UNESCO, the Intergovernmental Oceanographic Commission (IOC) of UNESCO, awarded Nausicaa , for the first time in the world, the title of 'Centre of Excellence' to Nausicaa for its contribution in raising awareness of the marine environment. To this title, awarded for a renewable three-year period, UNESCO added its support for the Centres promoted.
Since 1998, a partnership has been in progress between Nausicaa and UNESCO
The latter above all supported Nausicaa in the opening of its extension and contributed its name, under the auspices of the International Year of the Ocean, to operations such as the European Children's Diving Days and the World Festival of Underwater Images.
For its part, Nausicaa provided a facility for signing the Ocean Charter by the public during the International Year of the Ocean, in 1998.
The city of Boulogne-sur-Mer, the leading French fishing port, was one of the first townships to invite its citizens to adopt this Charter. To further this action, Nausicaa organised with UNESCO the First International Symposium on Aquariums, Museums and Science Centres during which about sixty representatives of institutions of the marine world committed themselves to inform their populations of the resources of the oceans and their best forms of management.
