The U.S. Geological Survey (USGS) collected high-resolution seismic-reflection profiles in August 2016 in the Gulf of Alaska, between Icy Point and Dixon Entrance. The survey was designed to map the Queen Charlotte-Fairweather Fault zone that extends along the southeast Alaska continental margin. This work was funded by the USGS Coastal and Marine Geology Program‚ Marine Geohazards Project. These high-resolution seismic-reflection profiles image the shallow structure and stratigraphy along the Queen Charlotte-Fairweather Fault system. This data can be used to better understand its deformation history and the interplay between Quaternary deformation and sedimentary processes. This geologic information is essential to hazard assessment and coastal and marine spatial planning at Federal, State and local levels, as well as to future research on the geomorphic, sedimentary, tectonic and climatic record of southeastern Alaska.
