NOAA's National Ocean Service produces nautical charts that contain information about the nature and form of the coast, the depths of the water and general character and configuration of the sea bottom, locations of dangers to navigation, the rise and fall of the tides, locations of navigation aids, and characteristics of the earth's magnetism. To learn more about nautical charts, follow the Office of Coast Survey link below.
NCL maintains a large collection of NOAA nautical charts, both current and past editions from about 1993 when it became a Federal Depository Library. The library also recently acquired earlier editions of some Pacific and Atlantic coast nautical charts published in 1969 by one of NOAA's predecessor agences - U.S. Coast and Geodetic Survey.
Nautical charts are accessed by five digit number as found in the Nautical Chart Catalog. (Exceptions to this five digit number are chart numbers 50, 411, 500, 501, 530, and 531). You can access the Nautical Chart Catalog online via the Office of Coast Survey website. Once you have the chart number you can check its availability at NCL using the catalog record for NOAA nautical charts [Nautical chart, C 55.418/7: ]. Contact the reference desk if you cannot find the chart you need. You can also view charts via the Office of Coast Survey's interactive catalog (linked below).
Dates of Latest Editions: NOS Nautical Charts & Misc. Maps is an important tool that helps identify current editions of nautical charts. Charts with edition dates prior to those listed in this publication are obsolete for use in navigation. The charts are listed by number, so you have to consult chart catalogs to identify chart titles you need.
