Abstract More and more research work on marine environment is based on the analysis of imagery. Thanks to technological development, we can now monitor ocean ecosystems using video cameras deployed on different platforms. Video acquisition provides information on organisms’ life and on environmental conditions. The sources of video data and the subjects of interest are many and varied: films from submersible dives in deep-sea environment, programmed video sequences of undersea rotary video stations in lagoons, high-frequency video data on deep-sea observatories, video observations recorded by fixed and autonomous camera devices on fishing gears, and others. The information contained in those images is essential to understand species biology and the functioning of these ecosystems, and ultimately inform environmental management policies. Because of the video data specificity (volumes, formats, diffusion…) a dedicated system has to be proposed for displaying and making accessible this huge archive of imagery, still growing every day.

In spring 2015 IFREMER opened a new web portal called “Marine Science Videos” ( The first objective of this video library was to give access to recent and historical images produced during the IFREMER submersibles dives (ROV Victor 6000 and Nautile). Users can view and search videos and photos by keywords or dive information (cruise, submersible, dive, year, zone, camera…).
Indeed, one or more submersibles can be deployed during oceanographic cruises in order to perform several dives lasting from some hours to some days. With their cameras catching videos throughout the dive they produce Tera Bytes of footages that are worth to be proposed to all IFREMER’S partners and to the public. The videos are available within three definitions (Low, Medium and High) in the MP4 H264 proxy format. Metadata relative to submersible dives and acquisition conditions are proposed together with this data: submersible position and attitude, temperature and salinity conditions, camera position and configuration. Comments recorded simultaneously with the videos are displayed if existing.
Furthermore, images acquired during corresponding operations are accessible in addition to the videos:
• Thumbnails: also called « mini-films », these images result from an automatic video sampling at a given frequency.
• Images: these are photos from the submersible digital camera and video snapshots.

Thumbnails, Low Definition images and videos are downloadable without restriction. Medium and High Definition versions can be used by authorised persons or on demand.
