- Alaska Tidal Datum Portal
- For Alaska's coastal communities, an understanding and awareness of local tidal datums is critical to assessing vulnerability and planning responses to coastal geohazards. The Alaska Tidal Datum Portal is provided by DGGS staff to assist users with: answers to common questions about tidal datums, tidal datum calculations, and links to additional information and authoritative data sources.
The links on this page are provided as a courtesy to help our users find Alaskan geology-related information. Links are limited to publicly funded or non-profit organizations; administrative regulations prohibit links to commercial organizations.
