Abstract
|
In April of 2011 the National Geophysical Data Center (NGDC) an office of the National Oceanic and Atmospheric Administration (NOAA) developed two 1/3 arc-second Bathymetric-topographic digital elevation models (DEMs) centered on Elfin Cove, Alaska. The DEMs were developed for the Pacific Marine Environmental Laboratory (PMEL) and will also be used forthe National Tsunami Hazard Mitigation Program (NTHMP; http://ntmp.tsunami.gov) 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 DEMs were built at 1/3 arc-second and an 8/15 arc-second empty xy ascii file was filled using the 1/3 arc-second DEM for use by UAF. The coastal DEMs will be used as input for the university-developed modeling system to simulate tsunami generation, propagation, and inundation (http://www.aeic. alaska.edu/tsunami/). The DEMs were generated from diverse digital datasets in the region (grid sources shown in Fig. 5) and was designed to represent modern morphology. This report provides a summary of the data sources and methodology used to develop the Elfin Cove DEMs.
