Description:

Abstract:

This dataset includes swell-filtered, high-resolution seismic-reflection data jointly collected by the U.S. Geological Survey (USGS) and Oregon State University in 2012, between Punta Gorda and Fort Bragg in northern California.

Purpose:

These data were collected as part of USGS efforts to better understand the northernmost section of the San Andreas Fault Zone. 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 activity from which these data were derived is available online at:

Process_Description:

Seismic-reflection SEG-Y files were corrected for swell effects using Sioseis software (see: http://sioseis.ucsd.edu/procs.html). SEG-Y header data were normalized using the "header" Sioseis processes, and a band pass filter was applied. Next, each SEG-Y file was displayed using Seisee (available at http://www.dmng.ru/en/freeware.html) and up to 16 water-bottom time/shot-point pairs where recorded to guide the automated water-bottom picker used to mute the water column. Finally, a swell filter was applied to the data, and the results were exported as a new SEG-Y file. The following parameters were used each process:


header: fno 0 lno 9999999 ftr 0 ltr 99999 l4 = l3

header2: fno 0 lno 99999 ftr 0 ltr 99999 r59 = r50

filter: ftype 0 pass 160 1600

water bottom picker: solrat between 2-5 ses 0  0.002 sel 0  0.5

swell: n 35
