Answer 2

Answer:

The primary use of hydrography is the creation of nautical charts. Nautical charts are maps of the ocean. They depict water depths, obstructions, and any other information a ship might need to safely navigate. Without nautical charts, sailing would be much more dangerous and expensive. This is important because ships are the backbone of overseas trade. Nearly 80% of the United States overseas trade is conducted through marine transportation.  However, hydrography is used for much more than just the creation of nautical charts. Among other uses, hydrography has been used to chart and manage oyster beds, identify wrecks, help economies recover after hurricanes, assist in the preservation of coral reefs, locate damaged pipelines underwater, and monitor the foundation of ocean wind turbines.
