    • Multichannel minisparker data of USGS field activity 2017-612-FA collected in Puget Sound, Washington in February of 2017

    Metadata Updated: January 21, 2026

    High-resolution multichannel minisparker seismic-reflection data were collected by the U.S. Geological Survey and the University of Washington in February of 2017 west of Seattle in Puget Sound and in Lake Washington, Washington. Data were collected aboard University of Washington’s R/V Clifford A. Barnes during USGS field activity 2017-612-FA using a 500 Joule SIG 2-mille minisparker sound source and recorded on a 48 channel Geometrics digital hydrophone streamer. Sub-bottom acoustic penetration spans several hundreds of meters and is variable by location.
