This is the first map of reefs in Bulgarian Black Sea drawn based on expert interpretation of the following data: point data on the type of substrate (sediments, hard), rock samples, sediment thickness over bedrock determined by divers, acoustic profiling of the seabed morphology.

Map of broad habitat types in Bulgarian Black Sea shelf which equate to one or more habitat types of the EUNIS classification

Map of benthic biotopes in the sediments in part of Natura 2000 SAC Ropotamo, the Bulgarian Black Sea. The biotopes were defined based on the sediment type, depth range and the typical associated macrozoobenthos communities as differentiated by multivariate similarity analyses.

This is the first map of sandbanks in Bulgarian Black Sea drawn based on expert interpretation of the following data: point data on the type of substrate (sediments, hard), grain size of sediments, sediment thickness determined by divers, acoustic profiling of the seabed morphology.

Surveys undertaken in Lough Foyle (Aug 2009), Carlingford Lough (Aug-Sep 2012), Strangford Lough (Aug-Sep 2012) and Dundrum Bay (Jul 2012). These surveys are done primarily as part of a rolling 6 year programme for the EU Water Framework Directive. These polygons were mapped and merged to collate inter-tidal seagrass surveys originally assessed as part of the Water Framework Directives suite of Biological Quality Element tools. The data collected can also be used to inform the habitat map as it corresponds to the Eunis code 'A2.611-Mainland Atlantic Zostera noltii or Zostera angustifolia meadows'. Surveys undertaken by Quercus at Queen's University, Belfast on behalf of the Department of the Environment, Northern Ireland (DOE). Subsequently translated into EUNIS habitat classification scheme.

Miesmuschelbänke im Niedersächsischen Wattenmeer 2009. Im Rahmen des Miesmuschel Managementplans wurden jährliche Kartierungen der eulitoralen Miesmuschelbänke im Niedersächsischen Wattenmeer durchgeführt. Die Erfassung erfolgte mittels stereoskopischer Auswertung von Luftbildern. Die Befliegungen fanden im Frühjahr bzw. Sommer flächendeckend statt. (Deutsch), Blue mussel beds in the Wadden Sea of Lower Saxony 2009. The intertidal blue mussel beds were determined yearly in the scope of the blue mussel management plan. Aerial surveys were carried out and aerial photographs were analysed by using a stereoscope to detect the mussel beds. (Englisch)

Under the MeshAtlantic project (2010-2013) the habitat of an area off the south coast of Portugal (Sagres) was classified. The biological data was gathered from surveys carried out during 2012. Stratified sampling by depth and bottom substrate was performed using underwater visual census, Van Veen grab and beam trawl to estimate fauna densities and quadrate method to estimate macroalgae coverage. Additional and significant data was obtained from image analysis of video records collected during Remote Operated Vehicle (ROV) surveys carried out under the UALG/CCMAR programme or from strict cooperation with the NGO OCEANA. Both these surveys began with a previous acoustic mapping of the seabed by means of Side Scan Sonar and Multi-beam, followed by sediment type classification and ground truthing validation using Van Veen grab sampling.
