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.

The Russian Hydrographic Office was founded in 1777 by the Admiralty Board of the Russian Empire. The hydrographic service in Russia has been historically attached to the Russian Navy and the agents and supervisors of hydrographic works have been largely naval officers since it was established. Having operated under different names along its history, the Russian Hydrographic Service is one of the first hydrographic offices in the world.
