Ifremer strives to gain fuller knowledge of the oceans and their resources, monitoring marine and shoreline environments as well as promoting the sustainable development of maritime activities. With this as a backdrop, the institute operates or contributes to various observation systems: oceanographic vessels and submersibles, automated observatories (buoys, floats), satellites, networks of scientific observers or volunteer observers (sea professionals or general public). All these systems produce large quantities of data on the state of the oceans which must then be organised, analysed and shared.
