International Hydrographic Organization
The IHO was established in 1921 as the International Hydrographic Bureau (IHB). The present name was adopted in 1970 as part of a new international Convention on the IHO adopted by the then member nations. The former name International Hydrographic Bureau was retained to describe the IHO secretariat until 8 November 2016, when a revision to the Convention on the IHO entered into force. Thereafter the IHB became known as the "IHO Secretariat", comprising an elected Secretary-General and two supporting Directors, together with a small staff of 17, at the Organization's headquarters in Monaco.
