The images collected with the H-ROV Ariane were used to build 3-Dimensional models of coral assemblages living in the Lacaze-Duthiers Canyon (CALADU 2019 oceanographic cruise). 3D-models were built using the ‘Structure from motion’ technique available in the Matisse software. 3D-representations provide an overview of marine habitats at a scale larger than what is seen in the field of view of a camera and allows having an overview of a marine ecosystem cleaned of the turbidity and color attenuation that are inherent to the underwater environment. Two scleractinians species forming bushes several meters high are seen in this video clip : Desmophyllum pertusum (syn. Lophelia pertusa) and Madrepora oculata.
