Founded in 1921, the International Hydrographic Organization, which has its head office in Monaco, is an intergovernmental organisation that, together with its member states, ensures that all physical characteristics of the oceans are measured and mapped in order to ensure the safety of navigation and to preserve the marine environment. These characteristics include sea level, the topography of the sea floor (mountains, volcanoes, ravines, etc.), ocean currents, etc. This information helps to establish uniformity for nautical charts, and is also useful for activities associated with renewable marine energy.
