Figure 1. Locations of all cores from United States Geological Survey cruise 2008–008–FA (SJ8), archive samples, and names of significant bathymetric features. The SJ8 cores are labeled by number (such as 11, rather than the full core name of SJ8–11GGC) and either a green circle (representing a sampled core) or a blue circle (representing bagged samples from core catcher only), whereas the archive cores are labeled by full core name and a red circle. |

Figure 6. Example of a gravity core summary sheet from core SJ8–20GGC, obtained on United States Geological Survey cruise 2008–08–FA aboard the National Oceanic and Atmospheric Administration research vessel Seward Johnson. Summary sheets include core location, lithology, color, grain-size, wet-bulk density, and magnetic susceptibility data. |
