    • Multichannel sparker seismic reflection data collected during USGS field activity 2018-658-FA between Cape Blanco and Cape Mendocino in October of 2018

    Metadata Updated: January 22, 2026

    This data release contains processed high-resolution multichannel sparker seismic-reflection (MCS) data that were collected aboard Humboldt State University’s R/V Coral Sea in October of 2018 on U.S. Geological Survey cruise 2018-658-FA on the shelf and slope between Cape Blanco, Oregon, and Cape Mendocino, California. MCS data were collected to characterize quaternary deformation and sediment dynamics along the southern Cascadia margin. MCS data were collected coincidentally with chirp sub-bottom data.
