Mapping of the Vatika Bay seafloor has been conducted in two different periods: in June 2010 and May 2015.The shallow, northern part of the Bay has been mapped in 2010 during the research project "PAVLOPETRI" by means of swath bathymetry (RESON SeaBat 7125 200/400 kHz), side scan sonar (Geoacoustics 100/400 kHz) and pinger (3.5 kHz) subbottom profiler. The deeper seafloor of the Bay has been surveyed in 2015 by means of side scan sonar and chirp subbottom profiling for the purposes of the research project "Environmental Study of Vatika Bay", funded by the Prefecture of Peloponnese. The research vessel "ALKYON" has been used in both cruises. The description of the nature of the seafloor and the habitat mapping has been based mostly on the interpretation of the acoustic-geophysical data and Sentinel-2 satellite imagery, as well as secondarily on the limited sampling performed in the area.

TMarine Habitat Directive Annex I habitats in the Danish Wadden Sea. The habitats were mapped in the period 2004-2018.

The Algarve coast presents a significant portion of territory that is part of the designated National Nature Reserve, in its underwater slope (0 to 30m depth - RENSUB), especially when compared with the equivalent on land. The current digital map presents the EUNIS habitat of the central Algarve RENSUB coast. The covered area is between Albufeira and Vale do Lobo. The sediment classification was obtained through the interpretation of data from Side Scan Sonar (remote-sensing image), while for the habitat mapping the biological sampling was carried out with beam trawl and underwater visual census.
