Descripción:
Tide and water level datums are standard elevations used to reference water level heights and depths. Each type of datum represents a unique phase or behavior of the water along the coast or in the Great Lakes. CO-OPS and its partners are currently in the midst of two large-scale datum updates for the National Tidal Datum Epoch (NTDE) and the International Great Lakes Datum (IGLD). This video explains what the NTDE is, along with the importance and application of tidal datums for marine commerce, environmental restoration, and coastal resilience. You can learn more at https://tidesandcurrents.noaa.gov/datum-updates/.

- Explain what the National Tidal Datums Epoch (NTDE) is.
- Describe the work required to update the NTDE.
- Recall the length of record required to calculate a new NTDE and why that is so.
- Describe the importance and application of tidal datums for marine commerce, environmental restoration, and coastal resilience.
