What’s happening in the world of NTDE?

The NTDE (2002-2020) update represents a significant, multi-year undertaking for CO-OPS. As part of the update, CO-OPS will update nearly 2,000 tidal datums and bench mark sheets. These products will be provided to users at the end of the update in one seamless release.

CO-OPS will regularly publish news stories about the NTDE update. You can access these stories on the right or via our CO-OPS news page. Check back periodically for more stories or subscribe to our NTDE (2020) email alerts by sending us an email at navigationnews@noaa.gov. Our email alerts are periodically generated and will contain the latest information about ongoing NTDE efforts.
