Description:

Abstract:

This data release contains 41 chirp sub-bottom profiles that were collected in February of 2016 from the Catalina Basin offshore southern California by the U.S. Geological Survey Pacific and Coastal Marine Science Center in cooperation with the University of Washington. Data were collected aboard the University of Washington’s R/V Thomas G. Thompson on USGS cruise 2016-616-FA. Chirp profiles were collected to image the Catalina and San Clemente fault systems as well as the San Gabriel Canyon system.

Purpose:

Data were acquired to support USGS geologic hazards projects to aide hazard assessment of southern California’s offshore Catalina and San Clemente fault zones. Data collection was funded by UW Student Ship Funds. High-resolution multichannel seismic-reflection data, high-resolution multibeam bathymetry, and backscatter data (Dartnell and others, 2017) were collected coincidentally. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report: Identified as the best available version

Logical_Consistency_Report:

Chirp subbottom data were collected during USGS field activity 2016-616-FA using a hull-mounted Knudsen 3260/320BR operated with a 3.5kHz sweep at 10KW power. Quality control was conducted during the collection process. Note that the Knudsen auto-water bottom tracker sometimes lost the seafloor and recorded the water column. Delay header can be found in byte 109.

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. Deep water delay header values are recorded in header byte 109.
