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.

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

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 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.

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 2010. 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 2010. 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)

The dataset is comprised of shallow-water (<30m) benthic habitat maps of the nearshore marine environment of two areas in Southwest Puerto Rico (PR), including the Guanica Bay/La Parguera region on the south coast and the Belvedere reserve on the west coast, which were mapped and characterized using visual interpretation of optical and acoustic remotely sensed imagery. The objective was to provide spatially-explicit information on the habitat types, biological cover and live coral cover of the region's coral reef ecosystem. These maps will be used to support marine resource management and conservation in the Commonwealth. In addition, the maps will enable change detection in an assessment of the effectiveness of restoration activities on the condition of adjacent coral reef ecosystems. This product provides a fine-scale assessment of the status, abundance, and distribution of marine habitats of Southwest Puerto Rico. Direct implications to management measures include evaluation of management efficacy, a spatial framework for improved monitoring sampling design, improved assessment of human-use impacts, and marine spatial planning to support alternative marine protected area boundary alternatives. In addition, the maps will enable change detection in an assessment of the effectiveness of restoration activities on the condition of adjacent coral reef ecosystems. This dataset provides an update to existing NOAA benthic habitat maps (created in 2001) of the waters off southwest Puerto Rico, extending from Guanica Bay in the east to Cabo Rojo in the west as part of a baseline characterization in support of watershed restoration. These fine-scale habitat maps, generated by interpretation of 2010 satellite imagery, provide an update to NOAA's previous digital maps of the U.S. Caribbean1 (GUI: PR004001, V1004001, VI004002) for these areas. Major improvements included: More detailed maps using a reduced minimum mapping unit from one acre to 1,000 square meters (~1/4 acre), Increased coverage of areas formerly classified as unknown, More detailed habitat classification, and Maps of marine areas adjacent to two natural reserves (Bosque Estatal de Guanica and Reserva Natural Finca Belvedere) in coordination with the NOAA Fisheries Caribbean Field Office. NOAA used a technique known as "heads-up digitizing" to produce the digital maps, whereby digital satellite images are visually interpreted, then habitats are delineated in a hierarchical classification scheme.
