The Spanish Institute of Oceanography is a public research body devoted to research into marine sciences, especially in terms of the scientific knowledge of oceans, sustainability of fisheries resources and the marine environment. IEO depends on the Ministry of Economy and Competitiveness, directly reporting to the Secretariat of State for Research. IEO not only carries out basic and applied research, it also provides scientific and technological advice to administrations on matters relating to oceanography and marine sciences. In addition, it is Spain's scientific and technological representative at most of the international forums and bodies related to the sea and its resources. IEO has a wide geographical coverage with nine oceanographic centres, five plants for marine fish farming testing, twelve tide gauge stations, a satellite receiving station and an oceanographic fleet.
