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. Purpose: This table provides the ages acquired by performing radiocarbon testing on 19 cores (8 from 2008-008-FA and 11 cores archived by LDEO).

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_Step: Process_Description: 19 cores (8 from 2008-008-FA and 11 from LDEO) were sampled for foraminifera at 1.5 to 2 cm thick intervals at submarine landslide deposits and above or below turbidites. These samples were washed over a 63-micron screen, dried, and then picked for datable species (Globigerinoides ruber, Globigerinoides sacculifer, and Globigerinella aequilarteralis). After being picked, the samples were washed and then sent off for dating.

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.
