Celebrated every year on 21 June, it highlights the importance of hydrography and why it is still relevant.
This year’s theme, as proposed by the International Hydrographic Organization (IHO) is :
One hundred years of international cooperation in hydrography
The theme is designed to showcase progress in knowledge and technology over the past 100 years, while celebrating the ground-breaking work which was done during this period. The goal is to highlight the past, present, and future of hydrography by showing the important work of early hydrographers, progress in technology, and state of the art in technology.
