World Hydrography Day is celebrated every year on June 21 to highlight the importance of hydrography as an applied science that can support the sustainable use of the oceans. This day also highlights the relevance of the activities of hydrographers and raises awareness of the importance of the oceans and waterways to human lives. WHD was established by the International Hydrographic Organization (IHO) in 2005 and has also been adopted by the United Nations General Assembly.

Significance of World Hydrography Day
Proper application of hydrography can produce updated surveys and data can be used for initiatives for the protection of the marine environment. Hydrography can even be used for the management of other components of the blue economy like coastal zone, marine protected areas, marine spatial data infrastructures, and renewable energies. To celebrate the multiple benefits of hydrography for the environment, World Hydrography Day is observed every year on June 21. The day also provides opportunities to honor the work and services of national hydrographic offices, industry partners, expert contributors, and the scientific community. Additionally, WHD even sheds light on the ability of hydrographers to gather and manage marine data and their strength in technical collaboration on a global scale.
Definition of Hydrography & Its Importance
Hydrography is a branch of applied sciences involved in the measurement and description of the physical features of water bodies including oceans, coastal areas, seas, rivers, and lakes. It also deals with the prediction of their change over time to ensure the safety of navigators and in support of all other marine activities such as scientific research, economic development, environmental protection, and security and defense. Other than this, hydrography applications also include:
- resource exploitation
- coastal zone management
- environmental protection and management
- national marine spatial data infrastructures
- maritime boundary delimitation
- maritime defense and security
- tsunami flood and inundation modeling, etc

International Hydrographic Organization
The International Hydrographic Organization (IHO) is an intergovernmental organization representing hydrography, established on June 21, 1921. The organization has around 98 Member States. The main purpose of the IHO is to ensure that the oceans, seas, and other navigable waters around the world are properly surveyed and charted. It sets international standards and promotes coordination between the world’s national hydrographic offices. The organization was earlier known as the International Hydrographic Bureau (IHB) but was later changed in 1970 to International Hydrographic Organization.
World Hydrography Day was established in 2005 by the IHO and adopted by the United Nations General Assembly in Resolution A/RES/60/30 Oceans and the law of the sea. June 21 was chosen as the day of celebration to mark the anniversary of the founding of the International Hydrographic Organization.
World Hydrography Day is observed by the IHO Member states and other national and international hydrographic organizations all over the world. Various activities such as awards ceremonies, conferences, seminars, workshops, lectures, and public events are organized all over the world to mark WHD. Individuals all around the world can take part in these lectures and workshops to celebrate World Hydrography day.
Every year the IHO Secretariat posts Member State and select stakeholder initiatives on the dedicated web page as well as on social media outlets. Advocates of hydrography are also invited to post on their own social media outlets and tag the IHO with hashtags #WorldHydrographyDay and #WHD.
