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.
To provide xls and csv files of x-ray fluorescence data from 12 cores collected during USGS Field Activity 2008-008-FA from offshore Puerto Rico and the U.S. Virgin Islands. There are separate tables for each individual core and sometimes per each section.
For more information on the USGS cruise, please see https://cmgds.marine.usgs.gov/fan_info.php?fan=2008-008-FA.

Attributes were double checked that file name was in fact the correct core that the data belonged to.
The file naming convention is as follows: CCCC_SSSSSS_XRF. CCCC stands for the core name which is ##GGC, GGC stands for giant gravity core. SSSSSS stands for the section information. Some files are only one section, some are multiple and some include the core catcher (examples below). XRF stands for x-ray fluorescence. There are 2 files for each core or section: an XLS and a CSV. The same data is in both tables, the only difference is that the CSV file marks erroneous data points with an (*) and the XLS table marks erroneous data points by putting the text in red.
File Naming Examples:
>> 5GGC_sect1_cc_XRF Core 5, Section 1 and Core Catcher
>> 5GGC_sect2_XRF Core 5, Section 2
>> 10GGC_sect1_XRF Core 10, Section 1
>> 9GGC_sect1&2_XRF Core 9, Section 1 and 2
>> 38GGC_sect3_XRF Core 38, Section 3
This data represent all of the cores that were analyzed with an ITRAX micro-XRF scanner. 12 of the 20 2008-008-FA cores yielded usable x-ray fluorescence (XRF) data. There is XRF data for core: 5, 7, 8, 9, 10, 13, 17, 18, 21, 22, 33, and 38.

ground condition of core collection
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.
Each core was cut into sections on the ship after collection. The cores were then split into halves back onshore.

Once back onshore XRF geochemical measurements and linescan images of selected cores were acquired at a 1-millimeter (mm) resolution using an ITRAX micro-XRF scanner equipped with a 3-kilowatt (kW) molybdenum (Mo) target tube. The XRF scanning yields element intensities from the surface of split sediment cores that provide statistically significant results (greater than 100 counts per second) for potassium (K), chlorine (Cl), calcium (Ca), manganese (Mn), iron (Fe), strontium (Sr), zirconium (Zr), and argon (Ar) . Whole-element counts are provided in this data release rather than ratios of element counts (Lowemark and others, 2010).

Erroneous data points caused by the beginning and end of sections were flagged by either marking the text red (XLS) or adding an (*) for the CSV table. Some bad data points were marked with a ~ (CSV) if they were not caused by the beginning or end of sections, and corrected depth did not reflect their removal. No data values are any value of a -1.

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. The source information was incomplete and had to be modified to meet the standard. Fixed a link to data in the entity and attribute overview section. Minor fixes to the attribute format for some attributes were needed to meet the standard. 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.
