These data were acquired in 2006 using the Research Vessel Sea Explorer (USGS Field Activity ID: S-2-06-SC). The data are available in binary, TIFF and JPEG image formats. Binary data are in Society of Exploration Geologists (SEG) SEG-Y format and may be downloaded for further processing or display. Reference maps and JPEG images of the profiles may be viewed with your Web browser. Purpose: In September 2008, the U.S. Geological Survey (USGS) collected seismic-reflection in an area from as far north as Laguna Beach, Orange County, CA to offshore of Oceanside, San Diego County, CA (cruise S-2-06-SC, Figure 1). Reflection profiles were located to provide information on the geometric representations of offshore faults and recency of fault activity. The profiles were primarily oriented perpendicular to the shore (NE-SW) in waters depths from mid-shelf to the base of the slope. Data acquisition focused on the imaging of blind thrust faults and folds that had been proposed to lie beneath much of offshore Orange and San Diego Counties (the Oceanside fault) and the offshore Newport-Inglewood fault zone. Supplemental_Information: Mini-sparker profiles are collected with a 500 Joule sparker source and 15-m single-channel streamer towed at the sea surface. The acoustic energy is reflected at density boundaries (such as the sea floor or sediment layers beneath the sea floor), and detected by the hydrophone array, and digitally recorded by the onboard PC-based acquisition system. As the vessel moves, this process is repeated multiple times per second, producing a two-dimensional image of the shallow geologic structure beneath the ship track. Additional information about the USGS field activity S-2-06-SC is available at .

All seismic-reflection data collected on the referenced cruises have been included in this report. Some seismic profiles have gaps in them due to system crashes, mammal shutdowns or hardware maintenance. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Shot point numbers in the data files correspond to those in the navigation files. The horizontal positional accuracy of the seismic data thus linked to ship's position is estimated to be within 30 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Depths shown in the seismic data files are in milliseconds (round trip travel time) and are referenced to sea level.
