Attribute_Accuracy_Report:
Attributes were double checked that file name was in fact the correct core that the data belonged to.
Logical_Consistency_Report:
The file naming convention is as follows: CCCC_mscl. CCCC stands for the core name which is ##GGC, GGC stands for giant gravity core. MSCL stands for multi-sensor core logger. There are 2 files for each core: 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. The core name is only marked in the file name, so take caution if renaming files.
Completeness_Report:
These data represent all of the cores that were analyzed with the GEOTEK MSCL-S. 19 of the 20 2008-008-FA cores yielded usable MSCL data. There is MSCL data for core: 5, 7, 8, 9, 10, 12, 13, 17, 18, 20, 21, 22, 23, 24, 31, 33, 34, 38, and 40. The only core without MSCL data is 28GGC, this core had only about 7 cms of readable data, and therefore it was not included.

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.

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

Process_Description:
Once back onshore physical properties were collected from the split sections of the SJ8 cores using a GEOTEK MSCL-S multi-sensor core logger. The cores were analyzed at ambient room temperature (20-25 degrees Celsius). Gamma-ray attenuation (wet-bulk density) and magnetic susceptibility were measured at 1-cm intervals for each core with a 10 second count time.

Process_Description:
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 lines had errors in only one parameter, these data points were flagged, but they were not considered erroneous, therefore they were not removed for corrected depth.

Process_Description:
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.
