The Notes on the Coast of the United States are a series of eight memoirs written in 1861 by the "Blockade Strategy Board." The Board included among its members the Superintendent of the U.S. Coast Survey, A.D. Bache. Superintendent Bache saw the Board as a means of continuing the important work of the Coast Survey in the midst of the Civil War. The surveys completed by Bache and his team include sailing directions and detailed geographic information for the Southeast and Gulf Coasts. The documents were instrumental to Union Army and Navy operations, as officers planned blockade strategy using field correspondence from the Board.

Currently, nine of these charts, listed below, have been scanned and added to NOAA's Historical Chart Collection. The Office of Coast Survey plans to make the entire Notes on the Coast chart collection available in the near future.
