The National Ocean Service (NOS) has been charged with producing tidal current tables for the coastal areas of the United States. Tidal currents are almost always the strongest current experienced by vessels operating offshore and for cons iderable distances inside of bays and river estuaries. Tidal currents are usually fastest where water level fluctuations on wide continental shelfs are amplified as they approach the coast and water is forced through a narrow constricted channel into a large bay or estuary. Knowledge of the timing and strength of tidal currents is extremely important for safe navigation in coastal waters. Mariners are primarily interested in the timing and strength of four phases of the tidal current cycle which are printed in the NOS Tidal Current Tables. These phases are slack before flood (SBF), maximum flood current (MFC), slack before ebb (SBE), and maximum ebb current (MEC). Two other phases are also included in the NOS Tidal Current Tables. .....
