| The Videocor 1 expedition had the double objective of conducting the first scientific cruise of the new born Hybrid-ROV Ariane and collecting data, images and samples from cold-water corals in the Parc National des Calanques, near Marseille, France. Photos and videos will be used to measure the surface covered by this ecosystem and calculate several metrics using 3D optical mapping to reconstruct geo-referenced and scaled 3D models of seafloor scenes from multiple image frames. Some colonies were also collected for the connectivity work package of the H2020-Atlas european project, both for reproductive studies of Madrepora oculata and for the assessment of Mediterranean-Atlantic genetic connectivity http://www.euatlas. org/. |

| The scientific cruise CALADU 2019 (dx.doi.org/10.17600/18000929), with the HROV Ariane, onboard the research vessel L'Europe, took place in the Mediterranean Sea, off the coast of the Occitannie Region, in the Lacaze-Duthiers canyon. The CALADU expedition had the objective of collecting data, images and samples from cold-water corals in the Lacaze-Duthiers canyon. Acoustic multibeam data were collected in order to draw a high resolution bathymetric map of the western flank of the canyon. Photos and videos will be used to measure the surface covered by this ecosystem and calculate several metrics using 3D optical mapping. Multiple image frames will be used to build geo-referenced and scaled 3D models of seafloor scenes. Some colonies were also collected for... |

| This Videocor1-02 expedition (September 2017) was done in order to complete the VIDEOCOR1 expedition that took place in May 2017. The objectives were to deploy the Ariane HROV to complete the video and photo coverage of white corals (Madrepora oculata) in the Cassidaigne canyon and to explore areas predicted by a habitat suitability model. No samples were collected. In total, we were granted three additional dives and all three were executed due to excellent weather conditions. The H-ROV Ariane had no technical problems. No samples were collected. The three dives allowed to complete the video coverage of two sites: Cassis-200 and Wassis-Wall. · Cassis-200: the coverage of the southern part could be completed without any problems because there was no water... |
