World Hydrography Day 2021

World Hydrography Day is observed every year on 21 June. The day highlights the importance of hydrography and its relevance. This important day was approved and implemented by the International Hydrographic Organization (IHO) as an annual celebration.

This year, the IHO is also celebrating the 100th anniversary of its formation.

Hydrography is the measuring and characterization of the physical features of oceans, seas, coastal regions, lakes, and rivers. Apart from this, it forecasts their change with time for the primary goal of navigation safety and to help all other maritime operations.

The main objective of World Hydrography Day is to attract people’s attention to the work of the IHO at the international level. It is also celebrated to urge countries to work together to protect the marine environment and seek safe international navigation around the world.
