Description:

Abstract:

High-resolution multichannel minisparker seismic-reflection data were collected by the U.S. Geological Survey in July of 2018 between Point Conception and Coal Oil Point in the Santa Barbara Channel, California. Data were collected aboard the USGS R/V Parke Snavely during field activity 2018-645-FA, using SIG 2-mille minisparker and recorded using an 8-channel Geometrics digital hydrophone streamer. Sub-bottom acoustic penetration spans several hundreds of meters and is variable by location.

Purpose:

Data were acquired to support the USGS geologic hazards projects to aide hazard assessment of shallow faulting, slope stability, and submarine landslides along the western Santa Barbara Channel. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.

Supplemental_Information:

Additional information about the field activities from which these data were derived is available online at:

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report: Identified as best available version

Logical_Consistency_Report:

No formal logical accuracy tests were conducted, but quality control was conducted during data acquisition.

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:

Estimated to be no less than 3m due to total propagated uncertainties of navigation as well as data processing.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

A formal accuracy assessment of the vertical positional information in the data set has not been conducted.

Process_Step:

Process_Description:

Multichannel minisparker seismic-reflection data were collected using a 500-Joule SIG 2-mille minisparker sound source and recorded using an 8-channel, 25-meter Geometrics digital hydrophone streamer with 3.125 meter group spacing. Data were corrected for sub-bottom profiler tow depth, converted to envelope, swell corrected and muted above the seafloor. Navigation was converted from seconds of arc to UTM zone 11N.

Process_Date: 20180718

Process_Step:

Process_Description:

MCS profiles were processed using SIOSEIS and Echos seismic software. SIOSEIS processing included conversion from SEGD to SEGY and geometry. Echos processing included trace kills, FK filter, NMO, spherical divergence gain, three trace runmix, 80-1200Hz bandpass filter, automatic gain control, two passes of static correction, water column mute, deghosting, stack, gap and spiking deconvolution, post stack time migration, and a post-stack FX deconvolution. Navigation was converted from seconds of arc to UTM zone 11N.
