World Hydrography Day is celebrated annually on the 21st of June to raise awareness about the importance of hydrography in promoting safe navigation, sustainable development, and environmental protection. Hydrography, the science of measuring and mapping water bodies, plays a vital role in ensuring the safety of maritime transportation, managing marine resources, and preserving the health of our oceans and coastal areas.

Ensuring Safe Navigation:

  • Nautical charts and bathymetric data: Hydrographic surveys provide accurate and up-to-date information on water depths, underwater obstructions, and coastal features. Nautical charts created based on this data assist mariners in navigating safely and avoiding potential hazards.

  • Navigational aids and services: Hydrographic organizations maintain and deploy aids to navigation such as buoys, beacons, and lighthouses. They also provide navigation services like issuing navigational warnings, tide predictions, and current information to support safe ship movements.

Managing Marine Resources:

  • Resource exploration and exploitation: Hydrographic surveys help in identifying and mapping potential offshore resources such as oil, gas, minerals, and renewable energy sites. Accurate data on seabed characteristics and bathymetry assist in responsible resource exploration and sustainable exploitation.

  • Fisheries management: Hydrography aids in understanding the marine environment, including fish habitats, migration routes, and spawning grounds. This information is crucial for implementing effective fisheries management measures, ensuring the sustainability of fish stocks, and supporting the livelihoods of coastal communities.

Protecting the Marine Environment:

  • Coastal zone management: Hydrographic surveys provide valuable data for coastal zone planning, erosion control, and land-sea interaction studies. Understanding the dynamics of coastal areas helps in implementing measures to protect fragile ecosystems and mitigate the impacts of climate change.

  • Marine conservation: Hydrography contributes to the identification and protection of marine protected areas, critical habitats, and biodiversity hotspots. By mapping sensitive areas and monitoring changes over time, hydrographic organizations support conservation efforts and ecosystem preservation.

International Cooperation and Technological Advances:

  • International Hydrographic Organization (IHO): The IHO promotes international cooperation among hydrographic organizations, establishing standards and guidelines for hydrographic surveys, data exchange, and nautical chart production. It fosters collaboration and knowledge sharing to enhance safety at sea and sustainable maritime development.

  • Technological advancements: Hydrography has benefited from technological innovations such as multibeam and side-scan sonar systems, satellite imagery, and autonomous survey platforms. These tools enable faster and more accurate data collection, enhancing the efficiency and effectiveness of hydrographic operations.


World Hydrography Day serves as a reminder of the critical role played by hydrography in ensuring safe navigation, managing marine resources, and protecting the marine environment. By promoting awareness and cooperation among hydrographic organizations, we can strive for safer seas, sustainable development, and the preservation of our invaluable oceans for future generations. Let us recognize the significance of hydrography and support the efforts to maintain the health and productivity of our marine ecosystems.
