Multichannel sparker seismic reflection data of USGS field activity 2018-658-FA collected between Cape Blanco and Cape Mendocino from 2018-10-04 to 2018-10-18

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.

Geologic map of the Cape Mendocino, Eureka, Garberville,and southwestern part of the Hayfork 30 X 60 Quadrangles and Adjacent OffshoreArea, Northern California

This digital map database, compiled from previously published andunpublished data, and new mapping by the authors, represents thegeneral distribution of bedrock and surficial deposits in themapped area. Together with the accompanying text file (ceghmf.ps,ceghmf.pdf, ceghmf.txt), it provides current information on thegeologic structure and stratigraphy of the area covered. Thedatabase delineates map units that are identified by general ageand lithology following the stratigraphic nomenclature of the U.S.Geological Survey. The scale of the source maps limits the spatialresolution (scale) of the database to 1:100,000 or smaller.
