These are the 2016 or 2017 editions of the classic tidal current tables that mariners have depended on since they were first introduced by the Coast and Geodetic Survey in 1890. Formerly published by the National Ocean Service (NOS), a division of National Oceanic & Atmospheric Administration (NOAA). In recent years, NOAA made these tables available to the public, but they are no longer printed by the government. Included are the times and velocities of ebb and flood currents, information on rotary currents, Gulf Stream information, and data on thousands of locations in North America, South America, and Asia. All tables are unaltered & unabridged.
Like the companion Tide Tables, these are 8 ½" x 11" and easy to read.
