World Hydrography Day is observed on the initiative of Monaco-based International Hydrographic Organization (IHO).

What is Hydrography?

Hydrography hels determining the depth of the water as well as the location of all navigational hazards such as wrecks and rocks on the seafloor. This is done primarily with specialised ships and boats equipped with echo sounders and sonars, but survey planes equipped with lasers are also used. Satellite observations can also provide useful information on occasion. The tides and currents are also measured in hydrography.
The most well-known application of hydrographic data is the creation of nautical charts, which are used by all mariners for navigation. Every human activity that takes place in, on, or beneath the sea requires hydrographic knowledge in order to be safe, efficient, and long-lasting.

World Hydrography Day 2022: Significance 

As per the website of the International Hydrographic Organization “The goal is to highlight how hydrography as an applied science supports the sustainable use of the oceans. This can include how up-to-date surveys and data can be used for initiatives for the protection of the marine environment, coastal zone management, marine protected areas, marine spatial data infrastructures, renewable energies, and all other components of the blue economy”.
