Description:
Abstract:
This processed high-resolution sparker seismic-reflection (Seismic) data for the Offshore of Eureka, California, map area is part of USGS Data Series 781 (Golden and Cochrane, 2019). The map area is one of 83 map areas of the California State Waters Map Series. The data were collected aboard Humboldt State University’s R/V Coral Sea in 2009 on U.S. Geological Survey cruise C109NC on the shelf between Cape Blanco, Oregon, and Cape Mendocino, California. Seismic data were collected to characterize quaternary deformation and sediment dynamics on the continental shelf offshore of Humboldt Bay.
Purpose:
The USGS collected high-resolution sparker Seismic profiles in 2009 in California State waters from the northern California State boundary to the northern edge of Cape Mendocino, California. Primary goals of this survey were to image the offshore portion of the Quaternary unconsolidated sediment. Other goals were to image the any recent fault offsetting of sedimentary units. Seismic data were collected using a Delta Sparker source and recorded on a digital streamer. These data and information are intended for science researchers, students, policy makers, and general public.
