NOAA/NCEI 10-m Bathymetry: USMOI: Wake Island

Published by Pacific Islands Ocean Observing System (PacIOOS) | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2015-07-30T00:00:00.000+00:00
A 10-m (1/3 arc-second) resolution gridded digital elevation model (DEM) for the bathymetry (ocean depth) surrounding Wake Island in the Central Pacific Ocean, one of the U.S. Minor Outlying Islands (USMOI). It covers the three low coral islands--Peale, Wake, and Wilkes--that make up the island, and extends onto the slopes of its volcanic pedestal. It is referenced to a vertical tidal datum of Mean High Water (MHW) and was compiled from various data sources including: NOAA National Centers for Environmental Information (NCEI), formerly the National Geophysical Data Center (NGDC); the U.S. National Ocean Service (NOS), the U.S. Geological Survey (USGS), the U.S. Army Corps of Engineers (USACE), the Federal Emergency Management Agency (FEMA), and other federal, state, and local government agencies, academic institutions, and private companies. Developed for the National Tsunami Hazard Mitigation Program (NTHMP) to support NOAA's tsunami forecasting and modeling efforts. Not to be used for navigational purposes.
