Deep (15-second) seismic reflection profiles CC-1 and CC-2 extending from the eastern California Coast Ranges across the Great Valley into the Sierran foothills at about latitude 37.25 Degrees N

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 in the Great Valley; [...]
