Description:

Abstract:

High-resolution chirp sub-bottom data were collected by the U.S. Geological Survey in April 2011 south of Bainbridge Island and west of Seattle in Puget Sound, Washington. Data were collected aboard the R/V Karluk during field activity K0211PS using an Edgetech SB-512i sub-bottom profiler. Sub-bottom acoustic penetration spans several tens of meters and is variable by location.

Purpose:

Data were acquired to support the USGS Catastrophic Coastal and Marine Hazards Program to aide hazard assessment of the Seattle Fault zone in central Puget Sound. Data were collected to image a backthrust fault scarp and surrounding areas to determine locations of thicker sediment piles that contain long earthquake records. 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:

Quality control was conducted during data acquisition and quality was assured during data processing

Logical_Consistency_Report:

No formal logical consistency tests were conducted, but quality control was conducted during 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 3 m 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.

Lineage:

Process_Step:

Process_Description:

Chirp sub-bottom data were collected using an Edgetech-512i sub-bottom profiler. Data were corrected for sub-bottom profiler tow depth, converted to envelope, and bad navigation fixes were removed. Navigation was converted from seconds of arc to decimal degrees.
