  • Study investigating scour and debris at Kentish Flats (Offshore Power) - 100% coverage of site. Hydrographic survey collecting acoustic data. Data collected and interpreted by in-house experts. Interpretation included the production of a seabed features chart for the area.

  • Intertidal biotope map of the Berwickshire coast from Fast Castle to Alnmouth Bay

  • This brief report presents the analysis completed to date. Little biological data exists for the majority of the deeper water of the Loch and for this reason the initial classification has been confined to habitat type.

  • Dataset covering the whole Belgian continental shelf; input to Marine Landscapes work; data has been verified

  • Intertidal mudflats around England

  • Methodologies for broad scale mapping of sublittoral habitats and biota based on acoustic remote sensing was developed as the Broadscale Mapping Project (BMP), a three year project funded by a consortium consisting of the Crown Estate, the Countryside Council for Wales, English Nature, Scottish Natural Heritage and Newcastle University through the SeaMap Research Group. The project was also supported by the European Commission?s Life programme. The Firth of Lorn study area was selected by Scottish Natural Heritage (SNH) because it encompassed a wide range of physical environmental conditions and had considerable existing conservation value. Part of the BMP study area was recently put forward as a possible Special Area of Conservation in recognition of the significant marine biological interest of both intertidal and subtidal rocky reefs. A nested survey strategy was developed for the Firth of Lorn which involved careful pre-planning and iterative field survey. By adopting this nested and iterative approach, the overall summary maps comprise a jigsaw of small maps where the underlying data vary in their level of detail. The main features and biota were mapped using acoustic remote sensing techniques combined with biological sampling. Linking the biological data with the acoustic data was completed using classification techniques developed for processing satellite images.

  • The survey of the marine environment in the Sound of Arisaig proposed SAC was undertaken by the BioMar Project, at the University of Newcastle, under contract to SNH. The Sound of Arisaig has an unusually high diversity of sublittoral sediment habitats within a relatively small area, and has rich maerl beds. This study was to map the pSAC and undertake further detailed studies of the maerl beds. Acoustic techniques were used validated by biological sampling using towed video and scuba divers. The data was stored and analysed using GIS.

  • Hydrographic survey of potential windfarm sites. Collection of acoustic data and interpretation undertaken by in-house experts. Interpretation included the production of a seabed features chart for the area.
