Sonic velocity and density well logs in the Central Coast Ranges in California were digitized by hand. These logs are available as scanned files (pdfs and tiffs) on the California Division of Oil, Gas, and Geothermal Resources website and the data consist of interval transit times and bulk density measured downhole in oil and gas wells in the region. Sonic velocity data were also compiled from a number of sources. A summary table provides basic information of these wells, available on the California Division of Oil, Gas, and Geothermal Resources website.

This data release contains deep seismic reflection profiles CC-1 and CC-2, which extend eastward from within the California Coast Ranges across the Great Valley and into the Sierran foothills, with a combined east-west length of about 140 km at about the latitude of the town of Merced (37.25° north latitude). The records are processed to 15 seconds two-way time and thus extend deep into the lithosphere as well as capturing detail in the shallow crust. Field data (no longer available) were collected in 1982-85 with vibrator source, an 800-channel, split-spread receiver array using SIGN-BIT technology, and a maximum offset of 12.2 km. Line CC-1 extends from Franciscan Complex of the eastern Coast Ranges east to Merced...
