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) of Kachemak Bay, Alaska. The 1/3 arc-second DEM, referenced to Mean High Water (MHW), was developed and evaluated using diverse digital datasets available for the region. The DEM will be used as input for the Method of Splitting Tsunami (MOST) model developed by the Pacific Marine Environmental Laboratory (PMEL) NOAA Center for Tsunami Research (http://nctr.pmel.noaa.gov/) to simulate tsunami generation, propagation and inudation as part of the tsunami forecast system. Short-term Inundation Forecasting for Tsunamis (SIFT) is currently being developed by PMEL for the NOAA Tsunami Warning Centers. This report provides a summary of the data sources and methodology used in developing the Kachemak Bay DEM.
