- 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.
