Summary

High-resolution acoustic backscatter data were collected by the U.S. Geological Survey (USGS) and the Alaska Department of Fish and Game in May of 2014 southwest of Chenega Island, Alaska. Data were collected aboard the Alaska Department of Fish and Game vessel, R/V Solstice, during USGS field activity 2014-622-FA, using a pole mounted 100-kHz Reson 7111 multibeam echosounder.

Purpose

This work was funded by the U.S. Geological Survey (USGS) Coastal and Marine Hazards and Resources Program (CMHRP) Marine Geohazards Project and the Alaska Department of Fish and Game (ADFG). The high-resolution bathymetry of bedrock, sediment deposits, and tectonic structure provide geologic information that is essential to hazard assessment, regional sediment management, 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. These data and information are intended for science researchers, students from elementary through college, policy makers, and the general public.
