  • 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.

  • 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.

  • 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.
