NOAA's Office of Coast Survey ensures safe, efficient and environmentally sound marine transportation that brings an uninterrupted flow of people and goods into and out of our nation's ports.

Since President Thomas Jefferson asked for a survey of the coast in 1807, Coast Survey has been the nation’s trusted source for nautical charts covering the coastal waters of the U.S. and its territories.

Today's Coast Survey produces the navigational products, data, and services to move commerce and protect life and property at sea.
