Terrain model for Icy Bay, Alaska with slip surface for 2015 landslide

This digital terrain model of the Icy Bay, Alaska region consists of elevations acquired using airborne Interferometric Synthetic Aperture Radar (IFSAR) merged with bathymetry interpolated from various hydrographic surveys and inferred landslide slip surface elevations for a landslide that occurred on October 17, 2015 near the terminus of Tyndall Glacier. Hydrographic information for Icy Bay and the lower 9 km of Taan Fiord was primarily from hydrographic surveys and a nautical chart published by the U.S. National Oceanic and Atmospheric Administration (NOAA). Near the head of Taan Fiord, hydrographic survey points were from Meigs and others (2006). The reach of Taan Fiord between the study of Meigs and others (2006) and the NOAA hydrographic data was interpolated using manually drawn contours. In the source area of the October 17, 2015 landslide, land surface elevations were replaced with inferred elevations of the surface on which the landslide moved (slip surface). The slip surface produces a displaced material volume of 73 million cubic meters.
