World Hydrography Day 2023
Tags: Important Days
World Hydrography Day is an annual celebration held on June 21st to raise awareness about hydrography and its significance.
An overview of the news
The primary objective of hydrography is to measure water depth and identify navigational hazards such as wrecks and rocks.
This is accomplished through various methods, including the use of specialized boats with echo sounders and sonars, laser-equipped survey aircraft, and satellite observations.
Theme of 2023
The theme for World Hydrography Day 2023 is "Hydrography – underpinning the digital twin of the ocean."
This theme emphasizes the interconnectedness of hydrography and oceanography in creating a virtual representation of the ocean known as the "digital twin."
Background of the day
It was established by the International Hydrographic Organization (IHO) to highlight the importance of hydrography in marine conservation and safe navigation.
The concept of World Hydrography Day was proposed by the IHO in 2005, and it was officially adopted by the UN General Assembly through Resolution A/RES/60/30 Oceans and the Law of the Sea.
What is Hydrography?
Hydrography also involves the calculation of tides and currents in oceans and seas.
It is considered an applied science that supports navigation safety, economic growth, security and defense, scientific research, and the understanding of ocean physics.
