the data collection and interpretation carried out by Southampton Oceanography Centre in the summer of 1999 on behalf of the DTI. The areas surveyed were in unlicensed parts of the UKCS NW of Scotland, and the purpose of the work was to obtain regional environmental information. The work was carried out in two survey legs, Leg A was a regional side-scan sonar survey, whilst leg B was a seafloor survey of targets selected from the results of leg 1. This report is presented in 4 sections: Section 1 - Cruise report for Leg A; Section 2 - Cruise report for Leg B; Section 3 - Regional environmental interpretation from side-scan sonar and camera data; Section 4 - Initial environmental assessment.

This report is a contribution to the Strategic Environmental Assessment (SEA6) conducted by the Department of Trade and Industry (now Department of Energy and Climate Change). This report provides a synthesis of current knowledge of the benthic communities and seabed habitats in the Clyde Sea, which abuts the northern end of the SEA6 area. The Clyde Sea is a fjordic system consisting of drowned, glacially over-deepened, valleys separated by sills. The southern limit of the area, and the ultimate sill for the Clyde Sea lochs, is formed by a broad sill termed the Great Plateau. The Great Plateau is predominantly less than 50 m deep and is overlooked by the volcanic plug of Ailsa Craig. The report is presented in the context of the hydrography and sedimentology of the area. The focus is on dominant species and broad descriptions of community types (biotopes). It also reviews existing major human activities in the area that are currently affecting the benthos.
