Theme of the World Hydrography Day (WHD) 2022 was “Hydrography — contributing to the United Nations Ocean Decade”. The event was celebrated by PNHD on 21 June 22 to highlight the relevant contributions of hydrography as a discipline of applied sciences to the United Nations Decade of Ocean Sciences for sustainable development (2021-2030). This year World Hydrography Day celebrations highlighted the efforts to bring together ocean actors across the world to foster the partnership and generate the knowledge needed to support a well-functioning, productive, resilient, sustainable and inspiring ocean. Pakistan is a responsible coastal state blessed with over 1000 kms of coastline and around 290,000 Sq. Km of sea area. More than 90% of Pakistan's trade by volume and 70% by value are carried out through Arabian Sea. Pakistan is also responsible for hydrographic surveys and production of nautical carts/ maps of its waters to provide accurate nautical information to mariners. Pakistan Navy Hydrographic Department (PNHD), on behalf of Pakistan, is fulfilling this responsibility. Pakistan Navy celebrates this day every year to underscore the importance of hydrography towards its share in all marine and maritime related activities. Pakistan Navy is ever ready to continuously contribute towards activities and supporting various aspects of blue economy which are eventually contributing towards our national economy.
