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. 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.

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)...

Normalized difference vegetation index (NDVI) is an indicator of vegetation health and density. High NDVI values generally correspond to dense vegetation and low NDVI values generally correspond to sparsely vegetated or barren areas. NDVI was calculated for pan-sharpened Landsat 8 Operational Land Imager images acquired on May 13, 2015 and May 15, 2016 for the region around Icy Bay, Alaska. NDVI results from 2015 were subtracted from results for 2016 to produce a change image. The change image can be used to assess changes in vegetation patterns resulting from a landslide that occurred near Tyndall Glacier in October, 2015 and generated a tsunami in Taan Fiord, an arm of Icy Bay. Positive change in NDVI generally...

This data release provides a gridded compilation of bathymetry data collected prior to the 2015 landslide in Taan Fiord, the northeast arm of Icy Bay, Alaska. The data release consists of a 50-m grid, derived from ten prior surveys covering both Taan Fiord and Icy Bay.
