World Hydrography Day 21 June 2015
On 21st June each year the International Hydrographic Organization (IHO) celebrates World Hydrography Day.
World Hydrography Day is the opportunity to increase public awareness of the vital role that hydrography plays in
everyone’s life. The theme for this year’s World Hydrography Day, which is also the 94th anniversary of the establishment of the IHO, is:
“Our seas and waterways - yet to be fully charted and explored”
On 29th November 2005, the United Nations adopted Resolution A/60/30, that includes the statement:
"Welcomes the adoption by the International Hydrographic Organization of the World Hydrography Day, to be celebrated annually on 21 June, with the aim of giving suitable publicity to its work at all level and of increasing the coverage of hydrographic information on a global basis, and urges all States to work with that organization to promote safe navigation, especially in the areas of international navigation, ports and where there are vulnerable or protected marine areas."
The theme for World Hydrography Day 2015 concentrates on the fact that much of the world’s seas, oceans and navigable waters remain unsurveyed and is intended to raise public awareness that, for example, there are higher resolution maps of the Moon and Mars than for many parts of our seas and coastal waters.
This year’s theme also provides the opportunity to encourage innovative supplementary data gathering initiatives to help obtain more useful depth data. This includes crowd-sourcing using existing ships and ship’s equipment, and developments in the analysis of satellite imagery in areas where the water is clear enough.
These methods cannot replace highly accurate and thorough hydrographic surveys using specialist ships and equipment, but they can provide useful depth information where otherwise we have none.
The role of the world’s hydrographers.
Hydrographers work in both the public and private sector. Government hydrographers are usually involved in surveying to improve nautical charts and for defence and security purposes as well as to provide qualified base data for maritime geospatial information systems (GIS). Commercial hydrographers are more often involved in specialized tasks including high resolution surveys for undersea pipelines and cables, the installation of offshore structures including wind farms, oil and gas platforms and surveys for new ports and harbours. They also do surveys under contract to governments to improve nautical charts.
Hydrographers use Hydrographic Sensors such as echo sounders, high definition sonars in boats and ships, lasers from aircraft and sometimes satellite images to obtain precise and accurate measurement. They also need to be experts in precise positioning and in the measurement of currents and tides.
