Description:
Abstract:
Multichannel minisparker and boomer seismic-reflection data were collected by the U.S. Geological Survey in September of 2013 in Port Valdez, Alaska. Data were collected aboard the USGS R/V Alaskan Gyre during field activity G-01-13-GA, using a 500-Joule SIG 2-mille minisparker or an Applied Acoustics triple plated S-Boomer sound source and a 24-channel Goemetrics hydrophone streamer. Sub-bottom acoustic penetration spans several hundreds of meters and is variable by location.
Purpose:
High-resolution multichannel seismic-reflection data were acquired to support the U.S. Geological Survey Alaska coastal and marine hazards project to explore the sedimentary structure of tsunamigenic landslide deposits around an IODP drill site in Port Valdez. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.
