World Hydrography Day
World Hydrography Day, 21 June, was adopted by the International Hydrographic Organization as an annual celebration to publicise the work of hydrographers and the importance of hydrography, particularly in the promotion of safe navigation in international waters and ports, and the protection of marine reserves.
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. In 1970 the name was changed to the International Hydrographic Organization (IHO). The IHO is actively engaged in developing standards and interoperability, particularly in relation to the challenges brought about by digital technologies.
The date chosen for World Hydrography Day is the anniversary of the founding of the International Hydrographic Organization.
World Hydrography Day was adopted, in the words of the UN, 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. Once a theme is agreed, the member states, international and national hydrographic organisations and services develop activity programs and events that highlight that theme.
A theme for each World Hydrography Day is determined by the member states of the International Hydrographic Organization and is intended to promote the importance of hydrography internationally, multilateral cooperation and effective collaboration in data exchange, charting and standards development.
Recent themes have been:
- 2014: Hydrography - much more than just nautical charts
- 2013: Hydrography - underpinning the Blue Economy
- 2012: International Hydrographic Cooperation - supporting safe navigation
- 2011: Human Resources - The important element to the success of hydrography
- 2010: Hydrographic Services - the essential element for maritime trade
- 2009: Hydrography - Protecting the marine environment
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. These include:
