Summary

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.

Purpose

The USGS collected high-resolution sparker MCS profiles in October of 2018 along the southern Cascadia margin and marine forearc between Cape Blanco, Oregon, and Cape Mendocino, California. Primary goals of this survey were to image the offshore portion of the Quaternary active Little Salmon and Mad River fault zones. Other goals were to image the stratigraphy of Trinidad, Sixes, and Rogue canyons. MCS data were collected using a Delta Sparker source and recorded on an 88-channel digital streamer. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.
