World Hydrography Day 2020 Theme

World Hydrography Day is an annual celebration observed on every 21st of June to publicizes the work of hydrographers and the importance of hydrography. This day was adopted by the International Hydrographic Organization (IHO) to Highlights the importance of hydrography, particularly in the conservation of marine reserves and also in promoting safe navigation in foreign waters and ports. In 2005 the International Hydrographic Organization (IHO) proposed the concept to celebrate World Hydrography Day and in 2005 the UN General Assembly (UNGA) has officially adopted a Resolution A / RES/60/30 Oceans and the Law of the Sea.

What is Hydrography?

Hydrography is the measurement of water depth and positionings of all navigational hazards, such as wrecks and rocks. These are mainly done by specialized boats operating echo sounds and sonars, but also by means of laser-equipped survey aviation. Sometimes useful information can also be gathered from observations by satellite. Hydrography also calculates the tide and current in the sea and oceans.

Hydrography is an applied science, which focuses on the calculation and definition, for the primary purposes of the protection of navigation and in support of all other maritime activities including economic growth, security and defense, scientific studies, and other physics of the oceans, seas, coasts, rivers, lakes, and rivers.

Theme of World Hydrography Day 2020

This year the theme of World Hydrography Day 2020 is- “Hydrography – enabling autonomous technologies”.

The Member States of the International Hydrographic Organization decide a theme for each World Hydrography Day to promote the importance of international hydrography, multilateral cooperation, and effective collaboration in data exchange, charting, and development of standards.

The goal of the 2020 World Hydrography Day theme is to provide a sufficient range of opportunities for publication of work and hydrographic services by national hydrographic agencies, stakeholders of the industry, expert contributors, and the scientific community.

The theme underlines the main role of autonomous technology hydrography. The use of autonomous platforms (ASVs, AUVs) and Lidar-equipped aerial vehicles (UAVs) for conducting hydrographical surveys can be done on autonomous platforms, as are the case with drones. A testing ground for these technologies is provided by hydrography while increasing the area coverage. These initiatives will knock-on effect and open up the way towards developing safe, safe , environmentally sound, Maritime Autonomous Surface Ships (MASS), operations that also require certified hydrographical information to be carried out under the auspices of the International Maritime Organization (IMO).

This year theme will focus on the key role that hydrography can play in support of autonomous technologies which includes  surface and underwater survey drones, aerial as well as autonomous ships.

Autonomous technologies are not new technologies, from decades mariners have been using devices like autopilots. In recent times unmanned vessels such as wave gliders helped to make progress in the ocean sciences. Yet we are seeing an increase in flexibility and broader application. Countries like Norway are actively running self-contained ferries trials.
