Scleractinian distribution (Madreopra oculata and Lophelia pertusa) reported from 1995 to 2013 in the French Mediterranean Sea

Species distribution

In the Mediterranean deep-sea two scleractinian species, Lophelia pertusa (= Desmophyllum pertusum) and Madrepora oculata, make up the dominant structure-forming corals. The Lacaze-Duthiers canyon is the only French Mediterranean canyon where the two species L. pertusa and M. oculata have been observed living together in large quantities, the situation generally described for the biocoenosis of cold-water corals (CWC). In this canyon large colonies (more than 40 cm) of both species of scleractinians were observed at depths ranging from 246 m to 541 m at the head of the canyon and its western flank. The second canyon is the Cassidaigne canyon, where M. oculata seems to be the only structure-forming scleractinian there. The largest concentration of M. oculata colonies was observed on the west flank of the canyon along a crest at depths ranging from 200 to 210 m. Mature M. oculata colonies attained heights up to 40 cm. M. oculata were observed in three other canyons: Bourcart, Sicié…

Data origin:

Data are intended to be research-quality. Precision of geographical data is dependant on the precision of the navigation at the time of the underwater gear dive. Data was collected and identified using videos and High Definition images taken by manned submersibles or Remote Operated Vehicles (ROVs). Identification of species is based on images. Geographical coordinates of occurrences are based on navigation tracks of underwater gears. Data used to build this dataset come from the following cruises: CYATOX_1995, MARUM_2009, ESSROV_2010, MARUM_SECKENBERG_2011, ESSNAUT_2013, MEDSEACAN (2008-2009)
