Abstract The National Geophysical Data Center (NGDC), an Office of the National Oceanic and Atmospheric Administration (NOAA), has developed a bathymetric-topographic digital elevation model (DEM) centered on Tatitlek, Alaska. The DEM was developed for the National Tsunami Hazard Mitigation Program (NTHMP; in support of the State of Alaska's tsunami inundation modeling efforts led by the Geophysical Institute at the University of Alaska at Fairbanks (UAF). The 8/15 arc-second DEM is nested within the extents of the previously developed Prince William Sound 8 arc-second and 8/3 arc-second DEMs. Thecoastal DEM will be used as input for the university-developed modeling system to simulate tsunami generation, propagation, and inundation (http//www.aeic. The DEM was generated from diversedigital datasets in the region and was designed to represent modern morphology. Primary data sources and grid development methology are described in the technical report for the Prince William Sound DEMs. Additional datasets used in developing the Tatitlek DEM are described inthis report, which provides a summary of the supplemental data sources and quality control procedures used in developing the Tatitlek DEM.
