Maintained by NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS), the National Tidal Datum Epoch (NTDE) is the collection of water level observations over a 19-year period to generate a set of tidal datums. NTDE incorporates data from 2,000+ coastal water level stations. Updating this reference period will ensure the nation’s tidal datums are based on recent data and provides a common reference frame to account for long-term effects of land movement, sea level rise and changes in tidal constituents. Accurate tidal datums are critical for federal, state, and private-sector coastal zone activities, including navigation, storm warning, and marine boundary determination.

After 2026, CO-OPS will replace the existing 1983-2001 NTDE. The new 2002-2020 NTDE will include the CO-OPS repository of permanent real-time and historic stations with available data. New datum automation procedures will generate new NTDE products more efficiently to deliver the update on schedule.
