World Hydrography Day

World Hydrography Day, June 21st, emphasizes the importance of surveying and charting bodies of water. The day also encourages the general public to learn more about hydrograph science.

It's a known fact that 75% of the earth is covered with water. Although the majority of the earth's water is found in oceans, rivers, swamps, glaciers, and aquifers, the majority of the water is also found in lakes, rivers, swamps, glaciers, and aquifers. Water vapor is also present in the air. Water is important for a variety of reasons. Humans and animals would not survive without water, humans, and animals. We also use water for irrigating crops, keeping the environment clean, and providing recreational opportunities.

Water also plays a vital role in transportation. Scientists find out specific details about how to navigate the earth's waterways. This information helps ships and other vessels navigate the waters safely and efficiently. This falls under the science of hydrography. The following links are included in the study: The information these scientists are looking for includes: The following links are links to the following: The details that these scientists are looking for include:

Water depth
The seafloor and coastline are shaped by the seafloor and coastline
Possible obstructions can be found in the exact location of potential obstructions
Water bodies' physical characteristics Water bodies' physical characteristics Water bodies' physical characteristics

Scientists use all of this data to create nautical charts. These charts cover 95,000 miles of shoreline. In addition, the charts cover 3.6 million square nautical miles of waters in the United States alone. Hydrography also helps in other areas, such as transportation and navigation. These include seafloor construction, anchoring, recognizing fish habitats, and laying pipelines and cables.

#WorldHydrographyDay is a hashtag that people use on social media.

The world hydrography day is the first in history

In 2005, the IHO established World Hydrography Day. The United Nations General Assembly passed a resolution in the same year that recognized the establishment of this day. The date of June 21st coincides with the founding of the IHO in 1921 under the name International Hydrographic Bureau. In 1970, the IHO was changed to the IHO.

This day's theme has included: The following are past themes for this day:

2021: One hundred years of international cooperation in hydrography, 2021.

Hydrography is enabling autonomous technologies in 2020, according to Hydrography.

2019: Hydrographic evidence fueling marine research.

Bathymetry – the foundation for healthy seas, oceans, and waterways in 2018.

2017: Mapping our oceans, oceans, and waterways – more important than ever.
