World Hydrography Day

[1] The International Hydrographic Bureau was established in 1921 for the purpose of providing a mechanism for consultation between governments on such matters as technical standards, safe navigation and the protection of the marine environment.

The IHO is actively engaged in developing standards and interoperability, particularly in relation to the challenges brought about by digital technologies.

[2] In 2005 the IHO adopted the concept of a World Hydrography Day, which was "welcomed" by the United Nations General Assembly in Resolution A/RES/60/30 Oceans and the law of the sea.

[4] World Hydrography Day[5] was adopted, in the words of the UN,[3] with the aim of: ... giving suitable publicity to its [IHO's] work at all levels and of increasing the coverage of hydrographic information on a global basis ...Translation of this aim through World Hydrography Day is achieved by the nomination of a theme for each year's celebration.

The theme for 2022 is: "Hydrography - contributing to the United Nations Ocean Decade" Previous themes were: Member states of the IHO, as well as international and national hydrographic organisations and services worldwide, engage in a range of activities on or around 21 June each year to mark World Hydrography Day.
