Notes:

1. Channels clearly recognized by V-shaped truncations of underlying reflections, and by "sagging" reflections of channel fill.
2. Depth values on seismic profile assume a seismic velocity of 1,600 m/s.

Sources:

- USGS seismic-reflection data (Sliter et al., 2009).

- Project DEM compilation v2013.07. Bathymetric contour interval is 10 m.

Heavy contours are 50 m isobaths.

- Project DEM compilation v2013.07.

- Traces of Point Buchon fault from PG&E (2012).

- Fugro 2D and 3D seismic-reflection data (Fugro, 2012).

- USGS 2D seismic-reflection data (Sliter et al., 2009).

- Selected faults compiled from PG&E (2012, 2013).

Notes

1. Colors on individual tracklines represent depth of original channel interpretation on that line. Gridded and contoured surfaces between tracklines are interpolated to help visualize channels. However, channel geometry is not constrained between seismic profiles.
2. Contours within channels mapped from seismic data are on 5 m intervals.
3. Channel width is measured across the channel on individual seismic profiles between the breaks in slope between the incised part of the channel and the surrounding surface (the shoulders). Because these breaks in slope are often gradual, the channel width measurements are approximate. Channel grids include channel shoulders.
4. Channel depth is the depth of thalweg incision below the surrounding surface (channel shoulder).
