World Hydrography Day

World Hydrography Day

World Hydrography Day is a great chance to increase public awareness of hydrography science. As a global leader in this growing field, the Canadian Hydrographic Service creates the nautical charts that mariners rely on for safe navigation.

The International Hydrographic Organization (IHO) and its international members celebrate World Hydrography Day every year on June 21. The theme for 2019 is “hydrographic information driving marine knowledge,” reflecting the increasing importance of hydrographic information to the broader marine community. Hydrographic surveying not only supports nautical charting and the delivery of tide, current and water level information but also safe maritime transportation, marine conservation, determining the limits of Canada’s continental shelf, and so much more.

As a proud member of IHO, Canada has participated in this global event since it started in 2005. This year’s celebration is especially important as it marks the 100th anniversary of the first International Hydrographic Conference, held in London in 1919, leading to the foundation of the modern IHO.
