To provide radiographs of some of the cores collected on USGS Field Activity 2008-008. The radiographs highlight sedimentary structures, especially bioturbation and the fine tails of turbidites.

Data sources used in this process:
Due to the confusing naming convention, these images were checked over and over to make sure the naming convention matched the actual interval being described.
These data represent all the cores that were radiographed. Some cores were not radiographed due to core length and (or) time constraints. Radiographs are available for cores 5, 7, 8, 9, 13, 17, 18, 20, 21, 22, 33, 38, and 40. Core 33GGC ran past the ruler so the last section interval is approximated. The bottom section of core 38GGC was not scanned.
The file naming convention is as follows: CCCC_SSSSS_I. CCCC is the core number (ie 5GGC), SSSSS is the section number (ie sect1), and I is the interval number (ie 1). Section number increase from bottom of the core to the top of the core, while interval numbers increase from the top of the core to the bottom and start over at 1 in each section. The exception to this naming convention is the additional file in core 5GGC, which is the core cutter section at the very bottom of the core and has the filename 5GGC_cc_1. Instead of offering a composite JPEG with all of the individual intervals compiled and aligned, the radiographs are offered as individual intervals. This is due to the fact that when the radiographs are taken, the outer edges decrease in accuracy and therefore lying one edge on top of the other creates inaccurate composites.
An example of a core and the order of the images from top to bottom is as follows:
5GGC_sect2_1 5GGC_sect2_2 5GGC_sect2_3 5GGC_sect2_4 5GGC_sect2_5 5GGC_sect1_1 5GGC_sect1_2 5GGC_sect1_3 5GGC_sect1_4 5GGC_sect1_5 5GGC_cc_1
