Description:

Abstract:

This data release contains 35 multichannel sparker and 24 multichannel minisparker seismic reflection (MCS) profiles that were collected in November of 2014 from the Catalina and Santa Cruz Basins offshore southern California by the U.S. Geological Survey Pacific and Coastal Marine Science Center. Data were collected aboard the University of California’s R/V Robert Gordon Sproul on USGS cruise 2014-645-FA. MCS profiles were collected to assess earthquake and submarine landslide hazards offshore southern California.

Purpose:

Data were acquired to support USGS geologic hazards projects to aide hazard assessment and geologic structure mapping of southern California’s offshore Catalina, Catalina Ridge, San Clemente, and San Diego Trough Fault Zones. These data were collected to update the USGS Quaternary fault database and shaking hazard models developed by the Working Group on California Earthquake Probabilities. In addition, the survey imaged a large landslide complex in Santa Cruz Basin in order to determine causes and age of seafloor failure. Data collection was funded in part by UC Student Ship Funds. Chirp sub-bottom data were collected coincidentally. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.

Attribute_Accuracy:

Attribute_Accuracy_Report: Identified as the best available version

Logical_Consistency_Report:

Multichannel seismic-reflection data were collected during USGS field activity 2014-645-FA using a 5kJ Delta sparker source for lines 1-17 and a 700J SIG-2mile minisparker source for lines 18-40. MCS data were recorded with a Geometrics 48-channel, 300-meter digital streamer. Depth control birds were used to fly the streamer at consistent depths below the sea surface. Quality control was conducted during the collection process.

Completeness_Report:

Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Position data were provided by a Differential Global Positioning System (DGPS) navigation receiver. A formal accuracy assessment of the horizontal positional information in the data set has not been conducted.

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.

Process_Step:

Process_Description:

Seismic-reflection profiles were collected during USGS field activity 2014-645-FA using a 5kJ Delta sparker source or a 700J Joule minisparker source and recorded with a 300-meter, 48-channel Geometrics digital seismic streamer with 6.25m group spacing.

Process_Date: 20141125

Process_Step:

Process_Description:

MCS profiles were processed using SIOSEIS and Seismic Unix. SIOSEIS processing included conversion from SEGD to SEGY, geometry calculation using navigation, 20-1000Hz bandpass filter and CDP gather sorting. Seismic Unix processing included channel rejection, zerophase bandpass filtering, de-spike, butterworth minimum phase filter, NMO correction, DMO correction, pre-stak Stolt migration of CDP gathers, trace balancing, predictive deconvolution, trace mix, and AGC. Navigation was converted to UTM zone 11N and smoothed over 50m using a local regression algorithm in MatLab. Note that the repeating navigation at the beginning of each line is an artifact of the navigation smoothing and doesn’t affect the overall positional accuracy of the dataset.
