World Hydrography Day is observed globally on 21st June every year. This day was adopted by the International Hydrographic Organization (IHO) as an annual celebration to publicise the work of hydrographers and the importance of hydrography. It is designed to raise awareness about hydrography and how it plays a role in improved knowledge of the seas and oceans.
“Hydrography – Underpinning the Digital Twin of the Ocean”
With this World Hydrography Day 2023’s theme, the digital twin of the ocean aims to develop a consistent, high-resolution, multidimensional and near real-time virtual representation of the ocean that could make ocean knowledge open-access, available to citizens, scientists and policy-makers around the world, and will provide a platform for global cooperation. The theme for WHD is designed to highlight the relationship between hydrography and oceanography, and how hydrography can play a key role in developing the digital twin of the ocean.
