In 2008, as a collaborative effort between Woods Hole Oceanographic Institution and the U.S. Geological Survey, 20 giant gravity cores were collected from areas surrounding Puerto Rico and the U.S. Virgin Islands. The regions sampled have had many large earthquake and landslide events, some of which are believed to have triggered tsunamis. The objective of this coring cruise, carried out aboard the National Oceanic and Atmospheric Administration research vessel Seward Johnson, was to determine the age of several substantial slope failures and seismite layers near Puerto Rico in an effort to map their temporal distribution. Data gathered from the cores collected in 2008 and 11 archive cores from the Lamont-Doherty Earth Observatory are included in this report. These data include lithologic logs, core summary sheets, x-ray fluorescence, wet-bulk density, magnetic susceptibility, grain-size analyses, radiographs, and radiocarbon age dates.
This data set contains summary descriptions (JPEG) for the 20 cores collected in 2008 on the R/V Seward Johnson during field activity 2008-008-FA. These descriptions were created in LogPlot 7 and represent descriptive core information including: color, lithology, samples taken, mean grain-size, grain-size distribution, wet bulk density, and magnetic susceptibility.

Example of core summary description created in LogPlot 7 from core SJ8-5GGC
JPEG
Microsoft Windows Vista Version 6.1 (Build 7601) Service Pack 1; ESRI ArcCatalog 9.3.1.4095
Files were double checked that filename matched the core that was described and that all data came from the same core.
The naming convention is: CoreName_summary. The core name is the core number paired with the abbreviation GGC, which stands for giant gravity corer (##GGC). Summary stands for summary descriptions created in LogPlot 7.
This report contains all of the summary descriptions from the 2008 SJ8 cores. There were 20 cores with summary descriptions: 5GGC, 7GGC, 8GGC, 9GGC, 10GGC, 12GGC, 13GGC, 17GGC, 18GGC, 20GGC, 21GGC, 22GGC, 23GGC, 24GGC, 28GGC, 31GGC, 33GGC, 34GGC, 38GGC, and 40GGC. There are missing numbers due to failed core attempts or a site that only yielded a bag samples. Also, not all fields are applicable for each core. For some cores, some samples were not taken or tests not performed, therefore there is no data represented in the respective fields. 10GGC, 12GGC, 34GGC and 40GGC lack grain-size information. 28GGC lacks multi-sensor core logger data (wet bulk density and magnetic susceptibility).

GGC
The gravity cores collected during U.S. Geological Survey field activity 2008-008-FA. The Woods Hole Oceanographic Giant Gravity Corer (GGC) was used to collect the 20 cores in 2008. The gravity corer is a large diameter (10 centimeter) sampler that collects cores up to 6.5 meters in length. During field activity 2008-008-FA the corer was not rigged with liner longer than approximately 3 meters. Although cores were attempted at 40 core sites, core was recovered at only 20 sites. Seven additional sites yielded only samples (bagged) from the core catcher or cutting head. Of the 20 successful cores, three also have cutter/catcher bag samples.
Jason D. Chaytor examined the cores at the U.S. Geological Survey in Woods Hole at a centimeter scale. Hand-written observations were made of sediment type, notable bioturbation, shells, texture, color, stiffness, and additional features described in the core field descriptions.

Data from hand-written logs, grain-size and multi-sensor core logging were entered into LogPlot 7 for each core. LogPlot 7 created a mean-grain size plot, as well as graphically represented the grain-size distribution. LogPlot 7 also created plots for the wet-bulk density and magnetic susceptibility data. Hand-written logs were graphically represented by lithology symbols, color text, and location where samples were taken.

Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). Added additional online links in the Identification section. Updated a cross-reference citation to go from "in prep" to published. Fixed a link to data in the entity and attribute overview section. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.

Depth of core in centimeters
Units of measure: centimeters
>>Lithology
Symbols representing the lithology of the core. No data is represented by blank intervals. Symbology is denoted in the legend in the JPEG headers.
>>Color
Color of core interval based on the Munsell Soil Color Chart (2010).
>>Samples
What and where samples were taken.
S=Smear Slide
G= Grain-size
>> Mean Grain Size (Phi)

Unites of measure: phi
>>Grain Size Distribution
